Wales FHIR Implementation Guide v1.0.0 STU1

Important: This is the v1.0.0 Standard for Trial use (STU1) release of the Data Standards Wales FHIR Implementation Guide. There is a mixture of active and draft FHIR resources which have been published following the inaugural ballot process. The active profiles have been scrutinised by the FHIR Task & Finish group and they may be developed further in future iterations. Active profiles can be used for implementation and we would encourage anyone beginning development to inform the Interoperability Delivery Team. While the profiles have some rigidity, the intention is for development to be flexible to the needs of system owners throughout NHS Wales.

Some profiles are also provided in an experimental state which have not undergone a more thorough review cycle. The latter are liable to change regularly and should not be expected to remain stable until they move to draft. The assets contained in this implementation guide may not make it to the next major version following the results of balloting.


The guidance contains:

  • FHIR resource profiles and extensions.
  • FHIR terminology components including ValueSets, CodeSystems and ConceptMaps.
  • Example FHIR resources.
  • Other general guidance useful to FHIR implementers in Wales.

Project Description and Scope

This Implementation Guide contains the HL7 FHIR R4 standards for use by Health and Care organisations in Wales.
