Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $1,286 of the $1,663 with a category attached, or 77.3%. It is spread thinly across 28 manufacturers, the largest accounting for just 10.2% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $1,048, more than ten times the $20 reported in 2019. That places this record below the midpoint for hematology & oncology clinicians in SC, where the typical reported total is $4,020.
Across 41 payments — averaging $40.56 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
