You have the players mixed up here a little.
The most coercive player is medicare through their payment system the goal of which is to pay as little as possible for as much as they can wring out of you as a provider.
Medicare establishes care guidelines and mandates compliance through their “Quality” system, if you dont do what they say you get docked. No appeal.
Those guidelines are developed by the bureaucrats with advice from advisory panels made up of experts in the field but the bureaucrats are not bound to follow the advice of the panel. There may be reps from pharma on the panel. Obviously pharma has avenues to influence those guidelines.
If you think that any lowly medical student or resident physician has any time to be indoctrinated by pharma you are sadly mistaken, they are just trying to survive working 80-100 hrs a week and avoid being in the line of fire by an attending on rounds. They are happy that a pharm rep may show up and buy lunch for a conference some noon but thats about the extent of pharmas influence on an in training physician.
Want to blame someone for most of the problems in health care today, look at the feds both the senators and reps as well as the bureaucrats at HHS.
