Here are six Sudden Cardiac Arrest (SCA) statistics that every facility manager should know:1) Out-of-Hospital SCA Incidents
According to an article published this year (2018) by the Sudden Cardiac Arrest Foundation, "There are more than 356,000 out-of-hospital cardiac arrests (OHCA) annually in the U.S.
2) Fatality Rates of Out of Hospital SCA
This report quotes the American Heart Association as saying that nearly 90% of SCAs are fatal with 10.8 of the victims surviving to hospital discharge with only 9% with good neurological function.
3) Percentage of Sudden Cardiac Arrests (SCA) That Occurred in Outside Facilities
This report goes on to say that 21% of the out-of-hospital cardiac arrests (OHCAs) occur in public settings while 68.5% occurred at home or residence and 10.5% at nursing homes.
4) Survival Rate with Use of AED
An international team of researchers looked at 49,555 out-of-hospital cardiac arrests that occurred in major cities of the United States and Canada. They analyzed a key subgroup of these arrests, those that (a) occurred in public, (b) were witnessed and (c) were shockable. The researchers found that 66.5 percent of these victims survived to hospital discharge after a shock delivered by a bystander compared to 43% when the shock was delayed for EMS application.
5) Survival rate with AED and CPR
Combining bystander AED use with proper CPR techniques have been shown to improve the likelihood of a successful resuscitation effort. A published presentation, Analysis of bystander CPR quality during out-of-hospital cardiac arrest using data derived from automated external defibrillators, in Ottowa, ON, evaluated bystander CPR quality during OHCA. Utilizing data stored within Automated External Defibrillators (AEDs), and matched with cases enrolled in the Resuscitation Outcomes Consortium (ROC) database, they found that bystanders demonstrated high-quality CPR over the course of resuscitation with good adherence to published resuscitation guidelines resulting in a survival rate of 42.0%.
6) Failure Rates for AED Devices
There is a common concern that life-saving AEDs may fail at the time they are most needed.
This article on the sca-aware.org site addresses a study done by LA DeLuca Jr., et al, published in the Annals of Emergency Medicine in 2012. It notes that while the DeLuca study did find that 1150 AED failures occurred between June 1993 and October 2008, this was in relation to 40,787 AED related instances for a failure rate of 2.8%. Conversely, this means that the AEDs functioned properly over 97% of the time.
In addition to noting that AED failures are remarkably rare, the article goes on to state, Most “AED failures” can be prevented through planning and implementation of effective maintenance programs developed under medical direction.
Having an AED Program Management Tool in Place Saves Lives
As facility managers, you should be aware of these six sudden cardiac arrest statistics and be prepared to relate them to your own facility. In addition, you may want to take the additional step of partnering with PlusTrac™, "The World's Leading AED Program Management Solution" to make sure your AEDs are prepared to render their life-saving shocks when needed.
Knowledge and performance of quality cardiopulmonary resuscitation (CPR) by bystanders and the effective use of an automated external defibrillator (AED), prior to the arrival of paramedics, can significantly improve the odds of survival.
