CONCEPT_SYNONYM table

The CDM documentation is now being housed on github. The most recent release is v5.2

The CONCEPT_SYNONYM table is used to store alternate names and descriptions for Concepts.

FieldRequiredTypeDescription
concept_idYesIntegerA foreign key to the Concept in the CONCEPT table.
concept_synonym_nameYesvarchar(1000)The alternative name for the Concept.
language_concept_idYesintegerA foreign key to a Concept representing the language.

Conventions

  • The concept_name field contains a valid Synonym of a concept, including the description in the concept_name itself. I.e. each Concept has at least one Synonym in the CONCEPT_SYNONYM table. As an example, for a SNOMED-CT Concept, if the fully specified name is stored as the concept_name of the CONCEPT table, then the Preferred Term and Synonyms associated with the Concept are stored in the CONCEPT_SYNONYM table.
  • Only Synonyms that are active and current are stored in the CONCEPT_SYNONYM table. Tracking synonym/description history and mapping of obsolete synonyms to current Concepts/Synonyms is out of scope for the Standard Vocabularies.
  • Currently, only English Synonyms are included.
