The work RVU is the current medium of exchange in clinical practice for all physicians, both private and academic. And as the numbers of physicians employed by academic medical centers...
At this month’s American Thoracic Society meeting, it was reported that 1/3 of practicing pediatric pulmonologists in the United States are over age 60, a scary number since that indicates we are soon facing shortages of pediatric pulmonologists. It turns out that it is not the only specialty with disproportionately older physicians and these statistics have implications for our future physician workforce. In the U.S., air traffic controllers have a mandatory retirement age of 56 years-old, national park rangers are 57, military officers are 64, and pilots have a mandatory retirement age of 65. In the Roman Catholic Church, priests have a mandatory retirement age of 70. There is no mandatory retirement age for physicians and consequently, some specialties have become very top-heavy with older doctors.
The Association of American Medical Colleges tracks physicians in different specialties by the percent who are under age 55 versus those who are over 55 and the data is summarized in the graph below:
For all physicians combined, 56.8% are under age 55 and 43.2% are over age 55. However, some specialties are disproportionately older or younger. My own specialties of pulmonary (15% under age 55) and critical care (84.3% under age 55) is probably more a reflection that most of these physicians are dual certified and tend to do more critical care earlier in their career and migrate to more pulmonary later in their career. Similarly, emergency medicine with 65.4% under age 55 is a relatively new discipline that did not become recognized as a specialty until 1979 and did not offer a board examination until 1980. There are some specialties that are more concerning. For example, pathologists, psychiatrists, cardiologists, and thoracic surgeons tend to be older whereas interventional radiologists, nephrologists, and pediatricians tend to be younger. Those specialties that have more than 50% of the physicians over age 55 are likely to be in high demand in the next 10 years as these older physicians retire.
A study in the Journal of Medical Regulation from 2017 analyzed the U.S. physician workforce by a number of parameters, including age. Taking all physicians together, 29.3% of practicing physicians are over the age of 60. The reasons why there are so many older physicians in the workforce are complex and include (1) a later age of entry into the workforce due to lengthy training requirements, (2) a high amount of debt from the cost of education, and (3) less physical demands than many other professions.
The median age of retirement from clinical activities by physicians is age 65 years as shown in this graph from a study published in the Annals of Family Medicine. The retirement age varies by specialty, for example, the median age of retirement from clinical activities is about 64.5 years for OB-GYNs and 66.5 years for cardiologists. Women tend to retire 1 year earlier than men. Because many physicians continue to be active in other professional activities after retirement from clinical activities (such as administration or education), the median age of retirement from any professional activity tends to be about 1 year later than the retirement from clinical activity. Therefore, the median age of retirement from any professional activity is at age 66 years when examining all physicians. But remember that these data are for the median age of retirement and that means that half of all physicians retire from clinical activity after age 65 years.
As a medical director, one of the most uncomfortable tasks I have to do is to tell an older physician with a long history of dedication to the medical profession and the community that it is time that he or she needs to stop seeing patients. It is not because of age per se but because of quality concerns. It turns out that this is a valid issue. A study in the BMJ found that for Medicare patients, the 30-day survival after hospital discharge depends on the age of the physician. 30-year old physicians had a 10.5% 30-day patient mortality rate whereas 70-year old physicians had a 13.5% 30-day patient mortality rate. Although part of these results could be because older physicians tend to have combined inpatient and outpatient practices with an older (and sicker) panel of patients whereas younger physicians tend to be hospitalists that care for a wider age range of Medicare patients, it is also quite possible that older physicians do not practice as high of quality of medical care as younger physicians. This has unfortunately been my experience with some older physicians.
There can be a lot of reasons why physicians retire and last year I wrote a blog post about “When Physicians Reach Their Use-By Date” to reminisce about how some of the more memorable physicians I have known retired. The keys are to have enough self-awareness to know when your clinical skills are lagging behind your peers and to be willing to pick up on subtle hints from those peers that you are not the clinician that you used to be.
So, what does all of this mean? First, doctors retire later than people in many other professions. Second, doctors who chose to work beyond age 65 need to be attentive to their quality of practice. Third, and perhaps most important from a national health care standpoint, certain specialties are dominated by older physicians who will be retiring soon, thus creating demands for those specialties that will be difficult to meet.
The hockey legend, Wayne Gretzky, famously said: “Skate to where the puck is going, not to where it has been”. I think that this has implications for our medical students who are selecting specialties – knowing what specialties are going to be in demand rather than what are currently in demand should affect their career choices.
