急诊室危重患者滞留时间影响因素Logistic回归分析

摘要

Objective To explore factors associated with emergency room(ER)length of stay and provide basis for the emergency managers about the development of relevant measures.Methods Data of critically ill patients from the emergency room in a tertiary teaching hospital from January 2010 to June 2011 were retrospectively studied.Binary Logistic regression analysis was used to determine possible factors and further compare the clinical characteristics of the patients.Results(1)From January 2010 to June 2011 a total of 11 468 patients were seen in the emergency department,the median ER length of stay was 11 h,a number of 6 525 patients(56.9％)stayed in ER more than 6 h.(2)Binary Logistic regression analysis showed that the main factors contributing to length of stay more than 6 hours were types of wards,green channel,treatment time,followed by admitted to ICU,traffic,sent by 120,the number of initial diagnosis,destinations of disposition,sex,holiday visit,visit month.While age,occupation,residence were not factors.Conclusions The patients in this hospital has a prolonged length of stay.The associated factors included types of wards,green channel,treatment time deserves a further study.%目的 探索影响急诊抢救室危重患者滞留时间的相关因素,为急诊管理者制定相关措施提供依据.方法 回顾性分析一家综合性医院2010年1月至2011年6月急诊抢救室危重患者的信息,通过二分类Logistic回归分析滞留时间的影响因素,并进一步比较主要影响因素特征.结果(1)2010年1月至2011年6月急诊抢救室共有危重患者11 468例,滞留的中位数时间为11h,滞留时间＞6h的有6 525例,占56.9％.(2)影响急诊危重患者滞留时间超过6h的主要因素有主诊科室、绿色通道、就诊时间段.其次为收入ICU、交通事故、120送入、初步诊断个数、离开抢救室去向、性别、节假日就诊、就诊月份.而患者的年龄、职业、户籍不是影响患者滞留时间超过6h的因素.结论 该家医院危重患者在抢救室滞留的时间偏长,主要受主诊科室、绿色通道、就诊时间段等因素影响,值得重视并进一步研究.
