Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 95.6% of the total across 55 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 24 manufacturers, the largest accounting for just 13.5% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for hematology & oncology clinicians in CA, where the typical reported total is $3,371.
Across 55 payments — averaging $32.97 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.
