Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 46 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 22 manufacturers, the largest accounting for just 20.7% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $563 and has fallen 68.2% since, to $179 in 2025.
Across 46 payments — averaging $20.75 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
