Quarter Overview
Stroke Scale Score Distribution — Scale Type & LVO Risk Profile
Scale Type Used by Crews
eVitals.29 · Which screening tool crews are applying in the field
LVO Risk Stratification
LAMS ≥4 and RACE ≥5 suggest large vessel occlusion — drives destination decision
Scale Result Classification & Pre-Alert Funnel
Result Classification — All Scales Combined
Positive · Non-Conclusive · Negative · Pertinent Negative · Not Recorded
Pre-Alert Eligibility Funnel
Positive scale + within 24hr = eligible for pre-alert
Onset Time Window & Quarterly Trend
Time from Onset / LKW to EMS Arrival
Distribution across time windows — cases with onset documented
5-Quarter Compliance Trend
Stroke scale documentation rate — 95% target
Hospital Destination & Stroke Capability
Destination by Capability Tier
Where patients were transported — and what each facility can offer
LVO Routing Compliance & Bypass Summary
High-probability LVO patients (LAMS ≥4 / RACE ≥5) routed to thrombectomy-capable centers
