Additionally PAs can prescribe many drugs in most states, but the supervising physician is ultimately responsible for the patients care.
Finally there are numerous subspecialties that simply aren’t available to PAs.
A PA degree only requires 2 years of post-bachelor training. An MD requires 4 years of medical school and a minimum of 3 years in residency (most specialties require 4, but some require more — e.g. 7 years for neurosurgery, or even more for oral & maxillofacial surgery since that also requires a 2-year DDS and a 6-year residency).
So 2 years for PA vs. between 7 and 11 for MD.
They are different from physicians, but they're still medical professionals.
I'm not sure I'd say that PAs are not "professionals" but I would say that they are only in a broader sense of the word.
Example?
No, it is Basil Besh who is the medical professional. Anna Watson is a physician assistant. Basil Besh is a doctor. Part of having your doctor's license is being subject to an oversight board of your peers. As a patient you can complain to this board and if the doctor cannot prove that he has provided adequate care, he can lose his very expensive livelihood.
They key here is that he has to justify himself to his peers, ie doctors who would look at the patient records and his notes and judge whether he provided a standard of care by calling or not calling an ambulance, etc. Randos on the internet speculating about patients they know nothing about is PR, not medicine.
The way you will know whether this story is real or another one of the endless Telsa hate pieces is that this guy will lose his license if it is real.
