Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 101 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 19 manufacturers, the largest accounting for just 23.2% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $518 and has fallen 91.9% since, to $42 in 2022.
Across 101 payments — averaging $13.68 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
