Data Access Framework (DAF) S&I Initiative Update June 19 th,

Overview (Recap) BlueButton initiatives enabled patients to access to their own data DAF is similar, except it is focused on enabling providers to access their patient’s data using modular and substitutable standards –Within their own Local Organization (Local DAF) –From another Targeted Organization (Targeted DAF) –Between multiple Organizations (Federated DAF – Future phases) 2

Challenges to Address Data Access Complexities include: –Ability to access data within and across organizations using standards –Ability to access patient’s data using document metadata paradigm Get latest Lab Report for a Patient so that I can check her HBA1C levels Get CCD’s for the last 3 years for a patient Get the last History and Physical Note for the patient –Ability to access patient’s data based on discrete data elements captured within a patient record Get latest lab report for a patient where HBA1C > 7% Get me all patients < 5 years who are due for an immunization Get me all patients > 75 years with HBA1C > 7% –Enable both Patient level (Local and Targeted ) and Population level data (Data about multiple patients – only for Local) 3

Out Of Scope DAF does not address the following: –Trust establishment between organizations for Targeted Query Could leverage all the trust work happening in Direct –Discovery of End Points for Targeted Query –Patient Matching rules and algorithms that organizations may implement –Policies that allow/dis-allow disclosure of patient data 4

Current State S&I/IHE PCC DAF White Paper –Describes how to use existing IHE profiles to meet DAF needs and identifies gaps that need to be filled (Both new profiles and change proposals) –Gaps being prioritized to inform upcoming IHE Planning Cycle. –Currently under Public Comment period S&I Document Metadata Based Access Work Group –Allows ability to access patient data using document metadata paradigm –Finished Candidate standards analysis –Creating an Implementation Guide around the standards S&I Data Element Based Access Work Group –Currently performing standards analysis –Completed FHIR, working on others identified by the community (HL7v2, QED, HQMF etc) S&I DAF Direct Transport WG (Community/Volunteer driven WG) –Working on a solution using all the content models from Document and Data Element Based Access Work Groups but changing the Transport from SOAP/HTTP to Direct/SMTP. 5

Document Metadata Based Access Overview 8 Query Requestor Query Responder Query Query Results Query Stacks Required SOAP and RESTful Query Stacks Required SOAP or RESTful DAF Queries Find Document(s) based on Patient Identifiers Find Document(s) based on Patient Demographics Get Document(s) based on Patient Identifiers Get Document(s) based on Patient Demographics Get Document(s) based on Document Identifiers Get Document(s) for multiple patients based on patient identifiers Find Patient Identifiers based on Patient Demographics Find Patient Demographics based on Patient Identifiers DAF Supporting Capabilities Provide message integrity and confidentiality of queries and results exchanged between the Query Requestor and the Query Responder Ability to provide user and system identities as necessary for authentication and authorization Ability to tag the queries and the query results with security metadata that will enable policy enforcement for query execution and data disclosure
