Reference Set Tools allow implementers to create and maintain subsets of SNOMED CT codes for a specific use case.
SNOMED CT subsets are an important resource in many implementations. They allow sets of SNOMED components to be grouped together, to support specific use cases, e.g. for data entry of diagnoses for a clinical specialty, for prioritisation of translations, and for data analytics queries. For example, in HL7 FHIR specifications, SNOMED CT value sets are specified in the terminology binding of relevant coded data elements.
Please note that:
- A SNOMED CT subset is a set of SNOMED CT components from a particular SNOMED CT edition.
- A SNOMED CT reference set is a standard format for maintaining and distributing a set of references to SNOMED CT components.
- A SNOMED CT value set is a set of valid concepts or expressions intended to constrain the permissible content for a particular use (e.g. data entry into a particular field).
An implementation requirement for SNOMED CT subsets can be satisfied by tools that help users to create generic SNOMED CT subsets, standard RF2 reference sets, or HL7 value sets. The choice of tooling will depend on the implementation artefacts required. For example, a SNOMED CT terminology server may require a SNOMED CT RF2 reference set format.
SNOMED International Reference Set Tool
SNOMED
This tool is maintained by SNOMED International and is used to maintain Reference Sets and Translations for many national extensions.
The features related to Refset Authoring tasks include:
- Creation of Extensional and Intensional Simple Type Reference Sets
- Adding members by direct selection, by uploading flat files, or by specifying queries
- Maintenance tasks related to the update to new releases of dependencies
- Collaborative workflow for content revisions
- Refset export for publication
- Management of refset metadata
- Refset directory
