【摘要】：目的建立泌尿外科患者尿路感染的风险评分系统,为尿路感染的预防提供参考依据。方法选取2011年5月—2014年5月某院泌尿外科收治的470例住院患者作为研究对象,构建logistic回归模型进行影响因素分析,建立风险评分系统,利用ROC曲线评价模型预测效果。结果 470例泌尿外科患者发生尿路感染31例,感染发病率为6.60%。构建logistic回归分析显示,年龄、合并基础病、住院时间、留置导尿管时间和联合使用抗菌药物是尿路感染的独立危险因素。风险评分系统包括:年龄≥60岁得2分,有合并症得1分,住院时间≥10 d得3分,留置导尿管时间≥5 d得6分,抗菌药物使用种类≥2种得2分。分值≥11分为高危人群。模型评价显示,模型组ROC曲线下面积为0.89,灵敏度为84.9%,特异度为81.6%;验证组ROC曲线下面积为0.69,灵敏度为77.2%,特异度为62.4%。结论建立并验证了泌尿外科患者尿路感染风险评估系统,该风险评估系统有助于监测高危患者,降低感染的发生。
[Abstract]:Objective to establish a risk scoring system for urinary tract infection in Department of Urology and provide reference for the prevention of urinary tract infection. Methods 470 hospitalized patients admitted in a hospital from May 2011 to May 2014 were selected as the research object, and the logistic regression model was constructed to analyze the factors of influence factors and establish the risk scoring system and use the ROC curve. Results 31 cases of urinary tract infection occurred in 470 cases of Department of urology. The incidence of infection was 6.60%. construction logistic regression analysis showed that age, combined basic disease, hospitalization time, indwelling catheter time and combined use of antibiotics were independent risk factors for urinary tract infection. Risk scoring system included age more than 60 years old 2 points, 1 points for complication, 3 points for hospitalization longer than 10 d, 6 points for indwelling catheter time more than 5 d, 2 points for antibiotics with more than 2 species. The value of the model group is 0.89, the sensitivity is 84.9%, and the specificity is 81.6%, the model group ROC curve is 0.69 and the sensitivity is 77. 2%, specificity is 62.4%. conclusion and the establishment and validation of urinary tract infection risk assessment system in Department of urology. This risk assessment system helps to monitor high-risk patients and reduce the incidence of infection.
