Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $187,734 of the $206,091 with a category attached, or 91.1%. AbbVie accounts for 63.9% of it on its own, with 10 other manufacturers making up the rest. Among pediatric gastroenterology clinicians in CA with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 222 payments — averaging $928.34 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
