Payments from drug & device makers
What this record shows
The money is spread across several categories — grants (47.7%), travel and lodging and food and beverage — rather than concentrated in one kind of arrangement. 14 manufacturers reported payments, led by Abbott at 41.1% of the total. Reporting peaked in 2024 at $25,490 and has fallen 77.3% since, to $5,793 in 2025. Among internal medicine clinicians in MO with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 181 payments — averaging $248.84 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
