  3. 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 IHE Interoperability Workshop

  4. 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 IHE Interoperability Workshop

  8. Patient Identifier Cross-referencing for MPIStandards Used HL7 Version 2.5 • ADT Registration and Update Trigger Events • A01: inpatient admission • A04: outpatient registration • A05: pre-admission • A08: patient update • A40: merge patient • Queries for Corresponding Identifiers (ADT^Q23/K23) • Notification of Identifiers Lists Updates (ADT^A31) IHE Interoperability 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) IHE Interoperability Workshop

  10. 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) IHE Interoperability Workshop

  11. 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) IHE Interoperability Workshop
