Disconnected by Design: How EHR Fragmentation Is Silently Compromising Patient Safety Across the US
Across the United States, competing electronic health record systems operate in near-total isolation from one another, creating dangerous blind spots in patient care.

This investigation examines the regulatory, technical, and financial forces sustaining these silos, and the patient harm accumulating in their shadow.
