Most medical operations have an army of people supporting physicians.

I used to work at a medical lab and there were transcriptionists, billing dept, a dept. for quality assurance of every report a doctor wrote, customer service, etc. Hospitals have all of that plus nurses (RNs, CNAs, etc.), physician assistants, and probably many others.

Part of the problem is how much paperwork/procedures/diagnostic reporting is legally mandated to be done by doctors. The other part is...money. Businesses want to/need to squeeze as much money out of the doctors and that requires seeing as many patients as possible.
