Naming Systems

The following published Naming Systems are for use within Wales.

There are several namespaces used throughout this guide that are UK based which can be found on the UK Naming Systems page. These are not maintained by NHS Wales.

This includes a range of OIDs (Object Identifiers) defined by HL7 UK outside of the FHIR specification, which can be found on their OID Catalogue page.

NHS Wales OIDs and Namespaces

The Welsh Reference and Terminology Services team in Digital Health and Care Wales are responsible for the creation of namespaces and OIDs for NHS Wales systems. If you require one to be created please contact them via email at DHCW.WRTSServiceAccount@wales.nhs.uk.

As there are several hundred systems currently registered with OIDs it has been decided that they will not all be added as naming systems. To be pragmatic, we have added the most used, high-level system identifiers shared between systems. Please remember that identifiers are extensible so you are not limited to only referencing the below namespaces. Further information can be found on the Naming Systems Design page.

The following table displays all NHS Wales Naming Systems for each top level organisation - Health Board, Trust, or Special Health Authority.
