某基层综合医院10年医院感染流行趋势

The epidemic tendency analysis of nosocomial infection in a primary comprehensive hospital in ten years

目的了解某基层医院10年医院感染发生的基本规律,分析其流行特征与发生趋势。方法通过综合性监测和目标性监测相结合的方式,对该基层医院10年医院感染监测资料进行相关统计分析。结果 10年医院感染平均例次率为2.05%,漏报平均例次率为23.90%。前三位高发科室依次为ICU、神经内科和肾内科,最常见感染部位为下呼吸道、上呼吸道和泌尿道,感染病原菌以革兰阴性杆菌为主,病原体以大肠埃希菌、铜绿假单胞菌和肺炎克雷伯菌为主。10年间医院感染例次率呈现先下降后平稳趋势,漏报例次率则出现了逐年下降趋势。结论该基层医院医院感染发生总体水平不高,但漏报较高,在医院感染管理部门采取有效措施后,呈现明显下降趋势。

Objective To understand the epidemiological characteristics and trend of nosocomial infections in ten years in a primary hospital. Methods Data from comprehensive monitoring and target monitoring systems were analyzed statistically.Results In 10 years,the average case-time rate of nosocomial infection was 2.05%,and the average missing report case-time rate was 23.90%. The top three hospital departments with high infection rates were ICU,Department of Neurology and Department of Nephrology. The most frequent sites of nosocomial infection were the lower respiratory tract,the upper respiratory tract and the urinary tract. Gram negative bacteria were the main pathogens of infection,and the main pathogens were Escherichia coli,Pseudomonas aeruginosa and Klebsiella pneumoniae. Hospital infection case- time rate in 10 years showed a steady trend after the first decline,the missing report case-time rate showed a declining trend year by year.Conclusion The overall level of infection case-time rate in this hospital was not high,but the missing report case-time rate was higher. After effective measures were performed by hospital infection management department,the infection case-time rate has been obviously improved.
