Scholarly Activities and Indices Among Academic Endovascular Specialists: A Comparative Analysis Between Interventional Radiologists and Vascular Surgeons

Purpose: To report scholarly metrics amongst academic endovascular specialists. Material and Methods: Faculty pages identified interventional radiologists and vascular surgeons at academic institutions. Members were classified as assistant, associate, or full professors. Scopus was used to extract publication and citation records. Data extracted included: number of publications, number of citations, h-index, i-10 index, hc-index, m-quotient, e-index, and g-index. Results: Two hundred seventy six interventional radiologists and 266 vascular surgeons were included. Mean publications for interventional radiology assistant, associate, and full professors were 17.81, 48.77, and 131.65 and the citation counts were 311.45, 1051.08, and 3981.71, respectively. Mean publications for vascular surgeon assistant, associate, and full professors were 24.00, 48.7, and 161.37 and the citation counts were 414.33, 1147.89, and 5747.00, respectively. Multivariable proportional odds model for interventional radiologists showed a positive correlation between the academic rank and publication count (c = 0.028), h-index (c = 0.090), i10-index (c = 0.014), hc-index (c = 0.052), e-index (c = 0.016), and g-index (0.037). There was a negative correlation between m-quotient (c = -1.745) and citations (c = -0.001) and academic rank. Multivariable proportional odds model for vascular surgeons showed a positive correlation between the academic rank and publication count (c = 0.037) and g-index (c = 0.083). There was a negative correlation between m-quotient (c = -2.232) and hc-index (c = -0.065) and academic rank. Conclusion: Citation count and h-index are positively correlated while m-quotient is negatively correlated with academic performance for endovascular specialists. (C) 2019 Elsevier Inc.
