No as they can already get that from drug sales figures via the distribution suppliers like https://www.alliance-healthcare.co.uk/pharmacy-solutions/wholesale-distributors https://www.alliance-healthcare.co.uk/pharmacy-solutions/who... and few other players in the market who do all the logistics of supplying drugs to hospitals and pharmacies. I worked at Unichem (now alliance-healtcare) upon the system that would produce that data that other companies would buy. No patient specific - just volume of drugs for area's and with that, still happens today.
