Context Physician-scientists play a unique and critical role in medical research. Nonetheless, a number of trends followed during the 1980s and 1990s revealed that this career pathway was in serious jeopardy. Physician-scientists were declining in number and were getting older. A variety of factors were thought to contribute to this problem, including increasing indebtedness of medical school graduates caused by rapidly rising medical school tuition costs.

Objective To evaluate the impact of recently initiated programs from the National Institutes of Health (NIH) and several not-for-profit institutions designed to revitalize the physician-scientist career pipeline.

Design We assessed recent trends in the physician-scientist career pipeline using data obtained from the NIH, the American Medical Association, the Association of American Medical Colleges, and other sources.

Main Outcome Measures Total numbers of physicians performing research, grant application numbers and success rates for MDs, MD-PhDs, and PhDs at various stages in their careers, interest in research among medical students, medical school tuitions and postgraduate salaries, numbers and composition of applicants for NIH loan repayment programs, and gender distribution of young physician-scientists.

Results The number of physician-scientists in the United States has been in a steady state for the past decade, but funded physician-scientists are significantly older than they were 2 decades ago. However, the study of early career markers over the past 7 to 10 years has demonstrated increasing interest in research careers by medical students, steady growth of the MD-PhD pool, and a new burst of activity in the “late bloomer” pool of MDs (individuals who choose research careers in medical school or in residency training), fueled by loan repayment programs that were created by the NIH in 2002. Several recent trends for more established physician-scientists have also suggested improvement.

Conclusions Although it is too early to assess the impact of these indicators on the long-term career pathway, the recent growth in activity in the physician-scientist career pipeline is an encouraging development. Continued funding of these new programs, coupled with sustained support for physician-scientists committed to the pathway, will be required to maintain these positive trends.

The percentage of total research project grant awards awarded to investigators older than 50 years is shown for each degree type. For this and all other figures, MDs include individuals with an MD degree alone plus all individuals with an MD plus another professional degree other than PhD. Similarly, MD-PhDs include all individuals with these 2 degrees plus any other professional degrees. Source: National Institutes of Health (NIH).

A, Applications by degree and year. Definitions of MDs, MD-PhDs, and PhDs were described in the legend for Figure 2. All data were obtained by summing information from all of the LRPs except for contraception and infertility, which was established before 2002 and which is very small compared with the new programs. New applications refer to applicants who had not previously applied for an LRP. B, New (first-time) applications by degree and gender. Small numbers of applicants did not specify gender, accounting for the small difference between the total number of new applicants shown in panel A and the data shown here.
