Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.4% of the total across 123 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 23 manufacturers, the largest accounting for just 15.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,174 and has fallen 89.4% since, to $125 in 2025. That places this record below the midpoint for sleep medicine clinicians in AL, where the typical reported total is $3,427.
Across 123 payments — averaging $20.18 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
