Payments from drug & device makers

What this record shows

Almost everything reported here is food and beverage — 100.0% of the total across 163 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 16 manufacturers, the largest accounting for just 22.2% — the pattern of someone who eats at a lot of different presentations.
