IAAMD, and core faculty for an Internal Medicine training program.
About 20% of my colleagues and about 40% of the residents at any one time are DOs.
There is a subtle difference in approach. I wouldn’t call it a unique philosophy, and “whole patient” has been bandied about so much as to lose much of its meaning.
But Neurodoc’s observations that there are fewer DO neurosurgeons, ophthalmologists, dermatologists, etc. echoes what I said earlier, and is due to the slight difference in emphasis in a DOs training compared with an MDs training. From day 1, DOs are being trained to become primary care doctors, not consultants who see a patient one or two times for one specific issue, and defer other matters to the primary care physician or provide recommendations for the referring physician to implement. To the degree that this represents a “whole patient” approach, it is largely true of DOs, but is equally true of MDs in primary care specialties. Some of the DO residents who graduate from our program do go into subspecialty training, but even so, they tend to gravitate towrds those where one is likely to become the primary care doc for a significant proportion of their patients - Oncology (cancer patients) and Nephrology (dialysis/transplant patients) and Infectious Disease (HIV-infected patients), for example, rather than Allergy or Gastroenterology. Some do decide they do not like primary care medicine, and shrug off the DO concept and go into more narrowly focused areas of medicine.
OMT, Osteopathic Maniulation Therapy, is considered mainstream for pretty much any kind of musculoskeletal disorder or chronic pain syndrome. A few DOs use it for treating a number of other conditions, however, such as asthma, peptic ulcer disease, or palpitations. This is not well accepted by MDs or most DOs, either.
