Document Metadata based Access using FHIR – Analysis Cont’d
6
• Document Handling Resources
• Document Reference (Reference to existing XDS or other documents)
• Document Manifest (Collection of Document References)
• Composition (To compose documents)
• Bundles and Tags (To provide list of documents, security labels and metadata using tags)
Document Metadata based Access using FHIR – Analysis Cont’d
7
• Adoption of FHIR for DAF will require at a minimum
• Creation of a Profile or use the existing FHIR XDS profile for Document access using Document Reference and Document Manifest • FHIR XDS profile will have to be analyzed to
determine how well it maps to existing XDS infrastructure
• Create a Profile for using the Document Composition resource as appropriate
Document Metadata based Access using MHD – Analysis
8
MHD profile supports the following transactions which are relevant to DAF
•Get Document Dossier – This transaction is used to get the metadata related to a particular Document Entry.
•Find Document Dossiers – This transaction is used to provide parameterized queries that result in a list of Document Entries.
•Get Document – This transaction is used to get a single document.
Document Metadata based Access using MHD – Analysis Cont’d
9
• IHE is planning to align MHD to FHIR this year
• So the existing MHD profile is expected to change and be more aligned with FHIR
• Need to determine path forward in terms of MHD and FHIR and their potential alignment
• Will be having more discussions on this topic to understand timelines/alignment objectives and other aspects
