Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $118,586 of the $147,837 with a category attached, or 80.2%. It is spread thinly across 11 manufacturers, the largest accounting for just 22.1%. Reporting peaked in 2023 at $32,031 and has fallen 69.1% since, to $9,900 in 2025. Among hematology clinicians in WA 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.

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.
