Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 109 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 17 manufacturers reported payments, led by AbbVie at 33.9% of the total. Reporting peaked in 2019 at $1,052 and has fallen 97.5% since, to $27 in 2022. That places this record below the midpoint for gastroenterology clinicians in SC, where the typical reported total is $2,692.
Across 109 payments — averaging $15.92 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
