Have you ever seen those brochures and flyers in the waiting room (and sometimes even the exam room)? Those are almost entirely supplied to the practice by pharma reps. Every U.S. doctor's office I've been in for the last four decades has been full of them.
Not to say that you had a very unique set of experiences but having been in many doctors offices and worked in a number, in the US there are generally brochures, pamphlets, pens, note pads, and the worst of all TV SCREENS advertising pharma crap.
The only place I haven’t seen brochures is my direct patient contract doctor (concierge) and even then he has natural herbal supplements for various things.
So just saying your experience is atypical. But it sounds like a dream.
Curious, are there any references? I have seen zero. Of course, I see tons of ads on TV so if the Dr.'s office has TV on, that may be one source. But I am curious about ads outside of the TV, haven't any like that in a Dr's office.
It only takes one person's evidence to prove your generalization wrong. My last visit to a podiatrist had dozens of ads on the walls and television that was airing nonstop commercials for medical products. Nothing makes for a better captive audience than excruciatingly long wait times.
