Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.9% of the total across 232 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 26 manufacturers, the largest accounting for just 15.5% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $956 and has fallen 60.6% since, to $377 in 2025. Among pediatrics clinicians in TN 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 232 payments — averaging $18.65 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
