Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $8,000 of the $8,946 with a category attached, or 89.4%. It is spread thinly across 23 manufacturers, the largest accounting for just 16.8% — the pattern of someone who eats at a lot of different presentations. Among physician assistant 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 311 payments — averaging $28.77 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
