Payments from drug & device makers
What this record shows
This record is dominated by consulting fees: $2,114,065 of the $2,115,118 with a category attached, or 100.0%. 5 manufacturers reported payments, led by Pfizer at 47.6% of the total. Among infectious disease clinicians in PA 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 90 payments — averaging $23,501 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.
