It looks like there may be two standard concept_ids for the concept ‘exerbation of asthma’.
I do see that the concept name in the omop concept table for (the active) SNOMED concept is ‘acute asthma’, however this is just the SNOMED preferred term for ‘exacerbation of asthma’.in the US edition.
Here’s the concept and synonyms from the SNOMED browser:
Was the omop extension concept added because there are concerns that ‘exacerbation of asthma’ and ‘acute asthma’ may not be semantically equivalent?
Any insight greatly appreciated.
