Adventist Health and Rideout cuts stroke transfer times 44% with Viz.ai AI-powered care coordination

Adventist Health and Rideout, a regional primary stroke centre, faced manual bottlenecks that delayed stroke care in regional settings. The complex transfer process for large vessel occlusion (LVO) stroke patients to a comprehensive stroke centre (CSC) resulted in average door-in-door-out (DIDO) times of 202 minutes, well above the US Joint Commission's 120-minute benchmark.

The facility implemented a comprehensive quality improvement initiative combining the Viz.ai platform, a formal CSC partnership, and standardised transfer protocols. Viz.ai provided real-time imaging analysis and automated care coordination, replacing manual workflows with automated LVO identification, team activation, and interhospital communication.

Average DIDO times fell from 202 minutes to 113 minutes — a 44% reduction that beat the 120-minute national benchmark by nearly 6%. Time from CTA completion to LVO detection dropped by 84%, and care-team notification times fell from 45 minutes to just 7 minutes.

• Automating LVO detection and care-team notification can eliminate the largest manual delays in regional stroke transfer workflows.
• Combining AI tooling with standardised protocols and CSC partnerships produces compounding time savings beyond what technology alone achieves.
• Regional hospitals can meet or exceed national stroke benchmarks (AHA-GWTG, Joint Commission) through AI-assisted workflow redesign without requiring a major facility upgrade.
