Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 117 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 21 manufacturers, the largest accounting for just 20.2% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2023 at $1,038 and has fallen 94.4% since, to $58 in 2025. That places this record below the midpoint for cardiovascular disease clinicians in SC, where the typical reported total is $3,855.
Across 117 payments — averaging $20.37 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.
