About the National Data
Baseline: 9.0 percent of bystanders used an AED for non-traumatic cardiac arrests occurring in public locations in 2020
Target: 12.0 percent
CARES case: A non-traumatic out-of-hospital cardiac arrest event where resuscitation is attempted by a 911 responder (CPR and/or defibrillation). This includes patients that received an automated external defibrillator (AED) shock by a bystander prior to the arrival of 911 responders.
Active bystander AED intervention: Automated external defibrillator application to the patient by a lay person with a minimum of one analysis of the patient's heart rhythm performed, regardless of whether or not a shock is indicated. It excludes patients that go into cardiac arrest after the arrival of a 911 provider since this would not be a situation that a bystander would be able to intervene. It also does not include patients that experience their cardiac arrest in a nursing home or medical facility where trained providers would be able to apply an AED or monitor/defibrillator.
Public locations: All defined CARES location types with the exception of Home/Residence; Healthcare Facility/Hospital; Nursing Home; and Jail to include Public/Commercial Building; Street/Highway; Place of Recreation; Industrial Place; Transport Center; Other.
Numerator and denominator exclude 911 witnessed events.
In 2021, this objective was revised due to the creation of a new cohort by the data source, CARES. The baseline was revised from 11.4% in 2017 to 9.0% in 2020. The target was revised from 14.8% to 12.0% using the original target setting method.
1. Effect size h=0.1 was chosen to correspond with 10% improvement from a baseline of 50%.
