  • Out-of-hospital cardiac arrest (OHCA) remains a major public health challenge; approximately 356,500 people are treated for OHCA annually in the US.
  • Advancements in 9-1-1 telephone CPR instructions, bystander CPR, CPR techniques, public AED availability, and post resuscitation care have been shown to improve outcomes, but implementation varies regionally and there are opportunities for improvement.
  • Cardiac arrest centers and the regionalization of cardiac care have shown promise, but work remains to be done to further understand regional variation and optimize OHCA patient care.
