Infographic: Effectiveness of Dual Dispatch to Cardiac Arrest Policy

The policy in Houston, Texas, is to dual dispatch medically trained firefighters in addition to emergency medical services (EMS) units to out-of-hospital cardiac arrest (OHCA) cases. While believed to improve public health outcomes, no research exists to support the policy that when firefighters respond before a better-equipped EMS unit, they increase the probability of survival. This retrospective study by Dr. Loren Raun et al uses logistic regression to determine the association between return of spontaneous circulation (ROSC) and response time for fire apparatus first responders controlling for arrival of the EMS unit. Read more about the results of this article, “Effectiveness of the Dual Dispatch to Cardiac Arrest Policy in Houston, Texas,” published ahead of print in the Journal of Public Health Management and Practice.
