Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.6% of the total across 274 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 39 manufacturers, the largest accounting for just 11.6% — the pattern of someone who eats at a lot of different presentations. 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 274 payments — averaging $18.23 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
