Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $937 of the $1,152 with a category attached, or 81.3%. It is spread thinly across 19 manufacturers, the largest accounting for just 20.3% — 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 38 payments — averaging $30.31 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
