Typically, if we know our data is complete through the end of 2018 then we don’t want event dates past Dec 31, 2018.
However, in many cases we are calculating the drug_exposure_end_date from the start date + days_supply. It’s possible these can pour into the future. Should we cap the dates with Dec 31, 2018 or should we make an exception for drug_exposure_end_date and allow it to go into the future?
If there’s a THEMIS or achilles rule for this I’d love to know what it is. Thanks!
