Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 91.3% of the total across 100 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 25 manufacturers, the largest accounting for just 21.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $1,586 and has fallen 98.3% since, to $28 in 2024.
Across 100 payments — averaging $28.71 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
