Bibliometrics assessing academic productivity play a significant role in neurosurgeon career advancement. This study aimed to evaluate the influence of multiple author profiles on SCOPUS® on neurosurgeon author-level metrics (h-index, document number, citation number).A list of 1671 academic neurosurgeons was compiled through public searches of hospital and faculty websites for the 115 neurosurgical residency training programs. H-index, document number, and citation number for each neurosurgeon were collected using the SCOPUS® algorithm. For surgeons with multiple profiles, total document number and citation number were calculated by summing the results of each profile. Cumulative h-indices were calculated manually. Comparisons were made between surgeons with a single SCOPUS® profile and those with multiple profiles.124 neurosurgeons with multiple profiles were identified. Gender distribution (p=0.47), years in practice (p=0.06), subspecialty (p=0.32), and academic rank (p=0.16) between neurosurgeons with single profiles vs. multiple profiles were similar. The primary profile h-index median was 16 (8-34), combined profiles median was 20 (11-36), and percent loss median was 17.3% (3%-33%) (p0.001). For document number, the primary profile median was 46 (16-127), combined profiles median was 55 (22-148), and percent loss median was 16.2% (7%-36%) (p0.001). For citation number, the primary profile median was 1030 (333-4082), combined profiles median was 1319 (546-4439), and percent loss median was 14.1% (4%-32%) (p0.001).Academic neurosurgeons in the United States with multiple existing profiles on SCOPUS® experience a 17.3%-loss in h-index, a 16.2%-loss in document number, and a 14.1%-loss in citations, heavily undercounting their perceived academic productivity. |
