【摘要】：目的调查放射科影像检查患者医院感染的相关因素及病原菌分布,针对易感因素提出防护对策,以减低医院感染率。方法对医院2012年1月-2013年1月放射科影像检查的3378例住院患者及操作人员进行医院感染调查,数据采用SPSS13.0统计处理,计量资料以s趚±s表示,组间t检验,计数资料采用χ2检验。结果共发生感染156例,其中医务人员3人、患者153例,感染发生率为4.62%;14、15~39、40~59、≥60岁患者感染率分别为3.26%、2.08%、3.75%、10.04%;≥60岁患者感染发生率明显高于其他年龄;感染率疾病类型依次为脑血管疾病、外伤及骨折、心血管疾病、循环系统疾病,感染率分别为10.8%、8.76%、5.66%、2.78%;感染部位依次是呼吸道、手术切口、胃肠道、皮肤及软组织感染,分别占69.23%、15.38%、9.62%、3.85%;检出病原菌以革兰阴性菌为主,共105株占67.30%、革兰阳性菌45株占28.85%、真菌6株占3.85%,以肺炎克雷伯菌、大肠埃希菌、金黄色葡萄球菌为主要病原菌。结论放射科人流量大、病种繁复且接诊时间长,是医院感染预防不可忽视的重要科室之一,加强操作人员的防护及环境消毒监测,特殊患者及开放性损伤患者检查后及时消毒等,可降低医院感染率。
[Abstract]:Objective to investigate the factors related to nosocomial infection and the distribution of pathogenic bacteria in radiologic imaging patients, and to propose protective measures against susceptible factors. Methods to reduce nosocomial infection rate, nosocomial infection was investigated in 3378 inpatients and operators from January 2012 to January 2013 in radiology department. The data were processed by SPSS13.0, the measurement data were expressed as s + s, and the count data were analyzed by 蠂 2 test. Results there were 156 cases of infection, 3 of them were medical staff. The incidence of infection was 4.62%. The infection rate of patients aged more than 60 was 3.262.08 and 3.750.04, respectively. The incidence of infection in patients aged more than 60 years was significantly higher than that in other age groups. The disease types of infection were cerebrovascular disease, trauma and fracture, cardiovascular disease, circulatory system disease, the infection rate was 10.8 and 5.66 respectively. The sites of infection were respiratory tract, surgical incision, gastrointestinal tract, skin and soft tissue infection, which accounted for 15.38% and 3.85% respectively. The main pathogens were Gram-negative bacteria (105 strains accounted for 67.30), Gram-positive bacteria 45 strains (28.85%), fungi 6 strains (3.85%), Klebsiella pneumoniae and Escherichia coli (Escherichia coli). Conclusion Staphylococcus aureus is one of the most important departments for the prevention of nosocomial infection. The hospital infection rate can be reduced by strengthening the protection of operators and monitoring of environmental disinfection and disinfection of special patients and patients with open injury.
