IT Infrastructure Profiles 2004 Patient Identifier Cross-referencing for MPI (PIX) Retrieve Information for Display (RID) Consistent Time (CT) Patient Synchronized Applications (PSA) Enterprise User Authentication (EUA) 2005 Patient Demographic Query (PDQ) Cross Enterprise Document Sharing (XDS) Audit Trail and Note Authentication (ATNA) Personnel White Pages (PWP) 2006 Cross-Enterprise User Authentication (XUA) Document Digital Signature (DSG) – Notification of Document Availability (NAV) Patient Administration/Management (PAM) • Patient Identifier Cross-referencing for MPI (PIX) • (Map patient identifiers across independent identification domains) Interoperability Strategy Workshop

4. Patient Identifier Cross-referencing for MPIAbstract / Scope • Allow all enterprise participants to register the identifiers they use for patients in their domain • Participants retain control over their own domain’s patient index(es) • Support domain systems’ queries for other systems’ identifiers for their patients • Optionally, notify domain systems when other systems update identifiers for their patients Interoperability Strategy Workshop

5. Patient Identifier Cross-referencing for MPIValue Proposition • 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 • Leverages standards and transactions already used within IHE Interoperability Strategy Workshop

9. Patient Identifier Cross-referencing for MPIActors Patient Identity Source • Definition • Assigns patient identities within its own domain • Notifies Patient Identifier Cross-reference Manager of all events related to patient identification (creation, merge, etc.) • Example: Registration (ADT) Actor in IHE Radiology Scheduled Workflow (SWF) Profile • Transaction Supported - Required • Patient Identity Feed [ITI-8] (as sender) Interoperability Strategy Workshop

10. Patient Identifier Cross-referencing for MPIActors Patient Identifier Cross-reference Consumer • Definition • Requires information about patient identifiers in other domains • Requests patient identifier information from Patient Identifier Cross-reference Manager • Transaction Supported - Required • PIX Query [ITI-9] (as sender) • Transaction Supported - Optional • PIX Update Notification [ITI-10] (as receiver) Interoperability Strategy Workshop

11. Patient Identifier Cross-referencing for MPIActors Patient Identifier Cross-reference Manager • Definition • Serves a well-defined set of Patient Identifier Domains • Receives patient identifier information from Patient Identity Source Actors • Manages cross-referencing of identifiers across domains • Transactions Supported - Required • Patient Identity Feed [ITI-8] (as receiver) • PIX Query [ITI-9] (as receiver) • PIX Update Notification [ITI-10] (as sender) Interoperability Strategy Workshop
