Center for Health Information and Decision Systems Volume 1, Issue 2A RESEARCH BRIEFING EARLY FINDINGS ON PERSONAL HEALTH RECORDS AND INDIVIDUAL USE Ritu Agarwal, Professor and Robert H. Smith Dean’s Chair of Information Systems and Director of CHIDS Corey M. Angst, Research Assistant Professor and Associate Director of CHIDS The transformational power of information technology in altering the nature of competition in an industry and creating value for both firms and consumers has long been acknowledged in diverse industry sectors such as airlines, financial services, and retailing. A common characteristic among industries that have experienced such transformations is that they are information intensive – i.e., a significant proportion of their valuecreation activities occurs through the storage, processing, and analysis of data. The transformation has typically been attributed to specific software applications – e.g., the Sabre System in the airline industry and Merrill Lynch’s Cash Management System in the brokerage industry – that provide the trigger for far-reaching changes. Healthcare cost account for nearly 10% of GDP in most industrialized nations and over 15% in the US. Healthcare also represents a sector with significant consequential outcomes – the quality of care delivered often spells the difference between life and death. Thus, it is not surprising that considerable emphasis by governments, policy makers, and other stakeholders in this sector is being given to trying to better understand how the delivery of care can be improved. Human capital in the form of knowledge and skills is doubtless a critical input factor for the quality of healthcare; however, to the extent that healthcare is an information intensive, knowledge-based activity that requires high reliability in operations, another important input is technology that can aid in the “movement” of critical information. In this briefing we explore an emergent IT application – the electronic personal health record (PHR) that arguably, offers the same potential for revolutionary, discontinuous change in the healthcare sector. In very general terms, a PHR is an electronic, universally available, lifelong resource of health information that an individual uses to make health decisions. It can be Winter 2006 made available through the use of a web-based, ASP (application service provider) model, a stand-alone PCbased platform, or a portable storage device such as a USB-flash drive. The information in the PHR is owned and managed by the patient. PHR features typically include self-tracking and monitoring of health information and self-entry or downloading of information related to diagnoses, medications, laboratory tests, and immunizations. The PHR sometimes has the ability to receive and store information from a doctor's electronic medical record (EMR) or other electronic data source. Some PHRs include features that notify the user of drugto-drug interactions and dosage warnings. We conducted an exploratory empirical study to understand the characteristics of individuals who are early adopters of PHR software. We also sought to understand what type of value individuals perceive in the PHR, and the drivers of their usage intentions. We found three distinct perceived components of value: (1) compliance, (2) connectedness, and (3) convenience. We also found that different demographic and medical condition variables influence the type of value a user sees in a PHR. Finally, our results show that future intentions to use a PHR are driven by perceptions that the PHR provides compliance and improves a patient’s relationship and connectedness with their healthcare provider. Defining the PHR Figure 1 shows a screen shot of a typical PHR. Figure 1.

CHIDS Research Briefings are published on a quarterly basis to update CHIDS members. CHIDS Research Briefing, vol.1, issue 2A A PHR is fundamentally a tool for end-users. It is helpful to draw a connection between a PHR and a personal financial management software package such as ® Quicken . With Quicken, an individual can track her finances by monitoring personal checks, logging ATM transactions, and tracking deposits, to name but a few features. Then, at the end of the month, the individual can compare the previous-month’s transactions with those on file at the defined bank. This process could be labeled as dissociative, since both ‘systems’ operate in isolation. On the other hand, Quicken offers a feature that allows the user to continue to maintain her private banking information on her personal computer, but also gives the option of downloading data directly from the participating bank as a means of reconciling the account. The functionality offered by a typical PHR is summarized in Table 1 below. Information • General personal information • Family medical history • Emergency contacts • Personal medical contacts • Insurance coverage(s) • Reminders Visits and Hospitalizations • Conditions • Tests • Treatments • Medicines • Immunizations • Miscellaneous data Medical Details • Active conditions • Vitals and profiles (incl. graphing) • Test results • Treatments received • Drugs administered • Immunizations • Miscellaneous data Communications • Records of letters, calls, faxes, emails • Printable emergency card • All screens generate into reports • All reports can be printed or emailed Medical Summary • Conditions, problems • Tests • Immunizations • Medications • Treatments and therapies • Other orders, recommendations Optional: Sponsor customization • Introductory branded screens and reports • Custom pick-lists of PHR information • Dedicated web links • Dedicated field-level links • Customized profiles, guidelines • Custom “Community of Care” page that auto-builds to user’s needs based on sponsorselected information Page 2 Winter 2006 record systems. In most cases, information is only made available for download to the patient’s personal record, but in some systems, such as one run by Brigham and Women’s Hospital in Boston, MA, patients are also given the ability to upload notes and data into their permanent medical record, schedule appointments, and email doctors, to name a few features. Early Adopters of PHRs Our goal was to study what types of perceptions individuals have about the use of PHRs, and what the determinants of their intentions to use the PHR are. Following prior theory, the conceptual model underlying the study, shown in Figure 2, suggests that individual characteristics of two varieties: demographics, and those related specifically to the individual’s medical condition, predict the value cognitions individuals possess in regard to using the software. These cognitions, in turn, drive their usage intentions. Additionally, we allow for the possibility that individual characteristics exhibit direct effects on usage intentions, over and above their mediated influence via perceived value. The demographic variables included in the study were age, education, and income. The medical conditionrelated variables were, the existence of a chronic health condition in the individual’s circle of care, whether or not multiple medications are required for this chronic condition, and the total number of doctor visits. Demographics o Age o Income o Education Perceived Value of Using a PHR (PV) Behavioral Intention to Use a PHR (BI) Medical Condition o Chronic Illness (ILLNESS) o Multiple Medications (MED) o Number of doctor visits (DOC) Table 1. Typical PHR Functionality A PHR is similar in this respect. A user can maintain all health information on her personal computer, entering data from doctor visits as they occur and tracking medications and dosages. In this case, two separate databases (in actuality, several databases are maintained, as it is very common for people to see multiple health providers and it is typical that each maintains its own isolated medical database record) are managed independently. There is, however, technology available such that a user/patient can have a direct link through the Internet or a portable device such as a USBflash drive to participating providers’ electronic health Figure 2. Conceptual Model Study Context and Sample We mailed a survey to 813 purchasers of an electronic personal health record. These 813 users represent people that had purchased the software through the company’s website, ordered it over the telephone, or through a 3rd party distributor in the 3-month period just prior to our study. There were 47 unusable or undeliverable surveys and 190 complete surveys, representing a 24.8% response rate. In addition to questions measuring the research variables in Figure 2, CHIDS ▫ Van Munching Hall ▫ College Park, MD ▫ University of Maryland ▫ www.smith.umd.edu/chids ▫ chids@rhsmith.umd.edu ▫ ph. 301.405.0702 CHIDS Research Briefing, vol.1, issue 2A Page 3 we also asked users what their most important healthcare tasks were, and what the primary uses for a PHR might be. A description of the sample is provided in Table 2. Description Value Surveys sent 813 Unusable or undeliverable 47 Usable surveys 190 Response Rate 24.8% Male/Female 72/28 % of users with chronic illness 63% Average number visits to doctor/yr 7.1 Average years of computer experience Table 2: Sample Description 15.3 In prior work we found that individuals’ beliefs with regard to the value of PHRs consisted of three distinct dimensions: “compliance (PVa),” “connectedness with one’s healthcare provider (PVb),” and “convenience (PVc).” Value: Compliance (PVa) • Using the PHR helps me to perform my healthcare activities (by reminding me to make and keep my appointments, etc.) • Using the PHR helps me to stay on schedule with my healthcare activities (such as getting my regular checkup) • Using the PHR helps me perform my healthcare activities at the appropriate times (such as refilling prescriptions) • Using the PHR helps me remember to perform my health care activities (like testing my blood sugar) • Using the PHR allows me to accomplish more of my healthcare objectives (such as losing weight) Value: Connectedness (PVb) • Using the PHR improves communications between my care providers and me • Using the PHR improves my relationship with my care providers • Reducing the number of forms to fill-out during registration by having the information available on my PHR is valuable to me Value: Convenience (PVc) • It would be valuable to have my health information available at all times • It would be valuable to have my complete medical record with me at all times • It is critical to have my emergency medical information with me at all times Winter 2006 • It would be valuable to have all of my healthcare information located in one place In the data we collected, we found that the typical PHR user is male, between the ages of 51 to 60, has a chronic illness, takes multiple medications daily, and goes to the doctor more than 7 times annually. This user is also well educated and falls into the upper-middle socio-economic class. Most Important Health Care Tasks Track / Trend Lab Results 4.1% Other 20.7% Ability to organize data in useful way 18.6% Track Vitals / Self-Monitor 5.2% Store Tests, Evaluations. 6.1% Access to doctor reports and lab 4.1% Manage Info/Knowledge 8.8% Medication Tracking 10.9% Medical History Archive 21.6% In terms of healthcare tasks, the most frequently mentioned was maintaining a medical history archive, followed by the ability to organize data in useful ways. Thus, it appears that users view the PHR as an electronic repository of critical medical information. Primary Uses for PHR Other 5.9% Family Medical History 26.4% Track Lab Results 14.1% Track Medications 18.7% Track/Trend my health 13.5% Track Doctor Visits 21.4% This is echoed in the primary uses cited for the PHR, where the maintenance of family medical history and keeping track of doctor visits were the most popular uses of the PHR. Data Analysis, Results, and Discussion We used structural equation modeling techniques with the EQS computer program to perform all confirmatory factor and structural analyses. We first tested the relationship between the demographic and medical condition variables and behavioral intention. The age of the subject and the education level were found to be significant predictors of intention to use. These results showed that younger and less educated users have greater intentions for future use. Our next step was to test a mediated model with the perceived value constructs acting as mediators. When we introduced the mediators, both age and education became non- CHIDS ▫ Van Munching Hall ▫ College Park, MD ▫ University of Maryland ▫ www.smith.umd.edu/chids ▫ chids@rhsmith.umd.edu ▫ ph. 301.405.0702 CHIDS Research Briefing, vol.1, issue 2A significant and PVa and PVb emerged as significant predictors of BI, collectively explaining over 40% of the variance in usage intentions. Our findings show that the effects of individual characteristics on usage intentions for PHR software are fully mediated by value perceptions. Interestingly, the results suggest that value is perceived very differently across the demographic and medical condition variables. Education is the only variable significantly related to the desire for compliance (PVa), and this relationship is negative. Thus, less educated users believe that the software will assist them in becoming more organized in managing their medical information. The presence of a chronic medical condition is associated with a perception that the PHR can yield a closer relationship and greater connectedness with healthcare providers (PVb), while age and income are negatively related to such value. Not surprisingly, younger individuals have a lower desire for close relationships because their health is more likely to be in good condition. High income users possibly have other mechanisms for ensuring high-quality healthcare (e.g., using private physicians). Finally, the convenience aspects of using a PHR (PVc) are negatively associated with age, and positively associated with the severity of the health condition as assessed by the need for multiple medications on a daily basis and more frequent doctor visits. Overall, the medical condition variables predict PVb and PVc, but not PVa. We also find that convenience (PVc) is not a significant predictor of usage intentions. In summary, the pattern of results reveals that individual profiles in regard to demographic and medical condition factors yield varying levels and types of value perceptions. The lack of a relationship between the medical condition variables and perceived value in the form of compliance suggests that such value is likely to be salient for most users, independent of whether they have a need to manage their health proactively. As might be expected, value perceptions related to closer interaction with a healthcare professional and empowerment are amplified in the presence of severe medical conditions. Economically disadvantaged users that may otherwise be challenged in regard to receiving medical attention, view the PHR as an important means for staying more connected with their doctors. To the degree that behavioral intentions drive actual adoption and use, overall the findings indicate that the early adopters of PHRs are likely to be individuals who are less educated, older, less wealthy, and suffering from a chronic illness. Conclusion The motivation for this study is the pressing need to contain rising healthcare costs while simultaneously ensuring that medical errors are reduced and patient Page 4 Winter 2006 safety is enhanced. Technologies such as the PHR can assist in these endeavors by both providing a repository of critical data for use by clinicians, and aiding patients in becoming more proactive in the management of their health. Ongoing research that can aid in developing adoption strategies is critical.
