Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $7,854 of the $9,743 with a category attached, or 80.6%. It is spread thinly across 21 manufacturers, the largest accounting for just 20.6% — the pattern of someone who eats at a lot of different presentations. Among optometrist 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 88 payments — averaging $110.72 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
