초록
이 연구는 서울시 55개 재난 유형 중 하나인 심정지 사고의 황금시간을 검증하였다. 소방재난본부의구급데이터 자료(기간: 2010~2012년) 4,055건을 분석에 활용하였으며 ‘구급대원이 출동하여 심폐소생술을 해야 하는 시간 4분 이내’의 효과성을 검증하였다. 분석방법은 출동시간 구간별 회귀분석을 실시하였으며, 무상관추정(SUEST: seemingly unrelated estimation)을 통한 사후 검증을 실시하였다. 분석결과, 구급대원의 도착시간은 평균 5.7분으로 확인되었으며 출동시간은 점차 개선되고 있는 것으로 나타났다. 그리고 출동시간 별 구간을 8개로 구분하여 구급효과성과의 관계를 분석한 결과 ‘4분 이내’가 심정지의 황금시간으로 적절하다는 것이 입증되었다. 이 연구는 심정지의 황금시간 4분을 통계적으로 확정하려는 시도를 최초로 하였다는 점에서 구조⋅구급과 관련된 연구 분야에큰 의미를 가진다.
Abstract
This study verified the “golden time” in cardiac arrests, one of the 55 disaster types identified by Seoul. 4,055 cases from the rescue and EMS data maintained by Seoul Metropolitan Fire & Disaster Headquarters (2010~2012) were used to verify the effectiveness of CPR performed by paramedics within 4 minutes. A regression analysis was conducted for each of the 8 response time sections and the post-verification was carried out through SUEST (Seemingly Unrelated Estimation). The average arrival time was found to be 5.7 minutes and the response time appeared to improve gradually. The analysis of the relationship between response time and the effectiveness of first aid showed that “within 4 minutes” is the most appropriate golden time for treatment of cardiac arrests. This study has great implications for the field of rescue and EMS as it made the first attempt to confirm a statistical significance of “within 4 minutes” as the golden time in cardiac arrests.
