Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.7% of the total across 140 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 15 manufacturers, the largest accounting for just 23.3% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,467 and has fallen 94.8% since, to $77 in 2023. That places this record below the midpoint for gastroenterology clinicians in MI, where the typical reported total is $1,620.
Across 140 payments — averaging $16.89 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
