Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $200,978 of the $316,090 with a category attached, or 63.6%. 8 manufacturers reported payments, led by Viiv Healthcare Company at 48.2% of the total. Reporting peaked in 2019 at $144,962 and has fallen 93.7% since, to $9,182 in 2025. Among infectious disease clinicians in CA 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.

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.
