Abstract

This 57-month study evaluated the use of automatic external defibrillators (AEDs) in the homes of high risk cardiac patients (survivors of out-of-hospital ventricular fibrillation [VF]). The goal was to determine the utility of these devices by trained lay persons in actual cardiac arrest episodes. Ninety-seven survivors of out-of-hospital VF were enrolled in the study; 59 patients received AEDs, and 38 patients served as a control group. During the study period, 7 deaths occurred in the hospital without preceding out-of-hospital cardiac arrest or from noncardiac causes. There were 14 out-of-hospital cardiac arrests, 10 in the AED group and 4 in the control group. There was 1 long-term survivor in the control group. In the AED group, among the 10 cardiac arrests for which the device was available, it was used in 6. Only 2 patients were in VF; 1 was resuscitated with residual neurologic deficits and survived several months. This study observed a small potential for AEDs to save high risk patients.

    These studies used varying methods for CPR training and assessment of outcomes. In brief, there is insufficient evidence on patient outcomes to support or refute the use of training interventions in high-risk groups.60–70 Existing evidence on educational outcomes suggest likely rescuers are willing to be trained,63,71–77 are likely to share training with others,71,74,75,78–80 are unlikely to seek training on their own,63,79 and, after training, are competent in BLS skills and/or knowledge.33,71,73,74,78,81–90

    Nevertheless, other studies in suburban and rural areas have indicated higher rates of survival, up to 35% [14]. The placement of automatic external defibrillators in communities along with a major focus on training the personnel about their use has the potential to markedly improve the outcomes [14–21]. SCD often represents the first expression of cardiac disease in several individuals presenting with out-of-hospital cardiac arrest and most cases occur in patients with structural abnormalities of the heart.
