Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 92.1% of the total across 307 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 27 manufacturers, the largest accounting for just 22.3% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $2,556 and has fallen 99.0% since, to $26 in 2021. Among internal medicine 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 307 payments — averaging $14.97 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.
