泌尿系肿瘤患者尿路感染危险因素Logistic回归分析

Logistic Regression Analysis of Risk Factors for Urinary Tract Infection in Patients with Urinary Tract Cancer

目的探讨引起泌尿外科肿瘤住院患者尿路感染的危险因素。方法回顾性分析了200例泌尿外科肿瘤住院病历,将肿瘤合并尿路感染者作为观察组,按1∶1选择同期无尿路感染泌尿外科患者作为对照组,对可能的影响因素先进行了单因素V^2、t检验;然后将单因素分析差异有统计学意义的变量进行多元逐步Logistic回归分析。结果 200例患者中合并尿路感染26例,发生率为13%;单因素分析了7个变量是尿路感染有影响的危险因素(P<0.05),采用了Logistic回归分析,筛选出独立危险因素,按OR值的大小,依次为年龄大、伴有创诊治措施、合并其他的疾病。结论泌尿外科肿瘤住院患者尿路感染的发生率较高,影响尿路感染因素较多,应针其因素给予针对性的预防措施。

Objective To investigate the risk factors of urinary tract infection in patients with tumor in Department of urology. Methods a retrospective analysis was made on 200 cases of tumor in Department of Urology,The tumor associated with urinary tract infection as the observation group,According to 1： 1 choice compared with no urinary tract infection of urological patients as the control group,on factors that may affect the first single factor V2 and t test; then the single factor analysis,the difference is statistically significant variables of multivariate stepwise logistic regression analysis. Results in 200 patients with urinary tract infection in 26 patients,the incidence rate of 13%; univariate analysis of the seven variables is urinary tract infection effects of risk factors（ P〈0. 05）,using logistic regression analysis,independent risk factors were screened out,or by value size,followed by age,accompanied by a diagnosis and treatment measures,combined with other diseases. Conclusions The incidence of urinary tract infection in patients with tumor in Department of Urology is high,and the factors affecting urinary tract infection are more,and the preventive measures should be given according to the factors.
