Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.6% of the total across 196 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 22 manufacturers reported payments, led by AbbVie at 26.7% of the total. 2025 is the largest year on record at $1,824, more than ten times the $24 reported in 2022. Among physician assistant 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 196 payments — averaging $17.35 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
