Men Receive Three Times More Industry Payments than Women Academic Orthopaedic Surgeons, Even After Controlling for Confounding Variables. Issue 7 (July 2020) - Forrester, Lynn Ann
Abstract: Background: In 2016, orthopaedic surgeons received nearly USD 300 million from industry, with the top 10% of recipients making more than 95% of the total amount. The degree to which gender may be associated with industry compensation has not been well explored; however, this may be confounded by a number of variables, including academic productivity, experience, and other factors. We wished to explore the variability in payment distribution by gender after controlling for these factors. Questions/purposes: (1) Do men or women academic orthopaedic surgeons receive more payments from industry? (2) To what degree do any observed differences between the genders persist, even after accounting for identifiable factors, including academic rank, scholarly productivity, regional location of university, subspecialty selection as identified by fellowships completed, and years since completion of residency? Methods: This study was a cross-sectional retrospective analysis of surgeons practicing in orthopaedic surgery academic departments in the United States. Academic orthopaedic surgery departments were identified using the Fellowship and Residency Electronic Interactive Database. Publicly available data on gender, academic rank, scholarly productivity, regional location of university, fellowships completed, and years since residency graduation were collected from institutional websites. Industry funding data for 2016 were obtained from the Centers for Medicare & Medicaid Services Open Payments Database, and scholarly productivity data through 2017 were collected from Scopus. A total of 2939 academic orthopaedic surgeons, 2620 (89%) men and 319 (11%) women from 126 programs were identified. Men and women surgeons were different in most of the variables collected, and all except region of university were associated with differences in industry payments. Results: The median payment for men surgeons was greater than that for women (USD 1027 [interquartile range USD 125-USD 9616] versus USD 177 [IQR USD 47-USD 1486]; difference of medians, USD 850; p < 0.001]. After accounting for potentially confounding variables like faculty rank, years since residency, H-index and subspecialty choice, women faculty members still received only 29% of payments received by otherwise comparable men orthopaedists (beta coefficient for gender = 0.29 [95% CI 0.20 to 0.44; p < 0.001]). Conclusions: Women academic orthopaedic surgeons received only 29% of the industry payments received by men, even after controlling for faculty rank, years since residency, H-index, and subspecialty selection. This gender-related disparity may hinder the career advancement of women orthopaedic surgeons. Clinical Relevance: Increased transparency by companies can help guide orthopaedic surgeons who wish to receive industry funding.
