Description

OMOP Common Data Model (CDM) Concept Ancestor The CONCEPT_ANCESTOR table contains records that define the inferred hierarchical relationships between all standard concepts. The concept ancestor table is fully derived from the concept, CONCEPT_RELATIONSHIP, and relationship tables, whereby all ancestor-descendant relationships can be inferred from traversing all parent-child relationships between standard concepts. The concept ancestor table includes records for all parent-child relationships, as well as grandparent-grandchild relationships and additional levels of lineage. The concept ancestor table enables efficient identification of multi-step hierarchical relationships, such as branded drugs that fall within a therapeutic class or specific diagnosis that are classified within a particular system organ class. OMOP Common Data Model Specifications Version 5.0 The Observational Medical Outcomes Partnership (OMOP) was a public-private partnership established to inform the appropriate use of observational healthcare databases for studying the effects of medical products. © 2014 Observational Health Data Sciences and Informatics This work is based on work by the Observational Medical Outcomes Partnership (OMOP) and used under license from the FNIH at http://omop.fnih.org/publiclicense.
