目的了解综合性重症监护病房医院感染现状,分析感染特点,以便加强防控。方法通过目标性监测,对本医院综合重症监护病房住院患者医院感染状况进行了监测。结果本医院重症监护病房2009-2011年3年期间共入住患者1 796例,发生感染患者296例次,例次感染率为16.48%,日感染率9.53‰。在接受侵入性操作患者中,静脉插管相关性血流感染率5.34‰、呼吸机相关性肺部日感染率3.86‰、留置导尿管相关性泌尿道日感染率3.31‰。从感染病人标本中共检出397株病原菌,革兰阴性菌占52.4%。结论本医院综合重症监护病房医院感染发生率较高,主要危险因素为血管内插管、机械通气和泌尿道插管等侵入性操作,必须有针对性地制定有效干预措施。
Objective To understand the current status of nosocomial infection in the intensive care unit and to analyze the characteristics of infection in order to strengthen prevention and control. Methods By means of targeted monitoring, the hospital infection status of inpatients in the intensive care unit of the hospital was monitored. Results A total of 1 796 patients were admitted to the intensive care unit during the three-year period from 2009 to 2011 in our hospital. There were 296 cases of infection among them. The rate of infection was 16.48% and the rate of daily infection was 9.53 ‰. In patients undergoing invasive procedures, the prevalence of venous intubation-related bloodstream infections was 5.34 ‰, ventilator-associated lung daily infection rates were 3.86 ‰, and indwelling catheter-associated urinary tract prevalence was 3.31 ‰. A total of 397 strains of pathogens were detected from infected patient samples, with Gram-negative bacteria accounting for 52.4%. Conclusion The prevalence of nosocomial infections in the intensive care unit of our hospital is high. The main risk factors are invasive procedures such as endovascular catheterization, mechanical ventilation and urinary catheterization. Effective interventions must be formulated.
