Hospital Implementation of a Stroke Protocol for Emergency Evaluation and Disposition
A study testing HI-SPEED Protocol in people with Stroke, Acute and Ischemic Stroke, Acute, run by University of Chicago at 8 sites in United States.
Trial summary
Most stroke patients are initially evaluated at the closest hospital but some need to be transferred to a hospital that can provide more advanced care. The "Door-In-Door-Out" (DIDO) process at the first hospital can take time making transferred patients no longer able to get the advanced treatments. Read more about this study

About this study
Official title: Implementation of a Stroke Protocol for Emergency Evaluation and Disposition
Most stroke patients are initially evaluated at the closest hospital but some need to be transferred to a hospital that can provide more advanced care. The "Door-In-Door-Out" (DIDO) process at the first hospital can take time making transferred patients no longer able to get the advanced treatments. This study will help hospitals across the US "stand up" new ways to evaluate stroke patients, decide who needs to be transferred, and transfer them quickly for advanced treatment.
Read the detailed description
Nearly 800,000 people in the United States (US) each year experience acute stroke, which remains the leading cause of adult disability and 5th leading cause of death. Despite the proliferation of stroke centers nationwide, almost half of the US population lives beyond a 60-minute drive of a comprehensive stroke center (CSC) and many patients require inter-hospital transfer (IHT) from a non-CSC to a CSC. Building upon prior work to reduce door-in-door-out (DIDO) time at referring hospitals, this proposal entitled "Hospital Implementation of a Stroke Protocol for Emergency Evaluation and Disposition (HI-SPEED)" study seeks to (1) implement a novel, evidence-based, multi-component DIDO intervention in eight diverse stroke systems of care across multiple regions of the US and (2) conduct a dual evaluation of its effectiveness in reducing median DIDO time (primary outcome) and disability (secondary outcome) and of the fidelity and quality of implementation. The HI-SPEED study will definitively establish the effectiveness and generalizability of a multi-component evidence-based DIDO intervention and provide information about contextual adaptations for high-quality implementation and widespread dissemination. This study benefits from our well-established interdisciplinary expertise in stroke, emergency and prehospital medicine, systems and quality engineering, health services research, and strong multicenter research collaborations. Findings from HI-SPEED will have substantial implications for a wide range of hospitals and stroke systems of care worldwide.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
HI-SPEED ProtocolBehavioural
Also called HI-SPEED Bundle
The HI-SPEED Protocol or Bundle consists of 7 components including 1) stroke screening scales, 2) imaging pathways, 3) telestroke operations, 4) a best practice alert, 5) stroke team communication tool, 6) door-to-needle (thrombolysis) treatment pathway, and 7) a standardized hand-off tool. This protocol will be implemented at each participating health system in clusters of 2 health systems.

|---|---|---|
| Control Phase | No intervention | Pre-implementation of HI-SPEED Protocol |
| Implementation Phase | Active comparator | Post-Implementation of HI-SPEED Protocol Receives: Behavioral: HI-SPEED Protocol |

Questions about this trial
What is this clinical trial studying?
A study testing HI-SPEED Protocol in people with Stroke, Acute and Ischemic Stroke, Acute, run by University of Chicago at 8 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 20 May 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 8 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Shyam Prabhakaran, MD, MS (773-702-0080, shyam1@bsd.uchicago.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
DIDO time in acute ischemic stroke patients (time frame: Baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06094478, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2026.
