Future Directions: Management of Sudden Cardiac Death.

There will always be a need to optimize early recognition and treatment of sudden cardiac arrest. For out-of-hospital cardiac arrest, this requires a complex system of care involving bystanders, 911 dispatchers, and emergency medical service and hospital-based providers. Optimizing this system is fundamental to improving outcomes. In addition, personnel and resources are needed to develop and sustain a research pipeline that will bring new scientific discoveries and technologies to the field. The 2015 Institute of Medicine report, "Strategies to Improve Cardiac Arrest Survival: A Time to Act," provides a roadmap.
