  A JAMA Network Open multicenter trial published in early 2026 demonstrated a 31% reduction in physician burnout and a 30% well-being improvement from ambient AI scribes, providing peer-reviewed clinical evidence that accelerated institution-wide rollout decisions and removed the last major adoption barrier (proof of clinician benefit).
