Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 96.0% of the total across 44 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 12.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $316 and has fallen 92.4% since, to $24 in 2024.
Across 44 payments — averaging $17.76 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
