Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 94.7% of the total across 31 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 16 manufacturers, the largest accounting for just 19.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $847 and has fallen 82.4% since, to $149 in 2024. That places this record below the midpoint for hematology & oncology clinicians in SC, where the typical reported total is $4,020.
Across 31 payments — averaging $92.04 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.
