Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.3% of the total across 93 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 35 manufacturers, the largest accounting for just 12.9% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for hematology & oncology clinicians in AZ, where the typical reported total is $6,870.
Across 93 payments — averaging $18.60 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
