So my initial thought was to map Gender in SNOMED (ID 4135376) then have this point to a custom table with our own codes since none of the standard vocabularies have the terms NAACCR uses for sex such as “Transsexual, natal male”
Added:
You don’t actually have to use USAGI. You could enter the data directly in Source_to_concept_map. But it would be good practice for mapping other codes which do not exist in the vocabularies.
Got it. I still have a lot to learn here for sure. So does OMOP in general not use the term “sex”? Gender and Sex are different terms in today’s world I believe. I see not mention of Sex int he Observation description.
