Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 151 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 17.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $628 and has fallen 55.5% since, to $279 in 2025. Among pediatrics clinicians in AZ with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 151 payments — averaging $17.36 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
