Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 97.4% of the total across 153 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 21 manufacturers reported payments, led by AstraZeneca at 33.8% of the total. 2025 is the largest year on record at $1,791, more than ten times the $36 reported in 2020. Among pediatrics 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 153 payments — averaging $25.46 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
