Dont read to much into it if you see doctors with pens or other marked stuff. They use the pens because you get them for free and day to day so many pens get lost in a hospital. You wouldnt buy your own pens if they get lost anyways and you have tons of free ones already lying around. Of course I cant speak for everybody but from my experience (med student and my father is a doctor too) most doctors look carefully into what to prescribe. Not to mention that (at least in Europe) the times of expensive paid "conferences" (read: holidays) and such are mostly over. My dad still remembers getting paid first class flights to conferences in the US but today it's pretty much pay for yourself, even if you give a speech.
