ISO/PAS 24305:2025: Guidelines for Implementing HL7 FHIR with International Standards

Details

ISO/PAS 24305:2025 provides comprehensive guidance on combining four complementary international standards for developers of health ICT systems and infrastructures. These standards include HL7 FHIR, ISO 13940:2015, ISO 13606-1:2019, and ISO 13606-3:2019. The document defines specific mappings between these standards, such as between ISO 13940 and HL7 FHIR in both directions, and proposes the content of an HL7 FHIR profile corresponding to the ISO 13606-1:2019 “COMPOSITION” class. Furthermore, it provides guidance and worked examples for mapping between ISO 13606-3 Reference Archetypes and ISO 13940/FHIR. Crucially, the standard also summarizes the extent to which a source concept is broader or narrower than its best fit target concept, highlighting potential mapping issues arising from differing representation capabilities across standards. This comprehensive approach ensures that developers have detailed technical guidance for achieving robust international interoperability in healthcare data exchange.
