Ardent Health (NYSE: ARDT) announced that its physicians and advanced practice providers have surpassed 1 million patient encounters supported by Ambience Healthcare's ambient AI platform since the company launched an enterprise-wide deployment in September 2025.

According to the company, Ardent-affiliated clinicians use the technology in 87% of ambulatory encounters across specialties. The company said this rate exceeds industry benchmarks of roughly 40% to 45% cited in peer-reviewed and independent studies. Providers using the platform save an average of more than three hours per week in documentation time, based on electronic health record data.

The technology automatically generates clinical documentation during patient visits, reducing time spent on notes, chart completion, and after-hours work.

"Reaching a million encounters is a testament to our physicians and advanced practice providers who have embraced this technology as a way to spend less time documenting and more time connecting with patients," said Brad Hoyt, MD, chief medical information officer for Ardent Health.

The one-millionth encounter was completed by Jennie Zheng, MD, a family medicine physician with UT Health East Texas in Tyler, Texas. According to the press release, Dr. Zheng uses the platform for 83% of her encounters and has reduced her documentation time by 53%, from 135 minutes to 64 minutes per eight hours of appointments.

Since the enterprise rollout began, the technology has supported more than 418,000 unique patients across Ardent's ambulatory network. Ardent Health operates 30 acute care hospitals and more than 280 sites of care across six states.
