摘要
目的通过对ICU的目标性监测,了解ICU住院患者导管相关医院感染因素,并采取预防控制措施,以降低感染率。方法采用目标性监测方法对2011-2012年2592例ICU住院患者的医院感染进行监测,根据患者平均病情严重程度调整医院感染率,并对3种侵入性操作进行分析。结果 2011和2012年ICU患者感染例数分别为131例和136例,感染率分别为10.39%和10.37%,依病情严重程度(Average Severity of IllnessScore,ASIS)调整后日医院感染率分别为5.74‰及6.20‰;2011年和2012年呼吸机相关性肺炎(VAP)发生率分别为37.03‰和32.72‰,中心静脉插管相关血流感染率(CRBSI)分别为3.2‰和0.49‰,留置导尿管相关泌尿道感染率(CAUTI)分别为2.2‰合0.84‰;ICU医院感染以鲍氏不动杆菌及金黄色葡萄球菌为主。结论 2012年VAP、CRBSI和CAUTI较2011年有明显下降。
OBJECTIVE To investigate factors for the catheter-related infections in hospitalized patients of ICU through targeted surveillance and take .prevention and control measures so as to reduce the infection rate. METHODS By means of the targeted surveillance, the monitoring of incidence of nosocomial infections was performed for the 2592 ICU patients who were hospitalized during 2011--2012, then the incidence of nosocomial infections was adjusted according to the average severity of disease, and the three invasive operations were analyzed. RESULTS The infections occurred in 131 （10.39%） cases of ICU patients in 2011 and in 136 （10.37%） cases of ICU patients in 2012; according to the average severity of illness score, the adjusted daily infection rates were 5.74% and 6.20‰, respectively; the incidence rate of veatilator-associated pneumonia （VAP） was 37.03% in 2011, 32.72% in 2012; the incidence rate of central venous catheter-related bloodstream infection （CRBSI） was 3.2% in 2011, 0.49% in 2012; the incidence rate of indwelling catheter-associated urinary tract infection （CAU- TI） was 2.2% in 2011, 0.84% in 2012. The Acinetobacter baumannii and Staphylococcus aureus were the predominant species of pathogens causing nosocomial infections in ICU. CONCLUSION As compared with 2011, the incidence rates of VAP, CRBSI, and CAUTI are significantly decreased in 2012.
