2. Page 2 Background This presentation represents the collective input and thinking from the collective participants involved in the Healthcare Services Specification Project. Represented were members from –Object Management Group (OMG) –Health Level Seven (HL7) –Integrating the Healthcare Enterprise (IHE) This presentation is intended to describe the purpose, role, and importance of industry-standard service interface specifications

3. Page 3 Why “common services” and not just “messages”?* A common practice in healthcare, just not yet in healthcare IT Many key products use them but do not expose interfaces Ensures functional consistency across applications Accepted industry best practice Furthers authoritative sources of data Minimizes duplication across applications, reuse Messages can be either payloads in or infrastructure beneath services Service-oriented architecture is just automation of common services *slide adapted from a Veterans Health Administration Presentation, used with permission

4. Page 4 What is the Healthcare Service Specification Project? An effort to create common “service interface specifications” tractable within Health IT A joint standards development project involving Health Level 7 (HL7) and the Object Management Group (OMG) Its objectives are: –To create useful, usable healthcare standards that address functions, semantics and technologies –To complement existing work and leverage existing standards –To focus on practical needs and not perfection –To capitalize on industry talent through open community participation

5. Page 5 Where would these specifications be used Inter-Enterprise (such as NHIN, RHIOs, LHINs) –By functionally specifying behavior, roles between applications and products are clarified, and the technologies supporting them can be profiled and sharpened Intra-Enterprise –Standardization on functionality allows for better integration of off-the-shelf and custom development environments, and promotes more of a “plug and play” environment Intra-Product –Facilitates vendors ability to integrate third-party value-add components and speed design phase with higher confidence Custom-Implementation –Affords organizations wishing to custom-develop the opportunity to later integrate off-the-shelf

6. Page 6 The Approach HL7 to lead in service selection, functional elaboration, and conformance criteria OMG to lead in technical specification Both organizations jointly participate in all activities Work products will be “owned” by only one organization but used collaboratively “Operate as one project” as a principle Actively seek vendor participation Engage IHE community

7. Page 7 The Value of Collaboration HL7 brings… –Healthcare semantic interoperability expertise –Rich, extensive international community perspective –Diverse membership base OMG brings –distributed systems architecture and modeling excellence –Effective, efficient, rapid process –Premise that standards must be implemented Resulting in… –Services will be identified by the community needing them –Improved methodology resultant from functional and architectural merging of the two groups –Facilitation of multi-platform implementation and broader implementation community

10. Page 10 For Product Consumers and Users… The Impacts and Rationale of HSSP Specifications ImpactsRationale Promotes deployment ease and flexibility Specifications will support multiple topologies Consistency at the interface level assures asset protection Standard interfaces means that conformant components are substitutable Multiple vendor product use/ interoperability Using compliant products means side-by-side interoperation of multiple product offerings Increased buyer/product offeringsConsumer demand will create increased marketplace competition Facilitates integrationUnity in purpose and consistency in interface eases integration burden Time to marketAvailability of an industry-accepted component interface eases product development burden Requirements definition – influence vendors in a direct way Participation by provider and payer community is direct expression of business need Lower cost = wider deployment = higher quality service

11. Page 11 Product Vendor … The Impacts and Rationale of HSSP Specifications ImpactsRationale Market opportunity – ability to grow business / “Grow the pie” Standardization of interfaces eases cost-of-entry to markets Conformance adds legitimacy to product offering Consumers view conformance as a confidence metric Reduced time and cost to market Use of 3 rd party components Simplify / reuse of design Ability to reuse design ideas, incorporate off-the- shelf components into value-add offerings Participation provides the ability to influence the standard You can shape the standard to be supportive of your product architecture

12. Page 12 Regulatory/Policy/Legislative … The Impacts and Rationale of HSSP Specifications ImpactsRationale Establishing objective assessment criteria: Measurement criteria for regulatory compliance Inclusion of rigorous conformance assertions benefits compliance and verification Allows for technology change within the regulation Concurrent support of multiple technologies allows for technology evolution Offering an easy/easier solution that is complete and actionable / ease the path to adoption: How do we “Pick the winning horse”? “Opportunity cost” of using the wrong standard has big implications HSSP integrates function/ behavior, data, and protocol promoting an integrated solution set Solution that complements existing standards HSSP is using HL7 semantics, OMG processes, IHE testing, and established technology protocols

13. Page 13 Research … The Impacts and Rationale of HSSP Specifications ImpactsRationale Promotes accessibility to “raw” information Strong emphasis on semantically rigorous data and query/retrieval Enabler for collaborative studies, e.g. de-identification, retrieval, etc. Leveraged use of identity service enables de- identification Enlarges cell and sample sizes based on interoperability Facilitates responsiveness to bio- surveillance requirements Standard interfaces accommodate dynamic and emerging strategies and tools Enables construction of higher-order service stacks with less investment Composable nature of services promotes construction

14. Page 14 Implementer/Integrator … The Impacts and Rationale of HSSP Specifications ImpactsRationale Reduced integration time and cost resulting from the use of standard tooling Use of standard in off-the-shelf tools facilitates their use Risk mitigation (skill portability/ training advantage, vendor independence, substitutability) By training staff in the standard, skills are portable across tools Creates a value offering opportunity based on the ability to deliver using these service standards Allows staff and solutions to build upon the use of the standard and not technologies Improved ability to deliver and support interfaces that have been implemented Using services speeds project design phases and promotes reuse

15. Page 15 SDOs … The Impacts and Rationale of HSSP Specifications ImpactsRationale Useable standardsEmphasis on practicality Market-focused standards based on commercial implementations Shortens time required to develop specifications and encourages collaboration Promotes harmonization, cooperation, cohesion among standards communities Integration of function, data, and technology promotes leveraged reuse More members/involvement = more revenue & better specs Practical, market-focus and iterative timeline promotes participation and results

17. Page 17 What Participants are Saying… “Kaiser Permanente I.T. is currently transitioning to an SOA-based approach to business and systems integration. Availability of industry standard services will bring many benefits towards this goal in terms of speed of implementation, flexibility and reduced cost. I am very pleased that both HL7 and OMG are committed to this timely effort.”, Alan Honey, Enterprise Architect (Principal), Kaiser-Permanente “The creation of a health Informatics infrastructure based upon a service-based architecture grounded in comparable data has the potential to improve healthcare delivery and greatly enhance patient safety.”, Peter L. Elkin, MD, FACP, Professor of Medicine, Mayo Clinic College of Medicine “The MedicAlert mission – to protect and save lives – requires a repository of comprehensive medical information that comes from multiple sources for our members. Our SOA-based infrastructure demands the rich and flexible capabilities that are provided by these standard interoperable services.”, David Harrington, CTO, MedicAlert Foundation “The Eclipse Foundation is pleased to support an open source project dedicated to building frameworks, components, and exemplary tools to make it easy and cost-effective to build and deploy healthcare software solutions. This Eclipse Open Healthcare Framework project will leverage the Eclipse Platform developed by IBM, Intel, Wind River, Actuate, Borland, BEA, Computer Associates and others.” Mike Milinkovich, Executive Director, Eclipse Foundation “The time is now and the place is here in this joint OMG/HL7 project. Never before has the industry been closer to cogent, clear healthcare IT data model and service standards that can provide true interoperability in a short timeframe, with open- source implementations making availability abundant.”, Richard Mark Soley, Ph.D., Chairman and CEO, OMG
