Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.2% of the total across 308 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 28 manufacturers, the largest accounting for just 19.6% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $2,112 and has fallen 57.0% since, to $907 in 2022.
Across 308 payments — averaging $14.73 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
