What this record shows
Almost everything reported here is food and beverage — 96.0% of the total across 123 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 22 manufacturers, the largest accounting for just 19.1% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2022 at $748 and has fallen 71.5% since, to $213 in 2023.
Across 123 payments — averaging $18.62 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
