Selective Smartphone Alerts Helped Improve Bystander Response Time for Cardiac Arrest

Research Highlights: Selecting which volunteer community first responders were alerted to the scene of a cardiac arrest was overall more successful when alerting responders who had shorter estimated arrival times than only sending out alerts to responders who were geographically closer to the scene and also reduced dispatching volunteers likely to get to the scene after EMS, according to preliminary research conducted by researchers in Freiburg, Germany. Because “smart” alerting considered obstacles related to how fast the responder could get to the scene, this method nearly doubled the chance of early volunteer arrival compared with alerts sent only to responders within the nearby geographical area. The researchers said further studies are needed to determine whether smart alerting improves cardiac arrest survival. Note: This trial is simultaneously published today as a full manuscript in the peer-reviewed scientific journal, Journal of the American Heart Association .
