Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 96.8% of the total across 118 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 17 manufacturers, the largest accounting for just 14.4% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2021 at $981 and has fallen 98.0% since, to $19 in 2023. That places this record below the midpoint for dermatology clinicians in HI, where the typical reported total is $2,082.
Across 118 payments — averaging $23.78 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
