Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 159 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 20 manufacturers, the largest accounting for just 22.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $727 and has fallen 98.0% since, to $15 in 2023.
Across 159 payments — averaging $13.19 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
