Drug_exposure_end_date when verbatim_end_date and days_supply are misaligned #87

Closed clairblacketer closed 6 months ago

clairblacketer commented 7 months ago

What to do when the verbatim_end_date and days_supply are misaligned

CDM or THEMIS convention?

THEMIS

Summary of issues

Drug_exposure_end_date is mandatory
There are times when the days_supply of the intended dose is different than the time the patient actually took the drug
There is a question on how the days supply and drug_exposure_end_date should be populated in these cases. Should days_supply be shortened to reflect the time the patient actually took the drug? Should drug_exposure_end_date reflect the verbatim_end_date or days_supply?

Summary of answer

verbatim_end_date should reflect (to the best knowledge) the time that the patient was exposed to the drug
Verbatim_end_date should also be mapped to drug_exposure_end_date
days_supply should reflect the intent of the provider, even if the patient did not take the drug for that long, it should not be changed
