Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 276 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 32 manufacturers, the largest accounting for just 23.9% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $1,423 and has fallen 97.4% since, to $37 in 2023. Among family medicine clinicians in IL 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 276 payments — averaging $16.13 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
