- Abstract
Key Points: Question: What is the sex distribution of industry payments in radiation oncology? Findings: In this cross-sectional study involving 4483 radiation oncologists, the proportion of radiation oncologists who received at least 1 industry payment in 2016 was substantially lower among female physicians (61.4%) than their male counterparts (70.4%). Across all payment types, female radiation oncologists received a smaller percentage of the total industry funding than their corresponding representation in these categories. Meaning: Distribution of corporate payments appears to show sex disparity in industry relationships among radiation oncologists; further investigation is needed to increase parity. Importance: Industry relationships are an important measure of professional advancement; however, the association between physician sex and industry payments in radiation oncology has not been described. Objective: To update the trends in the sex distribution of industry payments in radiation oncology. Design, Setting, and Participants: This retrospective cross-sectional study was conducted between July 1, 2018, and August 31, 2018. It used the publicly available Centers for Medicare & Medicaid Services (CMS) Open Payments program and CMS Physician and Other Supplier Public Use File databases to obtain 2016 industry payment data for US radiation oncologists who reported receiving industry funding in that year (n = 3052). Total monetary value, number of payments, and median payment amounts were determined for each sex in the following categories: research, consulting, honoraria, industry grants, royalty or license, and services other than consulting. Main Outcomes and Measures: Industry payment amounts among 3052 radiation oncologists who reported receiving payments in 2016; association of median payment with the types of payment by sex. Results: Of the total 4483 radiation oncologists who practiced in 2016, 1164 (25.9%) were female and 3319 (74.0%) were male. Industry payments were distributed among 3052 radiation oncologists (68.1%), of whom 715 (23.4%) were female and 2337 (76.6%) were male. The proportion of female radiation oncologists who received at least 1 industry payment was 61.4% (715 of 1164), whereas the proportion of their male counterparts was 70.4% (2337 of 3319). Across all payment types, female radiation oncologists received a smaller percentage of total industry funding than the percentage of female physicians represented in each category. The median payment value was smaller for female radiation oncologists in consulting (–$1000; 95% CI, −$1966.67 to $100.63; P =.005) and honoraria (–$500; 95% CI, −$1071.43 to $0; P =.007). This trend was also observed in research payments, but was not statistically significant (–$135.02; 95% CI, −$476.93 to $6.88; P =.08). Of the $1 347 509 royalty or license payments made to 72 physicians, none was for female radiation oncologists. Conclusions and Relevance: Distribution of industry payments appears to show sex disparity in industry relationships among radiation oncologists; this observation warrants further investigation to determine the underlying reasons and provide avenues for increased parity. This cross-sectional study uses the 2016 self-reported industry payment data from the Centers for Medicare & Medicaid Services (CMS) Open Payments and CMS Physician and Other Supplier Public Use File databases to investigate trends in funding distribution by sex among radiation oncologists.
