Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.0% of the total across 50 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 23 manufacturers, the largest accounting for just 13.8% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $613, 3.2 times the $191 reported in 2019. That places this record below the midpoint for hematology & oncology clinicians in PR, where the typical reported total is $10,882.
Across 50 payments — averaging $26.24 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.
