Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 95.6% of the total across 93 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 20 manufacturers reported payments, led by AbbVie at 42.5% of the total. Reporting peaked in 2022 at $555 and has fallen 96.7% since, to $18 in 2025. That places this record below the midpoint for gastroenterology clinicians in CA, where the typical reported total is $1,790.
Across 93 payments — averaging $24.49 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
