Background
Obtaining National Institutes of Health (NIH) funding over the last 10 years has become increasingly difficult due to a decrease in the number of research grants funded and an increase in the number of NIH applications.
Study Design
NIH funding amounts and success rates were compared for all disciplines using data from NIH, FASEB, and Blue Ridge Medical Institute. Next, all NIH grants (2006–16) with surgeons as principal investigators were identified using NIH RePORTER and a grant impact score was calculated for each grant based on the publications’ impact factor per funding amount. Linear regression and one-way ANOVA were used for analysis.
Results
The number of NIH grant applications has increased by 18.7% (p=0.0009), while the number of funded grants (p < 0.0001) and R01s (p < 0.0001) across the NIH has decreased by 6.7% and 17.0%, respectively. The mean success rate of funded grants with surgeons as principal investigators (16.4%) has been significantly lower than the mean NIH funding rate (19.2%) (p = 0.011). Despite receiving only 831 R01’s during this time period, surgeon scientists were highly productive with an average grant impact score of 4.9 per $100,000, which increased over the last 10 years (0.15 ± 0.05 /year, p=0.02). Additionally, the rate of conversion of surgeon scientist mentored K awards to R01’s from 2007–12 was 46%.
Conclusions
Despite the declining funding over the last 10 years, surgeon scientists have demonstrated increasing productivity measured by impactful publications and higher success rates in converting early investigator awards to R01s.
