Yes, that's part of it. Demands on doctors (in the US at least) are absolutely insane. Keeping up to date on the relevant literature for a single specialty would require something like 27 hours per day of reading, most doctors cannot afford to see a patient for more than 15 minutes at a time because they need to get through so many consultations per day, and then they have to argue with insurance companies much the same way (but at dramatically higher frequency) that patients do.
