Improving survival from out-of-hospital cardiac arrest (OHCA) is an important but difficult public health challenge. Each minute of delay in treatment reduces chance of survival drastically. Before EMS arrives, bystanders can help the patient by performing chest compressions or by connecting an automated external defibrillator (AED) to give a shock. To improve this process, citizen responder systems have been implemented in many countries to dispatch and guide nearby registered volunteers towards the location of the patient or an AED. In this presentation, we give an overview of our research on where to place AEDs in such a system, based on actual cardiac arrest data. We visualize spatial and spatiotemporal incidence of OHCA, and identify areas with significantly higher or lower mortality. We show AED location models based on covering models, but include different coverage functions for different types of volunteers. Additionally, we show preliminary results of our model that maximizes estimated health outcomes instead of coverage. This allows us to evaluate cost-effectiveness of purchasing additional AEDs positioned at the right places.
