Query Concept Maps

This transaction allows a PoS, or any OHIE component, to access terminological information in the terminology service to query for Concept Maps. A typical example would be to request the set of Concept Maps whose target Code System is SNOMED CT. Mapping is frequently required when patient data is collected using Concepts/Codes from one Code System but the data must be reported or aggregated, say for decision support, in a different Code System. The set of such associated Concepts, usually for a specific use-case, are stored in the Terminology Service in a FHIR Resource called a ConceptMap.
Both external systems and systems inside the HIE may perform this transaction directly with the TS. The sequence diagram below shows the steps that occur for a system using this transaction.

Assumptions and Prerequisites
The required Concept Maps have been preloaded into the Terminology Service.
Actors
  • PoS - The point-of-service system or other HIE component that is that is querying for Concept Maps.
  • TS - Stores the curated, official version of the Concept Maps for the health system.

1
Query Concept Map request
The Concept Map search request is triggered by a PoS or other HIE component.
Input: A set of FHIR search parameters.
FHIR ConceptMap Resource
2
Query Concept Map response
The response is sent back to the requesting system.
Output: a Bundle of ConceptMap Resources that satisfy the search parameters.
