目的了解内蒙古自治区部分医院重症监护病房(ICU)医院感染情况,为采取实时防控措施提供参考。方法采取前瞻性目标监测方法,对该自治区所属28所医院ICU住院患者医院感染状况进行监测与分析。结果2013年度共监测28所医院ICU住院患者7 255例,发生医院感染357例,感染率为4.92%。血管导管相关血流感染、导管相关泌尿道感染和呼吸机相关肺炎日感染率分别为1.56‰、2.26‰和10.02‰。从357例医院感染患者送检标本中共分离病原菌473株,以鲍曼不动杆菌、铜绿假单胞菌、金黄色葡萄球菌和肺炎克雷伯菌为主要优势菌。结论内蒙古自治区医院ICU住院患者医院感染率明显高于同地区医院平均值,侵入性操作,无菌操作和护理是关键防控环节。
Objective To understand the prevalence of nosocomial infections in intensive care unit (ICU) hospitals in Inner Mongolia Autonomous Region and to provide reference for taking real-time prevention and control measures. Methods The prospective target monitoring method was used to monitor and analyze the hospital infection status of inpatients in ICU of 28 hospitals in this autonomous region. Results In FY 2013, a total of 7 255 hospitalized patients in ICU in 28 hospitals were monitored. 357 cases of nosocomial infection occurred and the infection rate was 4.92%. The daily infection rates of vascular catheter-related bloodstream infections, catheter-related urinary tract infections and ventilator-associated pneumonia were 1.56 ‰, 2.26 ‰ and 10.02 ‰, respectively. A total of 473 pathogenic bacteria were isolated from 357 hospital-acquired patients, and Acinetobacter baumannii, Pseudomonas aeruginosa, Staphylococcus aureus and Klebsiella pneumoniae were the main dominant bacteria. Conclusion The hospital infection rate of hospital ICU in Inner Mongolia Autonomous Region was significantly higher than that of the same district hospitals. Invaded operation, aseptic operation and nursing were the key prevention and control links.
