摘要
目的分析骨科患者泌尿道医院感染的影响因素,为其医院感染的预防治疗提供理论依据。方法回顾性分析2011年3月-2013年3月2680例骨科住院患者临床资料,采用单因素χ2检验统计分析骨科患者泌尿道医院感染的危险因素。结果 2680例骨科住院患者中共发生泌尿道医院感染76例,其感染率为2.8%;76例骨科住院泌尿道感染患者中共培养出合格病原菌62株,阳性率为81.6%,其中革兰阴性菌40株占64.5%,革兰阳性菌15株占24.2%,真菌7株占11.3%;革兰阴性菌主要以大肠埃希菌、肠杆菌属和克雷伯菌属为主,分别占45.2%、12.9%和6.5%;革兰阳性菌以肠球菌属和葡萄球菌属为主,分别占14.5%和9.7%;单因素χ2检验显示,女性、年龄>50岁,留置尿管、尿管留置时间>7d的患者具有较高的泌尿道医院感染发生率(P<0.05)。结论骨科泌尿道医院感染的致病菌主要是革兰阴性菌,女性、年龄>50岁,留置尿管、尿管留置时间>7d是骨科患者泌尿道医院感染的危险因素,积极采取相应的预防措施可降低其感染发生率。
OBJECTIVE To investigate the risk factors for urinary tract infections in patients of orthopedics depart-ment so as to provide theoretical basis for the prevention and treatment of nosoeomial infections, METHODS The clinical data of 2680 cases of patients who were hospitalized in the orthopedics department from Mar 2011 to Mar 2013 were retrospectively investigated, then the risk factors for the urinary tract infections were statistically analyzed with the use of ehi-square test. RESULTS The urinary tract infections occurred in 76 of 2680 hospitalized patients with the infection rate of 2.8 %. Of the 76 cases of urinary tract infections, totally 62 strains of eligible pathogens were isolated with the positive rate of 81.6%, including 40 （64, 5%） strains of gram-negative bacteria, 15 （24.2%） strains of gram-positive bacteria, and 7 （11.3%） strains of fungi; the Escherichia coli, Enterobact-er, and Klebsiella were the main species of gram-negative bacteria, accounting for 45, 2%, 12.9%, and 6.5%, respectively; the Enterococci and Staphylococci were dominant among the gram-positlve bacteria, accounting for 14.5 % and 9.7 %, respectively. The univariate chi-square test indicated that the incidence of urinary tract infec-tions was relatively high in the patients with the gender of female, more than 50 years of age, catheter indwelling, or catheter indwelling duration more than 7 days （P〈0.05）. CONCLUSION The gram-negative bacteria are the main pathogens causing urinary tract infections in the orthopedics department; the gender of female, more than 50 years of age, catheter indwelling, and catheter indwelling duration more than 7 days are the risk factors for the urinary tract infections; taking corresponding prevention measures can reduce the infection rate.
