ObjectivesTo comprehensively describe the incidence, process of care, outcomes, and variation among different age groups of pediatric out-of-hospital cardiac arrest (OHCA) in China.DesignThe Baseline Investigation of Out-of-Hospital Cardiac Arrest (BASIC-OHCA) is a prospective, multicenter, population-based registry of emergency medical services (EMS)-assessed OHCA in China.SettingA total of 25 monitoring sites of all seven geographical regions were included, covering a pediatric population (age ≤ 19) of around 22.3 million in China.PatientsPediatric patients enrolled in BASIC-OHCA from August 2019 to December 2020 were included.InterventionsNone.Measurements And Main ResultsA total of 1493 pediatric patients with EMS-assessed OHCA were enrolled, and resuscitation was attempted in 651 cases (43.6%). The crude incidence of EMS-assessed and EMS-treated OHCA was 5.5 (95% CI, 5.2-5.9) and 2.4 (95% CI, 2.2-2.6) per 100,000 pediatric population. Among 651 EMS-treated OHCA cases, 434 patients (66.7%) were male, and 353 (54.2%) had nonmedical causes (trauma, asphyxia, and drowning being the most common). There were 396 patients (60.8%) who collapsed at home, and the proportion of cases that occurred in public places such as streets and schools increased with age. There were 26 patients (4.0%) who had an initial shockable rhythm. For 626 non-EMS-witnessed patients, 152 patients (24.3%) received bystander cardiopulmonary resuscitation (CPR), 68 (10.9%) received dispatcher-assisted CPR, and 3 (0.5%) had automated external defibrillator applied. The survival to discharge or 30 days was 3.5% (23/651), and the favorable neurologic prognosis was 3.1% (20/651), with no differences among age groups.ConclusionsThis study provides the first national exploration of pediatric OHCA in China. The high proportion of nonmedical causes underscores the importance of preventing accidents in children. Gaps in the chain of survival and patient outcomes provide a focus for improving the treatment of pediatric OHCA in China and other developing countries.Copyright © 2024 by the Society of Critical Care Medicine and Wolters Kluwer Health, Inc.
