Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $94,179 of the $134,564 with a category attached, or 70.0%. Takeda Pharmaceuticals U.S.A., Inc. accounts for 60.7% of it on its own, with 11 other manufacturers making up the rest. 2025 is the largest year on record at $47,971, more than ten times the $1,292 reported in 2019. Among sleep medicine clinicians in CA 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 95 payments — averaging $1416.46 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
