Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 133 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 19 manufacturers reported payments, led by AstraZeneca at 24.1% of the total. Among nurse practitioner clinicians in MA 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 133 payments — averaging $22.59 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
