Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 92.3% of the total across 637 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Abbott accounts for 62.4% of it on its own, with 27 other manufacturers making up the rest. Reporting peaked in 2022 at $2,901 and has fallen 99.0% since, to $29 in 2025.
Across 637 payments — averaging $15.14 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.
