Identifying Locations for Public Access Defibrillators Using Mathematical Optimization

Identifying locations for public access defibrillators using mathematical optimization.

BACKGROUND Geospatial methods using mathematical optimization to identify clusters of cardiac arrests and prioritize public locations for defibrillator deployment have not been studied. Our objective was to develop such a method and test its performance against a population-guided approach. METHODS AND RESULTS All public location cardiac arrests in Toronto, Ontario, Canada, from December 16, ...

Optimizing the Deployment of Public Access Defibrillators

Public locations of cardiac arrest. Implications for public access defibrillation.

BACKGROUND The purpose of this study was to describe the public locations of cardiac arrest and to estimate the annual incidence of cardiac arrest per site to determine optimal placement of automatic external defibrillators (AEDs). This was a retrospective cohort study. METHODS AND RESULTS Locations of cardiac arrest were abstracted from data collected by emergency medical service programs in...

Time to Shock vs. Voice Prompt Duration: Optimization of Defibrillators for Public Access and Home Deployment

The time interval from onset of ventricular fibrillation (VF) to successful defibrillation shock has been identified as a primary correlate to survival. Widespread deployment of automated external defibrillators (AEDs) for public access defibrillation (PAD) and home use offers the potential of reducing this interval by minutes. Unfortunately, studies have reported that a significant percentage ...

Defibrillators in public places: the introduction of a national scheme for public access defibrillation in England.

OBJECTIVE To implement a government-led project-the 'Defibrillators in Public Places' Initiative-to deploy Automated External Defibrillators (AEDs) in public places. BACKGROUND A Defibrillator Advisory Committee (DAC) was formed to assist the government with the implementation of the project. Its particular tasks were to: recommend criteria for the selection, training and assessment of those ...
