Penn CRS members have developed a crowd sourcing, social media, mobile media fun contest to find AEDs (automated external defibrillator) and raise awareness.

This project is a community improvement initiative and part of a research study being conducted at the University of Pennsylvania. Join this initiative for a chance to win monetary prizes and to help save lives! Visit our website today at www.myheartmap.org.

Description of Research Expertise

Dr. Merchant's research is focused on resuscitation science and improving outcomes from cardiac arrest. Specifically she studies 1) diffusion of innovation and new media in resuscitation and 2) translation of research to policy.

In the in-patient setting, she is studying best practices for improving in-hospital cardiac arrest care. In the pre-hospital setting-she is identifying communities at risk for cardiac arrest and evaluating unique strategies for optimizing cardiopulmonary resuscitation (CPR) training and automated external defibrillator AED availability. In this context, she is the Director of the MyHeartMap Challenge- a social media, mobile media, and crowd sourcing project aimed at improving AED access and awareness.

Keywords: social media, crowd sourcing, public health, health services research, cardiovascular outcomes, AEDs, health policy
