Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 95 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 18 manufacturers, the largest accounting for just 19.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $1,236 and has fallen 86.7% since, to $165 in 2024. Among nurse practitioner 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 95 payments — averaging $33.26 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
