Hello,
So I have 2001 Ethnic Category Census data which are classified as “Non-Standard” but “Valid”.
These can be found here in Athena if anyone wants to have a look at them …
https://athena.ohdsi.org/search-terms/terms?vocabulary=SNOMED&page=1&pageSize=500&query=“2001+census”
I know I need to map to “standard” Ethnic category codes, but has this been done anywhere already? Or would I need to create my own mappings?
