Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.2% of the total across 250 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 11.6% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $1,369 and has fallen 58.7% since, to $565 in 2022.
Across 250 payments — averaging $15.66 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
