Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.4% of the total across 188 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 24 manufacturers reported payments, led by Tris Pharma Inc at 26.6% of the total. Reporting peaked in 2024 at $1,230 and has fallen 62.2% since, to $465 in 2025. Among pediatrics clinicians in PA 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 188 payments — averaging $18.45 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
