中文摘要：
目的 分析基层医院导尿相关尿路感染的相关危险因素。方法218例接受导尿的患者中，并发尿路感染者79例，为试验组；未发生感染者139例，为对照组。记录年龄、性别、住院诊断、尿管留置时间、是否预防性使用抗生素、卧床时间、是否膀胱冲洗等因素。结果Logistic多因素统计分析显示尿管留置时间≥7天（OR值5．59；95％CI1．94～16．16）、卧床时间≥15天（OR值4．23；95％CI1．85～9．67）、膀胱冲洗（OR值3．63；95％CI1．83～7．23）与导尿并发尿路感染明显相关。结论尿管留置时间≥7天、卧床时间≥15天、膀胱冲洗是导尿并发尿路感染的独立危险因素。
英文摘要：
Objective To analyze the risk factors of catheter-related urinary tract infection in the primary hospital. Methods 218 cases who have undergone urethral catheterization were included in our study： the experimental group included 79 cases with complicated urinary tract infections; the control group included 139 cases with no urinary tract infection. Results The multivariate logistic regression model showed that indwelling catheter time ≥7 days （OR=5.59; 95% CI = 1.94 - 16.16）, bed time 〉 15 days （OR = 4.23; 95% CI = 1.85 - 9.67） , bladder irrigation （OR = 3.63; 95% CI = 1.83 - 7.23） were associated significantly with catheter-related urinary tract infection. Conclusion Indwelling catheter time≥ 7 days, bed time ≥ 15 days, bladder irrigation are independent risk factors for catheter-related urinary tract infection.
