The Technical Standards, defining the exchange of medicines, allergies, and intolerances data, are published within the Wales FHIR® Implementation Guide. These standards are defined as sets of FHIR® Profiles for medications, allergies, and intolerances, which are provided along with example FHIR® Resources which illustrate and aid understanding of the standards.
The latest version of the Wales FHIR® Implementation Guide should be accessed via the Version History page (https://simplifier.net/guide/wales-fhir-implementation-guide-version-history). Specific guidance for Allergy and Medication is accessible via the Home page of the Wales FHIR® Implementation Guide2.
The NHS Wales FHIR® standards are derived from the latest release of HL7® FHIR® UK Core which provides additional specification and guidance for use of HL7® FHIR® within the four UK nations. These standards have been subject to the HL7® UK ballot process.
In addition, the Standard also utilises codes from the SNOMED CT UK Edition (https://termbrowser.nhs.uk/) and Dictionary of Medicines and Devices (dm+d) (https://www.nhsbsa.nhs.uk/pharmacies-gp-practices-and-appliancecontractors/dictionary-medicines-and-devices-dmd).
Further Technical Standards in support of this DSCN are expected to be developed and published through the relevant assurance processes as the DMTP progresses. These changes will be managed in accordance with the change management process referred to in the Action Required section of this DSCN.
2 Some elements within the FHIR® Profiles for medications, allergies, and intolerances include resource references to FHIR® Profiles Data Standards Wales – Encounter, Location, Organization, Patient, Practitioner, and Practitioner Role.
