Use of a Wearable Automated Defibrillator in Children Compared to Young Adults
Key result
Wearable defibrillators deliver no appropriate shocks in children compared to ~2% of young adults.
- n=184
Why the study?
Does the compliance and safety of a wearable automated external defibrillator differ between pediatric patients (≤18 years) and young adults (19-21 years)?
Population
184 patients from a clinical database, including 81 pediatric patients and 103 young adults.

Implication
No appropriate shocks in children warrant caution against routine pediatric use; leaves open wearable AED efficacy and supports prospective trials.

Type
Cohort (n=184)
Structured PICO
Does the compliance and safety of a wearable automated external defibrillator differ between pediatric patients (≤18 years) and young adults (19-21 years)?
P
Population
184 pediatric and young adult patients (aged 9-21 years) at high risk of sudden cardiac arrest using a wearable automated external defibrillator, retrospectively reviewed.
E
Exposure
Wearable automated external defibrillator in pediatric patients (≤18 years of age)
C
Comparator
Wearable automated external defibrillator in young adults (aged 19-21 years)
O
Outcome
Device compliance (average hours/day and total number of days worn) and device therapies (appropriate and inappropriate discharges)safety
Main Result
Absolute Event Rate: 0% vs 1.9%
The wearable automated external defibrillator demonstrates similar compliance in pediatric patients compared to young adults, though its efficacy in preventing sudden cardiac arrest in children remains unproven due to a lack of appropriate shocks in this cohort.
Limitations
- As there were no appropriate shocks in patients ≤18 years of age, this study cannot address efficacy of the therapy.
- No appropriate shocks in patients ≤18 years of age, preventing assessment of efficacy
Cite This Study
Collins et al. (2010) conducted a cohort in High risk of sudden cardiac arrest (n=184). Wearable automated external defibrillator in patients ≤18 years vs. Patients aged 19-21 years was evaluated on Patients with appropriate discharges. The wearable automated external defibrillator delivered no appropriate shocks in children ≤18 years (0%), compared to appropriate discharges in 1.9% of young adults aged 19-21 years.
