Industry Payments Received by Residents During Training.

Importance: Those responsible for medical education-specialties, sponsoring institutions, and program directors (PD)-are independently associated with the professional identity formation of the trainees with respect to potential conflicts of interest. Objective: To identify the relative degree to which factors in the training environment are associated with resident acceptance of payments from pharmaceutical and medical device companies. Design, Setting, and Participants: Cross-sectional, retrospective study of residents enrolled in the 3 largest primary-care specialties (internal medicine [IM], family medicine [FM], obstetrics and gynecology [OBGYN]) and 3 largest surgical disciplines (general surgery [GS], orthopedic surgery, and urology) during academic year 2020 to 2021. All analyses were conducted January through August 2023. Exposures: Specialty, sponsoring institutions' ownership (nonprofit, for-profit, federal government, local government, or state government), and the number of payments PDs accepted. Main outcomes and measures: Modified Poisson regression assessed the relative risk of ownership, specialty, and PD behavior on residents' acceptance of industry payments as recorded in the Open Payments Program (OPP) database. Results: In total, there were 124 715 residents in all training programs during 2020 to 2021, 12% of whom received payments totaling $6.4 million. There were 65 992 residents in training during 2020 to 2021 in the 6 specialties evaluated in this study, with 4438 in orthopedics, 1779 in urology, 9177 in GS, 5819 in OBGYN, 14 493 in FM, and 30 286 in IM. OPP records $3.9 million in payments to the 8750 residents (13.4%) who received at least 1 industry payment. The record of all payments to residents in OPP totals $6.4 million. Compared with residents in federal sponsoring institutions, those affiliated with for-profit institutions were 3.50 (95% CI, 2.32-5.28) times more likely to accept industry payments, while those affiliated with nonprofit organizations were 2.00 (95% CI, 1.36-2.93) times more likely to accept payments. Compared with IM, residents in each of the following specialties have an elevated risk of accepting payments: orthopedics, 3.21 (95% CI, 2.73-3.77) times; urology, 2.95 (95% CI, 2.44-3.56) times; GS, 1.21 (95% CI, 1.00-1.45) times; OBGYN, 1.30 (95% CI, 1.05-1.62) times. The difference in the risk of accepting a payment between FM and IM residents was not statistically significant. The number of payments PDs accepted slightly elevated the risk of residents to accept a payment by 1.01 (95% CI, 1.01-1.01). Conclusions and relevance: In this cross-sectional, retrospective study, receipt of industry payments by residents was associated with specialty, institutional control, and PD behavior.
