Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.2% of the total across 244 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 35 manufacturers, the largest accounting for just 14.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,207 and has fallen 98.7% since, to $15 in 2023. Among internal medicine clinicians in VA with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 244 payments — averaging $15.96 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
