【摘要】：目的探讨重症监护病房(ICU)留置导尿管患者发生导尿管相关泌尿道感染(CAUTI)的危险因素及感染病原体分布。方法回顾性调查2014年1—12月某院综合ICU收治的留置导尿管患者,调查患者基本情况、导尿管使用情况及CAUTI发病情况,分析CAUTI发生的危险因素及病原体分布。结果共调查留置导尿管患者778例,52例患者发生CAUTI,发病率为6.68%。单因素分析结果显示女性、年龄≥60岁、入住ICU时间≥7 d、留置导尿管时间≥3 d、有慢性基础疾病、使用抗菌药物两种及以上是CAUTI发生的危险因素。多因素分析结果显示入住ICU时间≥7 d和留置导尿管时间≥3 d是发生CAUTI的独立危险因素,OR及95%CI分别为30.64(19.71~64.97)、38.69(21.38~74.03)。CAUTI患者感染病原菌以革兰阴性(G-)菌为主(59.04%),其中大肠埃希菌占26.51%。结论留置导尿管患者发生CAUTI与多种因素有关,应结合患者病情尽量减少患者入住ICU时间及其留置导尿管时间,结合病原学检查结果合理使用抗菌药物。
[Abstract]:Objective to investigate the risk factors of urethral catheter associated with urinary tract infection (CAUTI) and the distribution of pathogens in patients with indwelling urethral catheter in intensive care unit (ICU). Methods retrospective investigation was made on the patients with indwelling urethral catheter treated in a hospital with ICU from January to December, 2014. To investigate the basic condition of the patients, the use of catheter and the incidence of CAUTI, The risk factors and pathogen distribution of CAUTI were analyzed. Results A total of 778 patients with indwelling catheter developed CAUTI.The incidence rate was 6.68.The univariate analysis showed that female, age 鈮，
