Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.9% of the total across 149 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 21 manufacturers, the largest accounting for just 18.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,966 and has fallen 98.6% since, to $28 in 2021.
Across 149 payments — averaging $16.18 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
