摘　　要：目的了解老年重症监护病房(MICU)的医院感染发生情况和危险因素,为制定医院预防感染防控措施提供依据。方法采取目标性监测方法,对2013年2月-2014年1月入住MICU的所有住院患者进行调查,用ASIS法调整医院感染发病率,并对侵入性操作相关感染进行分析。结果 652例MICU住院患者中,发生医院感染76例,感染率为11.66%,日感染率为15.39‰,ASIS法调整后日感染率为4.57‰;呼吸机相关性肺炎、导管相关性血流感染、导尿管相关性尿路感染的感染率分别为17.54‰、9.17‰、7.92‰。共检出病原菌139株,以革兰氏阴性菌为主,占75.54%。结论 MICU的患者是医院感染的高危人群,发生医院感染主要以导管相关感染为主,实施目标性监测能及时发现医院感染的隐患,及时采取干预措施,以有效降低医院感染的发生。OBJECTIVE To understand the prevalence of nosocomial infections in medical intensive care unit （MICU） and explore the risk factors so as to provide guidance for prevention and control of the nosoeomial infec- tions. METHODS By means of the targeted monitoring, all of the patients who were hospitalized in the MICU from Feb 2013 to Jan 2014 were investigated, then the incidence of nosocomial infections was adjusted bY using ASIS method, and the invasive procedures-related infections was analyzed. RESULTS Of the 652 patients who were hos- pitalized in the MICU, 76 had nosocomial infections, with the infection rate 11.66‰, the daily infection rate 15. 39‰, and the daily infection rate was 4.57‰ after it was adjusted by ASIS method. The incidence rates of ventila- tor-associated pneumonia, catheter-related bloodstream infection, and urinary catheter-related urinary tract infec- tions were 17. 54‰, 9.17‰, and 7.92‰, respectively. A total of 139 strains of pathogens were isolated, of which 75.54‰,were gram-negative bacteria. CONCLUSION The MICU patients are the population at high risk of the nosocomial infections, and the patients with catheter-related infection are dominant among the patients with the nosocomial infections. It is an effective way to conduct the targeted monitoring to find out the hidden dangers in a timely manner and take the interventiofi measures so as to reduce the incidence of the nosocomial infections.
