Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.3% of the total across 86 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 22 manufacturers, the largest accounting for just 15.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $576 and has fallen 60.0% since, to $230 in 2023. That places this record below the midpoint for nephrology clinicians in SC, where the typical reported total is $1,778.
Across 86 payments — averaging $20.31 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.
