Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 28 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 7.8% — the pattern of someone who eats at a lot of different presentations. That places this record below the midpoint for pulmonary disease clinicians in MI, where the typical reported total is $1,164.
Across 28 payments — averaging $16.05 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
