I really love the DO philosophy and will apply DO. If I apply to both DO and MD and am accepted to both, I'm not sure what I would choose.
Because of the nature that this thread has taken, let me try to give you my perspective, which I believe is what you have been asking for - perspective.
I have worked with multiple DO's, ranging from an osteopathic clinic (centered around manipulation) to surgeons at my local hospital. I have also applied to both MD and DO schools this year. So, I am framing my comments to let you know where I'm coming from.
I received a DO acceptance just a short time ago, and have faced a spectrum of reactions. Some have asked me what a DO actually is, and I've had to explain to the best of my ability. Others have been excited because their primary care physicians are DO's, and they love them. So it is partially a question of exposure - the more people know about DO's, the more comfortable they are with them, and I am finding more and more people satisfied with their DO's.
As far as my hospital is concerned, we have a number of DO's in different departments - the staff and patients don't seem to notice the distinction at all. They are just as well respected, but this is with the caveat that most are unaware that they
are DO's.
If more people were to become educated about Osteopathy and its philosophies, and were exposed to quality DO's, the recognition and prestige factor would skyrocket. These factors may be important to you, especially if they're important to your patients. The scope of practice, however, is limited only by how you choose to limit it.
So to conclude, does a stigma still exist? Yes. Is it getting better? Yes, especially with greater exposure. If I may use a (really bad) analogy, remember when hybrid cars hit the market? Only a very small percentage of the population wanted them because they were so "different" in design. Someone had a stroke of genius and realized that if the hybrid vehicles looked like regular cars, then people would forget about the differences and start to realize the benefits...hence the upturn in hybrid car sales. If people, then, were to begin to realize the similarities between MD's and DO's rather than the differences, then they, too, can make informed decisions about their care, and focus on what makes an individual a good a doctor.
