Summary

The aim of this study is to provide detailed information on state of mind, psychological wellbeing and stress for lay responders dispatched to suspected OHCA via a mobile phone application. The Heartunner system is a mobile phone positioning system for dispatch of CPR-trained lay volunteers to nearby suspected out-of-hospital cardiac arrests (OHCAs). After downloading of a mobile phone application (The Heartrunner application), and given consent of participation, the lay responders are dispatched to nearby suspected OHCA. The lay responders are either dispatched directly to the scene of the suspected OHCA to perform CPR, or to fetch the nearest AED. The location of the OHCA and available AEDs are displayed on a map, facilitated by the Heartrunner application. The Heartrunner system is studied through "The SAMBA-trial" on clinical outcomes for OHCA patients (ClinicalTrials.gov Identifier: NCT02992873). The psychological effects among the lay responders will be evaluated with an online survey adjacent to dispatch and after 4-6 weeks. The results of the survey will be compared both intra-individual, and to a control group of not dispatched lay responders within the Heartrunner system. Descriptive statistics regarding interventions, age, gender and former experience will also be presented.
