基层医院导尿相关尿路感染的危险因素分析

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%CI 1.94～16.16)、卧床时间≥15天(OR值4.23;95%CI 1.85～9.67)、膀胱冲洗(OR值3.63;95%CI 1.83～7.23)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。

Analysis of the Risk Factors for Catheter-related Urinary Tract Infection in the Primary Hospital

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 In-dwelling catheter time ≥7 days,bed time ≥15 days,bladder irrigation are independent risk factors for catheter-related urinary tract infection.
