Anesthesiology is one of 21 medical specialties in the United States that is currently experiencing a physician shortage or expected to have one in the near future. The causes of physician workforce shortages are multifactorial and include the aging physician population, burdensome debt from medical school, a static production of new physicians, and reduced physician work hours, among others. Expectations for work–life balance, hours spent at work, a culture involving high stress, and burnout are other key contributors to physician shortages.

“It’s important to increase our understanding of the issues contributing to the physician shortage in anesthesiology,” says Fredrick K. Orkin, MD, MBA, SM. “By identifying practice patterns and retirement plans of older anesthesiologists, we can use this information to guide how we manage consequences resulting from the undersupply of these specialists. These data could also be used by physicians and their employers to prepare for shortages in the future.”

Analyzing Trends in Retirement

A study published in Anesthesiology by Dr. Orkin and colleagues surveyed thousands of anesthesiologists and other specialists aged 50 and older to determine trends in work activities, professional satisfaction, health and financial status, and retirement plans and perspectives. The goals included identifying the major factors influencing decisions to continue practicing or to retire and evaluating the impact of retirement decision making on the size of the current and future workforce.


Several important findings emerged from the study by Dr. Orkin and colleagues. First, older physicians logged significantly more hours of work during the week than other professionals. On average, older anesthesiologists and other older physicians worked about the same number of hours per week (49.4), but this average topped that of attorneys (44.9), engineers (43.0), and registered nurses (37.3). Although the length of the older anesthesiologists’ workweek was similar to that of other older physicians, anesthesiologists spent more of their time (81%) in clinical care, especially those specializing in critical care medicine or pain management.

“It’s important to increase our understanding of the issues contributing to the physician shortage in anesthesiology.”

Anesthesiologists also participated in clinical care well into their 60s. As anesthesiologists aged, time spent in clinical care decreased and more began working on a part-time basis, particularly women. One-sixth of respondents reported working in a self-defined part-time mode. “Since part-time status is more prevalent among women and more women are entering anesthesiology, this work model is likely to be even more common in the future,” says Dr. Orkin.

Reasons for Retirement Among Anesthesiologists

When compared with other older physicians, several factors were cited as “very important” in retirement planning by older anesthesiologists. More than half reported that their decision to retire from patient care was based on on-call responsibilities. More than one-third cited insufficient reimbursement, lack of professional satisfaction, increasing regulation of medicine, and decreasing clinical autonomy. Conversely, more than two-thirds of older anesthesiologists reported that career satisfaction was the driving force behind deciding to remain clinically active.

Poor health was cited by 64% of anesthesiologists retiring in their 50s, compared with a 43% rate observed among those retiring later, according to the study (Figure 1). On the other hand, subspecialists in pain management and critical care who left their practice cited loss of clinical autonomy as a major influence. In forecasting models, 30% of anesthesiologists were predicted to work past the age of 65; about 18% will work past age 70, and 10% will work at age 80 (Figure 2). Based on these results, Dr. Orkin says “interventions to retain physicians in the workforce may need to be age-specific or subspecialist-specific.”

Important Implications for Retaining Physicians

The study by Dr. Orkin and colleagues further supports the notion that greater attention should be focused on potentially modifiable factors to alleviate the anesthesiologist workforce shortage. “Several initiatives have already been launched throughout the U.S., including workplace wellness programs in anesthesiology. Other interventions have been initiated to enhance professional satisfaction so that the incidence of premature retirement decreases. Unfortunately, more of these efforts are needed due to the fact that aging will inevitably play a role, affecting everything from muscle to mind.”

Dr. Orkin urges thinking outside the box as new initiatives are developed. “There is an under-recognized trend toward part-time work,” he says. “Despite the potential role of this employment model to decrease the aggregate clinical workforce, part-time work also offers the possibility of retaining older anesthesiologists with needed skills in the clinical setting for longer periods.”
