Somehow NPs and MAs are unable to do this - or so say doctors, ex-doctors, and family members on this thread.
Because midlevels are not trained enough to know that something that appears to be mild may be something more serious. However, if they get autonomy from supervision, then they better have some good malpractice insurance and not rely on a supervising physician to train them.
I knew a new NP grad who was hoping at her new job that the MD would train her in that specialty. That is crazy. If you graduate from a program, you should be able to effectively treat patients without relying on physicians to train you.
