Industry Payments Received by Residents During Training

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.

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.

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.

Specialty, sponsoring institutions' ownership (nonprofit, for-profit, federal government, local government, or state government), and the number of payments PDs accepted.

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.

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).

In this cross-sectional, retrospective study, receipt of industry payments by residents was associated with specialty, institutional control, and PD behavior.
