Plain English Summary

Background and study aims
Stroke is a common medical emergency and time-critical treatments reduce the chance of disability or death. About 1 in 10 patients are suitable for an emergency operation to remove blood clots blocking large arteries in the brain (known as thrombectomy) which greatly improves their chances of recovery. However, this operation is only available at specialist regional hospitals and unless patients live nearby, they are first admitted to their local hospital and must be transferred for treatment. A transfer typically delays thrombectomy by at least 90 minutes and reduces its benefit. Faster treatment might occur if patients could attend specialist regional hospitals directly but at present no accurate assessment or portable test exists to guide ambulance staff to make a confident diagnosis of stroke, or to determine that thrombectomy is needed.
In an earlier research project, a specialist prehospital redirection pathway was developed which involves communication between ambulance practitioners and specialist hospital thrombectomy staff to decide whether the emergency operation is likely to be required, followed by direct admission to the specialist hospital if this is the case. This study will now test the impact of this new pathway.

Who can participate?
All suspected and confirmed acute stroke patients from participating geographical regions will be involved

What does the study involve?
Ambulance stations (work bases for ambulance practitioners) or ambulance staff teams will be assigned at random to use the new pathway or to continue with current standard care when attending suspected stroke patients. Data will be collected about thrombectomy treatments and other aspects of emergency medical care received which will be compared between the two groups.

What are the possible benefits and risks of participating?
This study is testing whether a new emergency care pathway improves access to thrombectomy treatment for some people. The pathway may result in faster treatment and better recovery after stroke but this is not yet known.

Where is the study run from?
Newcastle University (UK)

When is the study starting and how long is it expected to run for?
August 2021 to July 2026

Who is funding the study?
National Institute for Health Research (UK)

Scientific titleSpecialist pre-hospital redirection for ischaemic stroke thrombectomy (SPEEDY): a cluster randomised controlled trial with included health economic and process evaluations

Study hypothesisThe aim of the study is to determine the clinical and cost-effectiveness of a novel specialist prehospital redirection pathway intended to facilitate thrombectomy treatment for acute stroke.
Ethics approval(s)Approved 26/06/2022, North East - Newcastle & North Tyneside 1 Research Ethics Committee (NHSBT Newcastle Blood Donor Centre, Holland Drive, Newcastle upon Tyne, NE2 4NQ, UK; +44 (0)207 1048091; newcastlenorthtyneside2.rec@hra.nhs.uk), ref: 22/NE/0103
ConditionSuspected and confirmed acute stroke
InterventionThis research study is a multicentre cluster randomised controlled trial with included health economic and process evaluations. The intervention to be evaluated is a new pathway which involves communication between ambulance and specialist hospital staff to select patients for direct admission to a specialist regional hospital who are likely to need emergency thrombectomy treatment. Clusters will be ambulance stations (work bases for ambulance practitioners) or ambulance staff teams which prior to the start of the study will be assigned at random to use the new pathway or to continue with current standard care when attending suspected stroke patients.
Intervention typeOther
Primary outcome measureData collected from routine healthcare sources throughout the study period:
1. Thrombectomy rate
2. The time from stroke symptom onset to thrombectomy (when thrombectomy is received)
Secondary outcome measuresData collected from routine healthcare sources throughout the study period:
1. Key emergency care time intervals
2. Receipt of and time to thrombolysis treatment
3. Stroke severity 24 hours post reperfusion treatment (NIHSS)
4. Length of hospital stay
5. Dependency at discharge (mRS)

Target number of participantsPlanned Sample Size: 80000; UK Sample Size: 80000
Participant inclusion criteria1. An ambulance practitioner from a randomised station/team attended the incident
2. Conveyance was to either a local stroke hospital which refers patients to the participating specialist regional hospital, or directly to the participating specialist regional hospital
3. Acute stroke was suspected by the attending ambulance practitioner (i.e. Face, Arm, Speech Test (FAST) positive or any observed new focal neurological symptoms which indicated acute stroke according to the ambulance practitioner’s clinical judgement) OR acute stroke was diagnosed following arrival at a participating hospital irrespective of ambulance practitioner initial judgement of symptom cause
Participant exclusion criteriaDoes not meet the inclusion criteria
