Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.5% of the total across 127 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 Atricure, Inc. at 26.4% of the total. Reporting peaked in 2019 at $1,342 and has fallen 97.6% since, to $33 in 2025. That places this record below the midpoint for medical oncology clinicians in PA, where the typical reported total is $2,595.
Across 127 payments — averaging $17.86 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
