Case Study #1: Kaiser Permanente - Largest Healthcare AI Deployment
Kaiser Permanente made healthcare history with the largest generative AI rollout ever—and their fastest technology implementation in over 20 years.
📊 Kaiser Permanente Results
| Deployment Scale | 40 hospitals + 600+ medical offices |
| AI Solution | Abridge ambient documentation |
| Documentation Time | Reduced by 50%+ |
| Implementation Speed | Fastest in 20+ years |
| Physician Satisfaction | Significant improvement reported |
The Ambient AI Advantage
Kaiser's deployment of Abridge uses ambient AI to listen to patient-physician conversations and automatically generate clinical documentation. Physicians no longer spend hours typing notes—the AI captures everything in real-time.
Key insight: Kaiser evaluated this as a strategic priority because physician burnout directly impacts patient care quality and staff retention.
Case Study #2: Johns Hopkins Hospital - $4M Annual Savings
