About this study
A study to investigate how stroke is identified and whether FAST, face-arm-speech test, is used in the emergency medical dispatch centre in Stockholm. The study will also investigate when FAST is used, does it increase the identification of stroke? And if other factors can be identified as "markers" for more effective identification of stroke during the emergency call.
Read the detailed description
Transcribed alarm calls are read through and analyzed using a qualitative method. Meaningful units are identified, coded and categorized. A phenomenological analysis is also applied to a separate analysis.

What is being measured
The primary outcome is the main question the study is designed to answer.
Frequency of stroke symptoms
A data collection tool assessing the frequency of stroke symptoms will be developed. The data collection tool will identify stroke symptoms presented by the caller during emergency calls and assess stroke symptoms in the Face-Arm-Speech-Time Test (FAST). Stroke symptoms will then be quantified into percentages for a descriptive analysis.
Measured: 1 h
