It is now widely accepted that the United States is on the cusp of deepening shortages of physicians.1,2 This article will briefly review how these shortages could have been anticipated, how they are being manifested, and how policy-makers were drawn to the contrary conclusion, and it will discuss the challenges that now exist as the nation undertakes to expand undergraduate and graduate medical education in an attempt to meet the projected future demand. SETTING THE STAGE FOR FUTURE SHORTAGES Anticipating the Demand for Physicians As physicians, it is natural to think about the future demand for physicians in terms of needs, such as the aging population and the obesity epidemic, or new technologies, such as implantable defibrillators and targeted therapeutics. During the 1990s, many thought that payment systems would drive the need for more primary care physicians. But none of these has proven to be decisive. Rather, the dominant factor that my colleagues and I have observed is growth in the economy overall, because ultimately it is the capacity of a society to purchase health care that determines how many services will be used.3 From 1929 to 2000, the growth in physician supply followed the trend of economic growth rather closely, except in the period after World War II, when the economy grew briskly but the production of physicians lagged behind. In response, medical school capacity doubled, and so did the capacity of residency programs (Fig. 1). By 1980, physician supply had increased to the level that could be predicted from per capita gross domestic product, and it roughly paralleled gross domestic product growth over the next 2 decades. Figure 2 displays this trend and extrapolates the demand for physicians to the year 2025.FIGURE 1.: Medical graduates and PGY-1 residents without previous residency. 1950–2005.FIGURE 2.: Physician supply and demand projections. Extrapolated to 2025.Downward Pressure on Supply—Medical Schools As the supply of physicians began to build in the 1970s, and as health care spending increased, policy-makers feared that too much spending on health care would harm the economy, and many reasoned that it was physicians who drove spending. Therefore, freezing their numbers would be beneficial. Others were alarmed by the fact that, in per capita terms, the growth in physician supply was entirely due to additional specialists, while primary care held constant, thereby tipping the ratio, a process that must be rectified. These 2 philosophies found quantitative support in a series of workforce projections that, in retrospect, were badly designed but that gave strength to the idea that the nation would soon have too many physicians and the medical education pipeline must shut down. Federal support for medical schools abruptly ceased in 1976, and the expansion of both allopathic (MD) and osteopathic (DO) schools ground to a halt (Fig. 1). While DO schools began to grow soon thereafter, MD schools remained at 1980 levels for more than 2 decades. In per capita terms, the output of medical students declined. Downward Pressure on Supply—Graduate Medical Education Graduate medical education (GME) followed a different course (Fig. 1). After growing in parallel with medical school enrollment in the 1960s and 1970s, it paused briefly in the 1980s but then continued its upward path in the 1990s. However, this latter period was not associated with additional US medical graduates but with more international medical graduates (IMGs), some of whom were US citizens but most of whom were foreign nationals. Indeed, by the late 1990s, IMGs accounted for approximately 25% of first year (PGY-1) residents. Looking back over the 35 years from 1960 through the mid-1990s, one can discern an overall upward trend of 350 to 400 additional PGY-1 positions annually. This trend did not escape the notice of planners, most of whom held to the notion that there were too many specialists being trained, and in 1996 a “Consensus Statement” was developed by a coalition of the American Medical Association (AMA), Association of American Medical colleges (AAMC), Association of Academic Health Centers (AAHC), American Osteopathic Association (AOA), American Association of Colleges of Osteopathic Medicine (AACOM), and National Medical Association (NMA).4 It proposed to “reduce the number of GME positions funded by the federal government to a number closer to that of the graduates of US allopathic medical schools,” a proposal that found expression in the Balanced Budget Act of 1997, which froze federal funding for GME at its 1996 levels. This single action fully accounts for the leveling off of physician supply in 2005 and the projected decline thereafter. Indeed, had a cap not been placed on GME, the physician shortages that are developing today would not exist (Fig. 2). Downward Trend of Physician Work Effort A second factor affecting physician supply has to do with the decreasing work effort of physicians. One reason for this relates to aging of the workforce, as the youthful cohorts of the 1970s and 1980s mature. Another is the increased participation of women, and a third is generational—the desire of younger physicians of both genders for more family time, less time on-call and fewer hours overall. Added to this is the 80-hour rule for residents. Finally, increasing numbers of physicians are finding opportunities in health care organizations, pharmaceutical companies and other venues outside of clinical practice. It is the combination of increasing demand for physicians and a decline in their actual and effective supply that is leading to a projected short-fall of more than 200,000 physicians by 2025 (Fig. 2). Evidence of Shortages Although the nation is headed toward very large shortages in the future, evidence of physician shortages exists already. One example is longer waiting times for patients, even when referred by another physician. Hospitals and group practices report increasing difficulty in recruiting physicians, not only in specialties such as urology, radiology, cardiology, gastroenterology, and oncology, which have been experiencing shortages for a number of years, but also in primary care, which is now the most frequent specialty sought by search firms. Young physicians are receiving more jobs offers, higher starting salaries, and larger signing bonuses, particularly in procedural specialties. Some group practices have found recruitment of new physicians too time consuming and expensive and have simply decided to get smaller. Night and weekend coverage is difficult to assure in many areas of the country, and hospitals find that they must compensate specialists for being available to cover emergency rooms. The quest for physicians now provides employment for 8000 recruiters. Surveys of medical school deans confirm the tight physician labor market.5 Similarly, in a recent survey of hospital CEOs conducted by the Council on Physician and Nurse Supply, 45% of respondents reported that recruiting physicians is very challenging and 51% that it is more challenging that 1 year ago. Medical societies and hospital associations in 15 states, which represent more than half of the US population, have issued reports that project shortages of physicians, and 15 specialty organizations have published reports projecting national shortages in their disciplines. Most organizations that had participated in the “Consensus Statement” concerning physician surpluses a decade ago have issued statements that the nation is facing physician shortages, instead. Even the Council on Graduate Medical Education (COGME), which promulgated the notion of physician surpluses throughout the 1990s, has recanted and, based on the approach to planning that my colleagues and I described,3 has projected large shortages of physicians in the coming years.2 CHALLENGE #1: EXPANDING GRADUATE MEDICAL EDUCATION What is needed to fill the gap? Indeed, can it be filled? With the to in the United States is through residency programs by the Council on Graduate Medical Education or the approximately residents PGY-1 positions for the first time this physicians will be in the period from to as is approximately 200,000 too the number of PGY-1 positions had continued to grow after at about more than had been the the previous and such growth were to the number of PGY-1 positions would in more than in and a of new physicians would be over the years from to which is the number of physicians that projected will be (Fig. 1). had the natural of GME been to the United States would not now be facing a physician (Fig. 2).
