Just figured I'd throw my .02 in too. By guaranteed ins, this means a program director says to you, "hey, we love you and love to have you here. Do you want to sign this contract???" This is pretty typical, from what I hear, of Osteo residencies. Now why you want to stay away from some of the osteo programs... Well many reasons, but I'll just give you mine:
1. location: (as you mentioned)
2. volume: I know of some osteo training programs that see only around 25K per year. I need more practice.
3. Trauma Centers: Most are not. The trauma centers are usually the larger allo program in the same town. I like trauma and I think that its fun. I don't want it going somewhere else.
4. Strength of off service rotations: Sometimes hospitals will correct this--by sending you out of state for a month or 2 to a larger hospital. I don't want to leave my state. Its warm here.
5. Feel: I want to work in a big county hospital that sees lots of patients w/ diverse pathology. Quite a few of the osteo programs are at smaller, community hospitals with limited pathology.
6. Academics: Do you want to do some research? I'm not sure if I want to, but I want to know that there is strong mentorship and lots of opp's should I want to.
I want to make this perfectly clear. I am refering to SOME osteo programs. Please don't think that I'm saying don't apply to DO progs. There are also some good Osteo programs out there so shop around for yourself. Just be careful and objective. One more thing: DO programs, for the most part, are MUCH more easier to get into than allo. You will match as long as you are not an anaerobe.
Good luck,
