Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $7,386 of the $8,584 with a category attached, or 86.0%. It is spread thinly across 40 manufacturers, the largest accounting for just 20.8% — the pattern of someone who eats at a lot of different presentations. Among pediatric gastroenterology clinicians in TN with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 396 payments — averaging $21.68 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
