A) It's heading in that direction.
B) The mention of separate origin with convergent evolution is a valid point! As I have mentioned previously in other threads, Medicine in 2015 is NOT the same as it was in 1915 or 1890, hence the early proliferation of life-forms, err, doctrines in the practice of Medicine. How many of you know that Drexel start out as a merger between Hahnemann and another failed MD school? And that Hahnemann started out an a homeopathic medical school?? How many of you know that UCI started out as a DO school???? I foresee a time where the two degrees will merge. I'll probably be long retired or dead by that point.
So you see, evolution occurs right in front of our eyes. The negatives in this are two-fold:
1) The AOA persists in opening new schools, thinking that more DO grads is a good thing
2) VCOM, RVU, PCOM, CCOM, Touro and LECOM have realized that opening medical schools is a cash cow, but have no regard to the future of the profession, or the graduates they produce. My learned colleague
@22031 Alum's comment above about how one lousy student can poison the well for a school is very telling. It's 100% correct, but the people jumping on the branch campus bandwagon are unaware of this, or simply don't care.
C) By and large, medical education IS standardized for the first two years. The MD schools, since they almost all have access to teaching hospitals, can provide a more standardized 3rd/4th year education, and this is what PDs look for, especially for those beloved and highly lusted after competitive specialties.
D) As for standardized AND homogenous, I don't think that this will be possible given that there are many different avenues to teaching a doctor how to be a doctor, especially in the first two years. Classic Flexner discipline-based? Systems-based? PBL? Competency-based? TBL? Early clinical exposure? Roughly every 10-20 years, some genius at Harvard comes up with a curriculum change, and by Gawd, every medical school in the US has to follow suit! It sure becomes a pain in the ass for us Faculty.
One final note. With the return of the for-profit medical school, it wouldn't surprise me if hospitals or hospital chains get in the act of opening their own med schools. Ready supply of cheap labor and future staff and al that, if they can get over the mania of the "you need to see a patient every 15 minutes" business model.
