BackgroundBackground
• 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

Why “common services” and not just “messages”?*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

What is the Healthcare Service Specification Project? 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

Where would these specifications be usedWhere 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

The ApproachThe 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
Page 7
The Value of Collaboration 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

For Product Consumers and Users…The Impacts and Rationale of HSSP SpecificationsFor Product Consumers and Users…The Impacts and Rationale of HSSP Specifications
Impacts Rationale
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 offerings Consumer demand will create increased marketplace competition
Facilitates integration Unity in purpose and consistency in interface eases integration burden
Time to market Availability 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
Page 11
Product Vendor …The Impacts and Rationale of HSSP SpecificationsProduct Vendor …The Impacts and Rationale of HSSP Specifications
Impacts Rationale
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 3rd 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
Page 12
Regulatory/Policy/Legislative …The Impacts and Rationale of HSSP SpecificationsRegulatory/Policy/Legislative …The Impacts and Rationale of HSSP Specifications
Impacts Rationale
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
Page 13
Research …The Impacts and Rationale of HSSP SpecificationsResearch …The Impacts and Rationale of HSSP Specifications
Impacts Rationale
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
Page 14
Implementer/Integrator …The Impacts and Rationale of HSSP SpecificationsImplementer/Integrator …The Impacts and Rationale of HSSP Specifications
Impacts Rationale
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
Page 15
SDOs …The Impacts and Rationale of HSSP SpecificationsSDOs …The Impacts and Rationale of HSSP Specifications
Impacts Rationale
Useable standards Emphasis 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
