重症监护病房医院感染目标性监测分析

Targeted Surveillance of Nosocomial Infection in Intensive Care Unit

目的通过对重症监护病房(ICU)开展目标性监测,探讨降低医院感染率的对策。方法采用目标性监测方法,对2010年10月—2011年11月ICU收治的患者进行调查与分析。结果 ICU医院感染例次发病率为21.23%,日感染例次发病率为15.02‰,根据病情严重程度调整后的日感染例次发病率为4.20‰,血管导管相关性血流感染率为5.17‰,导尿管相关性泌尿道感染率为4.36‰,呼吸机相关性肺炎感染率为5.79‰。最常见的病原菌为不动杆菌属和金黄色葡萄球菌,其次为铜绿假单胞菌。结论 ICU医院感染发病率较高,目标性监测是降低ICU医院感染发生的科学方法。

Objective To explore the countermeasures of reducing the nosocomial infection（NI） rate through conducting targeted monitoring in intensive care unit（ICU）.Methods The inpatients in ICU during October 2010-November 2011 were investigated and analyzed by targeted surveillance methods.Results NI incidence in ICU was 21.23%,the daily NI incidence was 15.02‰.The daily NI incidence adjusted according to average severity of illness score（ASIS） was 4.20‰.The intravascular catheter-related bloodstream infection rate was 5.17‰,the urinary catheter-related infection rate was 4.36‰,the ventilator associated pneumonia infection rate was 5.79‰.The most common pathogens causing nosocomial infections in ICU were Acinetobacter and Staphylococcus aureus,followed by Pseudomonas aeruginosa.Conclusion NI incidence is high in ICU,and targeted surveillance in ICU is a scientific monitoring method to reduce it.
