OK, let me see if I can address this. Growing up, I was a military brat and was treated, primarily, in military hospitals. As a young child, I didn't notice a difference between the two, but as I got older I did. The MD's tended to stand across the room from you with a clipboard or, God forbid, a TAPE RECORDER, and hardly even look at you as much as whatever they had in their hands. The DO's, on the other hand, would sit or stand right in front of you, and would immediately start using their hands to try and discover what your problem was. They were much more personal and personable. And it all comes down to a difference in training and a difference in approach to your patients. Think about the movie "Patch Adams". What did the dean tell them on the first day? People don't want friends, or someone to share their burden with. They want stone-hearted, coldly professional, physicians.
Well, you'll never hear that uttered in a DO school, but that is exactly what MD's preach. So, the "textbook" training is all the same. In the end, both are equally qualified to practice medicine. But, is is the "Kinder, gentler, approach", if you will, that makes DO's different and in the opinion of our patients and ourselves, better. Then, there is the issue of the more holistic approach, which MD's are slowly absorbing into their own methods, and OMT which DO's still practice exclusively. So, when you look at the individual parts, DO's and MD's aren't all that different; however, many times the whole is greater than the sum of its parts. This is one of those occasions. Put it all together, and DO's ARE completly different from their MD bretheren.
