Purpose and Scope

Usage Type :    
Usage Description :    
In Release Format 2 (RF2) the realm description refset is the only way to determine the preferred description for a given realm. In RF1 this is an alternative to the combination of description tables and language subsets which are applied in accordance with the Technical Implementation Guide (TIG) and UK guidance. The table conforms to the specification described in section Realm Description Subset Members Table in the IHTSDO-published ‘SNOMED CT Release Format 1 Guide’. The ‘Pharmacy part’ specifies UK Description preferences for content beneath the following SNOMED CT top-level concepts: 373873005 | Pharmaceutical / biologic product (product) 105590001 | Substance (substance) 260787004 | Physical object (physical object) 362981000 | Qualifier value (qualifier value) Description preferences for all other components of SNOMED CT are specified by this ‘Clinical part’. Complete coverage of Description preferences therefore requires member data from the ‘Pharmacy part’ and ‘Clinical Part’ to be merged, including a dependency on the ‘Pharmacy Part’ to specify Description preferences for Concepts published and maintained in ‘Clinical’ chapters (e.g. ‘Substances’ and ‘Qualifier values’). In order to access all descriptions referenced this way – which include some from the UK Drug extension – it is necessary to load content from both UK Drug and UK Clinical Descriptions files (and, if used, corresponding Keys files). The NHS Realm Description subset will be released as part of both the bi-annual releases and the four weekly SNOMED CT UK Drug Extension releases (Pharmacy part).
