Brief Summary:
The main aim of the study is to show that patients with suspected acute stroke met by the emergency medical service and assessed using the eSTROKE model including prehospital NIHSS and a mobile application will identify a higher number of patients with stroke, than those who receive conventional prehospital care.

Condition or disease Intervention/treatment Phase
Stroke Triage Paramedic Mobile Application Diagnostic Test: eSTROKE model Other: Control Not Applicable

Detailed Description:

Primary aims:

In patients with suspected stroke

  1. The proportion of patients hospitalized with a suspected acute stroke and discharged with a stroke diagnose is significantly increased using the ParaNASPP model compared with conventional prehospital care
  2. Time from onset to hospitalization is significantly reduced with the ParaNASPP model
  3. The ParaNASPP model identifies patients eligible for direct transportation for comprehensive stroke center
