Thanks for the personalized thread, although I think you might have gotten a better response had you named it "DO vs MD EM residencies," but then again I'm sure you'll get a lot of trollers looking to see what sexual question you may have asked...
I originally had planned on going to a DO residency, mainly because I thought it was impossible for a DO to land an MD EM residency, since, to be honest, we can be viewed as the underdog in the application process, and EM is somewhat competitive. I had this idea up until about the end of my second year, when I realized that close to 8% of all MD EM residents are in fact DOs.
That being said, there are about 20 or so DO EM residencies. Some better than others. I can't really comment on which are the best ones... that should be revealed to you upon your interview there. Residency is more of a personal decision, IMHO, than of a "US News Ranking." I liked a smaller program in a big city, so USF/TGH is perfect for me (6 residents a year, 50-70k visits a year, lots of penetrating trauma if that's what you like). Other programs have fewer visits but have varying pathology. Its up to you to decide what you look for in a residency.
As a second year medical student you are a big early in the game. Concentrate on classes, do well on boards, then look around your third year. Do a few EM electives. Hang out in the ER every once in a while.
Now down to the nitty gritty. I would think that the best DO EM program is Albert Einstein Medical Center in Philly, PA. Dually accredited, 4 year program. Excellent training. I rotated there. It wasn't for me but the training there is top-notch, very high acuity. Consistently perform well on their exams. Their fourth year residents are ultra-smart, but they should be since most MD EM residencies are three years...
