Smartphone-based Prehospital Stroke Triage Optimizes Workflow and Bridges the Off-hour Delays in Endovascular Thrombectomy.

The cohort included 721 patients (before, n = 262; after, n = 459).

Among Field Assessment Stroke Triage for Emergency Destination/JoinTriage-triaged patients (193/459, 42.0%), large vessel occlusion and endovascular thrombectomy rates were further enriched, reaching 35.8% and 24.4%, respectively.

Multivariate analysis identified the after period as an independent predictor of DTP < 60 min (adjusted odds ratio, 4.76; p = 0.019).

The trend toward prolonged DTP during off-hours observed in the before period (p = 0.054) was resolved in the after period.
