Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.9% of the total across 81 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 2022 at $722 and has fallen 89.4% since, to $77 in 2025.
Across 81 payments — averaging $31.02 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
