Oh really now? Any evidence?
Anyways, I would not mention "osteopathic medicine." I used the same personal statement that AMCAS required. Talk about yourself and your interests, what have you done to develop these interests, how do you know medicine MAY be right for you, etc.
I applied to both MD and DO programs b/c my instate programs were MD. It does not matter at all. If you want to go into "osteopathic medicine" hold your horses until you get that secondary or bring it up in an interview. In the secondary, as far as I could remember, it was mainly an excuse to collect another $50-70 by asking almost the same things so I gave them almost the same things. In my interview, I was never asked "why DO?" However, I do know of other classmates who were. If you are asked that question, then that is the time to have your thoughts collected and give something unique, not some run-of-the-mill "I like the holistic approach shpeel" b/c it'll make you sound like a quack who knows nothing about medicine, nonetheless Osteopathic Medicine. There is nothing unique b/w MD and DO outside of the OMT from my experience so far. Yes, maybe MDs in the past weren't too keen on patient care and touching the patient etc etc, but now even they are focusing a lot more on patient care and looking at the "whole person" when seeing them.
