I am responsible for writing the 2020 CTSA Common Metrics queries for OMOP/BigQuery along with @rtmill and @apeshansky for other DBMSs. One metric is the number of encounters with at least one vital sign, which I am interpreting as any form of BP, HR, RR, and/or Temperature measurement. My ask: Is there an already established concept set for these common measures and if not, any advice for how to get a “good enough” set.
I did not find any relevant concept sets defined in atlas.ohdsi.org. or atlas-covid19.ohdsi.org. Using ATHENA, I see that LOINC has a classification concept (concept_id: 1003157) that incorporates lower-level LOINC Vitals measurements. But the 1263 descendant concepts from concept_ancestor far exceeds BP/HR/RR/T (e.g. cardiac index, LVEDP, O2 sat), even after limiting to only standard concepts and measurement domain_id.
Seeking advice how to proceed in the most efficient way.
