Acute cardiac care & resuscitation
Epidemiology of pediatric out-of-hospital cardiac arrest compared with adults
Authors' conclusion
In contrast to young adults with OHCA, the most common etiology was noncardiac in pediatric patients. Prognostic factors associated with survival to discharge included increasing age, witnessed arrest, and initial ventricular arrhythmias.
Study context
- Population
- Children aged 1–18 years with out-of-hospital cardiac arrest (OHCA), Victoria, Australia, April 2019 to April 2021cases after adjudication
- Participants
- 106 children
- Outcome
- Survival to hospital discharge
Methodological detailsstatewide, multisource registry
- Statewide
- Multisource registry
Main finding
As reported in the abstract
- Cardiac causes of OHCA
- 45 (42.5%)
- Unascertained (most common cardiac cause)
- n = 33 [31.1%]
- Respiratory events (most common noncardiac cause)
- n = 28 [26.4%]
- Overall survival to hospital discharge
- 11.3%
- Survival associated with increasing age, witnessed arrest and initial ventricular arrhythmias
- P < .05
- Incidence of pediatric OHCA (pOHCA)
- 3.69 per 100,000 child-years
Observational data: associations, not effects.
Further findings
Initial rhythm by cause
- Noncardiac causes more likely to present with asystole or pulseless electrical activity
- P = 0.007
Sex
- Male
- 62, 58.5%
