IntroductionThe National Institutes of Health (NIH) is the world's largest funding source for research, and the R01 grant is seen as a stepping stone to future granting opportunities for the physician-scientist. Recently, both a gender and degree disparity in scholarly activity has been highlighted in the medical literature.  Objective: To assess NIH R01 funding trends in general surgery over the last decade.MethodsA retrospective review of general surgery funding was extracted from the NIH's Research Portfolio Online Reporting Tools Expenditures and Results database from 2008 through 2017. All principal investigators (PIs) were categorized by gender and academic degree(s). Linear regression analysis assessed NIH grant funding trends over time and comparisons of groups were completed with the t-test.ResultsFrom 2008 to 2017, the NIH awarded 600 R01 grants and $272,669,397 to PIs in general surgery. The majority of R01 grants were awarded to males (76.33%; p < 0.01) and those holding a Doctorate of Medicine (MD) degree (58.33%; p < 0.01). No Doctorate of Osteopathic Medicine (DO) had received an NIH R01 grant during the time studied. No statistically significant trend could be established for the number of R01 grants awarded over time (p = 0.33), grants awarded to males or females over time (p = 0.73 and p = 0.18), or for those holding an MD or other type of degree over time (p = 0.30 and p = 0.39). Also, no statistically significant trend was established for increased grant funding over time (P = 0.88) but females and those holding an other type of degree (Doctorate in Philosophy (PhD), Doctorate in Science (DSc), Master of Public Health (MPH), etc.) experienced an increase in the total dollar amount of funding over the time studied (p < 0.01 and p < 0.01).  Conclusion: For the years studied, a gender and degree disparity exists for those receiving an NIH R01 grant in general surgery. However, an increase in total grant funding has been seen for both females and non-physician scientists over from 2008 through 2017.
