Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.9% of the total across 712 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 36 manufacturers, the largest accounting for just 17.2% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $4,202 and has fallen 99.3% since, to $30 in 2024.
Across 712 payments — averaging $19.90 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
