Physician’s Assistants (PAs) and Advanced Registered Nurse (ARNPs) are helping lower costs and increase access. While some nurse practitioners, can operate relatively independently; other nurse practitioners and most physicians’ assistants, cannot. Why?
Physicians are adamant that they maintain a high degree of control over these and other healthcare workers. This is a throwback to the nineteenth century—which is kind of interesting in a weird sort of way. The story, and I cannot vouch for its accuracy, although all my research seems to support it, is that the country was besotted with traveling medicine shows hawking patent medicines (You’ve seen it in the movies—“One for a man, two for a horse”). The physician industry supposedly promised to get things under control if they were put in charge of medical practitioners, i.e., physicians and surgeons (MD). It, at best, minimized, if not blackballed, osteopathic physicians (DO), chiropractors (DC) and chiropodists, now known as podiatrists (DPM).
A physician, at the time, could authorize any hireling under his license to perform any duty under the concept that the doctor was “the captain of the ship” and was responsible for everything. Therefore, he had authority to authorize any employee to do anything—hopefully, but not necessarily, after some training.
Today, many non-physician healthcare workers are licensed in their own right; in most states this includes nurses (of all levels), therapists (of all varieties), and technologists (ditto). These people are trained and possess technical skills that physicians do not. Generally speaking, only television doctors leave their practice in order to operating high technology devices. It’s good theater but bad economics.
Many of the other healthcare careers such as nurse practitioners, physicians’ assistants, etc., have made significant advances Unfortunately, old attitudes die hard, and there are too many physicians who try to maintain an inordinate control over everything, including these other professionals. Nurse anesthetists and physicians’ assistance must be “supervised” by a physician, although such supervision does not require actual observation or even the presence of the supervising physician.
Efforts to keep others under control have led to some bizarre arrangements. In radiology, for example I’m told that the technologists are now required to periodically retake the examination that initially proved their competence even though there has been continuing education requirements for 40 years. If true, I believe this is a unique requirement, but a warning to all others. Of all the physicians’ assistants, only those specializing in radiology are not permitted to interpret x-ray or other diagnostic images.
Some blame the American Medical Association, a very powerful organization with effective lobbyists. However, it apparently speaks for a self-selected group of physicians. Out of 923,308 practicing physicians, the most recent numbers available indicates that only 228,000 belonged to the AMA. If you don’t round, that’s just less than 25 percent.
Nobel Laureate Milton Friedman and his wife, who wrote the book Free to Choose, asserted that the AMA functions more like a guild with the goal of increasing physicians’ wages and fees by limiting both the supply of physicians and the competition from non-physician groups.
This is yet another issue that must be addressed if we are truly interested in fixing healthcare.
