Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 93.7% of the total across 89 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 36 manufacturers, the largest accounting for just 18.0% — the pattern of someone who eats at a lot of different presentations. Among registered nurse 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 89 payments — averaging $37.83 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
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.
