We are currently working on mapping our source terms to OMOP standard terms. Though we always pick the right values for filters like ‘Domain’ and ‘Vocab’ and ‘Standard’, can you help us understand the importance of ‘Class’ column/field? Is there any guideline that you follow to map items like
for example, what’s the difference between 1 and 2 shown below and how will this impact our final analysis results?
- Drug (domain) -->Rxnorm (vocab) -->Ingredient (class)
- Drug(domain) --> Rxnorm -->Branded drug box
a) Am I right to understand that we are usually expected to map it to the broader term?
b) Should our mapping be dependent on the institution who carries out this omop project?
I mean will the mapping differ should the enduser be hospital or Pharmaceutical company?
Hospital will be interested to know about the patients whereas the pharamceutical company might want to know about the brands of drugs etc.
c) How accurate should our mapping be? What will be the drawback if we don’t pay attention to ‘Class’ field?
d) Do you have any standard filters that you follow, so that we can guide the end-users on how to do the mapping or it’s like kind of experimentation? we are doing this omop transformation for a hospital
Apologies, if my question is basic
