Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $61,328 of the $87,191 with a category attached, or 70.3%. It is spread thinly across 27 manufacturers, the largest accounting for just 11.2%. Among emergency 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 90 payments — averaging $968.79 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
