Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.5% of the total across 304 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 39 manufacturers reported payments, led by AbbVie at 24.6% of the total. Reporting peaked in 2022 at $1,488 and has fallen 51.5% since, to $722 in 2025. Among obstetrics & gynecology 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 304 payments — averaging $20.20 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
