![]() ![]() Prehospital data were the date, location, and etiology of OHCA the type of first responder and whether the patient received bystander CPR or prehospital treatment from an automated external defibrillator (AED). We collected the following demographic information about the patients: sex, age, and medical history. ![]() 6, 25, 26 Our aim in this study was to use data from the Korea OHCA Registry (KOHCAR) to assess the most recent trends in the epidemiology and survival outcomes of pediatric OHCA patients and to analyze the factors that influence survival outcomes. 12, 14 In addition, the delivery of pre-hospital emergency care differs from country to country, so research using regional data is needed. New policies are based on epidemiology research, so it is necessary to analyze recent trends and identify variables that affect survival outcomes. Understanding the characteristics and patterns of OHCA in each age group is critical for designing long-term national prevention measures, age-specific resuscitation care strategies, and pediatric OHCA training programs. 21, 22, 23, 24 As a result, the mechanism of OHCA and survival outcomes also vary significantly with age. 17, 18, 19, 20 Children’s growth and development vary significantly with age. 16 Some studies have reported age-related variations in the mechanisms of OHCA and survival outcomes. 3, 14, 15Įpidemiological analyses of OHCA have allowed researchers to find vulnerabilities in the chain of survival and to improve survival outcomes during the past few decades. 12, 13 Due to those efforts, the survival outcomes of adult OHCA patients in the Republic of Korea have improved, but the survival rate of pediatric OHCA patients has not changed significantly. In the Republic of Korea, the government has endeavored to improve the chain of survival through the National OHCA registry, regular public reports, a mandatory CPR training program, a telephone-assisted CPR program, and medical oversight for emergency medical service (EMS) CPR performance since 2008. 7, 8, 9, 10 Nevertheless, the survival outcomes of pediatric OHCA patients need to be improved because of children’s long potential life expectancy, even a few deaths from pediatric cardiac arrest cause significant social and economic losses. 2, 3, 4, 5, 6, 7 The relatively small number of cases and poor survival outcomes cast doubt on the value of pediatric cardiopulmonary resuscitation (CPR). 1 The incidence of pediatric out-of-hospital cardiac arrest (OHCA) is 1–20 per 100,000 person-years, and the survival rate and neurologic outcomes of pediatric OHCA are poor, with regional variation. Unexpected cardiac arrest is a major health problem worldwide. ![]()
