Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.9% of the total across 126 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 18.2% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,345 and has fallen 98.9% since, to $14 in 2021.
Across 126 payments — averaging $14.25 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
