    3. August 18, 2005 IHE Technical Webinar 3 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)

    4. August 18, 2005 IHE Technical Webinar 4 Patient Demographics Query Use Cases

    5. August 18, 2005 IHE Technical Webinar 5 Patient Demographics Query Abstract / Scope Allow quick retrieval of a patient list including patient names, identifiers, contacts, and optionally also visit information Enable selection of correct patient when full identification data may not be available Limits access to only a subset of demographic and visit information

    6. August 18, 2005 IHE Technical Webinar 6 Patient Demographics Query Value Proposition Enables diverse systems and devices to access patient information on demand Participants that do not need continual synchronization of patient registration information Devices that cannot participate in monitoring of ADT feeds, e.g.: Small-footprint devices Low-memory devices

    7. August 18, 2005 IHE Technical Webinar 7 Patient Demographics Query Value Proposition (cont’d) Allow search on full or partial data Allow the client to designate the information source (with the corresponding Patient ID domain) for a query request Allows use of matching algorithm (e.g., soundex) to find near matches Particular algorithm and operation are out of the scope of IHE Technical Framework

    9. August 18, 2005 IHE Technical Webinar 9 Patient Demographics Query Model: Patient Information Sources and Patient Information Supplier A PDQ request is always served in one Source, which patient records are identified in one Domain. The Supplier may know Patient ID of the found records in other domains. The Supplier may support multiple Sources for PDQ requests – the client selects which source is to be searched.

    10. August 18, 2005 IHE Technical Webinar 10 Patient Demographics Query Model: Multiple Patient Information Sources and Patient ID Domains

    11. August 18, 2005 IHE Technical Webinar 11 Patient Demographics Query Actors Patient Demographics Consumer Definition Requestor of patient demographic (and optionally also current visit) information Allows user to associate information with a patient at the point of care Transaction Supported – Required Patient Demographics Query (as sender) Transaction Supported – Optional Patient Demographics and Visit Query (as sender)

    12. August 18, 2005 IHE Technical Webinar 12 Patient Demographics Query Actors Patient Demographics Supplier Definition Has access to Repository of patient information that can be searched on demographic (and optionally also visit-related) fields Transaction Supported – Required Patient Demographics Query (as receiver) Transaction Supported – Optional Patient Demographics and Visit Query (as receiver)

    16. August 18, 2005 IHE Technical Webinar 16 Patient Demographics Query Operations Patient Demographics Query User enters full or partial demographic information (e.g., partial last name and first initial) for patients of interest Application associated with Patient Demographics Consumer sends HL7 QBP^Q22 to Patient Demographics Supplier to find matching information May request specific domains from which to return identifier information

    17. August 18, 2005 IHE Technical Webinar 17 Patient Demographics Query Operations (Cont’d) Patient Demographics Response – Patient Demographics Supplier recognizes Patient Identifier Domain(s) requested by Patient Demographics Consumer: Patient Demographics Supplier returns HL7 message with list of matches (if any) to Patient Demographics Consumer Demographic information in HL7 PID and PD1 segments From demographic source associated with receiving application If no matches found, returns code NF (not found) in QAK-2-Query Status Application associated with Patient Demographics Consumer builds pick list from which user may select Matches within level of tolerance defined by user Query allows any matching algorithm the supplier may choose to make available

    18. August 18, 2005 IHE Technical Webinar 18 Patient Demographics Query Operations (cont’d) Patient Demographics Response – Patient Demographics Supplier does not recognize Patient Identifier Domain(s) requested by Patient Demographics Consumer: Patient Demographics Supplier returns code AE (application error) to Patient Demographics Consumer in the following fields MSA-1-Acknowledgment Code QAK-2-Query Response Status Patient Demographics Supplier returns one ERR segment to Patient Demographics Consumer for each unrecognized domain

    19. August 18, 2005 IHE Technical Webinar 19 Transaction ITI-22: Patient Demographics and Visit Query

    20. August 18, 2005 IHE Technical Webinar 20 Patient Demographics and Visit Query Operations Patient Demographics and Visit Query User enters full or partial demographic/visit information (e.g., room/bed number) for patients of interest Application associated with Patient Demographics Consumer sends HL7 QBP^ZV1 to Patient Demographics Supplier to find matching information May request specific domains from which to return identifier information

    21. August 18, 2005 IHE Technical Webinar 21 Patient Demographics and Visit Query Operations (cont’d) Patient Demographics and Visit Response – Patient Demographics Supplier recognizes Patient Identifier Domains requested by Patient Demographics Consumer: Patient Demographics Supplier returns HL7 RSP^ZV2 message with list of matches to Patient Demographics Consumer Demographic information in HL7 PID and PD1 segments Visit information in PV1 and PV2 segments From demographic source associated with receiving application If no matches found, returns code NF (not found) in QAK-2-Query Status Application associated with Patient Demographics Consumer builds pick list from which user may select

    22. August 18, 2005 IHE Technical Webinar 22 Patient Demographics and Visit Query Operations (cont’d) Patient Demographics and Visit Response – Patient Demographics Supplier does not recognize Patient Identifier Domain(s) requested by Patient Demographics Consumer: Patient Demographics Supplier returns code AE (application error) to Patient Demographics Consumer in the following fields MSA-1-Acknowledgment Code QAK-2-Query Response Status Patient Demographics Supplier returns one ERR segment to Patient Demographics Consumer for each unrecognized domain
