Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $101,544 of the $142,110 with a category attached, or 71.5%. Abbott accounts for 99.9% of it on its own, with 1 other manufacturer making up the rest. Reporting peaked in 2022 at $55,826 and has fallen 98.0% since, to $1,111 in 2025. Among neonatal-perinatal medicine clinicians in TN 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 294 payments — averaging $483.37 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.
