Dang. Like what?
Also what changed as a result of the merger?
As a DO, you CAN get into a FM/PM&R residecy program to Stanford, Yale, and Duke. HOWEVER, if you are considering IM or surgery (two specialities that have a very high rate of segway into academics) you will be locked out of most top tier programs. For IM this would includes places like MGH, Northwestern, UFlorida, UChicago (The actual categorical residency affiliate with Pritzker, not NorthShore), UCSD, UCLA (Ronald Reagan, Harbor is still likely), UCSF (UCSF-Fresno is doable), BMC, BWH, NYU, Icahn, Einstein Montefiore, Vanderbilt. For surgery, a good majority of ACGME programs that are part of academic med centers are locked out for DO's. I know KP/Arrowhead Regional in CA consistently accepts DO's into their Neurosurg but again, it's not a university medical center. For now this is the case.
Merger: DO's are still eligibe for ACGME fellowships (if AOA didn't agree we would have been barred out), AOA accredited programs must apply for ACGME accred or be shut down entirely. A good amount of DO programs will shut down but for the better. The result: A better standard for GME. Probably A bit more competition for certain surgical programs.
Since this thread has been posted time and time again. It'll be closed.
