3. 306/18/2013 Pilot Administrivia This pilot is a community led pilot –Limited support provided by the ONC Apurva Dharia (ESAC) Jeanne Burton (Security Risk Solutions) Melissa Springer (HHS) In conjunction with DS4P bi-weekly return of an All Hands meeting Access to DS4P Wiki, teleconference, and calendar Meeting times: Tuesdays 11AM (ET) –Dial In: +1-650-479-3208 Access code: 662 197 169 URL: https://siframework1.webex.com/siframework1/onstage/g.php?t=a& d=662197169 https://siframework1.webex.com/siframework1/onstage/g.php?t=a& d=662197169

4. 406/18/2013 Scope of the Pilot 1. Define the exchange of HL7 CDA-compliant PCD between a data custodian and a PCD repository that includes a report on the outcome of the request back to the healthcare consumer. 2. Additional goal: use of identifiers that can uniquely identify the healthcare consumer and PCD repository used to report the outcome of the request back to the healthcare consumer by healthcare consumer’s provider and subsequent EHR custodians. 3. Stretch goal: use of the PCD repository as a proxy allowing direct authentication by the healthcare consumer to the provider, subsequently reducing correlation errors.

6. Functional Requirements Summary Precondition Functional Requirements –Document format for establishing authentication exchange * –Document format for exchange of repository account holder and HIO identifiers? (in proxy) * –Document format for clinical data request (NwHIN) Functional Requirements –Document format for requesting consent directive –Document format for returning consent directive –Document format for sending result of decision to consent directive repository Post-Condition Functional Requirements –Document format for exchange of repository location and account holder identifier to 2nd requestors associated with data [based on DS4P IG UC 3 as discussed 30APR2013] * = non-normative 06/18/20136

7. 7 Relevant Standards Standards from previous discussions: XCA and/or XDS.b (IHE) XUA (IHE) – IHE profile includes SAML (OASIS) XCPD (IHE) – not fully integrated into DS4P IG ATNA (IHE) – for returned audit of the release decision CDA r2 (HL7) – for PCD location in released clinical document – for format of the directive (includes XACML) XACML (OASIS) – specifically to PCD NwHIN specification ODD (IHE) - On-Demand Documents (Trial) Supplement Note: PCD (HL7) – just updated last WGM, will re-ballot 06/18/2013

8. Gap Analysis Initial gap analysis for discussion: 1.Single PCD can apply to multiple requests (must filter PCD) 2.Discovered XDS.b issues (XUA “participant” issue) 3.Interoperability of current PCD (HL7 PCD structure) 4.Interoperability of current PCD (XACML payload) 5.Gaps in PCD vocabulary (supporting granularity) 6.Returning repository location in the clinical data (extension) 7.Mapping ATNA protocol to use case (sufficient for user story?) 8.More attributes are required in request to PCD repository 9.XCPD caching issue can result in wrong attributes 10.Some attributes are missing or conflated 11.Attributes used in PCD exchange may have different meaning 06/18/20138

10. 1006/18/2013 Pilot Endpoint Functionality J-UT participants should initially support: CONNECT 4.1 base functionality CONNECT 4.1 Master Patient Index (MPI) CONNECT 4.1 XDS.b document repository CONNECT 4.1 test scripts Optional capability: CONNECT Universal Client (UC) GUI Future capability: Support ATNA logging Must be configurable to allow PKI set up

11. 11 J-UT Notional Architecture 06/18/2013 Initial goal: request/provide patient clinical document.

12. Implementation Update Current implementation status –CONNECT 4.1 suite installed –PKI infrastructure set up –Tested functionality: CONNECT MPI CONNECT XDS.b 4.1 document repository XCPD / XCA –CONNECT Universal Client (UC) GUI Required switch to Glassfish application server Jericho will make Document Custodian endpoint available 06/18/201312

13. 1306/18/2013 Completing Basic Infrastructure Additional steps required to complete Basic Infrastructure milestone Crosscheck each participant’s gateway Establish network connectivity between pilot participants –Custodian –Primary Requestor Re-Test Establish process for deploying code updates as development commences. Initiate development spirals for reference implementation

14. 1406/18/2013 Conformance Effort Create and track conformance against IG (with our additions) –Conformance statements tested –Conformance statements used –Increasing “utilized” number and tested/verified conformance statements Issues for discussion/resolution Items marked for discussion –Input from implementers Items marked “not applicable” –“hide” rows to resolve clutter Change, removal requested for some items –Discussion of pilot recommendations may be needed

15. 1506/18/2013 Crosscheck Approach

20. 20 Plan of Action Upon agreement of the participants the POA is: Identify the elements available from previous DS4P pilots Scope level of effort, decide on extended scenario Determine first draft of functional requirements Review standards available for returning information on requests Determine any gaps or extensions required in standards Stand up information holders and requestors Create XDS.b repository holding PCD Identify remaining pieces Document and update IG with results of our experience 06/18/2013

36. 36 Call for Pilot Team Members 05/14/2013 NameRoleOrganization David StaggsParticipantJericho Systems Corporation Michael FieldParticipantUT Austin HIT Lab

37. 3706/18/2013 Issues from Previous Call 1.Issues inherent in embedding PCD repository information Embedding PCD Repository information in clinical documents Providing a pointer to location is static (even if PCD dynamic) Can we meet goal by embedding query information? 2.Subsequent Custodian of Data should multicast query for PCD Provide broad information, specific to organization Provide unique PCD identifier in clinical document 3.Cover new use cases If PCD not found, multiple PCD found, or new repository 4.Build on previous pilots Most recent PCD, no de-confliction step considered

38. 3806/18/2013 Running Observations 1.XCA simplifies back-end implementation Although XDS.b is described in IHE documents, not required Many current examples of eHealth Exchange use XCA 2.On-Demand Documents Supplement NHIN has adopted the use of On-Demand Documents Updates XCA to use dynamically created documents Allows registration of content dynamically assembled 3.Audit record from custodian of release decision Previous pilots used unique message ID, not externalized 4.Creation of PCD on demand If PCD has sensitive data, should not give all information

39. 3906/18/2013 PCD Reference Information 1.How a PCD is referenced depends on your environmental assumptions XCA takes care of patient id mappings and lookups of remote service endpoint URLs Using XCA, reference of PCD is by home community ID Using plain XDS.b, reference of PCD is by patient ID and service endpoint URL 2.What is the impact of clinical document exchange architectures?

40. 4006/18/2013 Architecture Differences 1.eHealth Exchange using CONNECT Uses XCA for document queries Communities are connected with a service registry –If you are not in the service registry, you don’t exist Works well when you don’t know who has the information Typically requires MPI, XCA implementation, and a service registry. –Complex and expensive to manage the supporting systems

41. 4106/18/2013 Architecture Differences (cont) 2.DIRECT Uses XDR and XDM instead of XCA. –i.e. either a direct SOAP web service call over HTTPS (XDR) or over S/MIME (XDM) Works great when you are pushing a record to someone you know Requires minimal supporting software and systems 3.Summary What is the appropriate standard for exchanges with the PCD repository: XCA – or – XDR & XDM?

42. 4206/18/2013 PCD Reference Table

43. Using ATNA Mapping ATNA protocol to use case –ATNA protocol is based on syslog and consists of an XML payload Does the ATNA schema has the required data for our use case for directly interfacing with requesters: 05/14/201343
