1 Sept 13-15, 2004IHE Interoperability Workshop 1 Integrating the Healthcare Enterprise Patient Identifier Cross-referencing for MPI (PIX) Profile Mike Henderson Eastern Informatics, Inc. Co-chair, IHE IT Infrastructure Technical Committee

2 Sept 13-15, 2004IHE Interoperability Workshop 2 IHE IT Infrastructure 5 Integration Profiles Enterprise User Authentication Provide users a single name and centralized authentication process across all systems Enterprise User Authentication Provide users a single name and centralized authentication process across all systems Retrieve Information for Display Access a patients clinical information and documents in a format ready to be presented to the requesting user Retrieve Information for Display Access a patients clinical information and documents in a format ready to be presented to the requesting user Synchronize multiple applications on a desktop to the same patient Patient Synchronized Applications Synchronize multiple applications on a desktop to the same patient Patient Synchronized Applications Consistent Time Coordinate time across networked systems Consistent Time Coordinate time across networked systems Patient Identifier Cross-referencing for MPI Map patient identifiers across independent identification domains Patient Identifier Cross-referencing for MPI Map patient identifiers across independent identification domains

3 Sept 13-15, 2004IHE Interoperability Workshop 3 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 domains 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

4 Sept 13-15, 2004IHE Interoperability Workshop 4 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

5 Sept 13-15, 2004IHE Interoperability Workshop 5 Patient Identifier Cross-referencing for MPI Transaction Diagram

6 Sept 13-15, 2004IHE Interoperability Workshop 6 Patient Identifier Cross-referencing for MPI Process Flow Showing ID Domains & Transactions

7 Sept 13-15, 2004IHE Interoperability Workshop 7 Patient Identifier Cross-referencing for MPI B:X456 C: 2RT Identity Patient Cross References B:X456 C: ?

8 Sept 13-15, 2004IHE Interoperability Workshop 8 Patient Identifier Cross-referencing for MPI Standards 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)

9 Sept 13-15, 2004IHE Interoperability Workshop 9 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)

10 Sept 13-15, 2004IHE Interoperability Workshop 10 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)

11 Sept 13-15, 2004IHE Interoperability Workshop 11 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)

12 Sept 13-15, 2004IHE Interoperability Workshop 12 PIX Integration Profile & MPI The typical view Patient Identification Domain C Patient Identity Cross- reference Manager Patient Identification Domain A (Master Domain) Patient Identification Domain B Master (A) Patient Identity Source Master Patient Index
