Scene-to-door time and stroke thrombectomy

Impact of prehospital scene-to-door time on functional outcomes after endovascular thrombectomy: insights from a regional stroke network
BMC Emergency Medicine · 2026-07-27 · Added 25 October 2026

A single-centre Japanese cohort of 121 stroke thrombectomy patients transported directly from scene found scene-to-door time was only associated with outcome in patients with pre-stroke disability, where longer intervals were linked to lower odds of a favourable 90-day outcome (aOR 0.91; ROC cut-off 14 minutes in that subgroup).

Study type
Cohort
Design
Retrospective single-centre cohort, comprehensive stroke centre (2018–2023)
Participants
121 patients transported directly from scene to EVT
Main finding
In patients with pre-stroke disability (mRS ≥1), longer scene-to-door time was associated with lower odds of favourable 90-day outcome (adjusted OR 0.91, 95% CI 0.81–0.98; ROC cut-off 14 min); no significant association in the overall cohort (AUC 0.57)
Caveat
Single centre, only 121 patients, retrospective design
Bottom line
Hypothesis-generating

Why it matters in Australia (Medium relevance). Scene-to-door intervals are exactly what Australian crews influence on stroke jobs, but this comes from one Japanese comprehensive stroke centre with its own bypass and activation pathways.

Learning goal

Weigh how on-scene time affects functional outcomes in stroke patients with pre-existing disability needing thrombectomy.
