한국의 예방 가능 외상 사망률과 외상 처치 체계의 변화

초록

Purpose: This study was performed in order to determine the changes over time in preventable and potentially preventable traumatic death rates, and to assess the factors that affected the deaths of trauma patients which occurred in Korean pre-hospital and hospital settings. Methods: All trauma deaths occurring either in the emergency department (ED) or after admission at twenty Korean hospitals between August 2009 and July 2010 were retrospectively analyzed. The deaths were initially reviewed by a team of multidisciplinary specialists and classified into nonpreventable,potentially preventable, and preventable deaths. Only preventable and potentially preventable deaths were the subject of our analysis. Structured data extraction included patient demographics, vital signs, injury severity, probability of survival, preventability of mortality,reported errors in the evaluation and management of the patient, and classification of error types (system, judgment,knowledge). Results: During the study period, 446 trauma victims died in the ED or within 7 days after admission. The mean age was 52 years, 74.1% were men and the mean time from injury to death was 35.6 hours. The most common cause of death was head injury (44.7%) followed by hemorrhage (30.8%) and multi-organ failure (8.0%). The rates of preventable/potentially preventable deaths were 35.2% overall and 29.8% when limited to patients surviving to admission. Of all death classifications, 31.2% were potentially preventable and 4.0% were preventable. Errors leading to preventable death occurred in the emergency department (51.2%), pre-hospital setting (30.3%) and during inter-hospital transfer (60.8%). Most errors were related to clinical management (48.4%) and structural problems in the emergency medical system (36.5%). Conclusion: The preventable death rates for Korean trauma victims were higher than those found in other developed countries, possibly due to poorly established emergency medical systems for trauma victims in pre-hospital and hospital settings. A system wide approach based on the emergency medical system and well-developed in-hospital trauma teams should be adopted in order to improve the quality of care of trauma victims in Korea.
