Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 96.3% of the total across 113 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 18 manufacturers reported payments, led by Sanofi at 25.4% of the total. Reporting peaked in 2024 at $1,236 and has fallen 68.0% since, to $396 in 2025. Among nurse practitioner clinicians in CA 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 113 payments — averaging $26.07 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
