What to do when the native data has days_supply less than zero

CDM or THEMIS convention?

CDM

Summary of issues

There are cases where the native data has days_supply has less than zero for some drug exposures
This often indicates that it is unclear whether the person actually took the drug

Summary of answer

Any records in the native data with a days_supply less than zero should be dropped since the CDM is meant to represent things we are confident happened to the person
