Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to investigate whether a live stream video between the on-call neurologist and the emergency medical technicians can increase feasibility and performance of symptom-based prehospital stroke scales.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Treatment of stroke with either thrombolysis or thrombectomy is highly time-dependent (administration within 4.5 hours and 24 hours from symptom onset, respectively), and morbidity and mortality increase with time from symptom onset to treatment. Hence, prehospital evaluation and transport must be as accurate and rapid as possible in order to minimise time to treatment.

Different triage and transport paradigms for patients with suspected stroke are being investigated and multiple stroke scales have been coined in order to examine patients suspected of stroke in a prehospital setting. However, performance and feasibility vary greatly in different validation studies suggesting that those outcomes are greatly dependent on other factors i.e. acceptance amongst stakeholders, implementation process, patient segment etc. Some recent studies have shown promising results using video solutions between emergency medical services (EMS) personnel and on-call neurologist in examining patients suspected of stroke in the prehospital phase. The investigators will perform this trial to examine whether a video call assisted assessment of patients suspected of stroke in a prehospital setting can increase feasibility and performance of symptom-based prehospital stroke scales.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Standard Care

If the patient is eligible for study inclusion, eight symptoms from the study protocol are evaluated and registered in the Prehospital Patient Journal (PPJ) on the amPHITM Prehospital Health Care Record (Amphi Systems, Hasserisvej 125, 9000 Aalborg, Denmark), on a tablet mounted in each EMT vehicle. If the vehicle is in the control arm the patient is triaged by the on-call neurologist based on a standard telephone call

Group Type NO_INTERVENTION

No interventions assigned to this group

Video call assisted assessment of acute stroke

If the patient is eligible for study inclusion, the last symptoms from the study protocol are evaluated and registered in the Prehospital Patient Journal (PPJ) on the amPHITM Prehospital Health Care Record (Amphi Systems, Hasserisvej 125, 9000 Aalborg, Denmark), on a tablet mounted in each EMT vehicle. Afterwards the EMS personnel will contact the on-call neurologist and if the vehicle is in the intervention arm a live video stream is initiated. The on-call neurologist then examines the patient via the video-call and triage the patient.
