There are supposedly massive shortages in family practice, psychiatry and dermatology.
Nurse practitioners and PAs can independently practice in slightly less than half the states.
If the issue is medical knowledge, the NP/PA can go through the best medical education resources (Uworld, First Aid, Pathoma, Sketchy, Online MedEd etc) to get the core information that medical school teaches.
If it is dealing with complex problems or emergencies, the NP/PA can always refer those out to the doctor or emergency room.
So the question is: what is preventing this model from working?
Edit: I ask because a friend of mine just got booted from med school for non-academic reasons and he is either going to: 1. Go carib or 2. Do NP. Both would cost around the same, but NP would take more time even going through the accelerated programs.
