Healthcare Services Specification Project The Business Case and Importance of Services HL7 Services Specification Project Workgroup OMG Healthcare Domain Task Force 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 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? 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 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 e
