目的:基于ISS评估急诊科多发创伤患者滞留时间的临床影响因素，并分析滞留时间与患者病死率的相关性。方法:选取2013年10月至2016年11月经我院急诊科收治的多发创伤患者244例，评估、记录患者ISS评分，统计患者的一般资料、急诊滞留时间及此次就诊的转归。结果:研究显示，涉及患者244例，男性191例、女性53例，急诊滞留时间（117.25±87.442）min，数据显示临床转归为死亡的人数46例。结论：:多发性创伤患者ISS分值越高在急诊科的滞留时间相对越长，急诊滞留时间延长的患者病死率相对较高，多发性创伤ISS分值更高则病死率更高。“,”Objective:The clinical influencing factors of residence time of patients with multiple trauma in emergency department were evaluated based on ISS, and the correlation between emergency department length of stay and mortality was analyzed.Methods:From October 2013 to November 2016244patients with multiple trauma treated in the emergency department of our hospital were selected to evaluate and record the ISS score of the patients, and to count the general data of the patients, the emergency department length of stay and the outcome of this visit.Results:The study showed that 244 patients were involved, 191 males and 53 females. The emergency emergency department length of stay was (117.25±87.442) min, The data show that 46 cases were clinically converted to death.Conclusions:The higher the ISS score of multiple trauma patients, the longer the emergency department length of stay, the higher the mortality rate of patients with prolonged emergency department length of stay, and the higher the ISS score of multiple trauma patients, the higher the mortality rate.
