Background: Industry partnerships offer financial incentives, prestige, and can facilitate career advancement in oncology. However, not all physicians may have equal access to these opportunities. We hypothesized that physicians who are underrepresented in the medical oncology workforce based on race, ethnicity, and gender receive less industry funding. Methods: All US medical oncologists (MOs) who received ≥1 industry research payment between 2016 and 2020 according to the Open Payments database were included in this retrospective study. Information extracted from Open Payments included MO’s name, institution, research payments (i.e. funding for a research project where the physician is a Principle Investigator), and general payments (i.e. fees not associated with research, such as consulting and travel fees). Additional web searches were conducted using institutional websites, NPPES NPI registry, LinkedIn, Doximity, Scopus, and NIH RePORTER to determine each MO’s race, ethnicity, sex, academic rank, degrees, h-index, institutional NIH research funding rank, and individual receipt of NIH funding. Log-linear regression was performed to identify associations of both industry and general payment data. Results: Of 7,542 physicians meeting inclusion criteria, 69% were male, 65% White, 29% Asian, 2% Black, and 4% Hispanic, which is comparable to the American Medical Association Physician Masterfile figures for MO. The median sum research payment and general payment was $134,857 and $11,537 per physician respectively. Significantly higher mean research payments were associated with an MS (+72%; P = 0.003) or PhD degree (+30%; P = 0.009), h-index (+3%; P < 0.001), top 50 institution rank by NIH funding (+44%; P < 0.001), and associate professor rank (+95%; P < 0.001). Significantly lower mean research payment were observed for Black physicians (-36%; P = 0.022) and those with non-academic affiliation (-47%; P < 0.001). No significant association was observed between sex and research payment. Significantly higher mean general payments were associated with male sex (+46%; P < 0.001), MS degree (+171%; P < 0.001), h-index (+2%; P < 0.001), and Asian race (+72%; P < 0.001). Significantly lower mean general payments were associated with an affiliation with a non-academic practice (-31%; P = 0.012). Conclusions: Black physicians received smaller sums of industry research payments compared to White physicians. Female sex was associated with decreased general payments compared to male sex. Further exploring the underlying mechanisms determining access to industry payments may help facilitate greater equity and inclusivity in oncology.
