Payments from drug & device makers
What this record shows
Almost everything reported here is food and beverage — 98.1% of the total across 140 separate payments, which is the pattern of a clinician who attends manufacturer presentations rather than one with a consulting arrangement. 25 manufacturers reported payments, led by GSK at 25.4% of the total. Reporting peaked in 2021 at $1,358 and has fallen 98.0% since, to $27 in 2023. That places this record below the midpoint for allergy & immunology clinicians in IN, where the typical reported total is $4,393.
Across 140 payments — averaging $28.33 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
