Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 91.3% of the total across 112 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 16 manufacturers reported payments, led by Actelion Pharmaceuticals US, Inc. at 25.6% of the total. Among hospitalist clinicians in IL with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 112 payments — averaging $24.48 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Who reported the general payments

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
