[目的]探索影响住院天数的可控和不可控因素,为临床路径确定合理的住院天数提供理论依据。[方法]以沧州市2所医疗机构2004年出院的137名胆结石住院患者的病案首页信息为研究样本,采用多元线性回归分析方法探索与住院天数关系密切的各种因素。[结果]模型中有统计学意义的因素包括术前住院天数、手术方式、有无医院感染、年龄和入院时情况。[结论]选择比较单纯的外科病种作为临床路径的对象;根据手术方式、年龄和入院时情况等因素制订不同版本的临床路径;采取必要措施,降低术前住院天数和医院感染率。
[Objective] To explore the controllable and uncontrollable factors that affect the number of hospital days and provide the theoretical basis for determining the reasonable length of stay in clinical pathways. [Methods] The information of 137 cases of gallstone inpatients discharged from two medical institutions in Cangzhou City in 2004 was used as the research sample, and multiple linear regression analysis was used to explore various factors closely related to the days of hospitalization. [Results] There were statistically significant factors in the model including the length of preoperative hospitalization, the operation method, the presence or absence of nosocomial infection, the age and the condition of admission. [Conclusion] This study chose relatively simple surgical diseases as the target of clinical pathology. Different versions of clinical pathways were drawn according to the operation method, age and the condition of admission. The necessary measures were taken to reduce the number of days of preoperative hospitalization and hospital infection.
