Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 164 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 30 manufacturers, the largest accounting for just 14.1% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $836 and has fallen 91.1% since, to $74 in 2024.
Across 164 payments — averaging $18.04 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
