“…The AED self-instruction card showed impressive ability as a readily available tool to help first-time users to operate AED with better effectiveness. As previous studies have indicated, failure to bare the chest, [16,17] incorrect electrodes placement, [18,19] failure to defibrillate the patient, [20] and lack of awareness to resume CPR after shock, [16,21] were the most common errors in the public usage of AEDs. Thus, the card was designed to emphasize the key points of each step, which proved to be more effective than commercialized AEDs instruction manuals.…”

BACKGROUND: To evaluate whether a simplified self-instruction card can help potential rescue providers use automated external defibrillators (AEDs) more accurately and quickly. METHODS:From June 1, 2018, to November 30, 2019, a prospective longitudinal randomized controlled simulation study was conducted among 165 laypeople (18-65 years old) without prior AED training. A self-instruction card was designed to illuminate key AED operation procedures. Subjects were randomly divided into the card (n=83) and control (n=82) groups with age stratification. They were then individually evaluated in the same simulated scenario to use AED with (card group) or without the self-instruction card (control group) at baseline, posttraining, and at the 3-month follow-up. RESULTS:At baseline, the card group reached a significantly higher proportion of successful defibrillation (31.1% vs. 15.9%, P=0.03), fully baring the chest (88.9% vs. 63.4%, P<0.001), correct electrode placement (32.5% vs. 17.1%, P=0.03), and resuming cardiopulmonary resuscitation (CPR) (72.3% vs. 9.8%, P<0.001). At post-training and follow-up, there were no significant differences in key behaviors, except for resuming CPR. Time to shock and time to resume CPR were shorter in the card group, while time to power-on AED was not different in each phase of tests. In the 55-65 years group, the card group achieved more skill improvements over the control group compared to the other age groups. CONCLUSION:The self-instruction card could serve as a direction for first-time AED users and as a reminder for trained subjects. This could be a practical, cost-effective way to improve the AED skills of potential rescue providers among different age groups, including seniors.

“…In accordance with previous studies, incorrect pad placement mostly occurred on the left side. [25,26] The left electrode was more likely to be attached medially and lower than the recommended position. This could be due to laypeople's inability to understand the diagrams.…”

BACKGROUND: Automated external defibrillators (AEDs) enable laypeople to provide early defi brillations to patients undergoing cardiac arrest, but scant information is available on the general public's ability to use AEDs. This study assessed the ability of laypeople to operate AEDs, the effect of a 15-minute training, and whether skills differed by age. METHODS: From May 1 to December 31, 2018, a prospective simulation study was conducted with 94 laypeople aged 18-65 years (32 aged 18-24 years, 34 aged 25-54 years, and 28 aged 55-65 years) with no prior AED training. The participants' AED skills were assessed individually pretraining, post-training, and at a three-month follow-up using a simulated cardiac arrest scenario. The critical actions and time intervals were evaluated during the AED operating process. RESULTS: Only 14 (14.9%) participants (eight aged 18-24 years, four aged 25-54 years, and two aged 55-65 years) successfully delivered defi brillations before training. AED operation errors were more likely to occur among the participants aged 55-65 years than among other age groups. After training, the proportion of successful defi brillations increased signifi cantly (18-24 years old: 25.0% vs. 71.9%, P<0.01; 25-54 years old: 11.8% vs. 70.6%, P<0.01; 55-65 years old: 7.1% vs. 67.9%, P<0.01). After three months, 26.1% of the participants aged 55-65 years successfully delivered defi brillations, which was signifi cantly lower than that of participants aged 18-24 years (54.8%) and 25-54 years (64.3%) (P=0.02). There were no differences in time measures among three age groups in each test. CONCLUSIONS: The majority of untrained laypeople cannot effectively operate AEDs. More frequent training and refresher courses are crucial to improve AED skills.
