Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 93.6% of the total across 34 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 11 manufacturers, the largest accounting for just 20.5% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $329 and has fallen 91.9% since, to $26 in 2023. That places this record below the midpoint for hematology & oncology clinicians in CA, where the typical reported total is $3,371.
Across 34 payments — averaging $14.46 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
