Abstract
BACKGROUND: Physicians have increasingly adopted Twitter as a discussion and distribution platform for oncology research. While the influence of financial conflicts of interests (FCOI) on medical research is well documented, their role in the dissemination of research on social media platforms is not well known. In this study, we sought to evaluate the FCOIs of physicians followed by the top three oncology journals on Twitter. MATERIALS AND METHODS: We used the Open Payments Search Tool ( https://openpaymentsdata.cms.gov ) to assess FCOIs between 2016 and 2021 of United States (US) physicians followed by three oncology journals (Journal of Clinical Oncology, The Lancet Oncology, and Annals of Oncology) on Twitter. RESULTS: Of 1914 Twitter accounts followed by the top three oncology journals on Twitter, 547 (28.6%) belonged to US physicians. Of these, 463 (84.6%) received general payments between 2016 and 2021. After excluding 30 US physicians currently in residency or fellowship, this percentage increased to 88.2% (n = 456/517). Combined, the median (interquartile range) general payment amount was $8100 ($200-90,000). Additionally, over $42 million in general payments were made between 2016 and 2021. CONCLUSION: Our findings offer insight on FCOIs between oncology journals and US physicians on Twitter. These findings may serve as the foundation for future research regarding optimal medical journal conduct on social media platforms.
