Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.9% of the total across 175 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 16.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2024 at $1,518 and has fallen 70.2% since, to $452 in 2025.
Across 175 payments — averaging $21.67 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
