Analysis of Conflicts of Interest in Studies Related to Robotics in Gastrointestinal and Abdominal Wall Surgery

Abstract

BACKGROUND: Industry payments to physicians represent a potential conflict of interest (COI) and can influence the study conclusions. This study aimed to evaluate the accuracy of the COIs reported in major surgical journals. STUDY DESIGN: Studies with at least one American author published between 2016 and 2021 that discussed observational and intervention studies assessing robotic surgery were included in the analysis. The Centers for Medicare & Medicaid Services’ Open Payments database was used to collect the industry payments. A COI is defined as receiving funding from a robotics company while publishing research directly related to the company’s products. A COI statement was defined as disclosed (or accurate) if the disclosure statement for the study in question acknowledged funding from the robotics companies. A COI was defined as undisclosed (or inaccurate) if the disclosure statement for the study in question did not acknowledge funding from the robotics companies. RESULTS: A total of 314 studies and 1978 authors were analyzed. Only 13.6% of the studies had accurate COI statements, whereas the majority (86.4%) had inaccurate COI disclosures. Additionally, 48.9% of the authors who received funding of $10,000 to $100,000 failed to report this amount in their disclosures, and 18% of the authors who received funding of $100,000 or more did not report it in their disclosures. CONCLUSIONS: There was a significant discordance between the self-reported COI in gastrointestinal and abdominal wall surgeries. This study calls for continued efforts to improve the definitions of what constitutes a relevant COI and encourages a standardized reporting process. It is imperative for investigators to make accurate disclosure statements.
