Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.4% of the total across 101 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 31 manufacturers, the largest accounting for just 22.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $564 and has fallen 68.3% since, to $179 in 2024.
Across 101 payments — averaging $19.20 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
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.
