Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 94 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 20 manufacturers, the largest accounting for just 24.0% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,019 and has fallen 93.3% since, to $68 in 2021.
Across 94 payments — averaging $15.52 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
