Domains
Domains are OMOP-defined clinical entity categories that are defined for each Concept in the Standardized Vocabulary. A list of all Domains is stored in the DOMAIN table. In the CONCEPT table, the field domain_id of each Concept record determins the Domain the Concept belongs to.
All Standard and Classification Concepts (standard_concept = 'S' or 'C') have a unique Domain, while the non-standard Source Concepts (standard_concept = NULL) can have domain_id entries that represent combinations of the unique domain.
Domain assignments are done using a heuristic, which is different for each vocabulary. Most vocabularies have Concepts in one of few Domains, but some of them, like HCPCS or Read, are very broad. The assignment will follow the definition of each Domain (see below), but for some of the categories the assignment can be ambiguous. For these cases, in the OMOP Standardized Vocabulary we use the following rules:
