Creating an Epidemic of Health Collected papers Tom Munnecke Assistant Vice President Science Applications International Corporation 10260 Campus Point Dr. San Diego, CA. 92121 munnecket@saic.com Heather Wood Ion CEO Visiting Nurses Association Orange County, CA. hion@earthlink.net September 2000 Jonas Salk concluded that we need to “create and epidemic of health” to resolve many of the world’s health problems. He said, “Only a few are needed to visualize and to initiate a process that would become self-organizing, self-propelling, and selfpropagating, as is characteristic of evolutionary processes.” These papers explore this concept, in light of recent global changes in communications technology and our understanding of self-organizing systems.

The contagion for this epidemic is healthy people. In any population, there will be some who have maintained their health, and serve as role models for those who have not adapted as well. These people may be healers, or simply people who exude enough vitality that others can benefit. Healthy people are contagious in face to face settings. The Internet can leverage their presence around the globe. The vector of this epidemic is information. It can build electronic communities, share research, communicate knowledge, locate resources, share needs, and build an evolutionary path to cope with future needs. In order for this to be shared, access to the network must be global. The world can be the population affected by this epidemic. As a result of the herd effect, even those without direct access to the network can benefit. The virulence of the epidemic of health can be assured because of the universal need for health. Improving health can be a win-win situation for all concerned. Health is not a commodity subject to supply and demand curves; neither is information. The hospital, said Peter Drucker in 1973, is “one of the most complex social institutions around.”3 Systems of hospitals are even more complex. The intervening twenty-two years of technology, health care reform, and cost pressures cause even greater complexity. Compounding these levels of complexity are global issues which make the problem of global health care seem insurmountably complex. From a traditional point of view, perhaps they are. This complexity can be addressed by innovative techniques. By combining the dynamics of an epidemic with global communications, major changes can occur. To quote Salk: “Only a few are needed to visualize and to initiate a process that would become self-organizing, self-propelling, and self-propagating, as is characteristic of evolutionary processes.”4 The Internet as a Role Model The Internet serves as a role model for a self organizing, self-propelling, self propogating system of immense complexity which has grown rapidly over the last 25 years. It connects an unknown (30 million?) number of people from over 100 countries with millions of computers. The World Wide Web is a particularly active portion of the Internet, and is currently growing at about 1% per day. All indications are that the rate of growth of the Internet is accelerating. The Internet grew from a small set of universities, and developed with a (then) unique design attitude. Rather than convene committees and authoritative bodies to write white papers and standards, they adopted a philosophy of “rough consensus, running code.” As new ideas emerged, they would be discussed in various task forces. When the 1 Munnecke, Tom, and Ion, Heather, published in US Medicine Magazine, August, 1995 Interviewed by Bill Moyers, in The World of Ideas 3 Drucker, Peter, Management, Tasks, Responsibilities, Practices, Harper and Row, 1973, p. 4 2 4 Salk, Jonas, Anatomy of Reality, Columbia University Press, NY, 1983, p. 122 2 idea was deemed reasonably well formed, someone would program it and place it on the Internet. The good ideas survived and propagated; the bad ones died away. The Internet’s complexity evolved over the years from a simple initial condition and a well defined fitness function: replicating good ideas. A traditional approach to managing complexity, which harkens back to the “Clockwork Universe” thinking of Isaac Newton and his contemporaries, is to break things down into components, and resolve the complexity of each subcomponent. This cognitive divide and conquer approach has worked for many problems which are mechanistic or factory-like. For the sake of discussion, we contrast two types of systems: policy based and adaptive. A policy based system is controlled by an external set of rules, policies, or other control mechanism. The system is governed by negative feedback: operations which are against the policy are punished. The IRS tax code, driving laws, and bureaucratic organizations are examples of this approach. The complexity of these systems is restricted by the complexity of the policy; stability is generally considered a virtue. The more complex the system, the more complex the policy. The system is supposed to be predictable and behave repeatably, according to linear mathematical models. The role model for behavior is the policy, and authority is an abstraction of the hierarchy. In general, the goal of policy based systems is complex initial conditions, simple operation. An adaptive system is controlled internally by positive feedback. Successful operations are replicated. The system is assumed to be continuously changing and growing. The system is its own definition, and complexity is a characteristic which evolves over time according to the evolutionary “goodness” of the behaviors of the system. Adaptive systems are not necessarily predictable, and display emergent properties, in which the whole is greater than the sum of the parts. These systems are non-linear, and display patterns of chaos. Any living thing, evolution of the species, and the Internet are examples of adaptive systems. In general, the goal of adaptive systems is simple initial condition, complex operation. Consider the complexity of two problems: building a factory and tending a garden. A factory (policy based system) is a very complex system, with many rules and procedures for producing its products. If everything goes well, it will produce exactly what it was designed for, no more, no less. A garden, as an adaptive system, can be a very simple system. With the proper amount of water, seeds, nutrients, and sunlight, a respectable garden may appear. The results of the process are far less certain, and biological surprises may often appear. The simplicity of the garden, however, hides an incredible complexity of the chain of life. Even the smallest cubic millimeter of the garden holds immense scientific complexity and evolutionary information. Those tending the garden, however, are free to deal with simplicity. So it is with the complexity of global health. Rather than considering it to be a problem solved by the policy-based “factory” paradigm, it can seen as an adaptive problem akin to tending a garden. The immense global diversity of health care needs, resources, and models dictate that a highly adaptive and continuously growing system is necessary. A formula for designing adaptive systems might be: 3 Start simple, and let the system grow in complexity over time Allow it to evolve based on positive feedback. Replicate success. Decentralize to allow many points of view Support lateral communications for operations, training, and the evolution of the system Assume that the system is constantly changing; expect the unexpected. Alvin and Heidi Toffler wrote, “global competition means that we cannot go back to the conformity, uniformity, bureaucracy and brute force economy of the assembly-line era. But the Third Wave is not just a matter of technology and economics. It involves morality, culture and ideas as well as institutions and political structure.”5 The Internet as an Infrastructure As we move towards a global information infrastructure, we will once again experience the sensation that the world is shrinking. Concepts of distance, time, geography, borders, nationality, and community will all shift radically as we deal more and more with bits of information instead of atoms of matter. Globalization means much more than “Internationalization.” For the purposes of this article, we will define globalization as the process of dissolving borders. Connecting two medical facilities in the same town in the United States or connecting United States and Zaire are two variations of the same problem of globalization. (Although the Zaire problem is probably simpler.) The Global Health Care Environment There are three major aspects to the challenges of the globalization of health care: the definition of “health," and the pragmatic understanding of implications for care the diversity of health care models the different drivers of health care The Definition of Health The World Health Organization states “Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity.”6 The problem with this definition is that by including the words ‘complete’ and ‘social wellbeing’ it turns the enduring problems of human happiness and social interaction into one more medical problem to be treated by specific, scientific, interventions. Coupled with the mechanistic and reductionistic expansions in technologically-driven capacities, this opens a Pandora’s box of demands for ‘fixes’. Further, the definition’s interpretation has removed the responsibility for such complete well-being from the individual and placed it on the shoulders of the medical professional. This definition does not convey the common world-wide assumption that health is a functional state which makes possible the achievement of other goals and activities of 5 Toffler, Alvin and Heidi, Creating a New Civilization, The Politics of the Third Wave, Turner Publishing, Atlanta, 1994, p. 36 6 Callahan, Daniel, What Kind of Life, Simon and Schuster, NY, 1990, p. 34 4 living. Comfort, well-being, and the distinction between physical and mental health differ in social classes, cultures and religious groups.7 Attached to the definition of health is the consequent health policy in any given community. If health is defined as a right of all people, access to health care is mandated. If it is defined as a market-driven commodity, or as an individual’s responsibility, access to health care services varies widely. Models of Health Care In 1990 Americans spent $10.3 billion on alternative health care modalities.8 In 1992 Congress created the Office of Alternative Medicine as part of the National Institutes of Health. Even as we cannot assume that there is only one medical model used within the US, we cannot assume that globalization through communication will dissolve the boundaries between definitions and models. 48% of the world’s population is at risk for the biggest international killer, malaria, and over 200 million people live in areas where malaria is endemic.9 Yet for most of these people malaria is a condition of life, a given, and thus not a reason to seek any model of care. Major models of care around the world include: Model Region Allopathic or diagnosis-based therapies Western, professional medicine Homeopathic or likeness-based therapies European Meridian or energy based therapies Asia, and increasingly in the US Manipulative or treatments by the hands World-wide Shamanistic or treatments by priests Indigenous peoples, and folk healers Ayur-Veda or balance restoring therapies India Herbal or plant-based therapies World-wide Even within one of these models of care, such as Western diagnostic medicine, various interpretations of the disease process and of the healing or curative process mean that specialists may differ not only in what they do, but in their perspectives on what constitutes disease, health, and an ethically justified intervention. Where the medical model has coexisted with highly scientific societies, the habitual ‘need’ for certainty has insured a ‘need’ for specialized technology which has created a ‘need’ for specialized personnel.10 Health Care Drivers Delivering care involves a complex interaction among individuals, providers of care, payors and communities. In some models, the individual receiving the care is not the payor. In some models the patient is not the object of the care. In some models the 7 Hanlon, John J., Public Health, Mosby, St. Louis, 1974, p. 73 Reader’s Guide to Alternative Health Methods, American Medical Association, Chicago, 1993, and Harvard Medical School report to the New England Journal of Medicine on “unconventional” medical therapies pub. 1993 9 Segal, Gerald, The World Affairs Companion, Simon and Schuster, NY, 1991, p. 86 10 Bursztajn, Harold, Feinbloom, Richard, Hamm, Robert, Brodsky, Archie; Medical Choices, Medical Chances, Delacorte Press, NY, 1981, p. 428 8 5 physician or provider of care must satisfy at least three masters: the patient, the payor, and the community. Different groups balance these influences in contrasting ways. Some of the drivers of health care services are: population economics social responsibility or humanitarian concerns environment including sanitation, water, natural resources war culture, beliefs, values innovation fear and legal systems of protection These factors influence the content of care, the compulsion or impulse to seek it, and the responsibility to pay for it. In the US the movement to reform health care must somehow balance the demand for universal access to care, and the demand to limit the costs of care. Both problems may be clarified by better understanding of the definitions of health and of disease and the consequent demands for care itself.11 Our Shrinking World The challenge to global health care is a volatile mix of pressures from population, poverty, new and drug-resistant pathogens, natural and man-made catastrophes, wars, environmental degradation, mass travel, and extraordinary demand for medical solutions to non-biological problems. HIV, hepatitis B, Ebola bacteria, or new threats to global health exist independent of society’s differing health care models. Partly due to these pressures, the health care community has been scaled up to proportions greater than any nation-state or economic organization. In some countries the health care delivery system is the largest employer, and the largest recipient of hard currency. The World Bank has become the major external funder of health sector investment in developing countries.12 Simultaneously, multinational companies are looking to developing markets with major consequences regarding health care. Since 95 % of world leaf tobacco is controlled by six transnational corporations, their power can often overwhelm countries which do not have a clear tobacco policy, or where significant revenue is gained from tobacco sales or exports. The tobacco company viewpoint is clear: “Until recently perhaps 40% of the world’s smokers were locked behind ideological walls. We’ve been itching to get at them--and we’re much relieved and excited that this 40% is now open to us. That’s where our growth will come from."13 11 Castro, Janice, The American Way of Health, Little Brown, NY 1994, p. 112 Walt, Gill, Health Policy, Zed Books, London, 1994, p. 127 13 Walt, op cit., p. 146 12 6 With global marketing has come global consumerism. From consumer action, the International Code regulating the marketing practices and promotion of infant foods was passed by 118 countries at the World Health Assembly in 1981.14 There is no single, stable point of view in this expansion of activity, need, and awareness on which to base a policy. With the huge numbers of degrees of freedom and the explosion of human needs, a complex, adaptive, interacting web approach is necessary to address the global commonality of concern for health. Changes to the Practice of Health Care We will discuss the worldwide impact and potential of the changes of perspective which result from the decentralizing, harmonizing and empowering qualities of digital interaction.15 Decentralization and Replications of Success A transition to adaptive systems would provide an opportunity to evaluate policies which effect global health applied at the local level. Enteric disease remain rampant worldwide, and the safety of water supplies is a problem relevant in both the developed and developing worlds. For almost two decades, solar disinfecting studies have confirmed that bacteria from fecal sources which contaminate water are susceptible to destruction upon exposure to sunlight for an adequate period of time. Drinking water can therefore be rendered safe using clear plastic or glass bottles when exposed to sunlight for 85 minutes.16 Communicating this simple solution to highly motivated local users of the Internet and World Wide Web, would create the opportunity to save the lives of over 25,000 children per day, by transformation of a “push” effort by world bureaucracies and external organizations to a locally empowered “pull” operation of relevance. The practice of medicine is an application of local knowledge. While a physician’s discrimination will be informed by aggregate numbers of efficacy of test results and appropriate drugs, the more local his attention to the circumstances of illness and health, the more relevant the care provided will be. Decentralization of communication means immediate comparisons of the local conditions of care without the diluting, and often distracting, delays of the centralized systems of distribution and approval or codification of validity. How can the decentralized worldwide communications technology effect policy change? Greater knowledge means greater informed choice, and the connectivity of a global information infrastructure indicates that choice can be based upon the fitness function of efficacy. What works best? What does no harm? Centralized policies can now subject to the democratic and informed scrutiny possible with shared knowledge based on an intellectual commons which accelerates and enhances our ability to correct error and revise health care delivery on the basis of what is known to have positive effect without negative consequence. 14 The sole opposing vote came from the United States on the grounds of a perception of interference in global trade, but this was viewed as due to the twelve companies which control the bulk of the world infant milk market. ibid., p. 139 15 Negroponte, Nicholas P., Being Digital, Knopf, NY, 1995, p. 229 16 Solar Disinfection of Drinking Water and Oral Rehydration Solutions, Guidelines for Household Application in Developing Countries, Department of Environmental Health, American University of Beirut, UNICEF, 1984--to present. 7 The mechanistic paradigm driving Western medicine has proven inadequate for preventive care, chronic conditions, and behavioral medicine. Market-based values of cost have not reflected the human and long-term impacts of this inadequacy. The complex adaptive systems approach of communications technology makes it simple to relate what we now know to our choices of what we must and can do. Communications connectivity thus restores to medicine its moral role, and restores medical judgment to primacy above measurable evidence. An informed patient, just as an informed community, or country, can assume cooperative responsibility with the physician and scientist to choose optimally, instead of passively expecting the physician or medical profession to provide complete well-being. In such areas as infant mortality, the use of prenatal care, and the coordination of community resources, dialogue among providers offers potential improvement through alternative approaches known to be successful.17 Connectivity and Diversity Another opportunity provided by the globalization of a complex adaptive information technology, is the connectivity of shared interests and the harmonies thereby created among diverse users, from diverse cultures and perspectives. One of the most expensive consequences of the mechanistic paradigm in health care is its compulsion for certainty.18 Not only does interactive connectivity educate us regarding other possibilities, but in doing so it increases our tolerance both for diversity and for the uncertainties of organic and adaptive systems. Such an attitude could radically change cross-cultural health care, and the delivery of support or compassionate care. This tolerance and mutualism is enhanced by another function of digital communication--the exploration of free movement between generalities and specifics. As the depth/breadth problem disappears with hypertext, traditional accusations of “inadequate” or ‘insufficient’ regarding data become irrelevant, as the user can at once see the fitness function: what works, where, when and how much is known about why.19 In all aspects of health care this creates an accessibility for experiment, evidence and evaluation. Research will no longer be an additional luxury, but intrinsic to the process itself. Simultaneously, connectivity eliminates the boundaries between knowledge of need and knowledge of resources. In global health care this is particularly significant since we know that most famines, some epidemics and many untreated septic infections result from distribution problems (information) not by lack of knowledge.20 By using the The Women’s Health Data Book, 1995, Jacob’s Institute, Washington, DC, p. 140--use of prenatal care has declined in the United States which ranks 19th in infant mortality among 33 industrialized countries. 18 35% of Medicare spending is for “futile” medical help which can neither save a patient nor extend lives, approximately $100 billion per year is spent on wasteful tests of so-called defensive medicine, which served only to show that the tests themselves were done, and another $100 billion per year is spent on paperwork to justify what was done. Castro, op cit., p. 30-32 19 Negroponte, op cit., p. 69 20 In May 1995 a group of women in Atlanta, Georgia learned by FAX of the dire need for specific drugs in Sarajevo, and were able to deliver forty-six pieces of luggage filled with antibiotics which will prevent amputations of children’s limbs because of gangrene. Such grass-roots responses apply to the magnitude of global needs with the immediacy of Internet awareness. Reported ABC news, June 9, 1995 17 8 electronic web connecting common concerns, we can better respond both more rapidly and more appropriately than the hierarchical paradigms of the past have allowed. How to create the epidemic of health on the Internet The first signs of this epidemic are already appearing on the Internet. Patient support groups, for example, have been shown to have a life extending effect in cancer therapies, chronic illnesses, HIV positive individuals, and chronic heart disease.21 22 Extending these activities to on-line communities on the Internet could provide vast benefits. The BRAINTMR Internet support group, for example, was started by a young woman who had a brain tumor successfully removed. As a survivor of this traumatic experience, she is a powerful communicator to a group of people facing similar problems. This group of 600 people from all over the world “meets” via electronic mail and shares their experiences and emotional ups and downs as they struggle with this common problem. The group simply emerged: it has no formal sponsorship or funding. (The originator of the group, Samantha Scolamiero can be reached at SAMAJANE@MIT.EDU) Geriatric medicine has struggled with the fact that a significant portion of elderly patients seek medical care due to loneliness and boredom. Linking isolated, often homebound elderly patients to each other via the Internet could have a significant impact on social interaction, a sense of worth, and the related sense of well-being.23 1. 2. 3. 4. 5. 6. 7. Start Simple. Couple a simple mechanism with a grand vision. Devise a mechanism for communicating and replicating success. Provide universal access to the global information infrastructure. Build connectivity and virtual communities for health-related activities. Support Patient Support groups on the network. Publish medical knowledge on the Internet, make it freely available to all. Create a health “metacenter” on the World Wide Web to serve as a focal point for the evolution of the epidemic of health. We believe that global communications can initiate an epidemic of health which can be self-organizing, self-propelling, and self-propagating. In the event of a global biological emergency, global communications could prevent or mitigate a catastrophe. As a means of improving one of humanity’s intrinsic needs: health, it could become a powerful source of positive reinforcement. As a means of aiding and comforting those suffering from disease, it could build community where none was previously possible. All that is necessary is to trigger this are those few people to visualize and initiate the process. 21 Simonton, Carl, et al, Getting Well Again, Tarcher, Los Angeles, 1978.

This is reminiscent of Jonas’s charge to me in 1988 to translate his stream of consciousness diaries into a cogent philosophy for our time, and into practical tools to change individual lives, organizations and communities. Bill Moyers named this philosophy “The Science of Hope.” My words today are an attempt to convey his thoughts in the context of our meeting. “Why postpone into the future what can be done in the present?” Jonas asked at the celebration of the Year of the Child at the United Nations in September 1994. This is his challenge to us today. We have the tools, we have the resources, but do we have the necessary and sufficient desire to apply our responsibility and create a future of health? Can we in fact, get to an epidemic of health from here? In health care we are at present united only by our mistrust. Further, individuals do not view themselves as their own best experts on health. Those of us who provide care are frustrated in an atmosphere of competition rather than collaboration, even though most of us know that to serve our communities well, we must cooperate. How can we become examples of co-operating, evolving, participants in community? An epidemic is a prevalence of something in a community at a given time. We all wish to transform what is prevalent at the moment— violence, chronic disease, and isolation—into a cooperative, tolerant, and constantly evolving commons from which we all gain support and for which we all feel responsible. The vector for an epidemic of health is information. One of our problems is that what data we have regarding health, not disease, is generally fragmentary and flawed. Further, the mere existence of data does not constitute either knowledge or meaning. To trigger a positive epidemic, individuals must find meaning in having informed choice, and in acting responsibly on behalf of health. Further, public health depends upon a sense of responsibility toward a common good. To create an epidemic of health, must we first form a community? Our first challenge is that of language. As we invert the dominant paradigm of command and control, of feudal hierarchy, of linear transaction, we must remember that our words reflect our perspectives, our perspectives create our actions and in consequence, our reality. In health care our words reflect both the confines of a particular tribe, and all too common moral greed of self-righteousness. The vocabulary represents the mind-set of dominance and dependence. We must discipline ourselves to speak today in new terms. Jonas obsessed like a bull with a matador over words. He preferred to speak in terms of agency rather than knowledge, and of concordance rather than governance. He worried at the growing decline of functional literacy in this country, because we know that literacy is the most effective intervention we can make for maternal/child health, and thus for the long term health of populations. When we speak of health, let us speak of optimal function, and of what we can imagine to evoke our own metamorphosis. Let us avoid the vocabularies of dependence, failure and combat, which now dominate discussions of health. Language not only Ion, Heather. Remarks presented at “Creating an Epidemic of Health” meeting in Washington, DC, May 3, 1999 24 10 conveys our philosophy of life, our assumptions regarding nature, purpose and values, but it defines the ways we relate one to another. Jonas perceived relationship to be the most fundamental phenomenon of the universe. In order to understand anything we must have a sense of the fundamental connections that form the backdrop of experience. The explosive growth of the Web can build human relationships, and the web structure can help us abstract the qualities of relationship. The metaphor of the web helps us to understand functional wholes of cooperation which are far greater than the sum of the parts. In terms of inverted perspective, the Web allows us to start anywhere in our explorations of self-generating forms. Jonas would caution us here to remember that the Web has exploded because its users are motivated by self-interest. We have yet to motivate self-interest and responsibility regarding preventive health choices on any large scale. When we talk of creating learning organizations, we need to recognize that the organizing principle itself is learning. Jonas would say that because life is dynamic, “each encounter evokes potential from every participant, each environment evokes new possibilities within the dynamics of each encounter.” In terms of a new vision for health, this means recognition of mutual interdependence and mutual responsibility. It also means hope, for the unknown becomes possibility. Our medical paradigm is one option among many, each of us is the best expert on our own health, and responsible for the effects we wish to cause. Causes can create remedies, and mind can change the efficacy of any process. “Complexity must have begun with the tendency toward complementary pairing. It then proceeded toward the pairing of minds, the pairing of asymmetrical elements to establish balance,” Jonas wrote in his book Anatomy of Reality. Our needs are satisfied not by our existence alone, but through relationships that are mutually reinforcing. We know from the successes of science that there exists a functional unity between reciprocating causes and effects. From the cellular level to gravitational field theory, interactive interdependence is the pattern of order. Mutuality is based on complementarity, and thus diversity evokes potential through constantly dynamic learning. The clinical success of buddy systems is well documented—by the geriatric program at Boswell Hospital in Arizona, by the Birth Project in Sacramento, by “Sweet Success” of the American Diabetic Association. Buddy systems help transform organizations by expanding skills, streamlining work flow, and building ownership in performance. Mutuality can be applied to our uses of knowledge, and our expansion of possibility. If we look to the studies of immunologic memory as well as the studies of individual and social resilience, we see that every unit of life constantly transforms knowledge into action. Communities recover from catastrophe, such as famines, in direct relation to the knowledge of opportunities available to them. Knowledge is an experience not an action. Most smokers know tobacco is not good for them. What is lacking is the incentive for change. A data base is only as useful as the motivation of users converts that data into meaning. Jonas would say that the answers already exist, it is our job to find the right questions. We can enhance the positive without having to experience the negative because we can imagine alternatives. When we accept that our existing organizations and institutions have failed to solve most of our significant social problems, and move from that acceptance to responsibility for changing our organizations, we can apply Jonas’s 11 insights. We need a national data base describing the successes that have been achieved in support of health and community resilience, and we need to make our knowledge of imagined alternatives accessible to all. Since each individual exists in relationship to others, and since we live in groups, how do we apply a concept of mutuality to society? In Native American languages a healer is often termed a ‘designer.’ We can design our future in terms of the effects we wish to cause, or the purposes we wish to serve. If we use information to expand memory, whether we do so in terms of chronic disease or resilient communities, we free ourselves from mechanism, and from pessimism. Information must be configured in patterns appropriate to the source and the use, not merely appropriate to the tool. The web and the community effects it can support is a better abstraction for health than the measures of failure statistics. But the crux of this approach is openness—experimentation, inquiry, adventure for the purpose of transformation. If we are to design the co-evolution of mutually beneficial self-interest in which we acknowledge our interdependence and choose to sustain our shared purpose over time, then we must use connectivity to expand our capacities and our opportunities. We now have, in Sir Isaiah Berlin’s terms, the second type of liberty. We have achieved freedoms from, how shall we use our freedoms for? Jonas hoped that we would use what we know of health to achieve conflict resolution for groups in trouble. Conflict resolution among the constituents of our health care system is critically necessary. Can the VA serve as our laboratory for this experiment? How can the VA apply some of these concepts to the creation of ‘virtual health care organization’ as outlined by Kenneth Kizer? Can the self-interest of veterans become incentives for self-reliant health choices? We have seen how effective Gulf war veterans have been in using the web to generate support and eventual interventions regarding their experiences of symptoms. Instead of disease-support groups, can we learn from this same population regarding actions to support health? Many of us are involved in turning around a given organization, or some employees, or even, our own lives. We can achieve these turnarounds with understood methods, which begin with a chosen purpose, precisely expressed expectations, and persistent, visible function. To establish trust, we have first to become predictable. In our current environment, that in itself is a challenge. Trust is ambiguous, and must be reaffirmed through choice over time. Trust can be established by giving each other reasons to permit action. In our studies of childhood resilience we know that one of the contributing factors to resilience is the ability to reframe a given experience. In health care at present many of our issues of mistrust stem from the problems of authority— privileges granted, permitted actions—who you know, what you have, what you can do. Perhaps by reframing these problems of authority we may be led to new solutions, or better questions. In how many different ways can we reframe what the VA does, the roles it plays, the purposes it serves? If the hospital is no longer the axis of health care, what other uses can we envision for a national research, educational, and care-giving system? What would happen if we linked up our public library systems with our community resources for seniors with the VA? What successes do we wish to replicate? What knowledge can we use in other contexts? I think one of the greatest needs we have is to find out who is 12 doing what in terms of building community, where and how are they doing it, and with what result? What aspects of the VA and its services and constituents constitute community? Are these values transferable? How do we know? My excitement and my discomfort with our efforts to outline a new conceptual foundation for health care come from an awareness that we do not yet know what we know. What truly contributes to health? What sustains communities under stress? What languages enhance collaboration? Much of what we assume regarding health and health care, I believe is untested—merely assumption and habit, or convention. I believe that what we need at present a grand experiment—multiple approaches, multiple disciplines, tolerant hypotheses of paradox and participatory analysis. We need to use, as Jonas did, statistical variance analyses, not aggregates. If, as Jonas said, the basis of order is relationship, then let us truly examine the relationships of health. Of the health of the individual to the community, and of the health of the community to the individual. Can what we know be measured? Can what we know be replicated? The web can certainly help us design from the point of connectivity, and as a metaphor it can refresh and expand our knowledge of who we are and what we can do. It can be our mirror, and as such both tool and metaphor. Let me end by reminding you that Jonas’ science of hope outlines a process. He would call it the logic in the magic. We can become the agents of conscious evolution as we apply our sense of responsibility for the future to present needs. We seek concordance and resonance in our creativity. That is the first step toward making the dream of an epidemic of health a reality. Survival of the wisest depends upon whether we use our tools as good ancestors of the future. Jonas wrote: “Only a few are needed to visualize and to initiate a process that would become self-organizing, self-propelling, and self-propagating, as is characteristic of evolutionary processes.” 13 VValeo Organization Description “valeo” meaning, “to have the power to achieve vigor, health and wellness.” The Vvaleo initiative is a national effort to provide all individuals and communities access to information, services, and resources necessary to achieve optimal health. It will be a fair, group collective plan by all health-related partner, including individuals, health care providers, insurers, purchasers, employers, and other relevant groups. “THE VVALEO INITIATIVE” Creating an Epidemic of Health The Vvaleo Initiative began in 1999 with a small group of individuals representing public and private organizations committed to improving personal and public health. Jonas Salk’s phrase “creating an epidemic of health”25 best expressed the common vision. Contagion for such an epidemic is healthy people, while the vector for the epidemic is information. Vvaleo seeks to discover and encourage individuals and communities to create this epidemic of health by enabling a process and developing an organization to link person-centered health and care information, resources and services. In September 1999 140 community leaders, consumers, practitioners, educators, payers, policy makers and philanthropists met in Cleveland to clarify the principles of the initiative. Energetic discussion emphasized that no person should be unable to pursue health, information, and care because of limitations of employment, payment, or social conditions, especially since the science to improve and support health exists, and the means to connect individuals to the necessary information and communities of shared meaning has been developed. The principles that guide the work going forward are: 1. The pursuit of health and care is an individual undertaking, to which every person must have access, as well as an individual responsibility. 2. The rights, privacy and dignity of individuals will be respected in the use and management of personal health information not under their direct control. 3. Individuals have the right to receive and control a complete copy of their own personal health information. The phrase ‘to create an epidemic of health’ is a recurring theme in the writings of Jonas Salk M.D., who served as the conscientious editor of the publication in US Medicine in 1995 by Tom Munnecke and Heather Wood Ion, when he gave the authors encouragement to expand and use this phrase. 25 14 4. Vvaleo is an inclusive process, based on open, respectful and personal participation, and centered on personal definitions of health. 5. Vvaleo is self-organizing and self-governing, enhancing trust and public benefit. 6. The meaning of ‘an epidemic of health’ will be derived through the Vvaleo process and will continually evolve. As indicated in these Principles, the Vvaleo effort requires a new form of organization, one that transcends individuals and existing organizations and generates the confidence necessary to connect all parties and communities. Health care at present is united by distrust but cooperation based on mutual benefit can evolve through self-governance. The Vvaleo volunteers benefited from the resources of The Chaordic Alliance26 and its founder Dee Hock in facilitating the self-governance of complex initiatives. The volunteers have also used the techniques of Appreciative Inquiry developed by David Cooperrider in order to elicit positive conversations in a self-sustaining discovery process. Both are involved in the United Religions Initiative which over five years has brought representatives from all over the world together to form an inclusive organization serving the purpose: to end violence in the name of religion. The process of developing the shared meaning, principles of collaboration, and charter for the future in the URI establish a model of success for the creation of a transcendent effort uniting all peoples in the pursuit of health. While the first discussions of the present organization began through the interest of the Veterans’ Health Administration because of their drive to become a patient-centered organization, other non-governmental health constituencies rapidly became involved. Over the course of eighteen months, representatives from academic medicine, health care improvement institutes, patient advocates, providers, systems companies, and professional associations have joined the effort. Over $600,000 has been raised to sustain the collaboration and outreach to date. The participants at the September 1999 meeting, called “A Time for Decision” voted overwhelmingly in favor of moving forward. As one of the speakers stated: “I do not know if this will work, but I want my grandchildren to know that I was part of the beginning.” To sustain the development of an infrastructure supporting the effort, the group adopted the name Vvaleo from the Latin “valeo” meaning, “to have the power to achieve vigor, health and wellness.” It is incorporated as a not-for-profit 501 c 3 corporation, and the University of Texas Health Sciences Center at Houston serves as fiscal agent. The entity is not policy based, but driven by a sense of responsibility toward the common good expressed through an adaptive systems process. A primarily goal is to engage those who have not had access to the present system of care and to hear and respond to their values and needs. This is the dream to ‘lift every voice’. What remains to be done is to design the programs of the group, gain the trust of the participants, provide the information or create an individual knowledge base, and stimulate the transformative actions necessary to sustain health. The board of directors 26 The Chaordic Alliance was founded by Dee Hock, CEO Emeritus of VISA. 15 and the participants in various Vvaleo meetings have established three work groups to deal simultaneously and interactively with the following priorities: Design and form the self-governing organization. Conceive and initiate the national conversations about health, and help motivated users convert the data from these conversations into meaningful knowledge. Explore the means, and the ways to enhance trust for person-centered, open, confidential and secure exchange of health and health care information. As an inclusive effort, Vvaleo will work collaboratively to include all relevant and affected parties, and to enable individuals to make informed choices regarding what they need and want to support their health and care. The next step is a national meeting to bring this effort to the attention of a broader national audience and to begin the first conversations as Vvaleo defines and establishes a process for creating an epidemic of health. The Vvaleo Initiative invites your participation, contributions, and involvement. 16 Comments on the Thoughts of Jonas Salk27 Wednesday, June 21st was the fifth anniversary of Jonas' death, so as we struggled to deal with the pragmatism necessary to begin this great journey of the epidemic of health, I was joyous on his behalf, and mourning that he was not with us to share in the excitement. Since then, in the daily abrasions of the nitty-gritty, and the quiet of the weekend, I have been reflecting on what we found difficult, and on what lies ahead of us. There was tension between the conceptual basis for our work, and the housekeeping details of accountability and inclusiveness. Here are Jonas' thoughts on the subject: "I now see patterns of correlations as an aesthetic function and patterns of cause and effect as a reasoning function.... There is, or needs to be, a science of correlations to tell the thinking mind where to look next, or what to do next, if with reason, we are to put to use such correlations, for whatever value...1991 "Humans have the capacity to make magic but some have the capacity to make magic logically. Some can do it logically and others can do so illogically." 1993 Paradox evokes potential and simplicity. As an effect upon our minds, paradox as opportunity reduces the authoritarian justifications of linear logic, and enhances the appropriateness of understanding to experienced function. Paradox teaches us to value the unity beyond the thresholds of meaning to particular minds." 1994 There was an undercurrent of distress at the immensity of the task we have taken on sometimes expressed in our nervous excitement, and sometimes expressed in our very cautious respect for our work. Here is Jonas talking to Bill Moyers: "We are sitting here now hoping to communicate some ideas that might be useful and helpful to others, for what purpose? Where have these ideas come from? There is some force that is inexorable. Think what would happen if we were to realize the power of that force, and what we might be able to do with it if we were to try to discipline it, to engage it for a purpose." We kept asking if we had the right players, and who else should join us. Again Jonas reflecting on the whole being greater than the sum of the parts: "Those who are the cause, the initiators, are ploymerizers--creators of living forms. Midwives who bring forth the ascent of Man. We need to make conditions conducive and to create propitious times that they may perform their function. Catalysts become involved in many different fields of energy to influence a process, not to participate in a reaction, and who 27 Ion, Heather, prepared after VValeo meeting, Cleveland, June 2000 17 are not altered by the reaction, that they may go on. That they may catalyze new perceptions." In discussing the conversations we may create, and taking on the responsibility for making sure there are consequences to what is learned in those conversations, we may well benefit from one of Jonas's poems: "Sense of self, sense of others With compassion, empathy in symbiosis. Feeding while being fed, The state of love. Self-sufficiency in free living Organisms and individuals, species among species Co-exist but do not consume. Return to others The benefits we receive in our lives That those who follow May be blessed." When Jonas encouraged Tom and me to use the phrase "create an epidemic of health" in our 1995 publication, he did not view it as a possession, but that we were to propogate the idea as widely as possible, and would not, because he trusted us, ever constrain the dissemination of these ideas. And so to the final tension--the trusting of emergence, which is a whole new way of being as well as thinking. I share with you my favorite of his poems from 1983, his book Anatomy of Reality: "My sail is full but I do not see what fills it, Forces guide me as if I did not need a compass It is enough that I should yield. This is mysterious I cannot see the forces that act upon me From within and without. I cannot deny their existence. If I try, I suffer. If I surrender, I become filled with the joy of life. I can only yield. I can only move in the direction toward which I am drawn To a destination for which I have neither map nor compass. I have never been there before. As it is for me, so it is also for others." 18 Tipping an Epidemic of Health28 What if there were a health virus that could spread globally with the speed and virulence of an e-mail virus? What if, instead of infecting a computer’s hard drive, the health virus made its recipients healthier? What if, instead of relaying the virus to everyone in the computer’s address book, a health virus spread this health to one’s circle of acquaintances? Since half of the deaths in the United States are preventable by changes in personal behavior, a health virus would have a large and fertile population to infect and create new strains. Jonas Salk concluded that the most powerful way to improve our health would be to create an epidemic of health. Health would be contagious, spreading from person to person in an ever-increasing and self-reinforcing cascade. In the same manner as a disease-based epidemic, healthy activities and knowledge that are nascent in the environment would suddenly “tip” into an epidemic. At the tipping point, small changes can have a dramatic effect. As Salk said, “Only a few are needed to visualize and to initiate a process that would become selforganizing, self-propelling, and self-propagating, as is characteristic of evolutionary processes.”29 The Internet and the global connectivity it provides have created an environment in which massive, global changes can happen with startling speed. It is possible to employ these dynamics for the improvement of everyone’s health – to create an epidemic of health. From the perspective of those focused on the woes of our current health care system, this vision may seem to be simplistic. However, trying to fix our current system from within is like trying to get out of a hole by digging it deeper. The solution rests in climbing out of the hole by taking a fresh perspective. Considering the intrinsics of health, trends in computers and communications, and new understanding of the behavior of masses of people connecting together, an epidemic of some kind is inevitable. The question is, what will tip it, and will it truly improve our health? Why Do We Need an Epidemic of Health? Our current health care system is based on a notion of an industry that “produces” health care that is “consumed” by patients. This industrial model works for automobiles, steel, and coal industries, where each enterprise allocates scarce resources according to the laws of supply and demand. However, health is not a commodity subject to the laws of supply and demand. There is no central reservoir of health that is depleted when someone gets healthier. The opposite is true: those avoiding or curing themselves of tuberculosis or alcoholism improve everyone else’s health. Rather than pricing and allocating health as transactions in a marketplace, the epidemic of health would trigger a positive feedback loop in which 28 Prepared by Tom Munnecke under contract for the Business Enterprise Solutions and Technologies, Veterans Health Administration, Department of Veterans Affairs, May 2000 Munnecke, Tom, and Wood-Ion, Heather, “Creating an Epidemic of Health with the Internet,” US Medicine Magazine, Washington, DC August 1995. 29 19 everyone, acting in accordance to their own self-interest, could become healthier. In so doing, they would directly or indirectly improve everyone else’s health. This is a shift from traditional thinking: In spite of all the changes this last decade the health system still contains the characteristics of a heavy industry: the application of bureaucracy and technology to the production of care. Although the power relationships have changed dramatically throughout much of the Industrial era, the health system has been dominated by providers, insurers, employers, and governments. They had the information, they made the decisions, they had the power. Despite of the best intentions, it was the "Don't worry your pretty little head" era.30 Our current health care system is based on the notion of transactions – specific, predefined things that the health care provider does to a patient. A health care enterprise will be reimbursed for performing a coronary artery bypass procedure. However, dealing with the long term preventive activities that could avoid the need for the surgery are not easily expressed in terms of the transactional model. The epidemic of health deals with the notion of transformations – general, longterm changes that are driven by the self-interest of the individual. The role of the organization or enterprise is to facilitate these transformations, and the ultimate responsibility for the success of the transformation lies with the individual. Twelve-step addiction programs are an example of this. From a transactional perspective, because they are volunteer, non-profit organizations, they do not generate any revenues. An accountant adding up the transactions of all twelve-step organizations would conclude that they barely exist. From a transformational perspective, however, they succeed or fail based on their ability to transform the lives of their members. If their program works, and excites other members to join, the organization thrives. Their success is not measured with a chart of accounts of transactions, but rather their transformational success and the virulence of their message. Our health care system is based on “doing” rather than “being.” Physicians are trained to do things to patients. However, alternative behaviors may be more cost effective, even according to traditional transactional accounting techniques: “a patient's use of safety belts would receive less attention from the clinician than the results of a complete blood count (CBC) or a routine chest radiograph. A careful review of the data, however, suggests that different priorities are in order. Motor vehicle injuries affect nearly 3.5 million persons each year in the U.S.; they account for over 40,000 deaths each year. Proper use of safety belts can prevent 40-60% of motor vehicle injuries and deaths. In contrast, there is little evidence that performing routine CBCs or chest radiographs improves clinical outcome, and these procedures are associated with increased health care expenditures.”31 Lemieux, Jeff, “The Future of Health Care,” presented to the American Medical Association House of Delegates, San Diego, CA, December 6, 1999 http://www.dlcppi.org/texts/health/ama.htm 31 US Preventive Services Task Force, Guide to Clinical Preventive Services, Second Edition, http://vesalius.cpmc.columbia.edu/texts/gcps/gcps0006.html 30 20 Consider a physician who convinces a patient to wear a seatbelt, which saves their life some years later. There is no accounting activity to measure this success – the physician may not even know of the event. The patient may not even remember that their transformation to becoming a seatbelt-wearer was triggered as a result the physician’s suggestion. But the life-saving result was far better than any series of routine lab tests and X-rays. Somehow, the long-term transformational value of apparently simple activities has to be reckoned in the day-to-day decisions of the individual and the health care provider. A New Level of Connectivity Envisioning health as an epidemic of personal transformation is a radical departure from the current health care systems model. Rather than envisioning the system as a centrally controlled, top-down producer of health care, we need to envision imagine health as an interaction between millions of highly connected individuals. One of the effects of having a highly interconnected space is that things happen according to the dynamics of an epidemic: “Epidemics are a function of the people who transmit infectious agents, the infectious agent itself, and the environment in which the infectious agent is operating.”32 For an epidemic to tip, there needs to be a change in one or more of the abovementioned factors. People and our understanding of what constitutes health are generally stable entities. However, our communications environment has changed dramatically. The Internet, the World Wide Web, e-business, and electronic mail have created radically new conditions. This is the most fertile area to search for a trigger to the tipping process. The technology of computers and communication has been undergoing dramatic transition over the past decades. The transition from centralized, “clockwork” batch processing systems to today’s swarm of interaction on the Internet is instructive. Kelly describes this as the swarm effect: “We find many systems ordered as a patchwork of parallel operations, very much as in the neural network of a brain or in a colony of ants. Action in these systems proceeds in a messy cascade of interdependent events. Instead of the discrete ticks of cause and effect that run a clock, a thousand clock springs try to simultaneously run a system. Since there is no chain of command, the particular action of any single spring diffuses into the whole, making it easier for the sum of the whole to overwhelm the parts of the whole. What emerges from the collection is not a series of critical individual actions but a multitude of simultaneous actions whose collective pattern is far more important. This is the swarm model.”33 32 Gladwell, Malcolm, The Tipping Point, How Little Things Can Make a Big Difference, Little, Brown and Company, 2000, p. 18 33 Kelly, Kevin, Out of Control, The New Biology of Machines, Social Systems, and the Economic World, Addison Wesley, 1994, p. 22 21 Inverting the locus of control from the provider to the individual triggers many changes in the patient – physician relationship: “Whereas the clinician is often the key figure in the treatment of acute illnesses and injuries, the patient is the principal agent in primary prevention that addresses personal health practices. Therefore, one of the initial tasks of the clinician practicing primary prevention is shifting control to the patient. To achieve competence in the task of helping to empower patients and in counseling them to change health-related behaviors, many clinicians will need to develop new skills.”34 In the same way that the Internet revolution can create successful entrepreneurs or computer virus hackers, the connectivity created by the Internet can be a tremendous boon to society, or the source of danger and difficulty. Health and the Swarm Effect This swarm effect directly applies to our health. Plagues, epidemics, and the effects of disease have shaped our history. Our ability to deal with the effects of public health activities has been one of the greatest contributors to health in the 20th century: “Infectious diseases such as poliomyelitis, which once occurred in regular epidemic waves (over 18,300 cases in 1954), have become rare in the U.S. as a result of childhood immunization. Only three cases of paralytic poliomyelitis were reported in the U.S. in 1993, and none was due to endemic wild virus. Before rubella vaccine became available, rubella epidemics occurred regularly in the U.S. every 6-9 years; a 1964 pandemic resulted in over 12 million rubella infections, 11,000 fetal losses and about 20,000 infants born with congenital rubella syndrome. The incidence of rubella has decreased 99% since 1969, when the vaccine first became available. Similar trends have occurred with diphtheria, pertussis, and other once-common childhood infectious diseases. Preventive services for the early detection of disease have also been associated with substantial reductions in morbidity and mortality.”35 If we think the epidemic of health as a health virus to be spread at Internet-like speeds, we must consider the environment and infrastructure within which it must operate. Creating the conditions for the environment is a critical step to allow the epidemic to proceed. One of the most powerful positive feedback loops in the epidemic of health is that the “health virus” operates on the same individual as the one spreading it further. “Epidemics are, at their root, about the very process of transformation. When we are trying to make an idea or attitude or product tip, we’re trying to change our audience in some small yet critical respect: we’re trying to infect 34 US Preventive Services Task Force, Guide to Clinical Preventive Services, Second Edition, http://vesalius.cpmc.columbia.edu/texts/gcps/gcps0006.html 35 ibid 22 them, sweep them up in our epidemic, convert them from hostility to acceptance.”36 Factors Fueling an Epidemic There are several reasons to be optimistic about the prospects for an epidemic of health: 1. Much of health is “bits” instead of “atoms.” Knowledge, education, research, and communication about healthy behaviors can be communicated quickly and inexpensively over the Internet. 2. It is in everyone’s self-interest to become healthier. The momentum behind the epidemic could be personal interest, not requiring altruistic activities. 3. We already know much of what is required to be healthy. We do not need any scientific breakthroughs. While we can expect major developments and greater understanding of the health process, this is not a necessary condition for the process. 4. Approximately half of the deaths occurring in the US each year are preventable by changes in lifestyle37. Those who would benefit from healthy behavior are the ones who are most able to affect the transformation – the individuals themselves. The potential gain from the epidemic of health would have a huge impact on society, the economy, as well as our general health. 5. The emergence of the Internet and associated communications technologies provides unprecedented person-to-person connectivity – an essential component for the spread of an epidemic. More than just serving as an infrastructure, however, the Internet can serve as a role model for the epidemic. For example, the World Wide Web started as grand concept with just a few “seed” standards, from which it evolved into a global phenomenon. Good ideas spread rapidly, insuring that success was replicated. 6. Health is scaleable. Scalability, a concept driven home by Internet technology, means that a system can grow freely without hitting limiting constraints in the infrastructure that supports it. For example, if 1 million more people suddenly adopted healthier lifestyles, it would not inhibit 10 million more from doing the same. 7. Replicating success is built in. Those who have achieved health are generally enthusiastic about talking about it. “There is no missionary like a convert.” 8. Connectivity is increasing at an increasing rate. This accelerator effect means that the effects of connectivity will compound. The more health-related activities which connect via the Internet, the more it will attract new people. 9. The Internet is a fertile breeding ground for “underground” activities. The epidemic may emerge as a self-organizing “underground” activity outside of the traditional management or health care channels. In the same way that Amazon.com was an upstart from outside the traditional book-sellers community, 36 Gladwell, Malcolm, The Tipping Point, How Little Things Can Make a Big Difference, Little, Brown and Company, 2000, p. 89 37 Bloom, Barry R. “The Wrong Rights”, Newsweek Magazine, Oct. 11, 1999 23 the epidemic may occur unencumbered by the difficulties of the current health care system. 10. Health can be driven by the swarm effect. Everyone can get healthier in some way. This can be contagious, infecting others with the same attitudes and behaviors. This positive feedback loop can be used to drive the epidemic to everhigher levels of general health. 11. Improving health does not have to cost money. Getting people to wear seatbelts is a matter of education and communication, not an issue of allocating scarce resources. These factors are mutually reinforcing. Each one of them feeds the other, and in so doing, reinforces itself. This positive feedback loop is a requirement of epidemic-like expansion. The conditions are ripe for tipping an epidemic. Dampening Effects on the Epidemic. However, there are also factors that dampen the epidemic. 1. 2. 3. 4. 5. 6. 7. There is a time lag between action and response. Teenagers see immediate benefits of smoking, but not long-term effects until it is too late. Expensive but intervention for Type 1 diabetes on a 2 year old will save an even greater amount of expenses and health problems in 15 to 20 years. However, there is a very low probability that the health plan incurring expenses of the child will be the one that save the money decades later. Different feedback for different demographic groups. Elderly may see greater benefit from exercise (stronger bones, less falls) than young; mothers are particularly sensitive to education and training at the time of their first birth. There is no “one size fits all” message for the health virus. It must be tailored to the context of the individual, which will create many strains of the virus. Most people already know that their behavior is self-destructive, but continue it anyway. Smokers know that smoking is damaging their health; overweight people already know that losing weight would benefit them. Environmental effects drive unhealthy behavior. People with more income and less time will spend more money on fast food, for example. As the economy creates greater wealth, the level of obesity has increased. Current management and control model. Systems which are managed and controlled by traditional “clockwork” approaches, are easily overwhelmed by positive feedback loops. Like a public address system in which speakers too near the microphone create an overwhelming squeal, a health care system which is based on centrally controlled, “clockwork” management could easily be overwhelmed by “swarm” dynamics. Not all of health is representable by bits of information. For example, getting vaccines to children in need is not just a matter of communication of bits of information or changing behavior. Vaccines are a commodity, and do require “hard” resources to deliver. There is no guarantee that an epidemic would tip towards improved health. For example, an enthusiastic person could claim that they cured their cancer by burying a potato under the full moon and energetically announce this “cure” in Internet newsgroups and web sites. This message could be picked up 24 and amplified by other groups. Sometime later, someone searching for a cure for cancer on the Internet could find a tremendous number of “independent” confirmations that burying potatoes in the full moon can cure cancer. There must be a means of injecting science, evidence, and trust in order to insure that the epidemic tips towards health. An Example of a Social Epidemic: Creating an Epidemic of Learning The creator of the Sesame Street television series Joan Gantz Cooney wanted to use the television medium to address the problem of literacy for three-, four-, and fiveyear old children: Her agent of infection was television, and the “virus” she wanted to spread was literacy. The show would last an hour and run five days a week, and the hope was that if an hour was contagious enough it could serve as an educational tipping point: giving children from disadvantaged homes a leg up once they began elementary school, spreading prolearning values from watchers to nonwatchers, infecting children and their parents, and lingering long enough to have an impact well after the children stopped watching the show.38 Sesame Street has been subject to more academic scrutiny than any television show in history – it has been proved to increase the reading and learning skills of its viewers. And the effects of this literacy have spread beyond just the watchers: “There are few educators and child psychologists who don’t believe that the show managed to spread its infectious message well beyond the homes of those who watched the show regularly.”39 This learning epidemic cascades to affect our health in many other ways: “There is no more vulnerable population in this country than people who don’t read. This group has the worst health, the least knowledge of healthpromoting behaviors, and the fewest socio-economic resources to deal with those problems… our preliminary analysis shows that patients with inadequate literacy skills have a 50% increased risk of hospitalization, compared with patients who had adequate literacy skills…we can only speculate on the causes of excessive hospitalizations in this vulnerable population. Less knowledge of self-care options, worse general health behaviors, and less ability to negotiate today’s complex healthcare system may all be major factors in the equation… About 36 million people are eligible for Medicare in the United States…16 million [of the elderly] are functionally illiterate. The average hospitalization cost per person per year for Medicare patients is $2,262…one might assume that a 25% to 50% increase in the cost of hospitalizations for Medicare patients with inadequate literacy skills. If we accept these assumptions, 38 Gladwell, Malcolm, The Tipping Point, How Little Things Can Make a Big Difference, Little, Brown and Company, 2000, p. 89 39 Gladwell, p. 91 25 increased hospitalization costs directly attributable to inadequate health literacy could total $8 to $15 billion per year.”40 Baker, David W. “The Impact of Health Literacy on Patient’s Overall Health and Their Use of Healthcare Services,” in the Proceedings of “Health Literacy, A National Conference”, June 1997, sponsored by Center for Health Care Strategies, Inc. 40 26 Steps Toward an Epidemic of Health41 “The patient is the center of the health care universe, not the hospital…This will require a paradigm shift in how we view our technology in the future.”42 Jonas Salk spent much of his latter years thinking about how to solve the problems of health, concluding that we needed a paradigm shift to create an "epidemic of health." This represents a fundamentally new approach to the notion of maintaining and spreading health in modern society. The rapid acceptance and growth of the Internet is creating a new environment within which entirely new dynamics operate. Industry after industry is discovering that the old ways of interaction and control are obsolete in the frenzied pace of today’s Internet-driven environment. Some of these major changes are: 1. Personalization. Successful Internet activities are personalized to the individual’s needs. 2. Evolutionary growth. New systems and businesses emerge in an evolutionary manner from their predecessors. And, just like evolution, the exact nature of what emerges is unpredictable. 3. “Internet Time.” Things happen quickly on the Internet. Traditional concepts of 5year strategic plans are rarely applicable to Internet-based activities. 4. Control. A central authority does not control the Internet. The success of a web site is determined by whether or not people pay attention to it. 5. Overcoming time, distance, political, and geographical barriers. The Internet is making the world smaller in nearly every way. 6. The law of increasing returns. In the same way that someone else’s purchase of a fax machine made your fax machine more valuable, the fact that others are moving their information and services to the Internet make it more valuable for those already on line. These forces can transform an industry quickly. For example, on-line trading has taken over much of Wall Street largely outside the control or influence of the established broker networks. Upstart “attacker” companies used the Internet to introduce new approaches to trading based on the dynamics of the web. Older firms were required to move to on-line trading due to this competitive threat. The forces of the Internet can trigger massive changes in an industry, whether the industry wants it or not. In a similar manner, the Internet can be used to transform the process of health throughout the world. The question becomes, how do we insure that this transformation serves to increase our health? Unless the proper initial conditions are set, it is not clear 41 Munnecke, Tom, Prepared under contract for Business Enterprise Solutions and Technologies. Chief Information Office, Veterans Health Administration, Department of Veterans Affairs, July 1999 42 VA Undersecretary for Health Kenneth Kizer, May 1997 27 that the transformation will drive increased health. If not carefully tended, this transformation could spiral in a negative way, serving to increase profitability of the health care industry at the expense of the health of consumers. Many factors can drive the epidemic in a positive direction: 1. People want to get healthier. This is a nearly universal goal of the population. Although the meaning of health varies with the context of the individual, the overall goal is very similar. 2. It is possible for everyone to get healthier. Health is not a zero-sum game, where one person’s increase in health creates a corresponding decrease in someone else. Health, in fact, can be propagated according the law of increasing returns: the greater the degree of healthy interaction. 3. Health is mutual. As the old saying goes, “Those who teach learn twice.” There is a mutual relationship between the teacher and the student. Those in support groups who help others can find that they are also helping themselves. As we have seen in various support groups, there is great benefit to sharing experiences and support between peer groups. Many health processes can be structured so that they are driven by a sense of mutuality. 4. Much of health is information. Information, and our ability to communicate and understand it, is an essential factor in much of the health process. From the discovery of antibiotics from bread mold, to the notion that exercise instead of bed rest can be good for cardiac patients, dramatic changes in our health have come from understanding information. Acquiring this information can be an expensive process. Distributing this information, once it has been reduced to a bitstream can be accomplished at very low cost. 5. Technology is providing low cost communication. The Internet and emerging communications technologies are providing low cost, highly accessible information. The convergence of the Internet and the set-top television box creates an even larger within which the epidemic can occur. 6. Success can be replicated. Driven by the principles of mutuality, successful activities will propagate throughout the relevant communities. Success is defined in the context of the individual or community of interest. 7. Health is universal. Everyone is involved in health, whether they chose to be or not. This provides a very large space in which the epidemic can proceed. 8. Health is a bottom-up phenomenon. In contrast to the top-down health care industry (health care flows from providers to consumers), the health epidemic can be largely driven by the energies and motivations of the individual. 9. The epidemic is on the verge of triggering. The density of the mousetraps in the health space is rapidly increasing. This is a fundamentally new aspect of human behavior. Never have so many people been interconnected in so many ways independent of time and distance. The Role of the Commons. Rather than think speak of health as an industry, driven by market forces, it is instructive to think of health as a public commons, something which is available for all, and increasing in value to all. This is a practical notion: someone else successfully 28 Development fighting off an infection decreases my chances of getting that infection. The healthier my community becomes, the healthier each of us become. This upward spiral of increasing health can be driven by the law of increasing returns – everyone becoming healthier triggers everyone to become even healthier. The commons effect can be seen in real estate. For example, Central Park in New York is one of the most expensive pieces of land in the world. It could be sold to make room for skyscrapers, which would solve many of the city’s budget problems. Instead of paying for the maintenance of the commons, it could be a source of revenue to the city. Despite these market forces, Central Park thrives as a commons for New York City. If would be impossible to imagine buying a square mile of Manhattan to make it into a park today, however. The window of opportunity has passed. The city will keep the park, already established, as an intrinsic part of its community. However, it could never afford to create it anew. Too Early Window of Opportunity Too Late Time Figure 1 Timeline of the Development of a Commons There was a time in the development of Manhattan during which it was too undeveloped to have a park, a time when it was feasible to establish a park, and a time when it was impossibly expensive. Each of these stages is irreversible, and once the window of opportunity has passed, it is forever closed. This can be seen in figure 1, “Timeline of the Development of a Commons.” In a similar way, the commons effect for the epidemic of health will have a major impact on the future of e-Health. Will we have the foresight to create appropriate commons for the good of all? Or will e-health develop as the equivalent of so many strip malls and skyscrapers, devoid of sense of common good? 29 The Health Commons One of the essential commons for the epidemic is science and evidence based medicine. There is a vast knowledge and research base in medicine and health, largely funded through public and philanthropic funds. This is one type of information which belongs in the health commons. Harold Varmus, director of the National Institutes of Health is proposing a system for communicating scientific information electronically: 43 Electronic communication is making dramatic changes in the way information is exchanged among scientists, including biomedical scientists. Over the past decade, steeply increasing numbers of scientists on all continents have abandoned traditional mail and faxes in favor of electronic mail. Many log-on to GenBank and many other data repositories on a nearly daily basis. The titles and abstracts of papers published in most scientific journals are available "on line" from the date of publication and sometimes even before; some full texts can be accessed electronically and downloaded, with or without subscription fees; and convenient, freely accessible resources, such as PubMed (http://www.ncbi.nlm.nih.gov/PubMed/), provide powerful engines for searching the biomedical literature. In at least one field, physics, preprints are made freely available electronically to interested readers, through a server called "e-print" (http://xxx.lanl.gov). In other fields, including biology, many laboratories maintain World Wide Web pages that offer their colleagues deeper views of the data that support published findings, describe methods in detail, illustrate the most recent talks given by lab members, and serve as important sources of specialized information and links to other Web sites and citations. Despite these welcome and transforming changes, the full potential of electronic communication has yet to be realized. The scientific community has made only sparing use thus far of the Internet as a means to publish scientific work and to distribute it widely and without significant barriers to access. Informative and even visionary essays have explored this topic (see, for example, articles by Ginsparg [http://xxx.lanl.gov/blurb/pg96unesco.html], Walker [http://www.amsci.org/amsci/articles/98articles/Walker.html], and Harnad [http://www.princeton.edu/~harnad/nature.html], and references cited therein, as well as other recent proposals [http://library.caltech.edu/publications/scholarsforum and http://www.arl.org/newsltr/202/intro.html]). In this essay, we propose a system for electronic publication of new results and ideas in the biomedical sciences. We do this with the conviction that such means of publication can accelerate the dissemination of information, enrich the reading experience, deepen discussions among scientists, reduce frustrations with traditional mechanisms for publication, and save substantial sums of public and private money. These views have proven controversial. The window of opportunity for a commons in scientific communication is already closing: Journals which charge libraries $15,000 per year are not extremely concerned with the notion of publishing scientific information over the web. An analogy to this process would be for a commercial interest 43 http://www.nih.gov/welcome/director/ebiomed/ebi.htm 30 to purchase a strip of land 6 inches wide around a National Park, so that they can charge a toll for everyone who crosses their property. The firm is not creating value, but rather assessing a toll on a commons held in the public interest. In the same way, health information funded by public funds should be held in a health commons, and not subject to a toll by squatters claiming the right to a toll for access. The Web as a Commons One way to look at the World Wide Web is to see it as a global commons for information. As such, it is an evolutionary structure, growing from simple initial conditions towards ever-increasing complex as it adapts. Simultaneously, the public’s understanding and use of the web is evolving, creating a coevolutionary spiral between the technology and the people using it. The web can be understood easily as an evolutionary outgrowth of a few very simple ideas: 1. A minimal set of initial conditions: URL, HTTP, and HTML standards describing naming, transport, and formatting aspects of the web. 2. A set of constraints. All web pages are accessible via the IP communications protocol. 3. An evolutionary “fitness function” defining what types of web pages would succeed. This function is “attention,” those sites to which attention is paid thrive, those which are ignored, die off. These dynamics can be illustrated as follows: consumer attention drives evolution Innovative structures emerge s tra int Co ns Amazon.com s int tra ns Co Time e-Bay Yahoo! Initial Conditions Web information is constrained to Internet Protocol Minimal initial conditions include URL, HTTP, HTML Figure 1 Evolution of the Web 31 The web began in 1989 as a modest technology, consisting of simple standards for naming web pages (URL), a protocol for exchanging web information (HTTP), and a language for formatting pages and making links between them (HTML). It defined constraints on the system, namely that all information had to be accessible via the Internet Protocol (TCP/IP). There were a large number of competitors at the time who had their own proprietary protocols: Compuserve, AOL, Genie, Prodigy, and others. Each of them would have preferred to have their proprietary networks the foundation of the web. Had this been the case, the web would have been controlled by a single company, which would have defeated the web’s philosophy of openness. It would not have been a commons. A third factor, consumer attention, was the key that drove the web in the open standard. People did not want to open an account and sign on to Compuserve for one kind of information, and do the same for AOL for other information. Once it became apparent that it was possible for information to be shared globally with just the click of a mouse, then the barriers to the global information commons became glaringly obvious. Users simply wanted to get the information, and producers of information came to be valued according to their “eyeball” count – the number of people who viewed their sites. Only the exceptional information provider could succeed by putting up a barrier between their site and the public. If they do anything to discourage “eyeballs,” some competitor would offer the information for free. Connect to Compete This “connect to compete” model rewards those who connect best with their customers. The web provided a commons, an infrastructure upon which a new form of competition has arisen. The web is not in a controlling position in all of this, but rather has created an environment in which this behavior is rewarded. Consumer attention has become a commodity, and those companies who have mastered this notion are the ones who are thriving in today’s information economy. It is instructive to note what the web is not. The web was not created by authoritative committees deciding how to organize global information. The were no preallocated ranges of numbers, dedicated to specific disciplines (web sites 1-100,000 for physics, 100,001 to 200,000 for chemistry, etc.) The web was simply a chaotic mix of information, which could be communicated and linked according to however the world wanted to access it. Structure and order within the web were emergent properties which evolved according to the dynamics of “connect to compete” and consumer attention. These structures and this order were not predefined. Although it is has become a household word today, in its infancy the web was a very difficult thing to explain to people. After Tim Berners-Lee, who invented the web at CERN laboratories in Switzerland, he needed to populate it with some information. He connected it to the CERN phone directory. The reaction to these people was, “why go through all this just to read our phone directory?” They did not yet see the value of interconnecting everything in a global information commons. It would take several more years for the system to gain critical mass. From the perspective of someone just looking at the first web application, it would have been hard to imagine the avalanche of events which would occur in the next decade. How could a simple open standard in which no one had a financial interest 32 overthrow the powerful proprietary networks of the day? How could there be sufficient interest to make people spend millions of dollars putting the information on the web without a clear financial payback? Who would ever be able to find anything in this chaotic mess? Who would manage and control this system, and who would pay for this control? How will there ever be anything useful on the web, instead of just being an academic exercise? With the benefit of hindsight, these questions seem silly now. The web created a new model for organization and complexity management. The key to the web’s success was 1. Simple initial conditions 2. Minimal constraints 3. A fitness function which controlled the evolution of the system. Applying Lessons Learned from the Web to the Epidemic of Health The epidemic of health can be viewed as a recapitulation of the web experience, applied to the context of health. From the minimal set of initial conditions and constraints, create an environment in which entities which contributed to health thrived. This is illustrated below. The initial conditions for the epidemic are created, as well as the constraints within which the epidemic will be contained. Activities and entities that improve an individual’s health thrive in this environment. Note the absence of authority and centralization. There are no preallocated resources dedicated to specific activities. There are a variety of powerful proprietary interests outside the epidemic, just as there were a variety of proprietary networks outside of the web. The dynamics of personalization, equivalent to the concept of attention in the web, drive the evolution of the system. Those who seek to understand systems based on hierarchical control structures will have a difficult time understanding the dynamics of the epidemic of health. It will appear that the initial conditions are too weak, control too dispersed, and existing interests are too strong to make a difference. Any application of the principles, taken in isolation without a critical mass, like the CERN phone directory application, will appear to insufficient for driving the epidemic. It is only when an “avalanche” of activities occurs that the full understanding of the epidemic will be understood. At this point, the personalization process becomes the driver. Those who contribute to individual’s health, as perceived by those individuals, will be the ones who thrive in this environment. 33 Things which increase individual's health thrive Innovative health structures emerge tra int s ns Co ??? s Co ns int tra Time ??? ??? Constraints define limits of behavior Initial Conditions Minimal initial conditions include Internet, personal space, trust, mutuality Figure 2 Evolutionary view of the Epidemic of Health 34 Ensembles and Transformations44 This paper introduces two conceptual building blocks as a foundation for thinking about a self-organizing approach to health: 1. The transformation, which represents a flow of multidimensional, purposeful interactions. 2. The ensemble, which represents a trusted community within which transformations may occur. The Concept of the Ensemble The ensemble is a space within which the health process occurs. It is a community of people, information, and associations that interact in a loosely coupled manner. The ensemble provides a community for discourse within which emergent properties may flourish. Ensembles are scalable, which means that they could be as small as to deal with a specific issue for a specific person, or deal with millions of people. They can be viewed from a fractal perspective.45 Each ensemble has a community, which is generally known to all participants. The knowledge of this community allows participants to define and understand their own radius of trust. An ensemble is a space for discourse. Communications occur within the ensemble within a given context. This context defines the openness or closure of the community of interest. Each ensemble has its own identity, and is able to associate with an arbitrary number of other ensembles. Shared meaning within an ensemble is derived from the relationships and context of the ensemble. Kenneth Gergen discusses the role of discourse and the concepts of social constructionism: “The meaning of utterances is generated in a dialogic relationship. There is no meaning that is not derived from relationship itself…we find that the ability of the individual to mean anything – to be rational or sensible – is owing to relationship. The self cannot in this sense be separated from the other. Self and other are locked together in the generation of meaning…to be means to communicate.”46 In his vision, the self is inextricably woven into relationship. The ensemble serves a focal point for this “selfness.” Once this is defined, ensembles are free to weave themselves into new relationships. Some examples of ensembles are: 44 Munnecke, Tom.

They provide a place for holding state information for the transformation. The Emergence of Self-Organization “In the early 1990s, you had to travel in fairly esoteric circles to hear about self-organizing systems. The notion wasn't on the lips of practical businesspeople. It was the sort of idea that percolated far outside the mainstream, at think tanks such as the Santa Fe Institute. Today, self-organization is rapidly becoming a very hot idea, the essence of which is that top-down master plans aren't the only way to build something big and lasting. Unorganized assemblies of people can create everything from marketplaces to computer systems almost spontaneously, on the fly, from the bottom up.47” We find evidence of self-organization everywhere throughout nature. A cut finger heals itself, the body maintains homeostasis, and predator/prey populations adjust themselves to their environment. We also find self-organization in man-made systems, such as the World Wide Web and many of the companies it has triggered. One of the greatest threats to Microsoft’s dominance in the software market comes from a selforganizing group of programmers creating the Linux operating system. 47 Bernard Wsocki, Jr., Wall St. Journal, July 10, 2000 36 It is intriguing to consider how self-organization may be used in the field of health and health care. However, this forces us to address two questions: 1. What is the “self” which does the organizing? What is the entity that properly serves as the core around which health organizes? 2. What is the scale at which this self-organization takes place? Is it the individual, the family, the nation, the world? Traditionally, we have focused attention on the interaction between the health care provider and the patient, and we have measured this interaction in the form of transactions. This orientation, however, does not deal well with other forms of interaction such as family, community, self-help groups, or other forms of health assistance. For example, someone who benefits from attending Alcoholics Anonymous generates no transactions to be measured. AA is a self-organizing group that benefits many people around the world, yet it is “invisible” to the world of transaction processing. There is no single “self” which should drive self-organization in health, nor is there a single scale which can be exclusively used. We must envision an approach that deals with an arbitrarily large number of “selves,” which range from an issue involving a single individual to large aggregations of people. The Concept of the Transformation A goal of an ensemble is a transformation – a purposeful flow of activities and information. Transformations may be contrasted against the notion of a transaction. A transaction measures interaction as a snapshot in time. It measures the interaction according to predefined categorizations, such as the chart of accounts or DRG coding schemes. These measurements are then aggregated hierarchically as a way of understanding the overall operation of the system. This aggregation is then used to reconstruct the flows of activities within the system. Transactions and transactional thinking are ubiquitous in modern society. This works very well for certain classes of activities. We can insert a card into an ATM and get cash with ease and accuracy. The computing industry supports transaction processing software, transaction monitors, and databases to hold transactions. However, it is not always possible to apply transactional technology to complex problems such as health. Interactions are transactionalized in one context, then analyzed in the context of the aggregate. Furthermore, the context of the individual gets lost in the aggregation. The interaction can have many dimensions, whereas the transaction only measures one of them. A transformation deals with the longer-term flow of activities in the context of the individual. It sees the river as a flow, not a series of snapshots. Transformations occur in a context specific to the community within which they occur. An example of transformational thinking in a clinical setting is: “What takes place as the patient and the physician interact….? One exchange is that of perceptions of reality, what each knows about the problem. Another exchange is that of trust: the physician trusts that the patient both wants to change or solve the problem and is willing to take 37 action to do so; the patient trusts that physician has the appropriate skills to repair damage or advise on the changes necessary to resolution. These are the interactions of healing, older than Hippocrates and consistent still wherever healing is practiced. The exchange is transformative in nature, not transactional. The patient, and hopefully, the physician both learn and become different consequent to the interaction. Commerce, the purchase of products, is transactional – neither side of the interaction changes in function or ability to function.”48 Transformations are based on an ongoing exchange of information and relationship. This means communicating in the form of a dialog rather than a monolog. The ensemble provides the space within which this can occur. “We often speak of dialogs not just as conversations in general, but as special kinds of relationships in which change, growth, and new understanding are fostered. About this sense of dialog almost nothing has been said… This is the challenge of dialog as a transformative medium. We are not speaking here of a mere exchange of views, but of moving beyond alienated coexistence to a more promising way of going on together.”49 Summary of Transformations The properties of a transformation are: - They are process oriented They are multidimensional – there is not necessarily a single metric by which to define goodness or improvement They take place within a the context of a specific community They are purposeful – leading to a direction which is deemed to be an improvement They are stateful – based on past interactions Improvements are directed internally, rather than imposed externally. They have their own arrow of time. Transformations cannot necessarily be “replayed” to have the same effect. They are non-linear. We cannot necessarily add up transactions to get an aggregated measure. Ensembles as Therapeutic Spaces As an example of the transformational value of an ensemble, consider the following comment by a member of a support group for those severely depressed: “To pretty much sum up my own experience with this medium, I feel that it is absolutely invaluable. The last year…has been, to put it mildly, the low point in my (and my family’s) life…I no longer sleep a full night…this message Ion, Heather Wood, “Ethical Dilemmas in Managed Care”, in Ott, et al, Managed Care and the Cardiac Patient, Hanley & Belfus, Philadelphia, 1993, p. 118 49 Gergen, Kenneth, Invitation to Social Constructionism, Sage Publications, 1999, p. 148 48 38 board has been my rock, as it is always available to me, and people are checking in on a daily basis. It is enough to know that you are never alone in the battle and there is always another person (or twelve!) there to help you through rough times.”50 There are several lessons that are illustrated in this example: The value of community The role of trust The value of dialog The manner in which the community establishes shared meaning through dialog The role of connectivity The role of relationship and association with peers The generative nature of the community The fact that it is asynchronous – things happen when they happen, not according to a predefined schedule The importance of context Emergent properties Transformative dialog There is always someone there to talk to; the patient feels comfortable with the group There is sufficient trust developed within the group to allow them to talk about depression and the problems of suicide The method of communication is based on interaction between participants, not a monolog from an authority The group develops their own narratives and stories, creating their own culture and language. The group is available day or night, from anywhere in the world using an infrastructure that is already in place with the Internet. The group allows them to associate with others who share similar problems, some of whom have worked through them, some of who are learning from others. Positive feedback drives the community People can come and go on their own schedule and needs. The community and its culture create a context within which the group can proceed. The whole of the group is greater than the sum of the participants. People sharing similar problems and goals are able to transform themselves, both individually and as a group. If a computer replayed the dialog back to someone outside the community, it would be a monologue. Passive listeners would not know the context of the conversation, nor would they feel part of the community. They would not know who the 50 Gergen, Kenneth, Invitation to Social Constructionism, Sage Publications, 1999, p. 213 39 participants were, what levels of trust they could ascribe to the speakers. They would not be able to ask questions to clarify issues. In short, the shared meaning that was created in the original ensemble was an emergent property of the interaction within the ensemble. Merely playing back a transcript of the conversation is not a substitute for actually experiencing the dialogue. Thus, the value of this interaction is in relationship and the context. There is an “arrow of time” to the transformation and dialog. We cannot simply reverse the clock and go back to the same state. People cannot “unsay” things, and knowledge, once communicated, cannot simply be erased. Ensembles and Transformations affecting the Clinical Process Dr. Larry Weed, inventor of the problem-oriented medical record that is taught throughout medical schools today, discusses an interview with a hospital patient about to be discharged. Dr. Weed: Do you have a copy of your own medical record?” Patient: “No.” Dr. Weed: Are all your medications in the bedside stand, and does the nurse come around at regular intervals to see if you are taking the right ones at the right time?” Patient: “No. The nurse just comes with little paper cups with pills in them, and I swallow whatever is there.” Dr. Weed: “Do you know what a flowsheet is? What parameters are we trying to follow? What endpoints we are trying to reach?” Patient: “No.” (At this point, Dr. Weed met with the medical staff to relate what he had found): Staff: “We never give patients their records.” Staff: “We do not have the time to give the medicines that way. It would not be safe to leave her with them unattended. She is on many powerful drugs. Staff: “The patient is not very well educated, and I do not think she could do all the things your questions imply.” Dr. Weed: “But, she is going home this afternoon. She lives alone. At 2PM you will put her in a wheelchair, give her a paper bag full of drugs, and send her out the door. Are you going home with her?” Staff: “No. Is her management at home our problem?” Dr. Weed: “You just said she could not handle it. Who will do it? The patient may not seem well educated or very bright to you, but what could be more unintelligent that what your are doing?”51 If the staff and patient in this example were part of an ensemble with a transformational goal, much of the discontinuity and isolation expressed might not have occurred. Perhaps there might have been a buddy system, where the patient could buddy 51 Weed, Lawrance, Knowledge Coupling, New Premises and New Tools for Medical Care and Education, Springer-Verlag, 1991, p. 13 40 up with someone else who had a similar recovery process. Perhaps the staff could have come up with creative ways of communicating the medication process to the patient. Ensembles Supporting Collaborative Spaces Creating a shared space within which collaboration can occur is a necessary step if health is to become a collaborative process. “Our goal must be to develop a system of medical care whereby all individuals are nurturers of their own health care and have available to them the guidance of an information system and the skills of providers who have demonstrated competence in performing specific tasks that patients who cannot perform for themselves. Until such a framework is in place and the patient is in charge, our situation can only grow worse.”52 “We must consider the whole information system and not just infinitely elaborate on the parts that interest us or fit into a given specialty. Patients do not specialize, and they or their families are in charge of all the relevant variables 24 hours a day, every day. They must be given the right tools to work with…After all, They are highly motivated, and if they are not, nothing works in the long run anyway, They do not charge. They even pay for help. There is at least one “caregiver” for every member of the population.”53 The ensemble provides a “home base” for relationships and associations, as well as their current and historical states. The ensemble is not just a medical record of the transactions that have occurred to a given patient. It is a collaborative space that provides an electronic means of dialog: “The real value in the sciences, the arts, commerce, and indeed, one’s personal and professional lives, comes largely from the process of collaboration. What’s more, the quality and quantity of meaningful collaboration often depends upon the tools used to create it.”54 MailMan Support of Ensembles and Transformations The MailMan electronic communications system55 was an integral part of the VA’s Decentralized Hospital Computer Program (DHCP) and DoD’ Composite Health Care System (CHCS) in the 1980’s. Although only one of many modules installed, it 52 Weed, Lawrance, Knowledge Coupling, New Premises and New Tools for Medical Care and Education, Springer-Verlag, 1991, p. 19 53 Weed, p. 13 54 Schrage, Michael, No More Teams!, Mastering the Dynamics of Creative Collaboration, Doubleday, 1990, p. 27 55 The author of this paper designed and wrote the original MailMan system in 1983. 41 was the most actively used program on both systems, sometimes accounting for 25% of the total usage. MailMan was designed to be more than just an electronic mail system. Its basic messaging structure was built around the notion of a dialog within a community. Each member of the community could see who else was participating, how much of the dialog they had read, and when they had last used MailMan (as an indicator of how active they were in the group). New messages were appended to the existing text as a continuous dialog, and each time a reader rejoined the dialog, they would be presented with the earliest unread portion of the dialog. There were simple forms of privacy and control, defining who could include other recipients, and allowing participants to terminate from future participation in the dialog. The approach differed from traditional electronic mail in several ways: 1. Each message had a well-defined (and visible to all participants) community of interest. The context for the discourse was within a known radius of trust. This is different from an Internet news group, for example, in which those posting the message do not know the identity or size of the recipient group. Talking in a closed message with 3 close friends is a different context than participating in a group of 3,000 in an open dialog. 2. Newcomers to the dialog were able to “catch up” with the history of the conversation, being able to read the thread from the beginning. 3. Replies were collated within the dialog so that if there were multiple responses to the dialog since the reader last participated, they appearrf as a single message (an notification) to be read as a thread. Traditional electronic mail systems can generate an exploding array of replies. For example, if someone sends a message to 20 people, and they all reply, there will be 19 independent messages. Some of these messages may have been made to the whole group (using the “reply all”), or just a private response from the individual. Reconstructing who has said what, and to what group, is a tedious process. Traditional mail systems do not maintain this state information. One could view MailMan as creating an ensemble around a topic. The ensemble is the set of recipients of the message, and the sense of community it creates. The dialog is the set of replies and interaction of the participants. The way that MailMan creates a sense of community by tracking the state of the message is an example of how a computer can be used to track the state of a transformation. These concepts are difficult to communicate to those have not used MailMan. If they have only used “stateless” electronic mail with no sense of community, they will not immediately appreciate the role of a dialog manager within a known community. Applications of Ensembles and Transformational Thinking Ensembles and transformations can be applied to many areas within the VA as well as other organizations. Some applications might be: 42 1. As a technology for Health e-Vet project. The approach to managing privacy and trust in Health e-Vet could be made applicable to ensembles in general, beyond just the personal health record. 2. The approach could be used to add a collaborative space concept to Health e-Vet, forming communities of interest and associations within the context of the personal health record. 3. Ensembles could be applied to the GCPR effort, allowing collaboration, communication, and dialog across loosely associated record systems. 4. The approach could be used to provide an “associative layer” which resides on top of existing web-based clinical applications. This would allow ensembles to form in the context of specific clinical information. This might appear to be a “sticky note” to the users. For example, a radiologist could attach an electronic sticky note to an image, and include a number of others in the discussion. A pathologist could contribute lab results interpretation, and the group could discuss the issue as an ensemble, using a threaded dialog manager. Each member of the ensemble could see who had seen what information; the dialog manager would track each member’s current status in the dialog. Participants would see a familiar yellow sticky note on clinical information; the technology underlying all of this would transparent to them. The information brought together by the sticky note is not necessarily integrated but rather associated as appropriate to the context. 5. Ensembles provide a formal context for defining ownership and access to information. Health information policy makers would have a finer granularity and context within which to discuss ownership of information (and information about information) than just the transactional model prevalent today. 6. Ensembles provide a platform for innovations in patient safety, education, access to knowledge bases, and support groups. 7. Ensembles provide a foundation for introducing transformational thinking to the VA. For example, clinical guidelines could be communicated within the context of a transformation, and their application could be managed by software (not unlike the dialog manager used in the “sticky note” concept above). 8. To serve as a platform for the Appreciative Inquiry (AI) conversations which are under discussion in Vvaleo workgroup 2. The ensemble provides a natural community of interest for discovering the positive core values that are part of the AI technique. 9. The AI technique of generating positive discourse could be made scaleable to reach a larger group of smaller ensembles. 43 Health and Positive Discourse56 Communication – what we say and how we say it – directly affects our health. According to a Mayo Clinic study, “People who expect misfortune and who only see the darker side of life don't live as long as those with a more optimistic view of their circumstances, a new study indicates. Researchers, comparing results from a personality test taken by participants more than 30 years ago with their subsequent mortality rates, found that people who scored high on the pessimistic end of the scale had a 19 percent greater risk of dying than people who scored high on the optimistic side.”57 “The manner in which people attempt to understand or explain the causes of stressful or adverse life events – particularly the use of a pessimistic explanatory style – can significantly undermine their psychologic and physiologic functioning, or adversely affect the course of an illness”58 If someone invented a pill that could reduce mortality by 19%, it would be heralded as a miracle drug. Simply changing the form of discourse from “pessimistic explanatory style” to “positive discourse” can improve our health. Is there some way that we can use modern communication technology to become have a population-wide health impact? Today’s technology gives us new ways to communicate across time or space, with anonymity or global public exposure, and make access to information and knowledge more egalitarian than ever before. We can form communities, exchange success stories and discover serendipitous relationships in ways unthinkable a decade ago. These communities are shaped by their participants, their organization, and the metaphors with which they view themselves. If these metaphors are deficit-based, then the community will evolve to fight against these deficits. If these metaphors are positive, then the community will focus on improving its strengths. 56 Munnecke, Tom, Prepared for Business Enterprise Solutions and Technologies.

So is the impact of cynicism and pessimism. Leaders who whine and blame engender those same behaviors among their colleagues. I am not talking about stoically accepting organizational stupidity and performance incompetence with a "what, me worry?" smile. I am talking about a gung-ho attitude that says "we can change things here, we can achieve awesome goals, we can be the best." Spare me the grim litany of the "realist," give me the unrealistic aspirations of the optimist any day. Gen. Colin Powell The difference between negative and positive discourse is more than just looking at a glass being half full or half empty. Each form of discourse has a self-reinforcing quality about it. Those looking for problems will find more problems the deeper they probe. Similarly, those looking for strengths will find more strengths the deeper they probe. Asking a question can create what it is questioning. Not Visible from "Full" Perspective Not Visible from "Empty" Perspective "Empty" "Full" Half Full is equivalent to Half Empty The above diagram illustrates the fallacy of assuming that a glass “half empty” and “half full” are equivalent perceptions. It is only in a limited range of discourse, the overlapping sections of the ovals, in which the two are equivalent. This overlapping area assumes that the system is linear – there is a fixed size glass, it is filled with an incompressible liquid, and that we the formula for fullness is equal to emptiness minus the amount in the glass. However, if we move outside the overlapping region into the rest of the “full” perspective, these assumptions break down. It is as if the glass itself gets larger as it fills up. The glass gets larger faster than it is “filled,” creating a self-propelling feedback loop that is not visible from the “emptiness” perspective. Similarly, the “empty” region outside the overlapping region has the effect of making the glass smaller as the glass empties. Dealing exclusively with the “empty” perspective eventually leads to a sense of futility that it requires an ever-increasing effort to maintain an ever-decreasing 45 effectiveness. The intensity of this negative feedback loop makes the benefits of the positive feedback loop difficult to appreciate. If we substitute the “empty” side with “negative discourse” and “full” side with “positive discourse” we can understand how this analogy can be used for thinking about organizations and systems. Optimism and positive discourse have generative qualities that feed on themselves. Appreciative Inquiry David Cooperrider of Case Western Reserve University developed the concept of Appreciative Inquiry (AI) as a form of organizational change. He defines AI as the: “search for the best in people, their organizations, and the relevant world around them. In its broadest focus, it involves systematic discovery of what gives “life” to a living system when it is most alive, most effective, and most constructively capable in economic, ecological, and human terms. AI involves, in a central way, the art and practice of asking questions that strengthen a system’s capacity to apprehend, anticipate, and heighten positive potential. It involves the mobilization of inquiry through the crafting of the “unconditional positive question” often involving hundreds or sometimes thousands of people.”59 His approach is based on the assumption that the process of inquiry can create what it is questioning. A manager asking “Have we stopped thinking about pink elephants?” causes the organization to think and talk about pink elephants. Similarly, attempts to “stop sexual harassment in the workplace” through classes and education can have the effect of increasing the incidence of sexual harassment complaints. If we look at organizations as problems to be solved, we find an ever-increasing number of additional problems. This is the realm of deficit discourse. Flipping the questions to positive discourse, our questions seek strength and positive interaction. Instead of “how do we ignore pink elephants?” the question becomes, “How can we focus our attention on accomplishing our goals?” Instead of fighting sexual harassment, the question becomes, “When have we had positive crossgender quality work relationships?” Cooperrider lists five principles of appreciative inquiry: Constructionist principle: the way we know is fateful. If we choose to understand a system according to its deficits, we are not only limiting our ability to understand its positive attributes, but we are creating additional deficits. Principle of Simultaneity: Changes begin the moment we ask the question. Poetic Principle: Organizations are an open book, creating themselves according to the metaphors they choose in internal discourse. 59 Cooperrider, David, et al, Appreciative Inquiry, Rethinking Human Organization Toward a Positive Theory of Change, Stipes Publishing, 2000, p. 6 46 Anticipatory Principle: Deep change is stimulated in an organization’s active images of the future. Positive Principle: The more positive the question, the greater and longer-lasting the change. He lists several ways in which positive images can create positive action: Placebo effect. A person or organization’s expectation has a powerful influence on the outcome of an interaction. Pygmalion effect. Research has repeatedly shown that the way that teachers were introduced to their students has dramatically affected a student’s progress. Those who were randomly introduced as high performers outperformed those who were of the same skill level, but introduced as low performers. Imbalanced “inner dialog.” People and organizations who focus exclusively on negative discourse will have lower performance than those who maintain a more positive balance. Deficit Discourse in Health Care There are many examples of deficit discourse in the health care industry. For example, a recent issue of Health Affairs Journal spoke of deficits by people’s race, immigrant status, mental health, and substance abuse. Efficiency was defined as “low cost.” The ability of health care consumers to understand more complete information was questioned. One physician spoke of his patients: “little did they know that they “belonged” to their IPA (which they had never heard of) – not their physician and certainly not themselves.”60 The predominant metaphor was that health was a scarce resource to be allocated according to supply and demand as well as regulation and enforcement, rights and entitlements. Psychologist Kenneth Gergen sees deficit discourse as a contributor to the growth of a profession: “Interestingly, this dramatic expansion of the identified disorders roughly parallels the growing numbers of mental health professionals…we find ourselves facing what appears to be a cycle of progressive infirmity: consider the phases (1) as mental health professionals declare the truth of a discourse of dysfunction, and (2) as this truth is disseminated through education, so do we come (3) to understand ourselves in these terms. (“I’m just a little depressed.”) With such an understanding in place, we will (4) seek out mental health professionals for a cure. As cure is sought, (5) so is the need for mental health professionals expanded. And (6) as the 60 Project Hope, Health Affairs Journal, July/August 2000 47 professional ranks expand, so does the vocabulary of mental disorder prosper. Is there a limit to the dysfunctional disciplining of the population? I recently received an announcement for a conference on the latest research and cure for addiction, called, “the number one health and social problem facing our country today.” Among the addictions to be discussed were exercise, religion, eating, work, and sex. If all these activities, when pursued with intensity or gusto, can be defined as illness that require cure, there seems little in cultural life that can withstand subjugation to the professions.”61 Clearly, there are problems that must be dealt with directly in the health care process. At the same time, however, we need to strike a balance between positive and negative discourse. Technology to Support Positive Discourse Positive discourse can have dramatic effects on our health. For example, Spiegel62 reported that metastatic breast cancer patients who were randomly assigned to a professionally led support group not only enjoyed a higher quality of life than similar patients not in a support group but also lived twice as long, an average of 18 months longer. The Internet provides several key capabilities that can be used to support positive discourse for health. Flexible communications Scalability Generative spaces Flexible communications. Participants in cyberspace communications do not have to be close in space or time. Messages can be entered and retrieved as needed by the sender and receiver. Participants in a community are not necessarily there all the time; they can come and go according to their own needs. Information and knowledge that can be expensive to generate can be communicated at very low cost. Scalability. Cyberspace is not physical; it is nowhere and everywhere at the same time. Furthermore it is scalable. It can be very small and cozy, or large and open to many participants. There is no inherent limitation on the size of the space, nor its characteristic size. For example, Amazon.com may be the “world’s largest bookstore,” but repeat customers are provided with a personalized list of suggested books, based on their personal purchasing history as well as customers similar to them. The bookstore is large and comprehensive as well as cozy and personal. In the same way, Internet technology 61 Gergen, Kenneth, Invitation to Social Constructionism, Sage Publications, 1999, p. 40 D. Spiegel, J.R. Bloom, et al. "Effect of Psychosocial Treatment of Survival of Patients With Metastatic Breast Cancer." The Lancet (October 14, 1989): 888-891 62 48 can create a large and comprehensive space for health and information, as well as a cozy and personal space for individual needs. Technology can be used to blend these together in an innovative manner, free from the constraints of physical space and physical meetings. The benefits of positive discourse are scalable – that is, the greater they are used, the greater the motivation to do more. Generative Space. Cyberspace differs from physical space in critical way. Cyberspace does not “fill up” as does physical space. When a store moves into a shopping mall, it shrinks the space available for other stores. When a web site goes online, rather than taking up space, it increases cyberspace. In this sense, it is generative. The more people who join the space, the larger it becomes. It is possible to think of health as a generative space. The healthier people become, the healthier everyone else becomes. The more people enter the space, the larger it becomes. Health becomes an open, inclusive concept, generating ever more interest in an ever-broadening spiral. People becoming healthier do not fill up the health space any more than new web sites fill up cyberspace. Positive Metaphors for Health The World Health Organization proposed that health transcends the mere absence of disease and should be viewed more broadly as a state of complete physical, mental, and social well-being.63 An Institute of Medicine committee expanded the WHO definition of health as follows: “Health is a state of well-being and the capability to function in the face of changing circumstances. Health is, therefore, a positive concept, emphasizing social and personal resources as well as physical capabilities. Improving health is a shared responsibility of health care providers, public health officials, and a variety of other actors in the community who can contribute to the well-being of individuals and populations”64 Peter Drucker’s summation of management is to “create ways to aligning strengths while making weaknesses irrelevant.” How can we do this for managing our health? In order to make this shift, we need new metaphors. One approach is to think of the VA as an entity that supports health transformations, building on the positive concept of health. 100 Million Health Transformations What if the VA imagined itself as an organization to support 100 million simultaneous health transformations? These transformations would be personalized to the 26 million individuals or groups that make up the VA population. Each transformation would occur within its own ensemble, a community of people, resources, and agents focusing on a common purpose. Ensembles could be as small as a 63 World Health Organization, Constitution of the World Health Organization, Geneva, Basic Documents, 1994 64 Institute of Medicine, Improving the Health in the Community: A Role for Performance Monitoring, Washington, DC, National Academy Press, 1997 49 consultation about a single person’s problem. Or, they could be as large as a nation-wide concern, for example, all those interested in the Persian Gulf Illness. Thinking of health as transformations occurring within ensembles allows us to rethink health and how it is supported65. The concept is a fertile foundation for innovative thinking about health: It introduces new notions of scale to health. Web technology provides an infrastructure for connectivity and mass personalization unthinkable just a decade ago. Systems can be designed to support massive numbers of participants at a relatively low cost. It makes self-organization feasible. People can discover their own resources for managing their own health transformation. Providers can direct patients to ensembles and resources as appropriate. Things that can be reduced to bits of information can be replicated and communicated at very low cost. One expert’s advice can be captured once, and communicated many times. It puts a new emphasis on patient self-efficacy. Patients will find themselves more responsible for their own health. It introduces new notions of management and control. VA cannot be expected to manage 100 million things simultaneously. Rather, the transformations must become self-organizing. This concept raises other issues: 65 It creates new problems of information overload, access, and ability of Veteran’s to understand and communicate in the information era. This requires innovation to allow access, train assistants and family members, and publicize the process. How are these transformations infused with appropriate clinical expertise and medical knowledge? What are the constraints limiting these transformations? How do we protect against fraud and quackery? How do we insure that transformations occur are as safe as possible? How do we configure medical knowledge and research to maximize its benefit to this massive number of transformations? http://www.munnecke.com/papers/D16.doc 50 Example of Appreciative Health Inquiry The appreciative inquiry model could be introduced directly into the clinical process: Dialog Dr (at beginning of visit): “Tell about the time you felt most healthy and alive?” Dr. listens to Patient response “How can we use that vitality to help us today?” Dr. refers to these strengths in the course of the exam, either as reinforcing chit-chat or a foundation for additional health care instructions At conclusion of visit: “What are you going to do to improve and maintain your health until we next meet?” Strengths and expectations noted on the medical record for future communication. Effect Puts the patient in an upbeat mood, opens up positive dialog, establishes positive rapport, begins placebo process, lets patient know that they are expected to participate in this process. Opens door to additional conversation, but not simply in the “complaint” mode of discourse. Asks patient to think of ways of helping themselves; draws on personal strengths, transfers physicians authority and trust to the individual. Establishes shared meaning during the visit, grounds instructions in a positive, optimistic context which the patient can understand and relate to. This places the burden on patients to think about their own health process, and the instructions given during the visit. It introduces a positive expectation in patients – they can do something on their own to improve their health. It confirms the instructions given during the visit, and opens up a dialog for further discussion This will establish positive rapport in future visits. Knowledge that physician will be asking about their health process will encourage patients to adhere to them more aggressively. Patient Safety Success Dialog An Appreciative Inquiry approach to the patient safety issue would be to create a dialog around successful instances of activities that improved patient safety. Sample questions to medical professionals might be: In your career as a health care professional, when have you felt most productive and successful in creating an environment of patient safety? 51 Imagine you were to fall asleep and awaken 10 years from now. The health care system had changed to become much safer. What would that system look like? What are the ways in which we can improve the safety of delivery of health care? On Line Support Groups There are a profusion of on-line support groups dedicated to specific communities. One group is called The Healing Exchange Brain Trust, whose mission statement is: Our nonprofit mission is to provide, promote, and improve communication opportunities and tools for people who are personally affected by or who professionally treat or study localized neurological disorders and subsequent or related health care concerns. T.H.E. BRAIN TRUST Vision is threefold 1. The communication vehicles created, supported, offered or endorsed by T.H.E. BRAIN TRUST are intended to enable, encourage and empower local and international exchange among Survivors, their families and supporters, health professionals and researchers. 2. The group experience will become a new type of health resource -- a collected wisdom -- which should be conveyed to the broader health care community and the public in order to foster acceptance, understanding and aid for persons coping with neurological abnormalities and to increase public awareness of and to further develop innovative resources for anyone needing them. 3. T.H.E. BRAIN TRUST seeks to emphasize how health care and the human spirit unite towards achieving healing and well being. We seek to recognize participants in the health care process as patients/survivors/families/consumers and providers/professionals/caregivers but most importantly seek to unite these groups by embracing the humanity of all. One of their primary activities is a mailing list of about 1,000 people called BRAINTMR. Some examples of how BRAINTMR is used are: 66 66 For patients and families dealing with the same tumor type to "meet" To find out WHO is doing WHAT brain tumor research To address emotional aspects of patients' brain tumor treatment http://www.braintrust.org/services/support/braintmr/ 52 To discuss the impact of brain tumors on individuals, society and the practice of medicine To discuss other intracranial malformations (such as the AVM) Over time, other groups have formed for more specialized communities. For example, The Brain Trust web site introduces group dedicated to Adult Ependymoma: “The Adult Ependymoma Group is currently a group of approximately fifteen adults, including patients, caregivers and relatives. The size of this group is consistent with the rarity of ependymomas in adults. The "advantage" to the size of this group is the incredibly close and powerful bond the members have formed. Currently the group serves as an emotional and medical support system for one another. The members have expressed numerous times how invaluable this connection is to their survival in the world of brain tumors.”67 The advantages to online support groups are many: 67 They are relatively inexpensive to set up and operate. They can be self organizing They are scalable. They can serve small or large groups, depending on the needs of the community. A little knowledge goes a long ways. A single subject matter expert can participate in the group to provide professional input and interpretation to the group. They can be accessed 7 days a week, 24 hours per day. They can deal with very broad or very narrow topics, as appropriate to the group. They can be as open or closed as necessary. They can be used to support VHA’s goal to build healthy communities. At very low cost, online support groups sponsored by VHA and staffed by VHA subject matter experts could be opened to the community in general. They could be a conduit to medical research. VA researchers in specialized diseases or conditions could be linked directly with support groups consisting of those with a special interest in that topic. They could provide a creative outlet for VHA employees wishing to leverage their knowledge and education to a broader audience than that constrained by physical office meetings. http://www.braintrust.org/services/support/othergroups/index.html#adultependy 53 Health and the Devil’s Staircase68 René Dubois likens modern medicine to a wild west thriller: “In the crime-ridden frontier town the hero single-handedly blasts out the desperadoes who were running rampant through the settlement. The story ends on a happy note because it appears that peace has been restored. But in reality the death of the villains does not solve the fundamental problem, for the rotten social conditions which had opened the town to the desperadoes will soon allow others to come in, unless something is done to correct the primary source of trouble. The hero moves out of town without doing anything to solve this far more complex problem; in fact, he has no weapon to deal with it and is not even aware of its existence.69” (Italics added) There are many heroes in today’s healthcare environment, and there are also severe underlying problems that are being ignored. One manifestation of this is the exploding complexity of our systems. We are gaining ever more precise understanding of an exploding amount of knowledge. The yardstick by which we measure the medical universe is shrinking to ever more precise dimension. As levels of precision and specificity rise, so does complexity. Modern society is driven by a lust for precision that in many cases outstrips its needs. The Dow Jones Industrial Average is broadcast with a precision of seven significant digits. Colleges calculate grade point averages to four, in spite of what students are taught about precision in their science classes. President Clinton, in his January, 2000 State of the Union speech, said that Americans, based on their genetic sequences, were 99.9% the same. Had he chosen to use amino acids as the yardstick of similarity, he could have claimed 100%. Had he chosen hair color, the number may have dropped to the low teens. Had he chosen fingerprint patterns, he could have made the case for 100% uniqueness. The same species viewed with different yardsticks reflect wildly different comparisons. Health and our healthcare system are subject to the same problems of scale and perspective. The same thing, viewed with different yardsticks, can have wildly different results. One way to address this problem is to address the notion of complexity as topic in itself. Like the gunfighter in Dubois’ allegory, those involved with the heroic solutions to healthcare problems may not have all the weapons or tools they need, nor even be aware of its existence. Actions taken to cure an individual or an entire healthcare system may fix one problem but exacerbate others. Complexity feeds on itself, each iteration contributing complications for the next. Murray Gell-Mann, Nobel laureate in physics for his work in discovering the Quark, speaks of this problem: “We need to overcome the idea, so prevalent in both academic and bureaucratic circles, that the only work worth taking seriously is highly 68 Munnecke, Tom, Business Enterprise Solutions and Technologies, Veterans Health Administration, Department of Veterans Affairs, Jan 2000 69 Dubos, Rene, Mirage of Health: Utopias, Progress, and Biological Change, Harper, 1959, p. 162 54 detailed research in a specialty. We need to celebrate the equally vital contribution of those who dare to take what I call “a crude look at the whole.”70 The Devil’s Staircase Mathematicians speak of a construct called the Devil’s Staircase.71 Viewed from a distance, the staircase looks like a rough set of steps. However, it has an insidious property in that the closer we look at the curve, the more steps it has. In fact, as we look at infinitely small sections of the staircase, we find infinitely many steps. This provides a rich metaphor for looking at systems. The quest for ultra fine precision can cause us to sink into the devil’s staircase, defeating our ability to have a “crude look at the whole”. The notion of scale took a revolutionary turn with Benoit Mandelbrot’s discovery of fractals in the 1970’s. As a fractal object is magnified, ever finer features are revealed. The shapes of the smaller features are similar to the shapes of the larger features. Notions of dimension that have been taught since the time of Euclid no longer apply. Imagine that we are trying to measure the length of the coastline of Great Britain. If we follow the edge of the island on a map with a dividers set to 1000 km, we will find one length. If we set the dividers to 100 km, we will measure a longer length, because the segments spanned by the dividers measure greater detail. If we move to progressively smaller scales to 10, 1, .1, .01, .001, .0001 km, etc. we will find a progressively longer coastline. The length of the coastline varies with the length of the yardstick we use to measure it: “Typical coastlines do not have a meaningful length! This statement seems to be ridiculous or at least counter-intuitive. An object like an island with some definitive area should also have some definitive length to its boundary.”72 The length of the coast is dependent on the scale with which we measure it. This is different than understanding objects according to the geometry of Euclid. If we were measuring a coffee cup, the smaller the scale with which we measure, the more accurately we would know its circumference. We could take a number of measurements, then take the mean in order to get even more accuracy. Measuring a coffee cup and measuring a coastline, it turns out, are extremely different problems. The differences between the coffee cup and a coastline are not just a mathematical curiosity – they illustrate a fundamentally different way of understanding the world. There are far more fractal problems out there than first meets the eye. However, the intellectual paraphernalia we have developed over the past centuries is based on the assumption that we are able to use the coffee-cup style of metrics. The yardstick (and therefore, scale) with which we view a problem has profound effects on what we see. In many cases, the smaller the yardstick, the greater the problem. Yet we have an intellectual ethic that respects only ever-finer investigations at only a 70 Gell-Mann, Murray, The Quark and the Jaguar, Adventures in the Simple and the Complex, W.H. Freeman and Co, 1994, p. xiv. 71 Peitgen, Heinz-Otto, et al, Chaos and Fractals, New Frontiers of Science, Springer-Verlag, 1992, p. 220 72 Peitgen, et al, p. 184 55 specific scale. Like Dubois’ wild west gunmen, we are unaware of entire cascades of problems which occur outside of scope of a specific scale of thinking. We have precious few intellectual weapons to address these multi-scale problems after the single scale gunfighters have left town. The Notion of Intrinsics One way to attack the concept is to imagine a system as being composed of many layers. The bottom scale addresses the problem at the smallest scale, and each succeeding layer deals with the problem at a larger scale. One sequence of layers for health may be: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. Gene Cell Immune System Organ Individual Family Community Nation Race Species Rather than look at a problem at only a single layer, we drill down through all the layers simultaneously. Things that connect through the different layers can be called intrinsics. Intrinsics are scale-independent properties which are found at many or all of the scales at which a system operates. For example, vitality can be viewed as an intrinsic of health. We can speak of vitality at many different scales: of a cell, organ, person, family, community, nation, race, or species. This perspective does not refute the biologist that studies the cell or the sociologist that studies community. Nor does it seek to “integrate” the fields of biology and sociology. Understanding systems through scale-independent intrinsics is fundamentally different than traditional “interdisciplinary” approaches. Intrinsics are based on the concept of self-similarity across scale, whereas intellectual disciplines arise from examining a system at a specific scale. The integration of mutliple, scale specific disciplines triggers a “scale crunch” where the two specialists struggle to retain their scale-specific understanding while simultaneously interacting with others. These specialists have already sunk into the devil’s staircase. Attempts to make their positions more explicit only drive them deeper into the very problem they are trying to solve. Scale-specific disciplines are often linked to notions of predictability, repeatability, objectivity, and assumptions of linearity. They narrow their scale of examination, excluding “externalities,” “outliers,” and “non-normalized” information. They assume Gaussian distribution for their fields of study, and seek to define causal relationships within these confines. Intrinsics, operating simultaneously at all scales, are not easily boxed into singlescale thinking. They create a cascade of interaction, acting at many scales 56 simultaneously. Like the coastline of Great Britain, any single yardstick we use to evaluate and understand a specific cascade will only deal with a partial slice of reality. The cascade of vitality that engulfs our daily world is easily seen on a visit to a park on a spring day. The infectious enthusiasm of children playing, the appearance of new flowers and buds, the young couples entertaining thoughts of the next generation, and the older generation watching it all are all manifestations of William Blake’s “To see the world in a grain of sand.” While poets and mystics revel in such observations, we have a scientific tradition that has difficulty dealing with cascades of activities at multiple scales, happening simultaneously. Consider, for example, the cascade of interactions between a nursing mother and her infant. By analyzing mother’s milk at the chemical level, we can recreate it in a stable, easy-to-mix formula that can provide a large percentage of the nutrients found in mother’s milk. We could even quantify the similarity between the two, for example, that formula contains 98% of the nutrients found in mother’s milk. This approach makes several assumptions: 1. That the scale at which we are analyzing mother’s milk is appropriate. For example, we could say that the formula had exactly the same ratio of amino acids as mother’s milk. Although this ratio could be proven exactly true, the net effect of the concoction would likely have little nutritional effect. 2. That there is some yardstick by which we can claim 98% complete. Is this 98% by weight, volume, active ingredients, or other measure? 3. That this yardstick is linear – we can add together components together to get 100%. 4. That we understand the missing 2% of the formulation. Are these missing ingredients something vital to the infant, even if in trace quantities? 5. That there is an “average” mother’s milk that serves as the basis from which the 98% analysis is completed. Let us examine the system from another scale – the dynamic interaction between mother and infant. Nursing is a bidirectional process, by which the baby receives nutrition, emotional support, comfort, warmth, touch, massage, cooing sounds, heartbeat sounds, love, and bonding with the mother. Other than the specific transfer of chemical nutrients, the mother receives much of the same from the baby. The mother may have feelings such as reassurance that she is a worthy mother, a sense of being needed, a sense of wonder at the mysteries of childbirth, hope for the future, happiness that her labor and hard work to bring a child into being was worth it, resolution of fears and anxieties, and an array of other emotional feelings. This cascade of interaction is far removed from the chemical process of providing nutrients to her baby. This multi-scale perspective negates many of the assumptions of the single-scale chemical/nutritional analysis: 1. The mother and the baby are interacting with each other simultaneously at many different levels. Communication is no longer a one-way process based on average nutritional content, as viewed by chemical/nutritional yardsticks. 57 2. There is no yardstick by which to measure the mother/infant nursing dialog. We can not claim that a mother is receiving 74% of her sense of wonder or the baby 98% of its emotional support from a particular nursing session. Even more remote is the possibility of aggregating these factors into an overall quantity, to claim that a nursing session was 74% successful. 3. There is no way to characterize an “average” nursing process. Each mother and each infant are different, and each nursing session has its own context. This scale of thinking is difficult to handle from a scientific, rational point of view. Management textbooks teach, “If you can’t measure something, you can’t achieve it.” Science demands objectivity, an observer outside the system being measured who is free of investigator bias. It expects falsifiable hypotheses, which the objective observer could disprove according to scientific methods. Nature, however, is hampered neither by the limitations of analysis nor the scientific method. Nursing has been experienced successfully by billions of mothers without any rational explanation or analysis. The Yardsticks of Health In the field of health, there is an intimate relationship between yardsticks and their effect on the systems we examine. What are these yardsticks, and are they fractal in nature? Some of the areas in which fractal dimension has been measured are: - Pulmonary hypertension Surfaces of proteins Surface of cell membranes Shape of herpes simplex ulcers in the cornea Growth of bacteria colonies Islands of types of lipids in cell membranes Dendrites of neurons Blood vessels in the eye, heart, and lung Blood flow in the heart Textures of radioisotope tracer in the liver Action potentials from nerve fibers Opening and closing of ion channels Vibrations in proteins Concentration dependence of reaction rates of enzymes.73 Fractals are not isolated to the dimension of space, but that of time as well: “The fractal concept can be applied not only to irregular geometric or anatomical forms that lack a characteristic (single) scale of length, but also to complex processes that lack a single time scale. Fractal (scale-invariant) processes generate irregular fluctuations on multiple time scales, analogous to fractal objects that have wrinkly structure on different length scale. 73 Liebovitch, Larry S., Fractals and Chaos Simplified for the Life Sciences, Oxford University Press, 1998, p. 69. 58 …complex fluctuations with the statistical properties of fractals have not only been described for heart-rate variability but also for fluctuations in respiration, systemic blood pressure, human gait, and white blood cell counts.74” Goldberger goes on to link the absence of the fractal cascade to the disease process: “The antithesis of a scale-free (fractal) system – i.e., one with multiple scales – is one that is dominated by one frequency or scale. A system that has only one dominant scale becomes especially easy to recognize and characterize because such a system is by definition periodic – i.e. repeats its behaviour in a highly predictable (regular) pattern.. The paradoxical appearance of highly periodic dynamics in many disease states (disorders) is one of the most compelling examples of the notion of complexity loss in disease. Complexity here refers specifically to a multiscale, fractal-type of variability in structure or in function. Many disease states are marked by less complex dynamics than those seen under healthy conditions. This decomplexification of systems with disease seems a common feature of many diseases, as well as aging. When physiological systems become less complex, their information content is degraded. As a result, they are less adaptable and less able to cope with the exigencies of a constantly changing environment. Remarkably, the output of many severely pathological systems has a nearly sinusoidal appearance. An example is the sinus-rhythm heart-rate variability sometimes seen in patients with severe congestive heart failure, or with the fetal distress syndrome.75” If health is a fractal concept, then our attempts to understand it using single-scale metrics rob us of our understanding of the full cascade of interactions. In the same way that congestive heart failure can create a perfectly orderly sinus-rhythm heart waves, our attempts to control our health care system with perfectly orderly regulations and standards may indicate pathology. The richness and the generative cascade of multi-scale understanding is a measure of robustness and vitality. This is the weapon that our gunslingers are missing. Goldberger, Ary, “Non-linear dynamics for clinicians: chaos theory, fractals, and complexity at the bedside,” The Lancet, May 11, 1996, Vol 347, No. 9011, p 1313 75 ibid, p. 1313 74 59 Personalizing Health76 One of the many complaints directed at large health care organizations and government agencies is that they are impersonal bureaucracies. Patients complain that “the system” does not meet their needs. It goes too far in some ways, yet not enough in others. Employees of these organizations have similar complaints. They feel frustrated with the rules, and feel limited in their ability to take initiative to serve their patient population. They, too, blame “the system.” This paper proposes an alternative – personalization. It reframes the notion of the system to be “pro health” rather than “anti disease.” The notion of health is a highly personalized matter, not simply an average of aggregates. Depersonalization “Bureaucracy develops the more perfectly, the more it is dehumanized…the professional bureaucrat…is only a small cog in a ceaselessly moving mechanism which prescribes to him an essentially fixed route of march.”77 The common thread connecting all of these problems is depersonalization – the notion that the individual is a passive object to be acted upon by the system. The doctor knows health, it is the responsibility of the patient to be compliant and receive the benefits. As Philip Howard says of the spiral of our culture into ever more legalistic and bureaucratic control: “One of the dreadful curses is that we are making diversity illegal.” The common solution to these problems is personalization – the notion that the individual is responsible for their own success. The purpose of the system is to enhance that success, not control it or limit with expectations that others are responsible. It recognizes and supports diversity – the personal health context of the individual The World Wide Web is a fascinating case study in this process. We need to look beyond the technology and gadgets of the web – one pundit described our current fascination with web technology as like going to a movie and staring at the projector. We are experiencing a profound shift in how we deal with large scale, complex systems. There is no CEO to the web, no central authority, no single starting point. Users must create their own center – they are personalizing the web from their particular point of view. They control the success or failure of web sites by simply clicking on what interests them. Sites that get many clicks thrive; those that do not, fade away. Such is the law of the web jungle – consumer attention drives the evolution of the web. It is possible to imagine a similar dynamic in health, driven by the notion of personalization. Those who are able to deliver their information, goods and services in a manner that meets the personal needs of the individual will thrive. Those who do not will fade away, replaced by those who have met the personalization needs of the population. 76 Munnecke, Tom, Veterans Health Administration, May, 2000, Department of Veterans Affairs 77 Howard, Philip K, The Death of Common Sense, How Law is Suffocating America, quoting German Sociologist Max Weber at the turn of the century 60 Depersonalization is not just a consumer/patient problem. Those employed by the health care industry feel the same way – that the system is controlling their decisions and freedom. It is not allowing them to be the scientist, healer, or care giver that they sought when they started their career. They have the same needs for personalization as the patients they serve. They suffer from the same depersonalization as the patient. Viewing health from a personal point of view is radically different than from the point of view of the “system.” This inversion of perspective, however, is key to understanding and transforming the health care system. The dynamics of the current anti disease system is much like trying to get out of a hole by digging it deeper, and measuring progress by how much dirt is being thrown about. There will be those who believe that the average person is not capable of making their own health decisions. Imagine this attitude at the time of Gutenberg, “Why do we need so many books? No one can read them.” They would have failed to see the literature/literacy spiral that the printing press created. They would have been fearful that lay people would be interpreting the Bible directly, without interpretations by priests. So it is with health information. The web is feeding the health literacy/literature spiral, with or without intervention or the control of the medical profession. Authority which used to be assigned to the system is being replaced by communication, as health is personalized to the individual. This transition is appearing in the market today, under the rubric of “e-health” and “e-medicine.” A RedHerring.com message describes this, in the context of the successful IPO of the DrKopp.com web site: "Drkoop.com is the opening salvo for a new industry -- e-medical," says Irv DeGraw, research director of financial information site Stockstowatch.com. He expects this to be a top sector next year. I once helped an elderly aunt by replacing an old dial-style telephone with a lighted, large button model. She grew up in the era when telephones were the property of the telephone system, not to be touched by homeowners. She giggled when I showed her the new telephone, as if we were doing something illegal. I could never fully convince her that times had changed, and customers were free to buy and install their own telephones. A similar attitude has been instilled by the health care industry. It is almost as if your health is the property of your provider, a benefit provided to you according to the rules and regulations of the system. Like my aunt who was never quite comfortable with the notion that she owned her own phone, we have created a system in which people do not believe that they are responsible for their own health. The convergence of e-health and the Internet may trigger a major shift in the public’s thinking. A Foundation for an Epidemic of Health Jonas Salk concluded that the solution for our health care crisis was to create and epidemic of health.78 This is a rich metaphor for thinking about health, rather than just Appendix A is a report of a meeting held in Washington on May 3, entitled, “Creating an Epidemic of Health.” 78 61 “anti-disease.” It also forces us to consider just what is meant by the concept of health, and how the system supports it. The explosive growth of the web provides a role model for this kind of process. The web began very simply, and evolved according to a fitness function within a set of constraints. The fitness function for success was very simple, that which people paid attention to, thrived. The dynamics of the epidemic of health can recapitulate the web experience in many ways, personalization being a key factor: Attribute Initial Conditions Web URL, HTTP, HTML Constraints Internet Protocol Fitness Function Emergent Properties Attention Yahoo!, Amazon.com, eBay Epidemic of Health Connectivity, Interest in Health, Mutuality Privacy, Safety, Public Health Personalization ??? Personalization is to the epidemic as attention is to the web. Just as successful web sites drew attention, successful health entities will offer personalization – information and knowledge in the context of the individual. Personalization has a rich variety of meanings. We see it emerging on the web as “My Yahoo!” type of sites, where individuals are able to customize their web site. It is also a reaction and a repair of what was caused by depersonalization – that people are all just cogs in the machine. Trust the system to take of you.. Rules and regulations are responsible for proper functioning, your role is to be a passive participant. Your box on the organization chart defines your freedoms and responsibilities. If things go wrong, the system needs to have additional rules and regulations to fix it. If there is a failure to communicate, more authority and policing will compensate for it. We have turned health into a “market,” where “consumers” have “benefits” given to them by health care “providers,” allocated according to the laws of supply and demand. Taxes, employer contributions, and individual’s money are all pooled in a reservoir, from which they withdraw their health care. Consumers expect their providers to take care of their health, not unlike the way that they expect a mechanic to take care of their car. If something goes wrong, malpractice lawyers will step in, and on a contingency basis, will retrace all of the steps leading to the wronged action. But is this what health is about? Is health something that can be bought and sold according to supply and demand? Is health really a zero sum process, where one person’s increase in health demands someone else’s corresponding decrease? What exactly is the market allocating? Do the uninsured not have health? When they read, “see you doctor before beginning an exercise regimen,” should the fact that they cannot afford a doctor keep them from exercising? 62 “Despite the superb achievements of medicine, our best hope for a healthy life is not medical care, but self-care. Current medical evidence, which implicates violations of lifestyle, environment, and diet as the driving forces in chronic disease, shows that many of us are not conducting our lives in a healthy way. Health as subjective behavior is ignored in favor of health as an objective entity that the designated expert (the doctor) ensures and maintains…This abdication of responsibility undermines the development of healthy attitudes and healthy behavior.”79 Paradoxical Control It is possible that the attempt to control something will create more of the very thing it is attempting to stop. For example, imagine that we want to make sure that people do not think of pink elephants. We pass anti-pink elephant promotion laws, and have regular surveys to see what proportion of the people are not thinking about pink elephants. When these surveys show an alarming increase in pink elephant thinking, we decide to “declare war on pink elephant thinking” with billboards, etc. Everything we do to prevent pink elephant thinking seems to make it worse. There are parallels between this analogy and the health care industry. We think of health as fighting disease, rather than accentuating health. Responsibility is shifted to the system, not the individual, and it is defined from the system’s perspective, not the individual’s context. If we take one extreme of the disease-prevention model – defeating death - we would create a system in which the entire US population would end up on life support systems. If we take the other end – minimize costs – we would spend nothing because every one is going to die anyway. If we dichotomize the industry in this manner, we are faced with a choice…we spend X percent of our resources on defeating death, and 100X% minimizing costs. The decision descends to “what is the appropriate value of X” rather than challenging the fundamentals of the situation. I think that we need to ask, “how do we maximize the vitality and health of the American public?” We need to think about “pro-health” metrics rather than “anti-disease.” Unfortunately, nearly every measure of quality and control in use today is based on disease, diagnosis, and aggregation, rather than health, self efficacy, and personalization. The challenge is how to bring long term, goal oriented, transformational values into the short term, immediate transactional metrics of our current organization. We need a number that “bottom line” thinkers can use to manage and control their organizations. This kind of transformational information system is not generally available. Ecologists speak of full cost pricing, in which the full environmental costs of goods and services are priced into the sales transaction. The RealAge approach (http://www.realage.com) is a transformational metric. Individuals who take the questionnaire are able to calculate the difference between their chronological age and their health risk adjusted “real age.” Thus, the transformational value of lifestyle modifications and behavioral modifications are reflected in the 79 Beasley, Joseph D, MD, The Betrayal of Health, The Impact of Nutrition, Environment, and Lifestyle on illness in America, p 238 63 individual’s age. These age differentials can used as organizational metrics, allowing traditional aggregation and analysis. Health Management = Wealth Management? Consider developing the US Department of Wealth, universities devoted to Wealth Care Sciences, professional wealth care providers giving wealth back to their customers, and the wealth care insurance industry. People would be advised not to spend their money until they got approval from their wealth care provider. The exploding complexity of the US wealth care industry would trigger a call for standardization, so that the wealth care providers could insure that they gave the unambiguous and proper advice to their clients. Lacking an accepted definition of wealth, the industry would break it down into components; others would create the holistic wealth movement, alternative wealth care providers would provide a “counter culture” to the oppressive, hierarchical wealth care establishment. A revolutionary movement arises, in which wealth is personalized. Each person would be responsible for their own wealth, and it would be a private matter. If they chose to have professional help managing their wealth, that is their decision. The wealth care industry vehemently opposes this movement, saying that people would spend their money in foolish ways, would not understand all of the nuances of wealth developed by the specialists over the years. People may violate standards of wealth management, and many would squander it away. People would go broke and end up on the street. “Our country has the best wealth care management system in the world” they would say. The revolutionaries would say that wealth has to be managed by the individual, according to their particular context. The notion of wealth changes according to how much they have, their family and social context, their personal support network, age and a host of other issues. There is no one correct way to wealth, everyone has to learn this for themselves. We have a vibrant and successful wealth management system today – our economy. We do not need to have government agencies deciding how much milk should be delivered to San Diego each day. We do not have a universal credit card identifier associated with each consumer, but rather allow the individual to manage their funds as they see fit. We manage the system by managing the environment, rather than each specific economic interaction. Most Americans have grown up thinking that they would be responsible for their own money management. The same attitude can be applied to their health. Millions of little things A Korean War Veterans web page has testimony by one of the users describing getting a “little bit healthier” for having accessed the page. Given that the page could be accessed by millions of people, how do we measure the effect of millions of people getting a “little bit healthier?” What would be the benefits of investing $5 million in a new MRI unit, compared to supporting 100 web sites, each accessed by 1 million people, getting a little bit healthier? How do we decide such things? “A little bit of health” is a highly subjective thing. One person may find the Korea page to be highly cathartic, while others may be disinterested. 64 An example of a small action being replicated for major effect can be seen in the Grameen bank of Bangladesh. This is a bank, owned 92% by its borrowers, which serves some of the poorest people in the world, by offering them loans with which they can buy basket materials, a sewing machine, or other acquisitions to improve their lives and jobs. It is not a charity – the bank expects full interest – yet it is able to transform the lives of millions. It now serves 2.34 million members in 38,957 villages, with total savings of about $162 million. The average household income of Grameen Bank members is about 50% higher than non-members . What started as an innovative local initiative, "a small bubble of hope", has thus grown to the point where it has made an impact on poverty alleviation at the national level." The Grameen bank has personalized capital. Poor, uneducated women mired in great poverty have been able to band together and raise their living standards en masse. The “small bubble of hope” has been magnified millions of times over. The Grameen Bank is an example of a totally self-reliant poverty-eradication initiative that does not need a handout to sustain itself or its growth. The poor own and run the bank and pay for their "development." This success story contrasts with the many failures of impersonal, large scale development projects such as dams and irrigation systems. Presuming the money allocated actually makes it to the megaproject, it frequently is a mismatch for the local culture. Rather than improving the lives of the local people, it can cause huge dislocations in the local culture – achieving the opposite of its goals. There are parallels between the way the Grameen bank has personalized wealth and how we can personalize health. Grameen amplified a “small bubble of hope,” while the Korean Veteran’s page, amplified “a little bit healthier” across a broad population. Are there other ways in which a small amount of health capital can be leveraged across a large population? The scalable communications technology of the Internet can be used to make this happen. Techniques for Personalizing the VA Some ways in which the VA could personalize its services to the Veterans are: Personalization Technique Create metrics which allow the organization to deal with its long term, goal oriented values to the individual. Apply these metrics as organizational intrinsics, regardless of hierarchical scale or scope. Everyone in the organization should understand their role in achieving these metrics. Create an information system which would allow the management of information 80 Example Use RealAge80 age reduction metric for veterans to manage their health affairs. Develop additional metrics specific to veterans. Measure management on the aggregate age reduction as indicated by the RealAge metric above. Work into “Vision for Change” type of document. Implement Health e-Vet program to create a veteran-specific information space, Roizen, Michael, MD. RealAge, Are you as young as you can be?, HarperCollins, 1999 and http://www.realage.com 65 according to the needs of the individual. Create an environment in which trust, community, and mutuality can thrive. understandable and controllable by them. Implement a “buddy system” whereby veterans who have been through a treatment are buddies to those just beginning it. Collaborate with Veteran Service Organizations. The Language of Disease and the Language of Health The medical informatics industry has lexicons of about 1 million terms describing the varieties of illness. The bookstore at a medical school is full of books about disease. The general public bookstore’s section on health and fitness, however, is wildly different. These books describe an entirely different activity. We don’t have a language for health. The industry uses a language of disease. Its diagnostic instruments focus on the disease state, not the health state. The epidemic of health requires a positive language to discuss and replicate health. The language of health must be able to deal with the notions of vitality, resilience, trust, mutuality, community, self-reliance, and other things far removed from the traditional medical nomenclature. The RealAge age reduction concept – to reduce a huge corpus of evidence-based medical information into a single value in the context of the individual – is a promising step in this direction. The personalization perspective is a profound shift in our notion of health care information systems. From the perspective of the individual, the medical informatics industry reflects almost exclusively the needs and goals of the enterprise. Nearly every health care organization will speak of “patient oriented” care, yet this is always in the context of “within our organization.” The patient is “captured.” The format, content, access privileges, storage, and retention of the information is the responsibility of that organization, with no control by the individual. The language of health would be based on a completely different foundation, driven by the concepts of personalization, community, mutuality, trust, and communication. The conditions for revolutionary rethinking of the health process are upon us, driven by the need for health care reform, the Internet, and the public’s distaste for the current system. The successful organization of the future will be the one which understands how to personalize these trends to the needs of the individual. 66 Report from “Epidemic of Health” Meeting81 Suppose good health habits and wellness could spread like measles or chickenpox? A group of medical, policy and technology professionals who believe this can happen gathered last month to plot the outlines for an “epidemic of health”—a sense of healthawareness and empowerment among individuals that would “infect” them and become more potent as the “infection” burgeons. The epidemic’s vector would be the World Wide Web and its tremendously powerful ability to transmit knowledge—and to let the user determine which knowledge is most useful to him or her. “Person-centered” is the desired symptomatology for this outbreak. The laboratory for seeding the epidemic would be the Veterans Health Administration, which constitutes the nation’s largest health care system and which already has engaged in some visionary forays into using technology to enhance individual access to information and to improve health status in the process. VHA would like to undertake additional pilot projects to foster an “epidemic of health,” deputy under secretary for health Dr. Thomas L. Garthwaite told the group which met here under the auspices of the Center for the Advancement of Health (CFAH). The CFAH is funded in part by the Nathan Cummings and the MacArthur foundations, advised Dr. S. Robert Levine, who heads CFAH’s initative on “Capturing a Promise of the Information Age: Person-Centered Health Care.” CFAH’s focus lies in the interaction between mental and physical states that can influence health status, the ultimate goal being to establish a scientific base that will infuse “person-centered care” into everyday life. “It’s a simple concept—that understanding the consequences of behavior can lead to better health,” Dr. Garthwaite observed. “Send us your ideas,” he urged members of the group. Dr. Michael Roizin of the University of Chicago emphasized that the key to improving health lies in the hands of individuals—not the medical profession. His intensely popular website has given proof to the value of this concept: RealAge uses the “tag” of lowering one’s “real age” through better lifestyle habits. Those who answer a series of carefully developed questions are given their “real” versus “chronological” ages, with advice on the steps that can be taken to become even “younger.” Each individual controls his or her own data and can erase it all at any time. A New Language Health status and the Internet are like ping pong balls and mousetraps, said Thomas Munnecke of Science Applications International Corp. (SAIC), one of the original developers of the DHCP. One ping pong ball on one mousetrap doesn’t accomplish anything when released, but a multitude of balls on a multitude of mousetraps lead to constant motion. “We are entering a new era of connectivity,” he said. “The traps are loaded and the balls are there, ready to fire.” 81 Nancy Tomich, Editor, US Medicine, reporting on the Epidemic of Health meeting in Washington, May 3, 1999 67 But to have this “wired” interaction occur successfully, there must be true communication, Munnecke cautioned. Too often authority replaces communication, with rigid standards and vocabulary terms piled on each other, the result being a complex system that thwarts rather than enables the accumulation of knowledge and exchange of ideas. The “sacred cow” of rigid standards needs to be “barbecued.” “The problem is that there is no language for the flow of ideas,” Munnecke said. ”We can’t view the system from the perspective of the individual.” The idea is not to “put a Web front-end on legacy systems,” but rather to build on the simplicity of the Web and its three uncomplicated standards—URL, HTTP and HTML—that operate within the constraint of IP, or Internet Protocol. The Web makes full use of the “law of increasing return,” Munnecke observed— “the more who have it, the more value it is to you.” The Web is not predictable or mechanistic, it is a medium: “It is the interactions that are important.” There is no “strategic plan” for the Web, “and it is impossible to define how big it is.” Bad things do happen on the Web—such as proliferation of sites devoted to pornography—simply because of the lack of control. The question, then, is how to make the Web useful for health in a positive way—to make it orderly and chaotic at the same time, or “chaordic?” “We must take a leadership role in developing a positive definition of health,” Munnecke said. So far, he said, the language of health care is too restrictive; it addresses only a small portion of the events and circumstances that influence health and wellbeing. For example, unemployment affects health status, but it is seen as an economic issue, separate from health. “There is no language for talking about healthy processes.” The Web has become ubiquitous, Munnecke observed, with URLs appearing on such unlikely places as jars of jam. “People expect to see things on the Web.” The Web offers mutuality. For example, he said, a buddy system for veterans could allow someone going through hip surgery to be mentored by someone who’s already been through a similar procedure. The simple fact that exposing water to sunlight could help reduce the staggering rate of childhood diarrhea in the Third World—but this knowledge must be communicated. “The question is, how can we trigger this?” Thirty per cent of all Internet use centers around health-related issues, pointed out John Kelly of Aetna/US Healthcare. “This is not a concept for the future; it’s a concept for today,” he said of the desire to use the Web to foster an “epidemic of health.” Importance Of Self-Interest In health care, mistrust stems from authority, said Heather Wood Ion chief executive officer of VNA in Orange County, Calif. Can this situation be “reframed,” and can that be done within the VHA structure? The issue, said Dr. Roizen, is to create self-interest—a phenomenon he has achieved with his RealAge program, his attempt to “move evidence-based medicine to the public.” The RealAge website is the second most widely used one on the Web; his book on “RealAge” leapt onto best-seller lists within weeks. 68 The idea for RealAge came to Dr. Roizen during a high school reunion: He noticed that some of his former classmates looked much older than others, yet all were the same chronological age. He developed a template of questions that can be used to calculate an individual’s “real age” on-line <http://www.realage.com>, assessing such factors as vitamin intake, cholesterol levels, smoking habits and use of seat belts. “People want to do interactive things on the Web,” Dr. Roizen emphasized. RealAge began its Web venture with nine servers; it now employs 69. When it debuted, it began logging 1 million e-mails an hour. “Buddy systems are important in making the transformational change to get healthy,” Dr. Roizen said. And he follows this dictum himself. He remains available by cell phone to his patients who want to stop smoking, for example, so he can help them through those difficult moments of craving nicotine. John Bartlett also knows the value of the buddy approach. His program in Georgia, DayOne, is a “life-management services package” that relies on individual responsibility and self-interest to help substance abusers, along with a similar level of responsibility on the part of center staff. The program operates independently of the insurance industry; those who participate must pay from their own pockets—a powerful self-motivator. “We knew insurance could not cover our services anyway.” “We wanted to change the rules of the game,” he said. “We recognized that a facilitative environment is needed to help people change behavior over time.” The goal of the program is to transition from “provider-directed to self-directed care.” DayOne centers are located in retail strip malls within one mile of a major retail mall, to fall within “normal driving patterns.” Television ads are employed to confer product recognition—to make the program “branded” and thus trusted. Rita Moya of the National Health Foundation said her organization has maintained a health information program since the early 1990s, the triggering factor being the Los Angeles riots. Many of those needing care in the aftermath were uninsured, “and we tried to help them with electronic access” to community services. But this program focused on transactions and did not achieve “our ultimate goal” of delivering “health,” she said. Her organization now is researching the “motivational aspect” of finding “health” on the Web. As part of its work, the National Health Foundation examined 144 popular Web sites but found that few deal with the preventive public health issues that relate to health status. Among its activities: building databases “from the ground up” using zip codes as the only identifiers—databases which can be used for public health studies. New Way Of Thinking “We’re in the midst of a fairly profound transformation,” Dr. Garthwaite said of the Veterans Health Administration, with “dramatic change” occurring over the past five years: More than half of hospital beds have been closed; about 400,000 more veterans have been seen by 20,000 fewer employees; more than 270 community-based outpatient clinics have been opened, and VHA has moved from a hospital system “designed to intervene in the last stages of illness” to one that is population-based, with performance measures linked to patient outcome. VHA’s outcome measures all equal or exceed those in the private sector, he noted, “in terms of our ability to do immunization, do mammograms, give aspirin and beta 69 blockers after heart attacks—a whole list of things we wouldn’t have done a few years ago.” At the same time, VHA is preparing to change its information technology system, moving from the Decentralized Hospital Computer Program (DHCP), which has “reached the limits of its possibilities,” to a collaborative system with other federal agencies: the G-CPR, or government computer-based patient record. Dr. Rob Kolodner, associate chief information officer for business enterprise solutions and technology in VHA, said the DHCP has proven a useful and valuable information system. “But now we need access to information beyond our boundaries,” he said. VHA also is launching an initiative to look at the earliest symptoms of disease, an exercise Dr. Garthwaite conducted mentally while attending a meeting on veterans home loan guarantees. Why would a veteran miss a home loan payment, when he or she obviously wanted to buy the home? “Is that the first early symptom of a disease, for which we would later see that individual in our health care system?” This in fact now is being studied, Dr. Garthwaite said: “I have some statisticians who are trying to merge the older home-loan default files with our later health care files.” While data allow these types of correlations, making such associations also requires a “different way of thinking,” he said. “If we can begin to the place where we think of not patients, but people, and what it is they’re doing out here that ends up with bad health down here, the patient will be better off. We’ll ultimately save a lot of money and improve a lot of lives.” Such correlations could be made in joint venture with the military, suggested Dr. Kolodner. “We could say, ‘what are the early flags’ And maybe farther along we could raise a slightly stronger flag, saying ‘press this button and we’ll get you help.’ This would be done anonymously, to keep the trust.” Through a variety of links on the Web, the individual could be presented with a broad range of information—broader than VA per se or even health care per se. Using Data Aetna/US Healthcare maintains a searchable database—and smaller subsets of data—on the 16 million “members” for whom it manages care, related Kelly. Employees have “real-time” access to the data and can use it to communicate with both providers and members. For example, if a patient with asthma must begin therapy with steroids, monitoring is put in place. Individual patients currently do not have access to the Aetna/US Healthcare database, though this is being explored. “We want to make the data available to the extent possible,” Kelly said. An epidemic of health must spring from existing systems, he advised, because they represent such a significant investment for most organizations: “You have to take that world as it as; you can’t force change.” The real issue is “finding ways to access the available data.” Dr. Levine said there appears to be a substantial amount that can be accomplished with legacy systems as the starting point. 70 An added challenge is presented by the “turmoil” in private-sector health care, Kelly observed, with patients changing plans frequently. Even small differentials in premiums can prompt individuals to move to a different insurer. Edgar Smith of Just Care has devised a “smart” credit card based in Web technology that can be used for health care. “The card allows the individual to be in control,” Dr. Levine pointed out. “It can be personalized, and it allows patients to go to other health plans.” It also facilitates correlation of various data— from pharmacies and clinical laboratories, for example. The card has been beta tested and now is being placed into use in Texas. Under consideration is “building in” the cost of a nurse call-in program, Smith said. Dr. Levine pointed out that the owner of the card “is the owner of a collaborative cyber environment” and controls the information it contains. Trust An Essential Factor Epidemics begin with small, simple conditions, noted Munnecke, and that is where the epidemic of health must begin. “Everybody wants the penthouse suite in the skyscraper; they don’t want to talk about the foundation.” There are several dimensions to consider in fostering an epidemic of health, he said: • The process of intervention—that is, the health care system’s providing treatment for the patient. “Clearly this is very important. If I were going in for brain tumor surgery, I’d want to make sure I had the best possible process.” • Collaborative space—the concept of mutuality and collaboration. “Part of this is people collaborating with each other independent of the enterprise, through support groups.” • Trust—the essential ingredient for making collaboration valuable. How can the individual be induced to voluntarily become exposed to the epidemic? “What we’ve found,” advised Dr. Roizen, “is you’ve got to make it personal and interactive. And you have to be honest with them.” If an individual wants information on magnetic therapy, for example, “you have to say we don’t have data on this yet. But you have to let them ask the question that is important to them.” “RealAge” attempts to build trust, he said, by allowing the individual complete control of the data he or she accesses: “They can put in any password, any e-mail address they want. If they want to kill their data, they can kill it....A key component is that you control the data, and you control who sees the data.” Moya noted that research has shown accuracy to be greater when an individual interacts with a computer rather than with another person. The perceived risk involved in revealing information must be taken into account, said Lt. Col. Mary Ann Morreale, USAF, MASC, director of the Military Health System Interagency Technology Sharing Program For example. she said, military personnel may find their careers linked to their health. In what may be an apocryphal story but one that is believed by at least some members of the Marine Corps, the perception exists that Marines who are temporarily injured cannot be deployed for three months and thus are ineligible for promotion. “If you’ve ever seen a Marine’s record, there is almost no record, because if you’re put on a profile for limited duty, you cannot be promoted during that time period,” a Marine colleague has asserted. 71 If indeed true, the same concern likely would hold true for firefighters and police, Lt. Col. Morreale suggested. A “key issue,” said Dr. Garthwaite, is to ensure that data are used to benefit the individual and not the organization or system. For example, VHA is trying to develop a patient report card that would provide information about health status. To let the patient control the data used to develop this report card would mean that VA “has to totally give it up.” “The model we’re talking about is letting go, and saying ‘yes, we have the data in our systems,’ but once we give it over, anything in addition that person puts into it is theirs. They choose whether to release it to us. It’s up to us to establish the trust that they will—but if they choose not to, that’s okay too.” “The more patients trust the enterprise, the more information they will give,” observed Munnecke. “The more honest they’ll be about their drinking habits, or their addictive habits.” Bartlett said he sees the basic issue to be whether ”the current enterprises that constitute the health care delivery system” should have a role in developing a personcentered system. “Obviously, the enterprise can devote the resources to it....By creating a culture and set of values and actions, step by step, that build trust over time,” a “chaordic” system results—one in which chaos and order are balanced. “You have to be willing to turn over control...People are very aware of the ramifications of information they share within social systems. People don’t trust their HMOs.” Trust comes from having total control oneself, emphasized Dr. Roizin: “I put in my own password; I put in my own name...It is totally patient controlled, and trust builds up. The value of the organization, I think, is to provide the health space—someplace to talk and gather the information in a secure way.” What likely will be needed, he said, is two sets of data, one of which contains data individuals are willing to give to an enterprise such as the VA, and the other of which contains entirely personal data that need not be shared with anyone. Physician-patient interaction is not going to “go away,” cautioned Dr. David Stevens, chief academic affiliations officer in VHA. “We need to look at how we change the culture of the clinicians to give more authority and power to the person sitting in front of him.” Dr. Levine suggested that a “third party” may be needed to “establish rules of evidence” for how information is gathered and organized, “so that there is some way, when individuals seek information, they can have a sense that it meets certain rules of evidence,’ and therefore can be judged and valued. “Trust is local and intimate,” said Ion, “and we will only build it over time, by choice.” 72 New Health and the New Economy82 [The telegraph] binds together by a vital cord all the nations of the earth. It is impossible that old prejudices and hostilities should longer exist, while such an instrument has been created for an exchange of thought between all the nations of the earth. Charles Briggs and Augustus Maverick, 1858 [It is] inconceivable that we should allow so great a possibility for service and for news and for entertainment and education [as radio] ... to be drowned in advertising chatter or used for commercial purposes. Herbert Hoover, 1922 Television drama of high caliber, produced by first-rate artists, will materially raise the level of dramatic taste of the American nation. David Sarnoff, 1941 Cable [television] will create great access to information; it will also greatly assist self-identity, democratic processes, educational environments, and community cohesion. Barry Schwartz, 1973 Our new ways of communicating will entertain as well as inform. More importantly, they will educate, promote democracy, and save lives. Al Gore, 1994 Our health, and our system for dealing with it, is perched on a cusp of radical change. The convergence of the Internet, the World Wide Web, and the “New Economy” will trigger a cascade of changes throughout the health field. Although each new technology is introduced with great expectations of utopian outcomes, these are not always realized. Good things do not necessarily happen from new technologies – they require constant vigilance. If we are to assure that the Internet and the new economy actually improve our health, we must act now rather than later. This requires a fundamental reexamination of the health process. This paper will discuss the health system triggered by the new economy as “new health.” It is a broader view than the “health care industry,” indeed, it argues that the industrial model of health is not the appropriate paradigm for dealing with our health issues. An industry, in the classical sense of the industrial revolution, is based on the production of goods or services based on the notion of scarcity. The oil industry extracts oil, adds value by refining and distributing it, and sells the resulting product according to the “law” of supply and demand. When person A buys a gallon of gas, it is a gallon depleted that person B can no longer use. There is a well-defined relationship between 82 Munnecke, Tom, prepared under contract for Business Enterprise Solutions and Technologies, Veterans Health Administration, Department of Veterans Affairs, October, 1999 73 providers and consumers. Economists can measure productivity; accountants can create the “bottom line” of each division, and managers can maximize profits and value for shareholders. Health is fundamentally different than oil, however. Person A’s getting healthier does not deprive person B of their health. In fact, one person’s getting healthier increases everyone else’s health. Someone who is able to avoid AIDS, Tuberculosis, Smallpox, Polio, sexually transmitted diseases, whooping cough, or a cold, makes everyone else a little bit healthier. The fewer drunk drivers there are, the safer we all are. Someone who has enough energy at the end of the day to volunteer for school, church, or civic activity, will make their community a little better. Healthy, well-adjusted families will reduce crime, vandalism, and substance abuse problems. The net effect is: the healthier you are, the healthier I become. Traditional market economies do not deal with this. Supply and demand economics are based on scarcity. If there is not a natural scarcity of a product, the scarcity is created through branding or barriers. The old health market creates barriers in order for the market mechanism to operate. Consider that an Internet health startup in Finland is able to operate everywhere in the world except United States and Canada. In order to turn health into an industry, it had to become a scarce commodity. Somehow, we had to introduce a barrier that would make it “productive” for someone to “produce” for the “consumer.” Hence, the health care industry. Health was the responsibility of “providers,” and people were placed in the passive role of “consuming” what the industry provided. New health is based on the infrastructure of the new economy. The old paradigms, metaphors, and notational systems for industrial era health care system are all subject to rethinking in the new economy. The New Economy There is evidence that a major shift in the global economy is taking place. This is largely driven by the rise of the Internet and the connectivity it provides: “Networks have existed in every economy. What’s different now is that networks, enhanced and multiplied by technology, penetrate our lives so deeply that “network” has become the central metaphor around which our thinking and our economy is organized. Unless we can understand the distinctive logic of networks, we can’t profit from the economic transformations now under way.”83 The distinctive logic of the network is a fundamental shift from traditional hierarchical perspectives. In a network economy, the more plentiful things become, the more valuable they become. The more people visit a web site, the more valuable it becomes, which in turn attracts more people. This is an inversion of the traditional supply and demand economics, in which value is created by scarcity. Tim Berners-Lee, the inventor of the web, was well aware of network thinking. He envisioned the web as a universal space for information, in which people could make their own connections: “In an extreme view, the world can be seen as only connections, 83 Kelly, Kevin, New Rules for the New Economy, Viking, 1998, p. 2 74 nothing else. We think of a dictionary as the repository of meaning, but it defines words only in terms of other words…what matters is the connections.”84 He saw the need for rapid, unlimited growth: “Philosophically, if the Web was to be a universal resource, it had to be able to grow in an unlimited way. Technically, if there was any centralized point of control, it would rapidly become a bottleneck that restricted the Web’s growth, and the Web would never scale up. Its being “out of control” was very important.”85 In order to create a system in which health is a universal resource we need to understand the dynamics of “out of control” systems. We need to understand how complex adaptive systems can start from a simple initial condition and evolve over time adapting to their environment. There were other systems similar in concept to the web, which failed because they did not deal with network economics. Ted Nelson proposed the Xanadu system in 1970’s, based on an ownership and payment system which created a barrier to entry. It was as if Amazon.com or E-bay tried to collect payment from the viewer every time they clicked on their site. Another system, Gopher, had such stringent licensing and intellectual property restrictions by the University of Minnesota that it was overtaken by the license-free WWW system. The three standards which initiated the web were the simple definitions for URLs, HTTP, and HTML. There were not computer science breakthroughs or fundamental discoveries. They were simply a common-sense approach to enable a very powerful vision. The power of the web comes from its universality and generality. Berners-Lee speaks of the web as an “exercise in generality.” Those looking for traditional hierarchical control structures find only a space, in constant flux, and highly dependent on the point of view of the observer. There is no “top” to the web, nor is there “one correct way” to use it. Kelly speaks of this shift: The new economy deals in wispy entities such as information, relationships, copyright, entertainment, securities, and derivatives. The U.S. economy is already demassifying, drifting towards these intangibles. The creations most in demand from the United States (those exported) lost 50% of their physical weight per dollar of value in only six years. The disembodied world of computers, entertainment, and telecommunications is now an industry larger than nay of the old giants of yore, such as construction, food products, or automobile manufacturing. This new information-based sector already occupies 15% of the total U.S. economy. 84 Berners-Lee, Tim, Weaving the Web, The Original Design and Ultimate Destiny of the World Wide Web, Harper San Francisco, 1999, p.12 85 ibid., p. 99 75 Yet digital bits, stock options, copyright, and brands have no economic shape. What is the unit of software: Floppy disks? Lines of code? Number of programs? …The dials on our economic dashboard have started spinning wildly, blinking and twittering as we head into new territory. It is possible that the gauges are all broken, but it is much more likely that the world is turning upside down.86 What are the units of health in this upside-down world of network economics? Health did not fit well into the old economics of supply and demand. Is it possible to conceive of a health system driven by network economics, in which everyone can get healthier, in which no one is in control? Whether or not we “approve” or the powers that be “manage,” the network economy is going to force massive changes in the system. Ten Rules for the New Economy Kelly proposes “10 radical strategies for a connected world.” 87 For the sake of discussion, this paper will discuss them in light of new health: 1. Embrace the Swarm: As power flows away from the center, the competitive advantage belongs to those who learn how to embrace decentralized points of control. 2. Increasing Returns: As the number of connections between people and things add up, the consequences of those connections multiply out even faster, so that initial successes are not limiting, but self-feeding. 3. Plenitude, not Scarcity. As manufacturing techniques perfect the art of making copies plentiful, value is carried by abundance, rather than scarcity, inverting traditional business propositions. 4. Follow the Free. As resource scarcity gives way to abundance, generosity begets wealth. Following the free rehearses the inevitable fall of prices, and takes advantage of the only true scarcity: human attention. 5. Feed the Web First: As networks entangle all commerce, a firm’s primary focus shifts from maximizing the firm’s value to maximizing the network’s value. Unless the net survives, the firm perishes. 6. Let Go at the Top. As innovation accelerates, abandoning the highly successful in order to escape from its eventual obsolescence becomes the most difficult and yet most essential task. 7. From Places to Spaces. As physical proximity (place) is replaced by multiple interactions with anything, anytime, anywhere (space), the opportunities for intermediaries, middlemen, and mid-size niches expand greatly. 8. No Harmony, all Flux. As turbulence and instability become the norm in business, the most effective survival stance is a constant but highly selective disruption that we call innovation. 9. Relationship Tech. As the soft trumps the hard, the most powerful technologies are those that enhance, amplify, extend, augment, distill, recall, expand, and develop soft relationships of all types. 86 87 Kelly, p. 3 Kelly, p. 161 76 10. Opportunities before Efficiencies. As fortunes are made by training machines ever more efficient, there is yet far greater wealth to be had by unleashing the inefficient discovery and creation of new opportunities. Embrace the Swarm “Swarm” is Kelly’s name for the dynamics of a large group of autonomous agents acting independently, yet accomplishing a common goal. A colony of ants or a flock of birds flying in formation exhibit collective behavior which transcends that of any single member of the swarm. Dumb parts, properly connected into a swarm, yield smart results. This is a shift from the past: “The atom is the icon of the 20th century. The atom whirls alone. It is the metaphor for individuality. But the atom is the past. The symbol for the next century is the net. The net has no center, no orbits, no certainty. It is an indefinite web of causes. The net is the archetype displayed to represent all circuits, all intelligence, all interdependence, all things economic, social, ecological, all communications, all democracy, all families, all large systems, almost all that we find interesting and important. Whereas the atom represents clean simplicity, the net channels messy complexity.”88 Health is a messy, complex issue. Attempts to simplify it into neatly categorized, independently measurable entities are notoriously difficult: “For example, after several meetings and unanimous consensus, expert’s [physician specialists] estimates of the effect of colon cancer screening on colon cancer mortality ranged from 5 to 95%. Fifty cardiovascular surgeons’ estimates of the probabilities of various risks associated with xenografts vs mechanical heart valves ranged from 0% to 50%. For one particular risk, the 10-year probability of valve failure with xenografts, the range of estimates was 3% to 95%… Virtually all of the current quality assurance and cost-containment mechanisms assume that there is not only “safety in numbers” but “accuracy in numbers.” In other words, if the decisions of the individual physicians cannot be trusted, the collective decisions or actions of a larger number of physicians can be trusted.”89 This kind of thinking leads to statistical aggregation and “one correct way” management styles. For example, the state of Oregon planned to revise their Medicaid program using a method based on a Quality of Well Being (QWB) scale. The scale defined 24 health or functional states, ranging from perfect health to death. Each QWB state was assigned a weight to reflect the quality of life associated that category. These scores and weights were then plugged into a formula. This leads to problems when trying to do arithmetic on these scores: 88 89 Kelly, p. 9 Eddy, David M., Clinical Decision Making, From Theory to Practice, Jones and Bartlett, 1996, p. 3,6 77 “To derive weights for the QWB states, Oregon citizens were asked to describe how different types of symptoms and health states would affect their quality of life as individuals. The form of the question was, “If you had [some collection of symptoms or limitations], how much would that decrease the quality of your life, on a scale of 0 (death) to 1 (perfect health). To say that living with symptoms in QWB state 8 (vomiting, fever, and chills) has a weight of .63 means that having these symptoms was judged to decrease the quality of an individual’s life by about .37, or about one third as much as death itself (which moves QWB from 1 to 0)…Thus, the score of 0.63 for category 8 would imply that, if the costs and durations of two treatments were the same, treating three people to prevent vomiting would be equivalent to treating one person to prevent death. Even if responders answered the original question accurately, they might not agree that the answer should be interpreted or used this way.”90 Swarms are non-linear: the whole is greater than the sum of the parts. Linear techniques which reduce complex systems into parts, and assume the whole is exactly equal to the parts are bound to fail – or at least be unable to cope with the difference between the whole and the sum of the parts. Increasing Returns The “fax effect” describes the dynamic of the growth of the fax machine. As each new fax machine was purchased, it increased the value of the existing base of fax machines. This “increasing returns” effect drove the fax market to ever-larger numbers of fax machines. This is a driver in much of the network economies. Web sites vie for “eyeballs,” the number of visitors to the site. The more “eyeballs,” the more valuable the site becomes. This positive feedback loop fuels the growth of the web, as more users and sites create ever more value for ever more users. Health can be envisioned as something subject to increasing returns. Everyone can become healthier, and in doing so, make everyone else healthier. The August 1999 Economist magazine issue said that the single greatest contribution to improving global health would be to get people to wash their hands before eating. This is not an expensive or particularly difficult global health problem. It illustrates increasing returns in the new health: the healthier we become by washing our hands, the less disease we communicate to others. The healthier everyone else and our communities become, the healthier each of us becomes. Plenitude, not Scarcity The new economy is driven by the notion of plenitude, not scarcity. There is no shortage of information on the web, and it is growing daily. Those seeking information are constrained by the quality of the search engines and their time to use them. Plenitude works to drive value, open up closed systems, and spins off immense numbers of activities. In a network economy, the more plentiful things become, the more valuable they become. 90 Eddy, p. 139 78 According to Kelly’s strategy, successful new economy participants will: 1. Touch as many nets as possible, to place their offerings in as many situations of increasing returns as possible. 2. Maximize the opportunities of others, allowing others to build their success. E-bay, for example, has opened up an entirely new market for home entrepreneurs to sell their goods globally instead of just local swap meets. 3. Avoid proprietary systems. Systems which have a barrier to entry will eventually open up or die, according to Kelly. Health can be driven by plenitude. The closed, proprietary systems of health care we have today are based on scarcity. Follow the Free The net rewards generosity, as the notions of increasing return and the economics of plenitude invert traditional supply and demand curves. In traditional economics, increasing demand would drive the price up. In new economics, increasing demand drives the price down. Ubiquity drives increasing returns on the network. Companies often find that it is in their own best interest to drive things to be ubiquitous by giving them away free. Much of the information available on the Internet is given away free, in the hopes of creating “increasing returns” for the future. How can the health care provider compete in this new economy? It will be an environment in which the network value of a provider is paramount – their connectivity to their customers. Why not give away their information and low cost screening activities as a way of creating additional trust and attention for future business? This brings up entirely new forms of value creation in health. Just as Reader’s Digest was the most widely read magazine in its heyday, and TV Guide was more profitable than the three major networks it guided viewers to, new forms of value creation will abound in the new economy. Feed the Web First The web is both the infrastructure and the role model for large-scale associative systems seeking the dynamics of increasing returns. Dramatically increasing communication speeds and lower cost terminals will make web access soon as ubiquitous as television access is today. “Bit by bit, the logic of the network will overtake every atom we deal with.” Already, the cost of electronics in a car ($728) is greater than that of steel ($675). Kelly describes a relentless progression towards web-based activities: 1. 2. 3. 4. 91 Increasing numbers of inert objects are animated by information networks. Once the inert is touched by a network, it obeys the rules of information. Networks don’t retreat, they tend to multiply into new territories. Eventually, all objects and transactions will be run by network logic.91 Kelly, p. 77 79 Much of health is information. It can be very expensive to create the first copy of the information, but succeeding copies are nearly free. For example, the first copy of a vaccine is very expensive, but immunization is one of the cheapest forms of health care. The relentless logic of the web would subject this information to the laws of increasing returns. This requires a new way of understanding the notion of health capital…those who increase the health capital of society would be rewarded for their efforts. Let Go at the Top An MIT economist wrote: “Firms are remarkably creative in defending their entrenched technologies, which often reach unimaginable heights of elegance in design and technical performance only when their demise is clearly predictable.” Those who have risen to the top of their market place have the most to lose from change; those attacking have little to lose, and everything to gain. Digital Equipment CEO Ken Olsen said during his peak that Unix was “snakeoil” and PCs were “toys.” After a long decline, his firm has since been acquired by Compaq, one of those “toy” manufacturers. Established Wall Street brokers did not want to lose their business to low cost online traders. Then start up companies brought out online trading services. They were a great success, and the established brokerages had no choice but to offer their own services. Amazon.com did not ask Barnes and Noble if it was a good idea to sell books online. Future successes in new health will likely come from small start up “attackers” at the “bottom” rather than established providers with a vested interest in maintaining their current operations, organizational culture, and ways of doing business. They are spending so much of their resources “integrating” themselves that a fast moving, relationship-driven association of competitors can offer lower cost, higher quality services. New health has to start from the individual and the bottom. From Places to Spaces As the network diminishes the notion geography, economies will be driven by “spaces” rather than “places.” Few people know or care where Amazon.com warehouses are located, or whether they have a warehouse or not. To them, the Amazon shopping experience, browsing among other reader’s comments and similar books is a space in which they feel comfortable. Spaces shift economics in several ways: 1. 2. 3. 4. A different kind of bigness Rampant clustering Peer authority Re-intermediation The web itself is a different kind of bigness: “What was often difficult for people to understand about the design [of the web] was that there was nothing else beyond URIs [URLs], HTTP, and HTML. There was no central computer “controlling” the web, no single network on which these protocols worked, not even an organization anywhere that “ran” the Web. The web was not a physical “thing” that 80 existed in a certain “place.” It was a “space” in which information could exist.”92 The restrictions of behavior in a place do not apply to that of a space. Linear value chains become adaptive value webs. All nodes are intermediaries, and network connections become valuable. It is possible to conceive of health occurring within a “space.”93 This notion is different from the traditional enterprise-centric viewpoint, which is derived from the point of view of an enterprise operating on an individual. The notion of a space allows an inversion of the perspective – the person is at the center, and providers are at the periphery. Personal Health Community The Personal Health Community (PHC) is an essential building block for creating a space for the health process for the benefit of the individual. Each individual’s PHC is under their personal control. They chose the members of the community with which they wish to interact, based on their personal health care interests, needs, and beliefs. Providers “connect to compete” and become part of as many PHCs as possible. Those who are the most trusted, and provide the best service are the ones who are selected. The PHC contains the individual’s data vault, which is a secure, trustworthy storage mechanism which holds their information in various zones. Zones are separately controllable by the individual. For example, allergies and special emergency instructions may be kept in publicly accessible zones, while family active medications may be kept in a more restricted zone, accessible only to the individual’s treatment team, pharmacists, optometrist, dentist, and chiropractor. Some genetic testing results may be zoned to be accessible only upon direct permission of the individual. The PHC is thus a mediator and tracker of the flow of information about an individual. The individual controls and has the ability to monitor these flows. Those who access information realize that they are accessing an individual’s PHC, and that their access is being tracked. The owner of the PHC is thus at the center of a health community of their own choosing. They are able to enlarge or scale down access to their information according to their personal preferences. For example, some Catholics may wish to allow their priest access to their medical records, others may not. Others may wish to share some information, but keep some private. These decisions are made at the individual level, not at the aggregate level of “All Catholic priests can/cannot see all Catholic patient information.” Similarly, different individuals have different health beliefs. Some have great aversion to taking drugs. Some may believe in acupuncture, others homeopathy. There is no one correct definition of the proper health community; it is an interaction between individuals, their personal situation, environment, belief system, financial status, family, community, and a host of other individual parameters. There is no “one correct way” to deal with an individual’s health. The PHC supports this notion by allowing individuals to grow this community according to their own interest. For example, suppose someone comes down with 92 93 Berners-Lee, p. 36 Contact the author for a January, 1998 paper entitled HealthSpace. 81 influenza, and decides to browse the online groups for others with the same symptoms. They find that most people complain of 48 hrs of extreme fatigue, mild fever, and coughing, after which they have about 2 weeks of a cough. Interacting with the group, they find that the most effective treatment for the cough is to take a hot shower, directing the water on their chest. Just having others to talk to and share complaints about the illness is a function of the community. The convergence of the group’s lessons learned from everyone else’s trials and tribulations provides a valuable health service, and an example of increasing returns of new health. Note the difference between this and the traditional doctor’s office visit. After spending time in the waiting room with a depressed immune system, exposed to other’s ailments, the patient has a few minute “snapshot” interaction with the physician. The physician may see many patients with the same ailment, but only sees feedback from those whose treatments fail. Someone who successfully battles the problem on their own will not return to share their success story. Therefore, the system replicates failure, not success. The online community, because it is interactive, however, will share their success stories with each other. Perhaps some of these are “old wives tales,” and some are derived from believers on the fringes of the alternative medicine frontiers. The individual is responsible for considering the source of the information. The individual is responsible for understanding and dealing with multiple streams of health information. The notion of trust becomes paramount. Relationship Tech The central economic imperative of the network economy is to amplify relationships, a tremendous shift from the notion of the industrial era’s imperative to increase productivity. Links between objects on the network define the network. Producing and consuming fuse into a single verb, prosuming, coined by Alvin Toffler in 1970. Individuals produce health for others when they fight off an infectious disease, for example. Relationships which require two parties to invest in each other increase in value twice as fast as those in which only one side invests. Telephone companies sell to “friends of friends”, creating circles of relationships which increase their customer base. In the same way, new health relationships can drive an ever-expanding base of activity. The more people trust a given provider, the more valuable it becomes. Trust in the new health and new economy is a critical issue: “Trust is a peculiar quantity. It can’t be bought. It can’t be downloaded. It can’t be instant – a startling fact in an instant culture. It can only accumulate very slowly, over multiple iterations. But it can disappear in a blink….Trust is tough because it is always linked to vulnerability, conflict, and ambiguity. For managers steeped in rationalism, hierarchies, rule-based decision making, and authority based on titles, this triad of vulnerability, conflict, and ambiguity threatens a loss of control.”94 94 Kelly, p. 133 82 Trust in the current health care system is a critical issue, which is eroding rapidly as hierarchical, command, and control management structures descend on the field. Opportunities before Efficiencies The industrial era’s focus on productivity as a metric was inspired by efficiency. It is difficult to argue against efficiency; one would certainly not want to advocate a system which was inefficient. However, like the Oregon system that equated three vomiting people to one death, our metrics for efficiency miss critical needs. To measure productivity, we need uniform outputs. In order to unify outputs, we need to reduce complex interactions into snapshots of simple, measurable quantities. This is the basic reasoning behind the transaction. We have 500 years of developing accounting systems based on the aggregation, categorization, and summation of transactions. The transaction, however, has become the anchor that is sinking the very ship it is attempting to stabilize. We need a new form of understanding adaptive systems, ones that will deal with the messy vagaries and complexities of health. “Until Charles Darwin’s discovery of evolution, life was surveyed in the present tense. Animals were probed to see how their innards worked, plants dissected for useful magical potions, the creatures of the sea investigated for their strange lifestyles. Biology was about how living organisms thrived day to day. Darwin forever transformed our understanding of life by insisting that life didn’t make sense without the framework of its billion year-old evolution. Darwin proved that even if all we wanted to know was how to cure dysentery in pigs…we had to keep in mind the slow, but commanding dynamics of life’s evolution over the very long term.”95 In a similar way, we can think of the old health industry as thinking of health in only the present tense. New health must understand health as a long term, adaptive, constantly changing interaction between huge numbers of people. 95 Kelly, p. 141 83 From Enterprise to Person-Centric Health Information Systems96 A New Perspective of Health and Information Albert Einstein imagined riding a beam of light, and discovered relativity. Jonas Salk imagined being a poliovirus, and discovered a vaccine. Both of these inverted perspectives triggered great discoveries. A new inversion of perspective in health is emerging, dealing with the shift from enterprise-centric to person-centric information systems: “The patient is the center of the health care universe, not the hospital. Information systems of the future have to be built around the patient - what his or her needs are, what services he or she receives, and what are the outcomes of our interventions and other efforts. We have to be able to track all these things across geography and across time. They will have to be unlinked to any specific organizational setting or geographical setting. That will require a paradigm shift in how we view our technology in the future.”97 To date, computers and information systems in health have been dominated by the organizations delivering health care. They put their enterprise at the center, with patients at the periphery. The needs and survival of the enterprise were driving factors in the evolution of the system, the type of information collected, and the use of that information. With the advent of mass interactive communication technology such as the Internet, we now have an infrastructure upon which to rethink the role of health and information. The individual can be the center of their private health universe. Within this universe, enterprises will compete by personalizing their services to their customers, rather than integrating their internal operations. A key component to this new model of health information is the notion of each person having their own private information space, controllable by them, which holds their health information. Those who need access to their health information are able to access this information in a secure manner that is mediated and tracked by the software under the control of the individual. The mechanism, called Health e-Vault, is a radical shift from the traditional approach to the electronic medical record: 1. It is designed around the individual, not the health care provider. 2. It assumes that over the life of the individual, there will be a large number of providers, suppliers, and other associations involved with the individual’s health. These will not be physically co-located. 3. It assumes that information formats will be constantly changing, and that there will not be any “one correct way” to record health information. 4. It brings issues of trust, confidentiality, ownership, and access to health information to the forefront, making them critical success factors, rather than side effects of enterprise transaction processing. 96 Munnecke, Tom, prepared for VHA , April 1999 97 Kizer, Kenneth, "Forms in the Fog: Information Management in the New VA", speech to VA Information Technology Conference, May 19, 1997, Austin, TX 84 5. It treats health care as only one extreme of the health spectrum. The “normal” state of the individual is assumed to not be engaged in disease-based activities. It supports and enhances the role of communications within a trusted community of interest as a key contributor to the health of the individual. This paper uses the term “person” rather than “patient” for several reasons: 1. The word “patient” implies a disease state and a provider who is treating it in a health care setting. Ideally, the person would not be in the disease state in the first place. 2. The goal of the system is to keep the person from becoming a patient, to live a healthy life independent of the disease process as long as possible. Similarly, it uses the term “health” rather than “health care” to shift the focus on the health process of the individual. Health care is but one portion of the health process. The Exploding Complexity Enterprise-Centric Information Systems Health informatics has been attempting to solve the health information problem for the past 3 decades. It has been working from the perspective of the enterprise, attempting to integrate the divergent sources of information into meaningful collections maintained by the enterprise. The widespread automated, online health information system, however, is as elusive today as it has been for the past 30 years. The industry, medical technology, computer technology, and medical knowledge are all changing faster than our integrated information technology has been able to cope. Nomenclatures, coding schemes, government regulations, and payer needs have all expanded rapidly. This has lead to explosive complexity that is rarely fully realized by anyone dealing with only a part of the problem. Each sees their component as relatively simple, but is constrained due to “lack of integration” with the rest of the system. A health care system is simply too complex and too dynamic to create a single, static definition of how information will flow. In fact, it is impossible to define the components of the system in a single, static definition. These components will vary by patient, by time, and by context of care. There is no “One Correct Way” to deal with health information. From a complexity science perspective, the “integration crunch” is the core of the problem, not a path to the solution. The answer to the search for a viable health information system lies in accepting the divergent and constantly changing nature of health information, rather than attempting to force a single enterprise-centric perspective on the field.98 Whether or not the industry will soon solve its integration crunch dilemma is a matter beyond the scope of this paper. This paper discusses an alternative – the inverted perspective – to design the information system from the point of view of the individual. 98 To illustrate the changing nature of health information: at the time of George Washington it was common to use leaches. This practice was later abandoned as our understanding of medicine improved. Today, it has been revived in a new form, as sterile leaches are used during microsurgery of the hand in order to diminish the effects of swelling. The discovery of penicillin from bread mould was also a radical transformation in our understanding of the health process. 85 There are many differences between enterprise- and person-centric health information systems. The enterprise sees the person as an object to be acted upon, whereas the person sees the health care enterprise as only one piece of a larger puzzle: “Health care providers typically define problems related to diagnosis, poor compliance with treatment regimens or continuing unhealthy behaviors, such as smoking or lack of exercise. Patients, however, are more likely to define problems of pain and other symptoms, their inability to function as they once did, emotional distress, difficulty carrying out prescribed regimens or lifestyle changes or fear of unpredictable consequences of the illness.”99 In other words, the enterprise is solving one problem while the patients perceive another. The health care industry is largely driven by the survival needs of the organizations that comprise it. Although nearly every health care enterprise will speak of “patient centered” thinking, there is an implicit, “within our enterprise” which must be inserted in front of this phrase. These different views can be contrasted as follows: Issue Purpose Context Trust Organization Typical activity Enterprise-centric system Survival of the enterprise What is necessary for the survival and growth of the organization within its stated goals? Individual must trust entire system Integrated around operating units/functions within the organization Episodes of intervention Continuity of care Information System Management policies and workflow Tied to organization chart Authority Single and management chain within the organization Policies, regulations, management chains Control Person-centric system Survival of the individual What improves the health of the individual? Individual builds trust in community of interest, trusted third party for holding databases Associated with many different and constantly changing set of providers and sources of information Adopting healthy behavior, adjusting to injury, self-management, recovery, fitness, compliance with providers of health care Concerned people and agents acting on behalf of the individual Tied to context of person’s needs, computer literacy and virtual community The individual The individual, within constraints provided by regulation; community and social standards 99 From web page of Center for the Advancement of Health, “What we do”, “Living with Chronic Ilness” “Living with Chronic Illness, When Doctors and Patients work together” 86 The person-centric model may threaten stakeholders in the enterprise model, because it displaces them from the center of the health care universe. A trillion dollar industry does not change easily. The patient-centric model may appear today to be too simplistic and not powerful enough to compete with the established industry. In the 1980’s, Digital Equipment Corporation was a dominant force in the computer industry. Their VAX/VMS computer system was immensely as the center of its own universe. They saw little reason to change. Ken Olsen, CEO, denounced PCs as “toys” and Unix as “snakeoil.” A decade later, his company was purchased by Compaq, one of those “toy” computer manufacturers. What appears to be simple and “toy-like” in its early stages of development can hide tremendous power as it matures. Industry after industry, such as retailing, investment services, banking, and others are all discovering that their established models are being dramatically changed by the Internet and the Web. These changes come from the young upstart “attackers” rather than the established “defenders” of the current model. It was the upstart Amazon.com, not the established Barnes and Noble, who created the online book sales market. A New Way of Coping with Complexity Recent events and advances in information technology and complexity theory point to new ways with which to deal with complex adaptive systems. Systems can grow organically from simple beginnings, rather than being built from complex requirements. VISA International founder and initial CEO Dee Hock named this “chaordic.”100 In this model, complex adaptive systems grow from simple beginnings, increasing in complexity as a result of interaction with their environment. Thus complexity “grows” evolutionarily rather than being “built” mechanically. Systems at this level of complexity are constantly changing and evolving. They are in a state of “perpetual novelty,” which are not necessarily predictable. We cannot understand them according to traditional mechanical or engineering terms, but must rather seek to understand and control the environment in which they operate. The World Wide Web is a system which grew from simple initial conditions to become a major transformational force in the world today. The features that shaped the web were: 1. Simple Initial Conditions – the “primordial soup” from which the system emerged. For the web it was three simple definitions: the Uniform Resource Locator (URL), Hypertext Markup Language (HTML), and Hypertext Transport Protocol (HTTP). The simplicity of these initial conditions 2. Constraints – the boundaries outside of which the web could not stray. In the case of the initial web, this constraint was the Internet Protocol (IP). 3. Selection Criteria – the criteria by which success was replicated in the emerging web world. For the web, this criterion is attention. Web pages to which people pay attention survive, while those that are ignored die off. 100 See: The Trillion Dollar Vision of Dee Hock” at http://www.fastcompany.com/online/05/deehock.html 87 Systems growing according to the process will appear to be somewhat chaotic and disordered at first. Over time, order appears from this apparently chaotic “primordial soup.” These features are emergent properties of the system; they were not designed into the web by a body of authoritative experts. Today, we have search engines, virtual communities, and electronic commerce of far greater sophistication than was imaginable in pre-web days. Authoritative strategic planning does not control the future growth of the Internet; an evolutionary process drives it. Health e-Vault as a Starting Point A network company advertises, “In the age of the network, there is no ‘there.’” This creates a need for a notion of “here” for an individual’s health information. Health e-Vault is a portion of this larger vision of a person-centered view of health. It is a convergence of many forces: 1. Patient Empowerment. The notion that individuals are responsible for their own health changes the need for information to the individual.101 2. The Internet. This phenomenon is creating a much more “connected” society, providing an infrastructure in which people have much greater access to information. At the same time, it has created a much greater need for privacy and confidentiality on the Internet. 3. Health Care Reform. The need for portability and protection of health care information has created a need for a mechanism to provide health information to a variety of providers. 4. Complexity of health care. Individuals do not get all of their health care from a single institution. In addition to a primary care physician, they may use dentists, optometrists, chiropractors, specialists, counselors and others who are not part of a single enterprise. They may belong to support groups, or rely on family or community resources. The health e-vault is a necessary initial condition that reflects the shift to personcentered health. One vision of this person-centered system was developed by Dr. S. Robert Levine and others: Vision: To capture a promise of the information age, we envision a universally accessible system which can, through a variety of means, help direct individuals and families to the health information and resources they want and need to become full partners in promoting their health and achieving positive outcomes when ill. This system would link to a broad network of health resources through which all parties can share, in confidence, insight, expertise and knowledge, for the purpose of enhancing the health of individuals, families and communities, and improving the quality of our health care system. 101 For example, the National Library of Medicine recently discovered that one third of their Medline information system searches were done by the public, for their personal health needs. 88 Assumptions: 1. Individuals must be active partners in maintaining and restoring health, and caring for themselves and family members. 2. Individuals need assistance with health, developmental and life cycle crises/concerns. Guiding Principles: 1. Good health is in large part a function of the assumption of the responsibility for health by the individual. 2. Individuals, parents and family members are experts in the health of themselves and families. In order to utilize this expertise they must have access to useful information and willing partners in the health profession and the community at large. 3. Making better decisions requires access to information which is trustworthy, comprehensible, valuable and personalized. It must respond to a specific interest, concern, or problem, and must reinforce specific actions which, over time, may be taken to solve these problems, maintain health and promote well-being. 4. Focus must be on information exchange, with an emphasis on sharing of experience, insight, expertise, and knowledge to enhance self-efficacy, support health decision-making, and reinforce positive actions (on the part of individuals, families, professionals, plans and policy makers). 5. An individual (or family) who is enabled to make better decisions in his or her (or family's) interest can improve health and moderate costs. 6. The questions posed, information shared, and outcomes of specific actions should continually influence the design of the system and contribute to improving the quality of health care and practice of medicine.102 Access and Health Literacy Not all patients can read. Those who cannot face even more difficulties in dealing with the health care system: The healthcare system in the United States is facing a recipe for disaster. There is no more vulnerable population in this country than people who don’t read. This group has the worst health, the least knowledge of healthpromoting behaviors, and the fewest socio-economic resources to deal with those problems… our preliminary analysis shows that patients with inadequate literacy skills have a 50% increased risk of hospitalization, compared with patients who had adequate literacy skills…we can only speculate on the causes of excessive hospitalizations in this vulnerable population. Less knowledge of self-care options, worse general health 102 Levine, S. Robert and others, Progressive Policy Institute, Family Reunion 7 – Families and Health, Spring 1998 89 behaviors, and less ability to negotiate today’s complex healthcare system may all be major factors in the equation… About 36 million people are eligible for Medicare in the United States…16 million [of the elderly] are functionally illiterate. The average hospitalization cost per person per year for Medicare patients is $2,262…one might assume that a 25% to 50% increase in the cost of hospitalizations for Medicare patients with inadequate literacy skills. If we accept these assumptions, increased hospitalization costs directly attributable to inadequate health literacy could total $8 to $15 billion per year.103 One way of addressing this problem is to use interactive video technology. Information could be communicated in short video clips, rather than just printed instructions. Instead of viewing an active medication list, the individual could view videos of the drugs, with spoken instructions. The information of the Health e-Vault could be communicated with video, including video mail. The Role of Trust A critical component of the vault is the notion of trust. Computers and communications have triggered massive changes in our understanding of “the system,” and the information age is leading to revolutionary changes in control and authority in our society. Information is bought and sold as a commodity. We’ve moved from “Knowledge is power” to “Access to information is power.” Access to health information by the consumer is rapidly growing. An individual with a rare disease may have much more time and energy to research the problem than a physician allotted 12 minutes per patient. Patients offer a tremendous amount of information to their physician; the bargain is that the physician is expected to use that information for their benefit. However, as we weave an ever-growing web of interlocking financial, social, economic, and personal issues to health information, it is no longer possible to allow for this web to be controlled by “the system.” Each individual has unique needs and concerns, there is no “one correct way” to decide who is privileged to see what information. Dr. Denise Nagel of the National Coalition for Patients Rights worried that the current system is turning the doctor’s office into fishbowl instead of a safe harbor. The goal of the new system is to provide that private room in cyberspace. A trusted third party mediates access to an individual’s health information outside of the source institutions. Access to an individual’s information is under the control and visibility of that individual. Information may be collected into zones, which contain independent areas with separate access privileges and communities of interest. For example, Mr. Smith may want to share his active medication list with his primary physician, pharmacy A, optometrist, dentist, and chiropractor. One day while picking up a prescription, he overheard two pharmacists gossiping about a customer, and realized that they may someday talk about his prescription the same way. He decided to move to pharmacy B, and terminated pharmacy A’s access to his account. Pharmacy A still has their own internal records, but they will have not access to his broader records. Baker, David W. “The Impact of Health Literacy on Patient’s Overall Health and Their Use of Healthcare Services,” in the Procedings of “Health Literacy, A National Conference”, June 1997, sponsored by Center for Health Care Strategies, Inc. 103 90 His daughter has been diagnosed with a rare disease, and he searches the Internet for information. He finds an on line support group for this particular disease, who have formed a very active community of those afflicted with this disease. He finds a researcher, Dr. Jones, who is interested in his daughter’s case. After checking with Dr. Jones HealthSpace seal to determine that he is from a recognized university, John decides to admit Dr. Jones to his daughter’s account. 91 The World-Wide Web and the Demise of the Clockwork Universe.104 300 years ago, Newton, Laplace, and Descartes introduced a revolution in scientific thinking: with sufficiently precise understanding of initial conditions, the future could be predicted by applying a simple set of natural laws. Although this “clockwork universe” paradigm has long since been discredited by physicists, its intellectual descendants still haunt our institutions, bureaucracies, economies, universities, software development methodologies, and general zeitgeist. If only our policies and procedures, economic measures, university education, software metrics, and social indicators were more precise, we could apply a few simple “natural laws” and predict the future.... The scientific revolution of the past 300 years has undeniably yielded many tangible benefits. However, from many viewpoints, the clockwork universe mindset is proving insufficient to meet the real-world needs and expectations. We have learned from chaos theory that we cannot simple collect ever more precise initial conditions to predict the behavior of a system. We have learned from software engineering efforts that no matter how hard we try to establish the perfect initial conditions for software development (requirements) that we cannot generate a smooth, laminar flow software development process. There are many indicators which indicate that the reductionistic frenzy which has driven the lust for precision in our times is dissipating. Chaos theory, non linear dynamics, complex adaptive systems, genetic algorithms, artificial life, virtual reality, complexity theory, simulation, emergent computation, and fuzzy set theory are but a few of the disciplines affecting this. Rather than seeing the world as a set of complex initial conditions and simple laws, this new world view sees the things in a much more adaptive, “organic” manner. Systems begin with a relatively simple initial condition: a primordial soup, so to speak. They then evolve over time according to rules of selection and fitness. The world is not necessarily so deterministic. Positive feedback loops create unpredictable emergent properties. Autocatalytic organizations emerge which appear to violate the rules of entropy: they spontaneously exhibit increasing complexity. This paper discusses the problem of managing a large scale enterprise-wide information system. It builds on the technology embedded in the World Wide Web (WWW), complex adaptive systems, and object-oriented technologies to provide a framework within which an enterprise may construct an adaptive, evolutionary system which meets its needs in a cost effective manner. The traditional “clockwork universe” view of the world which was advanced by Newton and Laplace was based on the execution of a few simple laws (e.g., F=MA), starting from complex initial conditions (the position and momenta of all particles in the universe). Although physicists gave up on this idea at the time of Heisenberg, its analog 104 Munnecke, Tom, Presented at the Second Annual Conference on Mosaic and the World Wide Web Chicago, October, 1994 92 has carried forth in many other areas of thought. This “divide and conquer” mindset has lead us to divide and conquere organizations in economics, other sciences, education, medicine, and information technologies, as well as other places. Computer science has been subject to this kind of thinking, which has resulted in many different levels of reductionistic thinking: hierarchical decomposition, structured analysis and programming, various systems engineering approaches, etc. These approaches work in some domains which can be characterized as having complex initial conditions (expressed as requirements), executed with simple laws (the variants of structured programming). We “normalize” our data by structuring it into densely packed rectangular tables; data which doesn’t fit these rigid conditions are considered “unnormalized”, which is somewhat akin to the pope calling all people not in his church “non-catholics.” Indeed, the prefix “hier” means sacred or holy. Hierarchical decomposition of systems into functional components has become the sacred quest of today’s computer systems architects. The model presented in this paper presents a radically different view of the information system. It begins with simple initial conditions: as simple as possible, and then allows the system to evolve as a complex adaptive system which is adapting to its environment. Hollandidescribes these classes of systems: Many systems of high interest to humankind — economics, political organizations, games, ecologies, the central nervous system, developing organisms, biological evolution, etc. — rarely, if ever, “settle down” to some repetitive or other easily described pattern. Such systems are intrinsically dynamic (When they settle down they are “dead” or uninteresting) far from a global optimum (There is always room for further improvement, though the system may perform quite well in a comparative sense.) continually adapting to new circumstances (The strategies or structures that determine the system’s interactions continually change, often with accompanying improvements in performance... A brief inspection shows that all the systems mentioned involve a large number of “agents” adapting to each other in a complex network of local, nonlinear interactions. It is convenient to label these systems as adaptive nonlinear networks (ANN’s hereafter)....How does an ANN adapt to a perpetually novel environment that continually offers opportunities for further improvement? Three interacting subsystems must be defined in order to pursue an answer to this question: (1) the environment in which the system acts, (2) the structures that generate the system’s actions, and (3) the mechanisms that progressively adapt the system’s structures to the environment. Adaptation in Information Systems One can argue the case that adaptation is one of the critical roles in information systems.ii Many of the common activities associated with information systems can be considered different manifestations of the same property: adaptability: 93 Adaptability over: Is called: Time Sites Users Operating Systems, Hardware Changing Requirements (environment) Internal Changes Data Storage Techniques Maintenance Portability Security “Open systems” Flexibility Configuration Management Data Independence Thus, the bulk of the expense of traditional information systems can seen to be the cost of adaptation. In this paper we will call these systems manually adaptive: each instance of adaptation is handled via special intervention by humans. Entire departments in organizations are dedicated to this function. Given that their very existence is based on their manual adaptation of traditional systems, it is unlikely that self-adapting systems will emerge from within them. It is much like expecting to get out of hole by digging it deeper. Linearity and Nonlinearity Traditional information systems also tended to be linear. We started with a thorough set of requirements, from which we derived specifications which drove the programming. Programs were unit tested, system tested, and then delivered as a complete system. The system was then turned over to maintenance processing. These systems flowed from one stage to another, sometimes called the waterfall approach. Campbelliiidiscusses linearity: Putting it naively, [in linear systems] one breaks the problem into many small pieces, then adds the separate solutions to get the solution to the whole problem. In contrast, two solutions of a nonlinear equation cannot be added together to form another solution...Thus, one must consider a nonlinear problem in toto; one cannot—at least not obviously—break the problem into small subproblems and add their solutions. It is therefore not surprising that no general analytic approach exists for solving typical nonlinear equations [italics added] For instance, when water flows through a pipe at low velocity, its motion is laminar and is characteristic of linear behavior: regular, predictable, and describable in simple analytic mathematical terms. However, when the velocity exceeds a critical value, the motion becomes turbulent, with localized eddies moving in a complicated, irregular, and erratic way that typifies nonlinear behavior. By reflecting on this, we can isolate at least three characteristics that distinguish linear and nonlinear physical phenomena. First, the motion itself is qualitatively different. Linear systems typically show smooth, regular motion in space and time that can be described in terms of well behaved 94 functions. Nonlinear systems, however, often show transitions from smooth motion to chaotic, erratic, or, as we shall see later, even apparently random behavior... Second, the response of a linear system to small changes in its parameters or to external stimulation is usually smooth and in direct proportion to the stimulation. But for nonlinear systems, a small change in the parameters can produce an enormous qualitative difference in the motion... Third, a localized “lump” or pulse, in a linear system will normally decay by spreading out as time progresses...In contrast, nonlinear systems can have highly coherent, stable localized structures—such as eddies in turbulent flow— that persist either for long times or, in some idealized mathematical models, for all time. This remarkable order reflected by these persistent, coherent structures stands in sharp contrast to the irregular, erratic motion that they themselves can undergo. Perhaps Frederick Brooks summarized this most succinctly: “nine women can’t make a baby in one month.”iv Countless information systems have been planned as the smooth, laminar flow of subprojects down the waterfall of systems implementation, only to discover turbulence, eddies, and erratic responses to small changes in requirements. These hallmarks of nonlinear systems are typically met with great dismay and generate a response of renewed efforts to force the system to a linear flow with greater levels of precision, adherence to the processes and structures which failed in the first place. The “divide and conquer” linear thought process has assumed that one can decompose a system into pieces, program each piece, and then put them back together again to make a whole. But this is not the case with nonlinear systems. Just like Humpty Dumpty, things which are broken into pieces cannot necessarily be reassembled into a whole. Another problem comes into play with hierarchical decomposition: point of view. The “hier” in hierarchical reflects the authoritative point of view from which the problem is decomposed. This point of view is typically a department manager, whose function is being automated by the computer. As all the departments in an organization are automated, these points of view are encrusted into “stovepipe” systems, each programmed to the needs of the departments. Eventually, there is an initiative to have an “integrated” system, which somehow interfaces all of these divergent points of view. Ironically, this is typically just another point of view, and adds to the confusion, rather than solving the problem.v One may as well try to pick up several fallen Humptys simultaneously. An analogy to the problem might be to ask each of the department heads to create an outline of their organization’s behavior as they see it. The top left hand corner of each outline represents the point of view of the manager. Managers may start their outlines with the president, the customer, a product, a function, geographic location, chart of accounts, or other aspect of the organization. There is no right or wrong outline to their views; they are realistic representations of the world as they see it. Now, suppose you were asked to “integrate” all these divergent outlines of the organization. “We are a single, integrated organization,” you are told, and your job is to weed out the duplications and come up with the one true outline of the organization. You are faced with an impossible task. The organization from the point of view of the 95 customer service representative is different from the point of view of the accountant. But if you try to put “customer service” and “accounting” as two subheadings under “company,” you end up with much duplication. If you try to interleave the outlines, selecting sections from each, you become frustrated that you can’t take things out of context from one outline and simply insert them into another. As the number of outlines (decomposition points of view) increases, the problem becomes geometrically more difficult. Yet this is the state of many of our corporate information systems today, The information systems industry has been butting its head against this wall for 25 years, so much that it is now an ingrained behavior. So much so that experienced managers seek out the wall, place their head against it, and then complain about how hard it is to get any forward motion. Complex Initial Conditions, Simple Execution At the core of the traditional approach is the assumption that someone can come up with a consistent set of requirements, which can then be decomposed into specifications and linear thought processes. The system is really what is contained in the documentation or contract specifications. People go to great lengths to insure that the requirements are exactly what the user wants. Requirements become an entity unto themselves, a focal point of litigious contention in contract work. Systems analysts assume that people who have never seen the system operate can examine paper definitions of the system and comprehend the operation of the system in their setting. Design methodologies assume that there is a single overiding point of view which drives the entire system. Most information systems don’t conform to this simplistic linear model. It may be impossible to elicit the requirements of a system sufficient to produce specifications. Users may not know what they want until they see it. External forces such as governmental regulations may provide the small change which generates enormous change in the system behavior. Once the system is installed, it may influence the users’ behavior in such a way as to invalidate some of the requirements. The development process may take so long that the organization changes, markets change, or more pressing priorities arise. All in all, information systems development is a very turbulent, unpredictable process, no matter how hard we try to linearize it. WWW is an Example of a Complex Adaptive Information System. The WWW and the Internet are outstanding counterexamples to this. Over the past 25 years, the Internet has grown at an amazing rate; no one knows exactly how large it is or how much traffic it really carries. The Internet was not programmed according to specifications derived from requirements; it evolved. The Internet Engineering Task Force (IETF) works from a distinctly nonlinear motto: “rough consensus, running code, vi ” which is a concise statement of the fitness function for survival of new ideas on the Internet. The Internet clearly conforms to Holland’s description of complex systems: intrinsically dynamic, far from a global optimum, and continually adapting to new circumstances. How is it that the Internet continues to thrive and spontaneously produce new emergent systems such as the World Wide Web and Mosaic? The Internet is surely one 96 of the most massive intellectual adventures of our century, but how can this massive, complex system survive without central authority and control? What accounts for this vitality? The Internet cannot be explained in terms of linear concepts. The whole is greater than the sum of its parts. One cannot study the TCP/IP standard and understand the Internet’s behavior any more than one can study an ant and understand the ant colony’s behavior. The Internet must be understood in nonlinear, evolutionary terms. It is an organic process: successful ideas are replicated; unsuccessful ones die away. One model might be to consider the Internet to be one continuous usability test. Modifications which are usable (measured by the fact that they are used) propogate and prosper on the net. These changes, in the model of Jonas Salk, are “morphic.”vii Changes which absorb more resources than they produce are “entropic” and soon disappear from the Internet landscape. Designing Complex Adaptive Information Systems Although it is easy to look back and understand the success of the Internet over the years, it is somewhat more difficult to look ahead and plan systems with the same propensity to spawn emergent properties. First and foremost, however, is the need to consider the nonlinear aspects of the system. A cookbook for this might read: Minimize requirements. Your users do not know what they want until they see it. They can’t tell you in advance what they want. Provide the minimum set of requirements to define the “primordial soup” from which the system will evolve. The system is its own definition. The requirements which can be reduced to linear paper format are not the system. A nonlinear system is only self-definable. This may appear to be a circular definition. It is. Define a fitness function. When things change, what defines whether the change is for the better or the worse? This function will drive the evolution of the system. Choose it carefully. Define the environment. Draw a circle. Inside this circle, name all the possible users of the system, other systems which may interact with this system. This circle is the environment of the system. Think Scale (alternatively, Ignore Scale). What are the characteristics of your system which are independent of scale? Apply these intrinsics to your system as it grows. Think Adaptation. Is maintaining a system really different than porting it to a different site? Why invoke different technologies, or even design them to be different? Think of Emergent Properties. Although you may not know what may come from the system, at least you can be ready to acknowledge them when they appear. 97 Create Simple Initial Conditions. “Simplicate and add lightness” to the initial conditions of your system to all the evolutionary process to start. The important thing is to start the evolutionary process. Establish the Evolutionary Process. Even if payoff is intermittant or sparse, it is important to feedback the results of the fitness function to the system’s evolution. Consider Adaptation to be a Pervasive Process. Assume that nothing is forever, that all elements of your system must adapt, including the adaptation process. Point of View It is essential to realize that any hierarchical organization is decomposed from a Point of View (POV). The top left hand corner of an outline the or the top of a organization chart define the decompositional process for the transactions which occur in the organization. This POV may or may not reflect the best organization for a given function to be performed. Inverted Perspective Breaking out of an organization’s point of view can be a difficult process. There are too many pressures for maintaining the hierarchy for any but the boldest to venture out. Richard Feynman and Jonas Salk, however, made tremendous scientific inroads by using a technique of inverted perspective, which views the system from the perspective of one of the objects in it, rather that the “top down” decompositional view: Feynman’s essential insight was to place himself once again in the electron, to see what the electron would do at light speed. He would see the protons flashing toward himand they were therefore flattened relativistically into pancakes. Relativity also slowed their internal clocks, in effect, and from the electron’s point of view, froze the partons into immobility. His scheme reduced the messy interaction of an electron with a fog of different particles to a much simpler interaction of an electron with a single pointlike parton emerging from fog...The experimenters grasped it instantly.viii Jonas Salk wrote of a similar thought process: When I observed phenomena in the laboratory that I did not understand, I would also ask questions as if interrogating myself: “Why would I do if I were a virus or a cancer cell, or the immune system?” Before long, this internal dialogue became second nature to me; I found that my mind worked this way all the time.ix Inverted perspective can be used as a tool for breaking out of the decompositional process embedded in our computer systems as well. For example, the majority of health care computing resources over the past 25 years has been largely devoted to increasing the granularity and efficiency of the billing process. This is a very important process from the point of view of the hospital’s “bottom line”, and enabled them to charge for 98 things such as boxes of tissues which would not have been possible a generation ago. From the inverted perspective of the object in the system, i.e., the patient, however, this may not be the most critical breakdown of the information. Much like Feynman’s view of an electron interacting with a “messy fog” of particles, an inverted perspective of a human being in the health care system would be an individual working with a “messy fog” of information from hospitals, physicians, dentists, chiropractors, fitness centers, personal information, and other sources. This could have profound impact on the way we see things. For example, the “bottom line” of hospitals in the United States of hospitals is increased by several billions of dollars yearly by providing neonatal intensive care. Five hundred gram premature babies are saved, sometimes at a cost of a million dollars. From the perspective of the bottom line of the hospital, this is a very successful business. However, viewed from the inverted perspective of the mother or child, it would be far preferable to carry the baby to full term and have a normal birth. Many of the mothers delivering premature babies are poor and are not able to afford prenatal health care. Unfortunately, the benefits of providing prenatal health care do not show up on the bottom line of the organizations which benefit from providing neonatal intensive care. Transactional and Transformational Systems We could classify interaction in the context of a hierarchical structure as consisting of transactions. Systems built around transactions tend to be linear, for example, the bottom line of an accounting system is the linear sum of all transactions in the organization. They tend to be reduced to a single scalar quantity, (money being the most common), to simplify the linear “roll up” process. This quantity is measured in the currency of the hierarchy, from the point of view of the hierarchy. Transactions tend to be synchronized, with much hierarchical control of which transactions occur in what sequence. A banking system is a classical example of this type of system. Banking transactions are defined in terms of money, conform to the accounting system and procedures of the bank, and are carefully monitored to insure that they are executed in the proper sequence. ATM machines are a highly visible product of this model of operation. At the other end of the spectrum we have interaction which is based on web structures, consisting of transformations. There may be no hierarchical structure to the system at all, only browsing and explicit linking between objects which are collected in a “flat” pool. Interactions with the system cannot be characterized in a single scalar quantity, as is the case with transactional systems. The system is not linear nor synchronized, nor is it under the control of a single point of view. Observers have their own points of view their own inverted perspective. The system as a whole becomes a complex adaptive one, evolving over time as we have seen with the WWW.

Departments such as Laboratory, Pharmacy, Accounts Receivable, etc, each install independent systems. As the costs of duplication are realized, an “integrated approach” is called for. Sometimes, physicians ask for a system from their viewpoint (yet another point of view). But the fundamental problem—an infrastructure incapable of handling the conflicting information needs of its users, and the basic nonlinearity of the system—is ignored. vi Jon Postel, one of pioneers of the Internet, personal communication, August, 1993. vii Salk, Jonas, Anatomy of Reality, Columbia University Press, 1983 viii Gleick, James, Genius, The Life and Science of Richard Feynman,Vintage Books, New York, 1992, p 394 ix Salk, p. 7 iii 100
