Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.8% of the total across 155 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 33 manufacturers, the largest accounting for just 11.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $705 and has fallen 90.4% since, to $67 in 2025.
Across 155 payments — averaging $16.10 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
