Hi Adam
We have discussed this for D:A
as well but did not find it feasable. One reason is that, for example in Switzerland the doctors are not supposed to prescribe brand-names of drugs, but the name of the substance. The pharmacist can then discuss with the patient whether he wants the original brand (normally at a higher price) or (one of) the available generics. So, the treating doctor or study nurse don't actually know which brand name the patient finally received. The above procedure may differ between clinics as some (few!) have ART drugs on stock in the clinic and know what the patient gets.
