After reading the history about DO's I found it really interesting to note that most foreign med students from Europe and Asia are not officially entitled MD, they are given MB, MS, etc. When they come to the US they are allowed to adapt the MD label after they pass foreign student boards. In the late 70's some DO's in put a case in front of their state's supreme court that said either force these graduates to go by their label or allow us to use MD as well since we have the same training. This case was of course against the wishes of the AOA, but the state allowed them to put the MD label on their cards and jackets. Similar cases were spread around the country with a majority of them being thrown out. I agree with everyone in this thread that you will not experience any job unprofessionalism. I am going to a DO school next year and am very proud of it. My mother was upset at first until we attended an open house at CCOM and she realized that I want to be a part of something that could give me more tools to treat patients. As far as my personal experience as an EMT in St. Louis I find that more and more BIG ALLOPATHIC HOSPITALS (Barnes, Slu, St. John's) Trauma 1 ERs, have many DO's in the ER. When I am running "basic" transports I have to get a doctors signature on one of the transport forms and Medicare requires that the doctor DO or MD put their title. One day the form didnt have a title so I asked the ER nurse, what is the doctor's title? She said in a very rude, yet what I found to be humorous response... "What the hell does it matter? He's a doctor!" ... of course for documentation I went to the doctor as asked him nicely... he was a DO.
