Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (55.5%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. 13 manufacturers reported payments, led by Vifor Pharma, Inc. at 46.0% of the total. Reporting peaked in 2023 at $30,860 and has fallen 78.2% since, to $6,742 in 2025. Among nephrology clinicians in OH with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 96 payments — averaging $1109.64 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
