FHIR ValueSet: Intersection of Referenced Item Category and Document Class Codes
Intersection of referenced-item-category and document-classcodes
Summary
A technical specification for HL7 FHIR's reference structure has been published. Specifically, it defines the set of codes common to two ValueSets: 'Referenced Item Category' and 'Document Class'. This provides foundational information for handling both referenced items and document classification in medical data.

This content is based on a technical reference page within the HL7 FHIR specification concerning ValueSets. It details an Intersection ValueSet, which defines codes common to two distinct ValueSets: 'Referenced Item Category' (http://hl7.org/fhir/ValueSet/referenced-item-category) and 'Document Class' (http://hl7.org/fhir/ValueSet/document-classcodes). This specification is crucial in medical information systems where it is necessary to handle not only the classification of a reference item but also the contextual information regarding what type of document that data belongs to. For example, it allows for clear linking of whether a specific measured value (Referenced Item) corresponds to a particular class of clinical record (Document Class). FHIR is a standard designed to enhance interoperability in medical data. Defining such common sets ensures consistency across different data elements and classification systems, forming a foundation for handling complex and practical clinical workflows. In Japan, where refining data structures and ensuring interoperability are urgent challenges for electronic health records and regional care networks, detailed ValueSet definitions at the FHIR level hold extremely high relevance.
