  1. HL7 Government Projects Workgroup 2009-2011 Project Healthcare SOA Reference Architecture (H-SOA-RA) and EHR System Design Reference Model (EHR-SD RM)

  2. 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

  3. 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.

  4. Project Schedule • Year 1 Jan 09 – harmonize and catalogue priority IERs, DRs and candidate services • Mar 09 – map priority IERs, DRs and candidate services to EHR-S FM • Jun 09 - Mappings of V2.5, V3 products to EHR-S FM • Jun 09 – Healthcare SOA Reference Architecture (H-SOA-RA) version 2.0 • Jun 09 - HSSP Practical Guide for SOA in Health Care, Part II: Case Study • Jun 09 - Present at HL7 SOA Conference (for peer feedback) • H-SOA-RA V2.0 • HSSP case study • Sep 09 - EHR-SD RM Balloted “comments only” white paper, to socialize the project. • YEAR 2 Sep 10 - EHR-SD RM Balloted as informative document • YEAR 3 Sep 11 - EHR-SD RM Balloted as a standard

  5. Help Needed • Map V3 messages to the EHR-S FM • Establish relationship between CDA R1 and/or R2 to service oriented reference architecture • If you wish to participate, please contact: • Nancy.Orvis@tma.osd.mil or • Stephen.Hufnagel.ctr@tma.osd.mil
