201601 FHIR Terminology Services

FHIR Terminology Services

Submitting WG/Project/Implementer Group

FHIR Management Group (FMG)

Justification

The FHIR specification includes support for the provision of a terminology service - that is, a service that lets healthcare applications make use of codes and value sets without having to become experts in the fine details of the value set resource, and the underlying code systems.

Proposed Track Lead

Coordinator: Rob Hausam (There is a dedicated skype chat for terminology services - Contact Rob to be included - skype id rhausam)

Roles

FHIR Terminology Server

For service providers, implement the following operations from http://hl7.org/fhir/terminology-service.html:

• $expand
• $validate-code (note: there's a set of typos on the terminology service page where this operation is called "validate" but its actually "validate-code" - editorial oversight)
• $lookup
• $translate (note: there's a typo on the terminology service page where the example has '$validate' not '$translate')

Service providers are not required to implement all this functionality - it's a lot to do. For new implementers, start at the top and work down (generally)

FHIR Terminology Client Consumer

Any one of

• do a value set expansion of one of the value sets in the spec
• validate a code using the spec against a FHIR value set, a v2 value set, or LOINC or snomed CT
• look up a display for a code (most appropriate for v2/FHIR conversion)

At least one server supports all these operations (http://fhir2.healthintersections.com.au). Other servers, including the Apelon server (http://fhir.ext.apelon.com:8081/DtsOnFhirDemo) will support some of those operations
