Project Intent

• Implement a step in HL7 roadmap– Identify gaps and overlaps in HL7’s portfolio– Identify gaps in the EHR-S FM – Pilot HL7 ARB Services Aware Enterprise Architecture Framework (SAEAF)

methodology• Validate HITSP Multi-Enterprise Architecture of Networked Services Standards

(MEANS) methodology• Create Healthcare SOA Reference Architecture (H-SOA-RA) Version 2• Create Healthcare SOA EHR System Design Reference Model (EHR-SD RM)

based on EHR-S FM• Create prototype architectural case study using HL7 HSSP Practical Guide for

SOA in Healthcare “sample health” and service specifications, EHR-S FM, EHR-SD RM, AHIC Use Cases, HITSP Interoperability Specifications and NHIN services.

• Demonstrate standards-driven Model Driven Architecture (MDA) approach

Project Scope

This project will mature the April 2008 Healthcare Services Oriented Reference Architecture (H-SOA-RA) version 1.0 into H-SOA-RA Version 2.0 and then integrate it into an EHR System Design Reference Model (EHR-SD RM), using the HL7 SOA-Aware Enterprise Architecture Framework (SAEAF), HITSP Multi-Enterprise Architecture of Networked Services Standards (MEANS), EHR System Functional Model (EHR-S FM). Emphasis will be placed on maintaining AHIC, HITSP, NHIN and CCHIT conformance by maintaining Information Exchange Requirements (IERs) and Data Requirements (DRs) traceability. Mapping and analysis of the HL7 product portfolio against the EHR-S FM will be used to integrate the reference architecture with HL7 product lines and initially mature the resulting model as a technical white papers, then an informative reference model and finally a standard reference model. An HSSP based prototype case study architectural specification will be built to validate the effort.
