Well that sounds like a good thing. Something you should keep in mind, I think physciatry could be one of the highest match rates, this means you could probably go to the caribbean and match physciatry if you want MD. I haven't heard of an unmatched prospective physc, but I'm sure it exists. If you don't care about initials though, DO >> caribbean MD, but your field of interest is one of the MOST realistic of match opportunities from the caribbean, i.e. its not the same as saying I want to match into surgery from the caribbean. On to more your question now, research IS a possibility with DO. I know a chief of neurosurgery, and professor, and this faculty is on most of his latest works with a DO, who I am pretty sure is also a neurosurgeon. DO is your best bet, whos to say you can't do research as a DO? Would there be some bias? Sure there could be some bias, but it will be minimal. I can say if I was going to do physc, I would probably try to go to St. George's (only this one) over DO, but don't take my advice as concrete. As a therapist it might be a bit easier for the patient to see the MD initials, as you are more of a consultant doctor, with some more conversation level with the patient. My meaning, if you are a DO surgeon, its my belief that it is a bit different, as a general surgeon is taking care of things in the body, and the patient is more trying to be eliviated of physcial pain, and may be less inclined to ask about degrees. I feel like if you are conversing with a patient every week, chances are its going to come up, so what's a DO? You are seeing this patient about 10 or maybe 100 times, it would probably come up. Nothing wrong with this, I'm just saying. Again, DO will make your life a lot easier, but you should try to get advice from seasoned people in the field, to find out if being an MD caribbean doc would be difficult in this field, and if you have a good chance of getting the degree. This would take the research question out of play for you, as DO is a more patient centered field, and less concentrated on research in general, this is a fact. But, if you keep working at it, you might get into US MD, and you won't have to have a concern about this.
