Increasing Consulting Fee Payments to Interventional Radiologists in the United States From Industry, 2014 to 2018: Analysis of the Open Payments Database

Purpose: To evaluate trends in consulting fees from industry to US-based interventional radiologists from 2014 to 2018.

Methods: Payments to interventional radiologists from January 1, 2014, to December 31, 2018, were analyzed from the CMS Open Payments Database. Payment type, total consulting fee payments per year and total payment per physician, and aggregate payments per company were analyzed before and after adjustment for outliers.

Results: Over the 5-year period, a total of $79.8 million was paid from industry to interventional radiologists, of which $17.6 million (22.1%) represented consulting fees. Per physician, the median total yearly amount paid as consulting fees was $5,050. Consulting fees increased from a total of $2.8 million per year in 2014 to $4.6 million per year in 2018 (+65%). After adjustment for outliers, consulting fee payments rose from $1.8 million to $3.5 million (+94%). The number of physicians paid each year increased from 156 to 219 physicians and the median payment increased from $4,327 to $5,419. Before ($5,118,966) and after adjustment, Sirtex Medical Inc paid the highest total aggregate consulting fee payments per year to self-identified interventional radiologists. After expansion to include both interventional and diagnostic radiologists by specialty type, Merck Sharp & Dohme Corp ($21,505,861) and Pfizer Inc ($11,798,255) followed by Sirtex Medical Inc ($8,276,818) paid the highest total aggregate in consulting fees.

Conclusion: Total consulting fees to interventional radiologists increased between 2014 and 2018 by 65%, driven by both the increased number of physicians paid consulting fees and the increased average payment amount.
