Thats complete Bull Sh... I dont know why people keep quoting that stupid phrase which was started by a non-physician for self gratification. The long coat and liscense comes with graduation as does alot of responsibility that you simply do not have as a med student. You are not looked on by attendings or patients as a med student and should never think of yourself as one or let others do that either. When in your opinion Socute are physicians physicians? After residency? Fellowship? That is complete crap.
I agree learn from whoever you can because plenty of people that are not MDs have something to teach you out of pure experience alone. But I would never go to a place that my primary supervisors are non-physicians. This is not out of spite or a superiority complex, But a place that the attendings and other senior residents dont have the time or desire to teach is not where you should want to be.
Ill be a CA1 this july. I would love to learn all I can from a CRNA. I have no issues admitting that at my current level they know more than I do. But I should not accept that the CRNA is my only source of knowledge or experience to draw upon for my education either.
A Non-physician has no business being the primary supervisor of a physician.
