Prevalence of Key Confounding Covariates in a Commercial Electronic Health Records Platform

Confounding adjustment in claims-based medical product safety surveillance is limited by incomplete clinical detail. This poster explores the utility of a large commercial electronic health record (EHR) platform (TriNetX Live™ USA Network) to supplement claims data by capturing key confounders—obesity, body mass index (BMI), smoking status, and blood pressure—across 2017 to 2023. It was presented at the 2025 ISPE Annual Meeting.
