Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.5% of the total across 86 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 12.0% — the pattern of someone who eats at a lot of different presentations. Among pediatrics clinicians in VA 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 86 payments — averaging $20.62 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
