Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.0% of the total across 94 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 30 manufacturers, the largest accounting for just 11.5% — the pattern of someone who eats at a lot of different presentations.
Across 94 payments — averaging $22.66 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
