Has Charles Willis received payments from drug or device companies?

Does a payment mean Charles Willis did something wrong?

No. Federal law requires drug and device makers to report almost every transfer of value to a physician, including a $14 sandwich at a lunch presentation. Consulting fees, research funding and royalties to device inventors are ordinary, legal parts of medicine. This site reports what was disclosed; it makes no allegation.

Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 98.7% of the total across 165 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 46 manufacturers, the largest accounting for just 9.8% — the pattern of someone who eats at a lot of different presentations. Reporting peaked in 2019 at $1,626 and has fallen 99.0% since, to $16 in 2023.
