after their awards ended rose to over 20% in 2011 from just under 10% in 2007. The trends described here suggest collectively that physicians are declining to pursue research, especially basic science research, in their immediate postgraduate and early faculty phases. However, there does appear to be a solution in our midst. A working group of the Advisory Committee to the NIH Director found that only about 5% of full-time MD faculty at academic U.S. medical centers held NIH funding in 2011 and 2012, whereas over 28% of MD-PhD dual-degree faculty held NIH funding (3). This striking difference emphasizes the value of focusing efforts on dual-degree training programs (or PhD training in the post-MD period) to bolster the physicianscientist workforce. Nevertheless, MD-PhD training programs are not immune to the financial restraints medical schools are facing today. Recently, the Concord Monitor reported that Dartmouth University elected to suspend recruitment into its MD-PhD program pending a reassessment of its “strategic goals of sustainability and excellence” (4). This and similar recent decisions raised fears in the training community that the long-term educational mission of medical schools is falling prey to short-term financial considerations (note that after the outcry from the local academic community, the decision by Dartmouth University has since been partially reversed). Therefore, it is imperative that we as an academic community recommit our efforts to ensuring the training of the next generation of physician-scientists. Several concrete measures can be taken: 1) Increase dual-degree training investment by the NIH. Whereas MD-PhD programs supported by institutional funds have reported success in training students, data consistently show that MSTP-funded programs (likely because of their rigorous accountability, defined programmatic curricula, and full tuition/stipend support) have better retention rates and overall student success, as measured by a variety of outcomes (5, 6). Because most MD-PhD programs recruit students regionally, broadening of the MSTP to regions of the country with less representation (eg, the South, Southwest, and Midwestern regions) will help to extend dual-degree opportunities and enhance diversity in the physician-scientist workforce. 2) Increase dual-degree training investment by medical schools. Data from the Association of American Medical Colleges show that applications to MD-PhD programs nationFigure 1. K award submissions to the National Institutes of Health by year. Data are from the ally have increased about 2% annuNational Institutes of Health Research Portfolio Online Reporting Tools ally (on average) over the last 6 years (http://report.nih.gov/success_rates/index.aspx), accessed March 16, 2014. selves or a result of failure to integrate research training opportunities in those specialties. Protected research time during specialty training (residency and fellowship) proves especially crucial for longterm retention in academics. The NIH K award program is a largely salary-based award program to support an intense research training phase between fellowship and an independent faculty position, a period during which junior researchers build their research credentials to compete for academic jobs. Two K award mechanisms (K08 and K23) are designed exclusively for physician-scientists, with the K08 awarded to investigators performing basic and translational research and the K23 awarded to investigators performing clinical research. As shown in Figure 1, the total number of K08/K23 submissions to the NIH has been steadily declining since 2005, whereas submission of K01 grants (those that go to PhD-only scientists) have shown stabilization or a slight increase in recent years. Perhaps more concerning for the future of basic science research is that the decline in physicianscientist K award submissions is largely accounted for by a decline in the K08 mechanism, a finding that reflects a shift away from basic bench and translational research to more clinically oriented research. This declining trend in K08 submissions is observed at the individual institute level, including the National Institute of Diabetes, Digestive, and Kidney Diseases and the National Heart, Lung, and Blood Institute, through which most endocrine physician-scientists are funded. Indeed, this diminishing group of basic/translational physician-scientists is the very one we count upon to submit original research to Molecular Endocrinology. What remains unanswered is whether the recent academic climate, which emphasizes that compensation be balanced by revenue, has been contributing to the overall K08/K23 grant submission trends. But it is hard to imagine that it has not contributed. According to the National Institute of Diabetes, Digestive, and Kidney Diseases, the number of combined K08 and K23 awardees who turned to private practice just 5 years

(7). Therefore, an interest to pursue the physician-scientist pathway at the predoctoral level remains robust. Investment in dual-degree training by medical schools could take many forms. For example, schools should consider the option of creating new MD-PhD training positions by redeployment of some resources used to support PhD- and MD-only training positions. Establishing programs that offer PhD degrees in the post-MD training period (residency and fellowship) would encourage rigor and structure into research training while additionally diversifying the student body in graduate programs. Additionally, some institutions (such as Washington University in St. Louis and Indiana University) have been successful at leveraging philanthropic support to generate large endowments that support dual-degree MD-PhD training. Clearly, all of these are the types of commitments that will require reevaluation of training priorities at the highest levels of medical school administration. 3) Increase the number and breadth of postgraduate training programs that integrate research and clinical training. Several highly committed institutions have initiated so-called physician-scientist training programs, which provide one-on-one mentorship and protected time for MD trainees to engage in research during residency and fellowship training. Although many of these programs are based in internal medicine residencies/fellowships, in recent years, there has been growth into other specialties (such as the Morris Green Physician Scientist Development Program for pediatricians at Indiana University and the Clinical Neuroscientist Training Program for neurologists at Yale University). Given the changing specialty choices of MD-PhD graduates described earlier, the establishment of physician-scientist training programs in procedure- and imaging-oriented specialties will be especially important. 4) Support the mentors of future physician-scientists. The decline in K08 submissions and the increase in percentage of former K awardees entering private practice are alarming trends. What’s the problem here? A mantra we hear often in academics is mentorship, mentorship, mentorship. Indeed, the best mentors for physician-scientists are physician-scientists themselves. The importance of mentorship was recognized by the NIH, which developed a unique award mechanism called the K24. The K24, a salary-based award, was conceived to allow productive, clinically oriented physician-scientists to have protected time to mentor the next-generation of clinical investigators. Yet no such award exists to support basic science-oriented physician-scientist mentors. Although it is unclear whether the K24 mentorship award has helped mitigate the de-

cline in K23 submissions, it is not far-fetched to assume that it has. Broadening the K24 program to include basic science-oriented physicians could be one step in the right direction, but medical schools also need to invest in these individuals, whether through competitive internal mentorship support programs or through incentives based on training accomplishments. The measures cited above should be considered only a framework for further curricular and funding reprioritizations that need to be initiated by the NIH and medical school administrations. The NIH has recognized the challenges facing physician-scientists and, to this end, has established a Working Group on Physician-Scientist Workforce (8) to provide a comprehensive assessment of the state of the workforce and the impact of current NIH funding policies. But impactful change can happen only when medical schools recognize that there is an emerging problem. Fortunately, many schools have made that recognition, and they should serve not only as examples for everyone else but also as the most vocal advocates for change. Raghavendra G.
