CHICAGO — Results of a retrospective review of NIH funding underscore the importance of continued selection and mentorship of neurosurgeons capable of impacting patient care through research, according to a presenter here at the American Association of Neurological Surgeons Annual Scientific Meeting.

In the retrospective review of NIH-funded members of the American Association of Neurological Surgeons (AANS), Arman Jahangiri and colleagues defined the variables associated with neurosurgical NIH funding, the prevalence of funded topics by neurosurgical subspecialty and the temporal trends in NIH neurosurgical funding. The paper won the Journal of Neuro-Oncology Award.

Jahangiri and colleagues followed 6,515 neurosurgeons from 1991 to 2015, including 6,124 MDs and 406 MD-PhDs. The NIH grants were awarded to 391 neurosurgeons. The average total funded years per neurosurgeon was 12.5 years. According to a press release from the AANS, investigators found a higher percentage of MD-PhDs were funded than MDs. The most common grants were R01 (n=128), K08 (n=69), F32 (n=60), M01 (n=50) and R21 (n=39).

For training grants, the release noted 30% of F32 recipients transitioned to K08s (18%) and/or R01s (18%), and 38% of K08 recipients transitioned to R01s. Of the NIH-funded neurosurgeons, investigators discovered 32 (8%) transitioned to funded clinical trials. Funded neurosurgical subspecialties included neuro-oncology (33%), functional/epilepsy (32%), cerebrovascular (17%), trauma (10%) and spine (6%).  

The decrease in K08 funding and the plateau in F32 funding suggests the upward trend in R01s awarded to neurosurgeons during the last 24 years will be difficult to maintain, according to the release.
