Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.8% of the total across 196 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 22 manufacturers, the largest accounting for just 20.3% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $3,219 and has fallen 99.5% since, to $17 in 2025.
Across 196 payments — averaging $17.39 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.
