In USA, in pharmacy dispensation data - there is a concept of refills. A patient can get a prescription for a drug (e.g., lipid lowering drug) and make 3 trips to the pharmacy. First pick up of drug’s supply for January and then do refill 1 in February and refill 2 in March. (and than a new prescription with new 2 refills)
I wonder if in France, UK, Germany, Japan, Korea, XYZ county, there is even such a thing as refills? You simply get all 3 months in a single dispensation. Can you please describe your Rx data and if the concept/idea of refills is “in your Rx dispensation data” ? (tagging @Rijnbeek @MaximMoinat @Alexdavv @rwpark )
