Hospital-based metrics
 Hypothermia induced after initial VT/VF, %66.3 (62.3–70.3)66.2 (62.1–70.2)100 (100–100)
 No order for withdrawal/DNR during first 72 h, %§45.0 (42.1–48.0)44.8 (41.9–47.8)100 (100–100)
 Implantable cardioverter-defibrillator assessment, initial VT/VF, no AMI per MD notes or final ECG interpretation, %30.3 (24.8–35.8)30.0 (24.5–35.6)100 (100-100)
  • Values are mean (95% confidence interval) or mean (SD). Because age is missing for some cases, these cases are not included in either adults or children, thus explaining why overall rates equal the adult rates when rates for children are not available. AED indicates automated external defibrillator; AMI, acute myocardial infarction; CPR, cardiopulmonary resuscitation; DNR, do not resuscitate; ECG, electrocardiogram; EMS, emergency medical services; MD, medical doctor; ROC, Resuscitation Outcomes Consortium; SD, standard deviation; and VT/VF, ventricular tachycardia/ventricular fibrillation.

  • * Data are from EMS-treated cases.

  • During 2014, there was 1 pediatric case with initial rhythm VT/VF admitted to the hospital.

  • Denominator is all cases with initial rhythm VT/VF and admitted to the hospital.

  • § Denominator is all cases admitted to the hospital.

  • Denominator is all cases with initial rhythm VT/VF, no indication of AMI, no percutaneous coronary intervention, no bypass, and admitted to the hospital.
