The Definition of Interoperability in Healthcare
Goes something like this….
• “Interoperability is defined as the ability of two or more systems to exchange information and the ability of those systems to use the information that has been exchanged without special effort.”
• Source: ONC Report to Congress December 2015 https://www.healthit.gov/facas/sites/faca/files/HITPC_Final_ITF_Report_2015-12-16%20v3.pdf
10
This definition requires teasing out the meaning of the following…
• Systems
– Meaning health systems, e.g. hospitals, medical practices, imaging centers, home health providers, etc. AND
-- Information systems, e.g. EHRs, billings and claims/admin, lab and results reporting, etc.
• Use of the exchanged information “without special effort.” What about the exchange/transport itself?
• “Two or more” ? Is two a sufficient number?
11
New Definition of Interoperability
Let’s try it again…
• Interoperability is defined as the ability to exchange health information electronically across the boundaries of multiple organizational and health information systems, and to use the exchanged information, without special effort.
• Source: Kibbe, DC, February 2016
12
New Definition of Interoperability
With additional caveat: exchanges should be…
– Standards based
– Content neutral
– Secure
– Identity validated (authenticated)
13
Demand for Interoperability: Where did it start?
“We can't wait for interoperability. You all know this. It's past time. We have a series of really, really important standards baked into the 2014 Edition criteria. I think folks should assume the timelines will stick.”
Farzad Mostashari, MD
National Coordinator,
ONC, 10/10/2013
Demand for Interoperability has increasing number of sources
• Comes from several distinct but related sources – Meaningful Use $$, and specifically
MU Stage 2-3 objectives/metrics for Transitions of Care and Patient Engagement
– Expectations both business and clinical about the need to leverage huge national investment in EHRs
– Consumer demand to exercise HIPAA rights of access to PHI
– Value-based payment systems and
Merit-based Incentive Programs, MIPS. Population risk management.

Direct Exchange
• Additional examples of more focused, limited interoperable exchange platforms:
– ePrescribing
– Lab results reporting
– Billing and claims submission
– Others
• And there is considerable “cross over” among these efforts: – The Epic Community has created and shared over 190,000 unique Direct
addresses and exchange ~1.3M patient records via Direct each month, working with 10+ DirectTrust accredited HISPs.
– Epic Community members represent about 50% of the national eHealth Exchange participants, and as a group, are the most connected to the VA and SSA.
– Over 2/3s of HIEs report using Direct exchange both internally and to send alerts and reminders to provider organization members via their EHRs.
– eClinicalWorks providers are offered both non-accredited (internal to other eCW clients) Direct exchange and accredited Direct exchange options.
• Hypothesis: The growth in demand of facilitated, secure interoperable exchange during 2016-17 will depend upon:
– Positive network effects (create scale) • Size of the network for provider organizations facing MU and care
coordination, patient engagement, reporting mandates
• Usability of EHRs and PHRs with respect to exchange and use of data
• Readiness and maturity of new drivers and use cases of interoperable exchanges of health information
• Increasing requirements for security and trust in identity
– Negative network effects (cause congestion) • Content and payload frictions
• Health IT application interface (edge client) variability
• Provider and patient directory issues
• Costs of ID proofing and certificate management

EHR adoption has increased steadily since 2010 with almost all hospitals possessing a certified EHR (96.6%) 75% of hospitals have adopted at least a basic EHR, up from 59% in 2013. Small and rural hospitals continue to lag behind.
Adoption of Direct-enabled ONC-certified EHRs is now very high
www.DirectTrust.org 1101 Connecticut Ave NW, Washington, DC 20036 24
Hospitals report they are increasing Electronic exchange of summary of care records
Almost 10% of hospitals now report exchanging summary records with outside sources exclusively electronically. Two-thirds of hospitals report sending and receiving via both electronic and non-electronic format, e.g. mail, fax, e-fax, courier.

Adoption of Direct-enabled ONC-certified by Physicians 74%
Larger practices and primary care practice physicians adopt EHRs at a higher rate than smaller and solo practice physicians.

KLAS reported provider ratings of EHRs based on their ease of connection and interoperability. KLAS reports that information blocking is not widespread, but business models and lack of technical help remain problems.
Vendors are starting to be rated on their interoperability

American Hospital Association issues white paper on “why interoperability matters.”
In a landmark 2015 study, the AHA succinctly lists why EHR interoperability is essential for hospitals: • Care Coordination • Patient Engagement • Public health and quality measures
reporting. Value-based payment is key driver.
The report is highly critical of the current non-standardization of the CCDA, and calls for further federal government support of interoperability content standards and their use.

Direct Exchange
• Conclusions: The numbers of Direct-enabled EHRs serving hospitals and medical practices, who are in turn serviced by accredited Direct exchange service providers (HISPs, CA/RAs) is very, very large and is likely to expand further in 2016 as more provider organizations attest for Stage 2 MU in 2016 and 2017.
• HIEs, EHR-specific interoperability networks will also grow, especially EPIC CareEverywhere, but more slowly.
• eHealthExchange is unlikely to see significant growth.
• FHIR + open APIs 4-5 years away.
31
• Conclusion: Interoperability networks of all types face challenges from payload and content confusion, and from significant variability in EHR interface usability, e.g. for Direct exchange. These negative network effects have the potential to cause congestion and delay in network growth, and must be addressed if interoperable exchange is to become truly reliable and meet demand.

Brief Case Studies of the Use Cases for Direct Exchange: Baylor Scott and White, the VA, Tenet Health System
37
Key Use Cases for VA Direct Messaging
Use Case
1 Care in the Community Referral and other health information shared with community health care providers
2 Transitions of Care (ToC) Documents
VA receives (or sends) CCDA(s) from community health care provider for a Veteran. Supports partners Meaningful Use 2 (MU2) attestation
3 My HealtheVet (Patient Portal) Blue Button Direct
My HealtheVet users can send their CCDA to a Direct address of their choosing through Direct
4 Admission/Discharge/Transfer (ADT) Non-VA partner (often an HIE) sends ADT information to a VA Medical Center for a Veteran who receives care in the community
5 Long-Term Care (LTC) Sharing administrative and clinical information for a Veteran in a LTC facility (including State Veterans Homes)
6 Others? VA is open to using Direct for other use cases that support Veteran health care

VA Use Case: Care in the Community
• VA pays for millions of “fee consults” for Veterans each year
• Each one requires administrative and clinical documentation including: 1) authorization for Veteran to receive care paid for by VA
2) results of the consult
• Use of Direct Messaging is more secure and efficient than faxing, mailing, or hand carrying

Success Clearing Backlog of Consult Results
• The Ochsner Health System in New Orleans had over 1,000 consultation reports to provide to VA
• Using Direct Messaging, the documents Ochsner sent the reports securely to the New Orleans VA Medical Center as a pdf attached to a Direct message
41
• This saved VA end users many hours of dealing with faxes and scanning them so the information could be included in the Veterans’ electronic health record

HIMSS Survey shows Direct exchange now mainstream
Current market view of the usage, value and future of Direct Messaging
Themes from the survey results:
• substantial use of Direct in support of care coordination use cases,
• broad availability to a provider directory but great variability in the method of access,
• continued challenges incorporating structured data into the EHR,
• extensive membership [of provider organizations] in a HISP,
• some knowledge of the availability of Direct messaging among the clinician community, and
• that most participating organizations support Direct as the method choice for exchanging data.

Short lexicon of terms
Health Information Service Provider, HISP An entity or service providing its subscribers Direct accounts, addresses and secure, encrypted exchange of messages between users within the same domain, and also with users in different domains, that is, who are subscribers of different HISPs. It is typically also the responsibility for a HISP to arrange for its subscribers’ identity proofing and verification (the Registration Authority function) and for its subscribers’ digital certificate issuance and management (the Certificate Authority function). HISPs may be organized along several different business models. For example, an EHR technology vendor may operate a HISP internally for its customers. A so-called “full service” HISP may operate a stand alone business, and partner with several EHRs as well as offer its Direct services through a web portal or other set of tools and devices.
Short lexicon of terms Direct Project A public-private sector initiative sponsored and run by ONC whose aim was to create a simple, secure, and open standard for transport of messages and attachments between health care participants over the Internet, regardless of end-user technology. Direct Standard The outcome of the Direct Project. A set of protocols and specifications, along with a security and trust architecture, for simple, secure, inter-vendor communications over the Internet for use by health care professionals and patients. Direct Message Exchange Use or deployment by individuals or entities of health information exchange utilizing the Direct standard. Also sometimes referred to as Directed “push” exchange, Direct exchange. Direct User or Subscriber An organization or an individual that participates in sending and receiving messages and attachments using technology equipped to do so, e.g an EHR or a web portal, via the Direct standard, and who has the authority to do so.
