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x±s表示，组间t检验，计数资料采用z。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。
OBJECTIVE To investigate related factors of nosocomial infection in patients undergoing radiologic imaging examinations and pathogen distribution and put forward preventive and protective countermeasures for susceptible factors so as to reduce the infection rate. METHODS Investigation of nosocomial infection was conducted for 3378 patients undergoing radiologic imaging examinations in our hospital for Jan. 2012 to Jan. 2013 as well as operators. Data were processed using the statistic software SPSS13. 0, the measurement data were shown in x ± s , t test was used for inter-group comparison and l test for the corvnt data. RESULTS Infection occurred in 156 cases, including 3 cases in medical staff and 153 cases in patients, the total infection rate was 4.62%. The infection rate for patients aged 〈14, 15-39, 40-59, ≥60 years were 3. 26%, 2.08%, 3.75%, 10. 04 %. The incidence of infection in patients ≥60 years was higher than that of other patients. Types of diseases accompanied with infection were, cerebrovascular disease （10.8%）, trauma and fracture （8.76%）, cardiovascular diseases （5.66%）, and circulatory system diseases （2.78%）. Infection sites were, in order, respiratory tract, incision, gastrointestinal infection, skin and soft tissue, accounting for 69. 23%, 15.38%, 9. 62% and 69.23%. Pathogenic bacteria were mainly gram-negative bacteria （105 strains, 67.30%）, followed by gram-positive bacteria （45 strains, 28.85%） and fungi （6 strains, 3.85%）, with Klebsiella pneumoniae , E. coli, and Staphylococcus aureus were main pathogenic bacteria. CONCLUSION Radiology department is an important department which cannot be ignored for prevention of nosocomial infection becanse it encounters high population flow, various types of diseases and long admission time. Measures such as strengthening the protection of operators and monitoring environmental disinfection and timely disinfection after examinations of special patients and patients with open injuries can reduce the nosocomial infecti
