ABSTRACT
BACKGROUND:
Historically, practicing neurosurgeons have been key drivers of neurosurgical innovation. We sought to describe the patents held by U.S. academic neurosurgeons and to explore the relationship between patents and royalties received.METHODS:
The Centers for Medicare and Medicaid CMS Open Payments Data was used to identify academic neurosurgeons who had received royalties and royalty amounts during a 5-year period (2013-2017). Online patent databases were used to gather patent details. Patent citations and 5-year individual and departmental patent Hirsch (h)-indexes were calculated. Royalties were correlated with the number of patents, patent citations, and patent h-index.RESULTS:
We found that 119 academic neurosurgeons (7.8%) from 57 U.S. teaching programs (48.3%) had received royalty payments; 72 (60.5%) had published 648 patents. All surgeons were men, with approximately one half in the "late" stages of their career (45.3%) and subspecializing in spinal surgery (50.4%). The patented products or devices were most commonly used for spinal surgery (72.1%), with 2010-2019 the most productive period (n = 455; 70.2%). The median number of citations per patent was 32 (range, 0-620), with 33% having ≥100 citations. The highest individual and institutional patent h-index was 95; 25 (34.7%) neurosurgeons had a patent h-index of ≥5. The median total royalty payment per individual neurosurgeon was $111,011 (range, $58.05-$76,715,750.34). Royalties were correlated with the number of patents (Spearman r = 0.37; P ≤ 0.001), citations (Spearman r, 0.38; P ≤ 0.001), and inventor h-index (Spearman r = 0.38; P ≤ 0.001).CONCLUSIONS:
Few U.S. academic neurosurgeons (7.8%) receive royalties and hold patents (4.7%), with an even smaller select group having a patent h-index of ≥5 (1.6%).Palavras-chave
