摘　　要：目的探讨急诊患者死亡的危险因素,为提高急诊患者分诊效率提供临床依据。方法回顾性分析2009年1—12月北京协和医院急诊科挂号并静脉输液的22 161例患者的临床资料,包括年龄、性别、生命体征、意识水平、主诉,计算休克指数(SI),并进行多元回归分析。结果与急诊患者病死率相关的危险因素按相关强度顺序包括:血氧饱和度<92%、意识改变、呼吸窘迫、胸痛、心率>120次/min,收缩压<90 mm Hg,创伤与出血、年龄>65岁、男性、舒张压<60 mm Hg。SI和急诊患者的病死率无显著相关性。结论急诊分诊需要重视的危险因素包括:生命体征异常、意识改变、胸痛、创伤与出血及高龄或男性。Objective The objective of this study is to analyze mortality risk factors of emergency department patients in order to provide evidence to further increase the efficiency of triaging.Methods Retrospective chart review of 22,161 patients who presented to Peking Union Medical College Hospital Emergency Department and received IV fluids from January 1st,2009 to December 31st,2009.Multivariable regression analysis of age,gender,vital signs,level of consciousness,presenting complaint,calculated shock index and outcome was performed.Results Emergency patients′ risk factors for mortality in order of decreasing relevance are：oxygen saturation 92%,altered mental status,dyspnea,chest pain,heart rate 120 beats per minute,systolic blood pressure 90 mm Hg,trauma and hemorrhage,age 65 years,male gender,diastolic blood pressure 60 mm Hg.Shock index and mortality rate have no significant correlation for emergency patients.Conclusion The important points to consider in triage are：abnormal vital signs,altered mental status,chest pain,trauma and hemorrhage,elderly and male gender.
