Trends in Industry-Sponsored Research Payments to Radiologist Principal Investigators

Area of Science:

• Medical Research Funding
• Radiology
• Healthcare Economics

Background:

• Industry-sponsored research payments are vital for medical science advancement.
• Payments are increasingly channeled through noncovered entities (NCEs) across specialties.
• Distribution patterns of research payments to radiologists were previously uncharacterized.

Purpose of the Study:

• To assess trends in research payments to radiologists from 2015 to 2024.
• To characterize the distribution of these payments, particularly those through NCEs.

Main Methods:

• Retrospective analysis of Open Payments program data (2015-2024).
• Examination of research payments accepted by radiologist principal investigators at NCEs.
• Application of linear regression and descriptive statistics for trend analysis.

Main Results:

• Total payments exceeded $824 million to nearly 3,000 radiologists.
• Annual payments rose 50%, with a 44% increase in payments to NCEs.
• Median payments per principal investigator at NCEs increased significantly; male radiologists received 88% of NCE payments in 2024.

Conclusions:

• Research payments to radiologists show a significant upward trend, largely due to increased NCE involvement.
• NCEs can be valuable partners in research when managed transparently, potentially improving patient care.
• Further investigation is needed to fully understand evolving research funding pathways in radiology.
