Clinical Metadata Exploration Ontology (CMEO) clinical data category subset is about clinical event record adverse event record A clinical event record that documents an untoward or harmful occurrence in a patient following a medical intervention (such as the administration of a drug, a procedure, or the use of a medical device), whether or not judged to be caused by it, and that is about the corresponding adverse-event process. Modelled in CMEO as an information/record layer term, not the occurrent itself. It 'is about' the underlying process (inherited from 'clinical event') and is cross-referenced via skos:exactMatch to OAE:0000001 'adverse event'. CMEO keeps its own IRI because it is used as an event/outcome descriptor in the metadata scope rather than imported as an OAE pathological process. adverse event adverse event
