Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 92 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 15.3% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,569 and has fallen 99.1% since, to $14 in 2023. That places this record below the midpoint for allergy & immunology clinicians in CA, where the typical reported total is $2,148.
Across 92 payments — averaging $21.70 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
