Where can we find relationships (links) between conditions, procedures and drugs? Is this something that’s in the vocabulary or a separate mapping challenge?
It is in the vocabulary (CONCEPT_RELATIONSHIP), but it really isn’t. Those associations are typically the result of the OHDSI research, not the input. But some source vocabs provide that information, such as SNOMED.
Thanks @Christian_Reich, does it mean that all consumers of the CDM vocabulary end up creating their own layer of concept relationships (associations/links) as per their own need/use case? Is this the current practice?
