Association of National Initiatives to Improve Cardiac Arrest Management With Rates of Bystander Intervention and Patient Survival After Out-of-Hospital Cardiac Arrest

Study Questions:

Out-of-hospital cardiac arrest is a major health problem and it is linked to poor outcomes. Because early recognition and intervention are critical for better outcomes, improving bystander resuscitation attempts may improve survival. Have temporal changes in bystander resuscitation attempts and survival occurred over a 10-year period during which several national initiatives were undertaken to increase bystander resuscitation attempts and improve advanced care?
