重症监护室病人医院感染现状调查

SURVEY ON THE CURRENT STATUS OF NOSOCOMIAL INFECTIONS IN ICU

目的了解重症监护室(ICU)医院感染现状,制定医院感染防控措施。方法采用目标性监测的方法,对某医院重症监护病房ICU患者医院感染情况进行调查。结果 2009年全年12个月内,该医院重症监护病房共入住患者867例,发生医院感染73例、158例次,感染发病率为8.42%,例次感染率为18.22%。平均病情严重程度ASIS评分为3.68分,调整病人日感染率为4.14‰,日医院例次感染率为8.94‰。在发生医院感染的病人中,呼吸机相关性肺炎占25.4‰,留置导尿管相关尿路感染占7.7‰,动静脉插管相关血流感染占7.4‰。结论重症监护病房病人医院感染发病率较高,感染部位以下呼吸道为主,应加强呼吸机相关肺炎的控制措施。

Objective To understand the current status of nosocomial infections in the intensive care unit,and to draw up the effective prevention and control measures for hospital infection.Methods Targeted surveillance method was used to make a survey on ICU patients with nosocomial infection.Results A total of 867 patients with ICU admission was monitored in 12 months of year 2009.73 cases and 158 case/times of hospital infection occurred and the infection rate was 8.42% while infection case/times rate was 18.22%.The average severity score was 3.68 points ASIS.The adjusted patients infection rate/day was 4.14% and case/times nosocomial infection rate/day was 8.94%.The three kinds of invasive infection related to the operation were ventilator-associated pneumonia（25.4%）,indwelling catheter associated urinary tract infection（7.7%） and vascular catheter-related bloodstream infection（7.4%）.Conclusion Nosocomial infection rate among ICU patients is comparatively high and the lower respiratory tract was the main infection site.So control measures for pneumonia related with breathing machines should be strengthened.
