Ambient AI Embedded Directly in EHR Systems at Scale
#1Nuance DAX Copilot is embedded as a native module inside Epic — the EHR platform used by 77% of U.S. hospitals and over 305 million patients — meaning ambient AI transcription is not a third-party add-on but a first-party feature of the dominant health IT infrastructure. Microsoft (Nuance's parent since 2022) has made DAX a strategic pillar of its healthcare cloud business, with over 400 health organizations deployed as of early 2026. Simultaneously, Commure Ambient (formerly Augmedix) processed 43 million patient interactions at HCA Healthcare alone in 2025, and Oracle Health (Cerner) has embedded its own ambient AI layer into its EHR platform serving 30% of U.S. hospitals — meaning there is no major EHR vendor that is not now committed to ambient AI as core infrastructure.
