National Institutes of Health Funding for Surgeon-Scientists in the US—An Update and an Expanded Landscape

Abstract

ImportanceCurrent reports suggest that the surgeon-scientist phenotype is significantly threatened. However, a significant increase in the proportion of surgeons in the workforce funded by the National Institutes of Health (NIH) from 2010 (0.5%) to 2020 (0.7%) was recently reported and showed that surgeons primarily performed basic science research (78% in 2010; 73% in 2020) rather than clinical research.ObjectiveTo provide an update on the status of surgeons funded by the NIH for fiscal year (FY) 2022.Evidence ReviewNIH-funded surgeons were identified in FY2012 and FY2022, including those who were awarded grants with more than 1 principal investigator (PI) by querying the internal database at the NIH. The main outcome for this study was the total number of NIH-funded surgeons in FY2012 and FY2022, including total grant costs and number of grants. The secondary analysis included self-reported demographic characteristics of the surgeons in FY2022. The research type (basic science vs clinical) of R01 grants was also examined.FindingsIncluding multiple PI grants, 1324 surgeon-scientists were awarded $1.3 billion in FY2022. Women surgeons increased to 31.3% (339 of 1084) of the population of surgeon PIs in FY2022 compared with 21.0% (184 of 876) in FY2012. Among surgeon PIs awarded grants, a total of 200 (22.8%) were Asian, 35 (4.0%) were Black or African American, 18 (2.1%) were another race (including American Indian or Alaska Native, Native Hawaiian or Other Pacific Islander, and more than 1 race), and 623 (71.1%) were White. A total of 513 of 689 R01 grants (74.5%) were for basic science, 131 (19.0%) were for clinical trials, and 45 (6.5%) were for outcomes research.Conclusions and RelevanceNIH-funded surgeons are increasing in number and grant costs, including the proportion of women surgeon PIs, and are representative of the diversity among US academic surgical faculty. The results of this study suggest that despite the many obstacles surgeon-scientists face, their research portfolio continues to grow, they perform a myriad of mostly basic scientific research as both independent PIs and on multidisciplinary teams.
