ABSTRACT NUMBER: ESOC2026A1498 THE IMPACT OF PRE-HOSPITAL STROKE VIDEO TRIAGE IN THE EAST OF ENGLAND, UK AGAINST UK NATIONAL REGISTRY DATA

Abstract Background and aims Over 4500 patients have been managed via Pre-hospital Stroke Video Triage (PVT) in the East of England, UK. Every patient is recorded, facilitating a robust governance process and allowing for rich data collection. Methods From October 2024-December 2025 all PVT patients were analyzed against UK Sentinel Stroke National Audit Programme (SSNAP) data. A subset analysis of 3 hospital sites comparing hospital arrival to Hyper Acute Stroke Unit (HASU) admission was undertaken. Results 876 patients were analyzed. The average percentage of patients scanned within 1 hour of clock start increased from 57% to 92% and the median time between clock start and scan reduced from 50-minutes to 15-minutes. The percentage of all stroke patients given thrombolysis increased from 14% to 18% and the percentage of patients who were thrombolysed within 1 hour of clock start increased from 61% to 74%. Median time from clock start to thrombolysis reduced from 53-miniutes to 44-minutes. 7% of all analyzed patients were transferred for Mechanical Thrombectomy (MT), with the DIDO for PVT patients 26-minutes faster than the UK average. The average percentage of patients admitted to HASU within 4-hours of clock start increased from 67% to 96%, median time to HASU admission decreased from 3-hours 9-minutes to 1-hour 20-minutes. Conclusions PVT has positively influenced all analyzed SSNAP indicators across all live sites. A 9-minute reduction in thrombolysis represents an estimated 17.1million neurons saved for an acute stroke patient, highlighting the impact of PVT.
