When the COVID-19 pandemic struck, healthcare faced a critical bottleneck: massive amounts of lifesaving patient data were locked in isolated, incompatible electronic health record (EHR) silos. In this episode, we dive into how the National COVID Cohort Collaborative (N3C) engineered a groundbreaking "digital Rosetta Stone" to harmonize billions of clinical data points, permanently transforming the landscape of open science and medical informatics.
