Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.4% of the total across 292 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 31 manufacturers, the largest accounting for just 18.1% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2020 at $2,402 and has fallen 92.5% since, to $180 in 2022. Among geriatric medicine clinicians in CA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 292 payments — averaging $20.05 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
