Intervention sites
For all 1-1-2 calls with suspected cardiac arrest to the emergency dispatch center will activate a two-tiered response consisting of dispatch of an ambulance with an emergency medical technician, a physician-staffed mobile emergency care unit, and citizen first responders through the Heart Runner app. The medical dispatcher offers telephone assisted cardiopulmonary resuscitation (CPR) to bystanders. Furthermore, if more than two bystanders are present and an AED is accessible within 1½ minute travel distance (depending on the type of terrain), then one bystander is guided to localize and retrieve the AED.
As a supplement to the standard care as described in the control arm, the following will be supplied: Strategical deployment of AEDs with 24:7 availability and 1½ minute walking distance to every residence within the area. The AEDs will be registered with the AED network and thus linked to the emergency dispatch center. The emergency dispatch center will retrieve data from used AEDs. For each interventional area, approximately 120 residents will receive a course in CPR and AED use and subsequently be recruited as citizen responders so that they can be activated through the HeartRunner app in case of a nearby cardiac arrest.
