Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $119,875 of the $132,729 with a category attached, or 90.3%. AstraZeneca accounts for 98.7% of it on its own, with 14 other manufacturers making up the rest. Reporting peaked in 2022 at $68,437 and has fallen 99.8% since, to $117 in 2025. Among nephrology clinicians in AL 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 299 payments — averaging $443.91 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.
