OBJECTIVE
To describe the occurrence, microbiology, and risk factors of catheter- associated urinary tract infections (CA-UTI) in critically ill children.
METHODS
We conducted a review of hospital records for CA-UTI in the pediatric intensive care unit (PICU) over a 7-year period (2014-2020).
RESULTS
62 CA-UTI cases (48% boys, median (IQR) age 36 (12,96 month) were identified during the study period with occurrence rate of 7.2/1000 catheter-days. The most common organisms were Escherichia coli (32.4%) and Enterococcus faecalis (30.6%). Using a multivariate logistic regression analysis, the significant associated variables for CA-UTI were duration of catheter drainage (a OR (95% CI) 1.14, (1.03,1.27), P=-0.009), PICU stay (aOR (95% CI) 1.13 (1.05,1.21) (P<0.001), and hospital stay (aOR (95% CI): 1.03 (1.01,1.06), P=0.015).
CONCLUSION
CA-UTI is not an uncommon nosocomial infection in PICU. The risk increases with increasing duration of catheter drainage, and hospital or PICU stay.
目的
描述危重症患儿中心导管相关尿路感染（CA-UTI）的发生情况、微生物学特征和危险因素。
方法
我们对 7 年间（2014-2020 年）小儿重症监护病房（PICU）中与中心导管相关的尿路感染（CA-UTI）的医院记录进行了回顾性研究。
结果
研究期间共发现 62 例 CA-UTI 病例（48%为男性，中位（IQR）年龄为 36（12，96 个月），发生率为 7.2/1000 导管日。最常见的病原体是大肠埃希菌（32.4%）和粪肠球菌（30.6%）。使用多变量逻辑回归分析，CA-UTI 的显著相关变量是导管引流时间（比值比（95%可信区间）1.14，（1.03，1.27），P=0.009）、PICU 住院时间（比值比（95%可信区间）1.13（1.05，1.21）（P<0.001）和住院时间（比值比（95%可信区间）：1.03（1.01，1.06），P=0.015）。
结论
CA-UTI 在 PICU 中并非一种罕见的医院获得性感染。风险随着导管引流时间、医院或 PICU 住院时间的增加而增加。
