Section 1.5 Assess
HIE Technology Readiness Inventory
Understand health information exchange (HIE) definitions and technology. Assess your facility’s
readiness to utilize the HIE Service Provider (HIESP) that meets your needs.
Time needed: 2 hours to read this document, up to 8 hours to complete the linked readiness
checklist.
Suggested other tools: 1.3 Interoperability for EHR and HIE
Assumed Knowledge: EHR Basics
How to Use
1. Review basic definitions and standards associated with HIE.
2. Review the forms HIE can take, and the technology used in each.
3. Follow the link to the HIMSS readiness checklist to identify all types of health information
exchange in which your facility is interested. Use this checklist when evaluating HIE options
within your area.
Basic Definitions
Standard: “A standard…provides requirements, specifications, guidelines or characteristics that can
be used consistently to ensure that materials, products, processes and services are fit for their
purpose” (iso.org, 2014).
Standards are important because without them, different EHR systems are unable to communicate
with one another, therefore making “exchange” of information between different providers and
caregivers impossible. In a perfect world, standards precede exchange. Historically, in the real
world, there has been slow development of standards, and slow movement to adopt shared standards.
Different vendors and organizations have programmed their systems to different (or non-established)
standards. The passage of the HiTech Act and Meaningful Use criteria requires vendors and
organizations to use standards in their EHRs and for HIE. This is notable, although many types of
health care providers covered by the MN 2015 Mandate for Interoperable Electronic Records 1 are
not covered by the Meaningful Use mandates; since hospitals and medical clinics are covered,
vendors are building standards into their EHR products, to the benefit of all sorts of healthcare
organizations.
Health Information Exchange (HIE): In its Practical Guide to Understanding HIE2 , the Minnesota
Department of Health defines HIE as: “HIE refers to the secure electronic sending and receiving of
clinical health information in ways that the information can be understood by both the sender and the
receiver of the information.”
The federal government provides this definition on HealthIT.gov “Electronic health information
exchange (HIE) allows doctors, nurses, pharmacists, other health care providers and patients to

appropriately access and securely share a patient’s vital medical information electronically—
improving the speed, quality, safety and cost of patient care” (HealthIT.gov, 2014).
Definitions Specific to HIE
There are three types of standards associated with HIE:
1. Transaction standards
2. Semantic standards
3. Process standards
Transaction standards define which data fields are transmitted and how they are organized for
transmission. There are many transaction standards that are specific to the healthcare domain. These
transaction standards can be further divided into message formats (how the message is “put
together”, message transport (how the message is transmitted), and message security (keeping the
data private and secure during transmission).
Semantic standards are probably the most recognizable of standards to clinicians. Semantic
standards define the range and meaning of variables (pieces of data) being transmitted. Some
examples commonly found in health care are:
Standard
ICD
CPT
Meaning
International Classification of Diseases
Current Procedural Terminology
Details
Published by the World Health Organization
Describes medical, surgical and diagnostic services.
Maintained by the
American Medical Association
HCPCS
Healthcare Common Procedure Coding
System
Based on CPT and designed to provide a standardized
coding system for describing the specific items and
services provided in the delivery of healthcare. Used
for reporting to Medicare, Medicaid and other payers.
LOINC
Logical Observation Identifiers Names

Process standards refer to how work processes are completed in a setting. This is where the term
“workflow” comes in. For example, the workflow for admitting a patient exists in some care settings
(inpatient, rehabilitation facility, long term care facility, home health), but not in others (ambulatory
clinic). Different workflows in different care settings require the content of messages to be
constructed in different ways so that the right data land in the right spot from transmission to receipt.
Forms of HIE and Associated Technology:
1. Direct is a simple, scalable, secure, and standards-based way for participants to send
authenticated, encrypted health information directly to known, trusted recipients over the
Internet. Direct is used by providers to easily and securely send health information—such as
lab orders and results, referrals, prescriptions, or discharge summaries—directly to another
provider, and increasingly to patients. Direct is also being used for sending immunization
data to public health organizations and to report quality measures to the Centers for Medicare
Section 1 Assess—HIE Technology Readiness Inventory - 2
& Medicaid Services (CMS). Although many providers use a dedicated virtual private
network (VPN) to transmit claims to health plans (or billing information to billing services
and/or health care clearinghouses), Direct could also be used for this purpose. Directed
sometimes is referred to as Push, where information is exchanged between two entities with
an established relationship for routine workflow and processes.This exchange can be
conducted over the Internet (rather than through a VPN) using the Direct protocol—a
federally approved, secure means to exchange email. (See Section 4.10 Using Direct for
HIE).
2. Query-based exchange is used by providers to search and discover accessible information
about a client. This type of exchange, also referred to as Pull, is often used when there is an
unplanned episode of care, such as by an emergency department or behavioral health
specialists seeking information on what medications a patient is taking, or by a hospital
presented with a woman in labor and needing pre-natal care information from an obstetrician
or local public health clinic. Such an exchange requires the use of an established health
information exchange service provider (HIESP) and a form of secure communication called
CONNECT. This form of exchange supports a variety of technical services (described below)
including client consent management and the ability to provide Pull and Push services in a
subscription mode. For example, a provider may arrange for a continual update to a client’s
medications. (See Section 4.11 Using CONNECT for HIE.)
3. Consumer-mediated exchange provides clients with access to their health information,
allowing them to manage their health care online in a similar fashion to how they might
manage their finances through online banking. The federal government is a strong supporter
of such exchange. The healthIT.gov website describes that “When in control of their own
health information, patients can actively participate in their care coordination by providing
other providers with their health information, identifying and correcting wrong or missing
health information, identifying and correcting billing information, tracking and monitoring
their own health” (see: http://www.healthit.gov/providers-professionals/health-informationexchange/what-hie).
Consumer-mediated exchange may be accomplished through a personal health record that is tethered
to a provider or health plan, or is a commercial product. The federal government (Medicare,
Department of Defense, and Veterans Administration) and other health plans are adopting Blue
Button® technology. Originally, Blue Button supported only the downloading of human-readable
data in ASCII format. Since January 2013, the Office of the National Coordinator for Health
Information Technology (ONC) announced Blue Button+, which enables both human-readable and
machine-readable formats for the data being exchanged.
The Minnesota HIE Landscape:
In Minnesota, there are two types of HIE Service Providers who have been granted a Certificate of
Authority to operate:

Health Information Organization (HIO): An entity that provides all electronic capabilities for
the transmission of clinical transactions necessary for “meaningful use” of electronic health
records, in accordance with nationally recognized standards
(http://www.health.state.mn.us/divs/hpsc/ohit/certified.html).

Health Data Intermediary (HDI): An entity that provides the infrastructure to connect
computer systems or other electronic devices used by health care providers, laboratories,
pharmacies, health plans, third-party administrators, or pharmacy benefit managers to
facilitate the secure transmission of health information, including pharmaceutical electronic
data intermediaries as defined in Minn. Stat. §62J.495, and Health Internet Service Providers
Section 1 Assess—HIE Technology Readiness Inventory - 3
(HISP) as defined by the Nationwide Health Information Network (NwHIN) Direct Project.
Please note, to the extent that information is shared without the use of an intermediary it is
outside the scope of Minnesota's oversight law
(http://www.health.state.mn.us/divs/hpsc/ohit/certified.html).

Readiness Checklist
HIMSS has put together a “checklist” that organizations can use to step through various clinical
scenarios to identify detailed technology needs in order to prepare for HIE. This checklist is long
and comprehensive. Not all steps will be appropriate for your organization. Nonetheless, read all the
entries and work through those that apply to the types of exchange you want to pursue.
