2011-2013年我院消毒灭菌质量监测分析

Analysis and Monitoring of the Quality of Disinfection in Our Hospital From 2011 to 2013

目的:了解医院消毒、灭菌工作质量情况,及时掌握医院清洁消毒灭菌效果及存在的感染危险因素,为进一步完善医院的消毒隔离工作,控制医院感染,合理制定医院感染防控措施提供依据。方法:对医院室内空气、物体表面、医务人员手、消毒物品、灭菌物品、消毒清洗后的衣物、紫外线灯辐照强度、清洗消毒后的内镜及透析用水进行采样监测,并对监测结果进行分析。结果:3年共采样11 397份,合格10 971份,平均合格率为96.26%;2011-2013年合格率分别为95.77%、96.97%和96.08%,两个相邻年度间合格率比较差异均无统计学意义(P>0.05);各监测项目中,灭菌后物品、消毒后内镜和使用中的透析液合格率最高,均为100%,其次为空气和物体表面,合格率分别为97.68%和97.33%,紫外线灯和医务人员手,合格率最低,分别为93.93%和86.11%。结论:医院消毒质量总体较好,但仍有薄弱环节,特别是手卫生检测结果较低,应进一步加强医院手卫生监测工作,及时发现医院感染的各种隐患,降低医院感染的发生。

Objective：To understand the disinfection and sterilization quality of our hospital, grasp the effect of disinfection and sterilization and the risk factors of infection timely, in order to improve the disinfection and isolation work, control nosocomical infection, and provide a reasonable basis for making infection prevention and control measures.Method：The indoor air quality,body surface, medical personnel＇s hand, disinfection and sterilization items, after disinfection washing clothes, endoscope after cleaning and disinfection, ultraviolet lamp radiation intensity and dialysis water were sampled and monitored, and then the monitor results were analyzed.Result：A total of 11 397 samples in 3 years were collected, and 10 971 samples were qualified, the average total qualified rate was 96.26%. The qualified rate of 2011-2013 was 95.77%, 96.87% and 96.08% respectively, there was no obvious statistical difference between two adjacent year（P〈0.05）. Among the monitoring projects, after sterilization, disinfection after dialysis solution items endoscopy and use of qualified rate was highest, was 100%, followed by air and object surface, the qualified rate were 97.68% and 97.33%, the ultraviolet lamp and the hands of medical personnel, the lowest passing rate, respectively 93.93% and 86.11%.Conclusion：The quality of hospital disinfection is satisfactory,but there is still a weak link, especially the monitoring results of hygiene. However, we should further enhance the hand hygiene monitoring work in hospital,to find out various hidden risks of hospital infection, reduce the incidence of hospital infection.
