How Banner Health Uses Claude to Reduce Physician Burnout with AI Documentation

Banner Health, one of the largest nonprofit health systems in the United States, identified a crisis hiding in plain sight: physician burnout driven not by patient care, but by paperwork. Physicians were spending 2–3 additional hours nightly on chart preparation after completing their shifts.

Oncologists bore the heaviest load. Preparing referrals required reviewing hundreds of pages of patient records, with 20% of hematology oncology documentation occurring between 6 PM and 6 AM—a pattern no health system could sustain.

Banner Health partnered with AWS to build BannerWise, an enterprise AI platform powered by Claude, deployed across 55,000 employees. The platform streamlined oncology chart preparation and transformed after-hours labor into efficient in-clinic workflows.

Deployment was completed within 30 days on AWS infrastructure with full privacy preservation. 85% of users reported significant time savings with improved accuracy. The system established the foundation for reducing provider administrative burden by 50% over four years.
