Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 96.6% of the total across 91 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 18 manufacturers, the largest accounting for just 14.3% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $1,468, 9.5 times the $154 reported in 2022. That places this record below the midpoint for hematology & oncology clinicians in PR, where the typical reported total is $10,882.
Across 91 payments — averaging $31.01 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.
