Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 100.0% of the total across 2 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. Mallinckrodt Enterprises LLC accounts for 78.7% of it on its own, with 1 other manufacturer making up the rest. That places this record below the midpoint for gastroenterology clinicians in WA, where the typical reported total is $517.
Across 2 payments — averaging $46.30 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
- Mallinckrodt Enterprises LLC$73
- Medtronic$20
Across 228 payments — averaging $7671.34 each. Payments tied to a research study. These frequently flow through the physician to a hospital or research institution rather than to the physician personally.
