Tele-Stroke: Prehospital Identification of Patients With Suspected Stroke Using Onsite Mobile Telemedicine - Feasibility

Completed

• Conditions: Stroke, Acute
• Interventions: Diagnostic Test: Audio-video-streaming of suspected stroke symptoms and signs

• Registration Number: NCT03370094
• Lead Sponsor: University Hospital, Basel, Switzerland

Brief Summary

Observational Study to investigate the technical feasibility, implementation into current diagnostic and treatment pathways and the diagnostic accuracy of the remote patient assessment by using mobile telecommunication ahead of hospitalization.

Detailed Description

On-site, pre-hospital clinical assessment of patients with suspected acute stroke can accelerate further diagnostic and treatment pathways after patient arrival at the emergency room or the dedicated stroke center. Interactive video and audio streaming connecting on-site paramedics to a stroke center based stroke physicians can help to overcome these hurdles. Patient evaluation by simple, pre-defined assessment measures and a standardized questionnaire may enable a pre-hospital decision on the need of expedited diagnostic and treatment procedures after arrival at the dedicated stroke center.

Arm && Interventions

Group	Intervention	Description
patients with suspected stroke	Audio-video-streaming of suspected stroke symptoms and signs	patients with suspected stroke due to paramedic's initial evaluation of face, arm, and speech function will be diagnosed with audio-video-streaming of suspected stroke symptoms and signs

Primary Outcome Measures

Name	Time	Method
Diagnostic accuracy of the patient evaluation by remote Audio/video session	1 hour	The proportion of successfully realized 'telestroke' interviews (=patient has a stroke yes/no) in comparison to final diagnosis by the caring stroke team.

Secondary Outcome Measures

Name	Time	Method
Diagnostic accuracy of an automated biometric software	12 months	The proportion of correct stroke diagnosis by the automatic biometric assessment compared to the final diagnosis of the caring stroke team.
