Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.8% of the total across 511 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 33 manufacturers, the largest accounting for just 16.0% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $3,254 and has fallen 99.4% since, to $19 in 2025.
Across 511 payments — averaging $14.24 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
