Tarras ES, Marshall DC, Rosenzweig K, et al. - Researchers undertook this retrospective, population-based, observational cohort study to analyze trends in industry payments to medical oncologists from 2014 to 2019 and see if the execution of the Open Payments program impacted the frequency or value of payments or any shift in industry-oncologist financial interactions. Data from the National Plan and Provider Enumeration System were used to assess Open Payments reports of industry payments made in 2014 to 2019 to a cohort of licensed medical oncologists practicing in the US in 2014. Findings revealed a reduction in the number of medical oncologists accepting industry payments; however, in a relatively small number of medical oncologists accepting higher payment values over time, high-value industry payments have been consolidated. A shift in the nature of payments toward consulting has been noted. These data underscore the limitations of transparency without accountability.
