Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 189 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 21 manufacturers, the largest accounting for just 17.3% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for gastroenterology clinicians in AZ, where the typical reported total is $3,568.
Across 189 payments — averaging $15.96 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
