NHS England FHIR Implementation Guide (deprecated)

Important Announcement regarding this Implementation Guide
  • As of 04/10/2023, this implementation guide has been deprecated and all development on the legacy NHS England FHIR Implementation Guide assets has ceased.
  • Therefore, vendors looking to start new implementations or looking to update existing implementations should use the new NHS England Implementation Guide. Vendors continuing to implement legacy NHS England FHIR Implementation Guide based solutions do so at their own risk and on the understanding that no maintenance or support will be available.


This section details the policy for FHIR Implementations using FHIR version R4 within NHS Digital. It is currently proposed that the guidance contained here will also apply to FHIR version R5 and onwards wherever practical and allowable by the FHIR standard.

It applies to NHS Digital assets derived from UK Core where conformance to UK Core is claimed or required.

The policy for R4 has major differences to the STU3 policy due to the development process changing to give a closer alignment with NHS Data Dictionary, NHS Supplier Frameworks, the US Core and the FHIR standard for R4.
