Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 99.7% of the total across 260 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. It is spread thinly across 19 manufacturers, the largest accounting for just 13.9% — the pattern of someone who eats at a lot of different presentations. 2025 is the largest year on record at $2,875, more than ten times the $259 reported in 2023. Among psychiatric/mental health clinicians in MI 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 260 payments — averaging $21.09 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
