重症加强治疗病房内超长住院日患者分布特征与预后影响因素分析

Distribution Characteristics and Prognostic Risk Factors Analysis of Critically Ill Patients with Prolonged Stay in Intensive Care Unit

目的探讨ICU内长时间住院患者的分布特征与预后影响因素。方法通过医院信息系统(HIS)对2003年1月至2009年7月间ICU内119例长期住院患者的临床信息进行回顾性分析,并按照出院结局分为生存组与死亡组进行比较,利用二元Logistic回归模型分析超长住院患者的预后影响因素。结果单因素分析发现,患者年龄、付费类别、病种以及ICU住院时间在生存组与死亡组之间均有显著差异(P均<0.05),Logistic回归分析显示年龄、ICU住院时间以及是否输血浆是影响预后的独立危险因素。结论ICU内超长住院日患者的预后受年龄、住院时间以及是否输血浆等因素影响,对具备上述高危因素的患者应加强监护。

Objective To explore the distribution characteristics and prognostic risk factors of critically ill patients who has long-term hospitalization in intensive care unit（ICU）.Methods A retrospective study was carried out to evaluate 119 critically ill patients from January 2003 to July 2009 by extracting data from computerized hospital information system.The patients were divided into a survival group and a non-survival group based on discharging outcomes.A binary logistic regression analysis was introduced to investigate potential risk factors of prognosis.Results Age,type of payment,entity of disease,and length of ICU stay were significantly different between the two groups（P0.05）in independent-Samples T test.Logistic regressions indicated that age,length of ICU stay and plasma infusion were independent predictors for worse outcome.Conclusions Age,length of ICU stay and plasma infusion may directly influence the prognosis of patients with prolonged stay in ICU.Intensive therapies should be emphasized for those patients at high risk.
