Nurse practitioners operating independently of actual M.D.s?  Well, it is likely that such nurse practitioners and physician assistants are in effect doing that now, even though operating in the context of a medical practice.  My worry certainly is the oversight and the liability concerns.  If I go to a nurse practitioner's office and as a result I am injured, is that medical malpractice, or just general malpractice?  It's an important distinction, as it is much more difficult and expensive to sue a doctor for medical malpractice than, say, a motorist for an automobile accident.
