I'm in a DO residency now and the graduates form our system haven't had any difficulties obtaining good jobs in good locations (last 2 are now in LA and Vegas). After speaking with a lot of attendings they have informed me that the DO residencies do a terrific job of teaching how to be a proficient provider since our case load is high (our facility each resident does about 1200 cases a year). In general we train at smaller community hospitals where turnover is key so we learn to be fast and efficient to allow the day to continue at a solid pace. We're able to run our rooms without needing to set up multiple drips and lines (unless the case deems that necessary). From what I've heard from highering practices, they like DO residents because they can handle thier own and they don't slow anybody down with turnover. That being said, we don't get a lot of the fancier more dramatic cases that you'll see at a large university facility, but then again, you'll have to work a facility like that post-grad to see those cases again. I'd say if you want to do anesthesia at a facility other than at a level 1-2 trauma center DO is just fine. If you want to do transplants and larger more risky, rare procedures than MD is the way to go. Personal story, my bro is a DO trained at Case Western. His group just highered an MD from Mayo who struggles with lap chole cases. Why,she didn't see a lot of that in residency. Give her a liver transplant and she kills it. Things to consider. Either way DOs have boards too and its not like those count for nothing. Board certified is board certified.
