Sept 13-15, 2004IHE Interoperability Workshop 4 IHE 2004 achievements and expanding scope Over 80 vendors involved world-wide, 4 Technical Frameworks 31 Integration Profiles, Testing at yearly Connectathons, Demonstrations at major exhibitions world-wide Provider-Vendor cooperation to accelerate standards adoption

Sept 13-15, 2004IHE Interoperability Workshop 5 IHE Process Users and vendors work together to identify and design solutions for integration problems Intensive process with annual cycles:  Identify key healthcare workflows and integration problems  Research & select standards to specify a solution  Write, review and publish IHE Technical Framework  Perform cross-testing at “Connectathon”  Demonstrations at tradeshows (HIMSS/RSNA…)

Sept 13-15, 2004IHE Interoperability Workshop 10 Patient Identifier Cross-referencing Abstract / Scope Allow all enterprise participants to register the identifiers they use for patients in their domain Support any systems (small and large) to query for other patients IDS in other patient identification domains Optionally, notify those systems when systems from other patient identification domains update identifiers for their patients

Sept 13-15, 2004IHE Interoperability Workshop 11 Patient Identifier Cross-referencing Value Proposition Provide to any systems a standard interface to map its patient IDs onto patient IDs of other Patient Identification domains. Maintain all systems’ identifiers for a patient in a single location Use any algorithms (encapsulated) to find matching patients across disparate identifier domains Lower cost for synchronizing data across systems  No need to force identifier and format changes onto existing systems

Sept 13-15, 2004IHE Interoperability Workshop 15 Patient Identifier Cross-referencing Key Benefits No need for a Master Patient Identifier (facilitates legal constraints). PIX Manager does not need to produce “consolidated demographics”. Any Patient Id Domain may be considered as providing “master patient ids” (see next slides). Patient Demographics is and remains a responsibility of ADTs Actors. In addition to Patient Registration distribution (e.g. Rad & Lab SWF), a Patient Demographics Query Int. Profile is planned
