Abstract
INTRODUCTION
Formal training for physician-scientists is needed more than ever in the field of neurosurgery for the good of the patients and the field. National Institutes of Health (NIH) funding is considered as the most prestigious yet competitive research funding to obtain. This study was performed to determine whether a correlation exists between bibliometrics and NIH funding data among academic neurosurgeons and compare the trends in neurosurgery NIH funding to practicing neurosurgeons and non-neurosurgeons between 1993 to 2017.
METHODS
Grants to neurosurgery were extracted from the NIH Reporter. Neurosurgery data from 1993 to 2017 were collected; the following parameters were obtained: primary investigators (PIs), grant type, and total funding. Regression models compared NIH funding over time.
RESULTS
After adjusting for inflation (base year 1993), while funding to both practicing neurosurgeons (P < .00001, R2 = 0.70) and non-neurosurgeons (P < .00001, R2 = 0.61) has been increasing, the percentage of neurosurgery NIH funding going to neurosurgeons (P < .1, R2 = 0.12) is steadily decreasing. Additionally, a total of 542 men were awarded NIH neurosurgery grants compared to 174 women (P < .000001), and the men had a significantly higher average funding per scientist (P < .01). Of the grants awarded to neurosurgery, 30% (213/716) of the awardees were neurosurgeons, and 29% (424/1464) of the awarded grants went to neurosurgeons. There was a rise in active R01 grants 56.4% (207/367) among total active awarded neurosurgery grants, in comparison to the historically awarded R01 rate of 38.2%.
CONCLUSION
The low percentage of new neurosurgeons awarded NIH grants coupled with the lack of formalized training in residency has the potential to worsen the future pipeline for neurosurgeon-scientists. Future residency programs need to incorporate formalized research training and incentives into training despite escalating economic pressures on departments to see more and more patients.
