Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 105 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 17 manufacturers, the largest accounting for just 12.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,434 and has fallen 93.3% since, to $97 in 2024. That places this record below the midpoint for pain medicine clinicians in KY, where the typical reported total is $3,535.
Across 105 payments — averaging $18.64 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
