Data Access Framework (DAF) Technical Work Group March 5 th 2014
DAF Technical Work Group (Scope) 2 In Scope: – Leverage the IHE White Paper developed by IHE PCC outlining existing IHE profiles and their applicability to DAF – Identify additional standards/profiles that can be leveraged to meet the DAF (LDAF and Targeted) query use cases with a focus on modularity and substitutability – Identify the gaps in the existing standards/profiles to meet the use cases and requirements outlined – Development of implementation guides/API’s required for implementation of the use cases – Support DAF Pilot activities Out of Scope: – Creation of policies to enable queries Policies include consent, patient matching, disclosure requirements etc. – Identifying business processes and workflows required to enable queries.

DAF Abstract Model 4
DAF Queries for Document Metadata Based Access 5 Transactions/Queries required for DAF Find Patient Identifiers for Patient Demographics Find Document(s) based on Patient Identifiers Find Document(s) based on Patient Demographics Get Document(s) based on Document Identifiers Supply and Consume User Assertions to support security aspects of the query

Document Metadata based DAF Queries – Other Candidate Standards 7 Transport ? Security ? Content (Query Structure and Query Response Structure) ? Vocabularies ?
DAF Queries – Next Steps 8 Analyze any other potential candidate standards and their maturity for DAF Document Metadata based access Start identifying granular parts of the IHE profiles that would be required for DAF purposes Actual Transport/Security aspects Queries to support Optionality that needs to be removed Result structure for documents
