We are mapping a procedures vocabulary (NOMESCO finnish version) to the OMOP.
We were mapping to SNOMED, but we now noticed that thera are other standard vocabulaires (selecting in Athena: “Standard” & domain=“procedure” & “valid” -> vocabularies = ICD10PCS, OPCS4, …).
How to porceed ?
a) Map code to the closest SNOMED even if loosing some info on the concept
b) try to map to SNOMED unless there is a more specific match in any of the other vocabularies (in that case which one to look first)
c) map to the best matching concept, it does not matther what vocabulary it is
