The Association of Subspecialty and Sex with Industry Payments to Internal Medicine Physicians Who Recently Completed Training.

BACKGROUND

Financial relationships with drug and medical device companies may impact quality of care and academic research. However, little is known when and how these financial relationships develop among newly independent physicians who recently completed from residency or fellowship programs in internal medicine (IM).

OBJECTIVE

To compare patterns of industry payments among IM graduates.

DESIGN

Retrospective, observational cohort study.

SUBJECTS

IM graduates from residency or fellowship programs between January 2015 and December 2019.

MAIN MEASURES

We analyzed Open Payments reports made between July 2015 and June 2021 to recent graduates of U.S. Accreditation Council for Graduate Medical Education (ACGME)-accredited residency and fellowship programs in IM. The primary outcome was general payments accepted by these physicians, stratified by procedural (i.e., critical care medicine/pulmonary medicine, cardiac/cardiovascular disease, and gastroenterology) and non-procedural (i.e., infectious disease, general internal medicine, and other specialties) subspecialties. The secondary outcomes included general payments stratified by sex and age at residency or fellowship training completion.

KEY RESULTS

There were 41,669 IM physicians with a median age of 33.0 years. In the first 3 years after completion, the proportion of physicians accepting any general payments was 72.6%, 91.9%, and 86.8% in Critical Care Medicine/Pulmonary Medicine, Cardiac/Cardiovascular Disease, and Gastroenterology, compared to 56.1%, 52.6%, and 52.3% in Infectious Disease, General Internal Medicine, and Other Specialties (p<0.0001). After adjusting for confounding variables, the procedural group showed an increased hazard ratio (HR) for accepting any general payments and at least $5000 of general payments compared to the non-procedural group. The HRs of accepting any general payments in the procedural subspecialty were 2.26 (95% CI, 2.11-2.42) and 2.83 (95% CI, 2.70-2.97) in female and male physicians, respectively (p-value < 0.0001).

CONCLUSION

Industry financial relationships among newly independent physicians in IM exist immediately after completion of training and are influenced by subspecialty, sex, and age.
