Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 139 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 15 manufacturers reported payments, led by Gilead at 37.2% of the total. Among medical clinicians in NY 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 139 payments — averaging $37.00 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

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.
