Hi, We are trying to extract information from our clinical records into the OMOP CDM and have started with breast cancer as this is a domain our team is very familiar with. We are currently trying to map the various radiological procedures, and it seems logical to use SNOMED codes. Everything seems relatively straightforward until we get to screening studies (mammography, tomo and breast MRI). Some codes from Athena are here:
mammo and breast MRI are procedures as expected, but the screening studies are measurements for some reason. There may be no technical difference between a screening and a diagnostic mammogram but our source systems clearly differentiate between these and there is a big difference if you are trying to use the data to assess the efficacy of screening programs or to identify cohorts to use in developing AI algorithms so I don’t want to throw away this valuable information.
What is the rationale for putting the screening procedures under measurement? Is it something that can be changed? I saw an old thread from 2019 on the topic of mammography (@krfeeney , @mgurley , @Eduard_Korchmar @Mark_Danese ) but it didn’t address this point. I’m new to omop but it seems like it could cause end users problems if screening is in measurement but diagnostic mammography is in procedures. Thanks!
