Transfer Delays Tied to Worse Acute Stroke Intervention Results

Why It Matters

Reducing DIDO time can directly improve stroke survival and functional recovery, making it a critical performance target for emergency and stroke networks.

Key Takeaways

• DIDO >90 min linked to worse discharge outcomes.
• Odds of thrombectomy drop as DIDO time increases.
• Only 26% of transfers meet 90‑minute DIDO target.
• Longer DIDO amplifies complications for patients receiving thrombectomy.
• HI‑SPEED trial aims to reduce DIDO delays.

Pulse Analysis

The study leverages the Get With The Guidelines‑Stroke registry to quantify how every minute spent in the originating emergency department erodes the therapeutic window for acute ischemic stroke. By stratifying DIDO intervals, researchers demonstrated a clear dose‑response relationship: patients delayed beyond 90 minutes experienced a 29‑70% increase in odds of worse functional scores, while their chances of receiving endovascular thrombectomy fell by up to 65%. These data reinforce the long‑standing "time is brain" principle, extending it from door‑to‑needle metrics to inter‑hospital transfer workflows.

For health systems, the implications are operational as well as clinical. Primary‑stroke‑center protocols must prioritize rapid neuro‑imaging, early telestroke consultation, and pre‑arranged transport pathways to keep DIDO times under the 90‑minute threshold. The analysis also highlights variability in ambulance availability and regional logistics, suggesting that bundled process improvements—such as dedicated stroke transport units or real‑time bed‑matching platforms—could close the gap. Hospitals that embed DIDO targets into performance dashboards are likely to see measurable gains in thrombectomy rates and reduced complication profiles.

Looking ahead, the ongoing HI‑SPEED trial seeks to identify specific barriers and test targeted interventions, from streamlined imaging sequences to automated hand‑off tools. As payers and accreditation bodies increasingly tie reimbursement to stroke quality metrics, DIDO performance will become a benchmark akin to door‑to‑needle times for IV tPA. Stakeholders that invest now in data‑driven workflow redesign will not only improve patient outcomes but also position themselves competitively in value‑based care models.
