How is it suggested one code a question/term for concomitant medication? Do you code it as the specific drug and also use the term concomitant? We specifically need to track these data vs the actual study medication.
That’s a very clinical trial type question, where there is one study drugs, and all the others are concomittant, or “also rans”. In observational data, all drugs are the same.
So now what? I start coding using CDISC SDTM?
