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) June 28-29, 2005 Interoperability Strategy Workshop

Patient Identifier Cross-referencing for MPI Abstract / 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 June 28-29, 2005 Interoperability Strategy Workshop

Patient Identifier Cross-referencing for MPI Value 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 June 28-29, 2005 Interoperability Strategy Workshop

Patient Identifier Cross-referencing for MPI Actors 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) June 28-29, 2005 Interoperability Strategy Workshop

Patient Identifier Cross-referencing for MPI Actors 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) June 28-29, 2005 Interoperability Strategy Workshop

Patient Identifier Cross-referencing for MPI Actors 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) June 28-29, 2005 Interoperability Strategy Workshop
