병원전 노인 심정지 환자의 역학적 특성과 생존 결과

초록

Despite continuous improvements of the emergency medical service system, aging of population has an adverse impact on survival outcomes. This study was a cross-sectional study utilizing prehospital care report data in 2017, and we compared the epidemiological trends in cardiac arrest incidence and survival between the ≥65 years out-of-hospital cardiac arrest group and <65 years group. The proportion of male older adults was relatively high (61.4%) as well as the proportion of elderly for whom defibrillation was not performed (85.0%) in traumatic elderly. There were statistically significant differences in these factors (p=.001; <.001). The increasing curve of prevalence of out-of-hospital cardiac arrest and decreasing curve of survival to admission with advancing age crossed in the 55-64 years group. The incidence of cardiac arrest increased while survival decreased, reaching survival turning point. The incidence of out-of-hospital cardiac arrest was very high, however survival to admission was low among the elderly. Significant number of the older adults who had out-of-hospital cardiac arrest were male, and a defibrillation could not be performed for a high percentage of these elderly cardiac arrest patients.
