目的:探讨消毒质量监测工作在预防医院感染和医源性感染工作中的作用,为做好医院感染和医源性感染预防工作提供科学依据。方法:通过对昌平区各级医疗卫生机构2007年-2009年消毒质量监测结果的回顾性分析,了解掌握医疗卫生机构在消毒工作中存在的问题。结果:2007年-2009年共采集样品3869件,合格3547件,合格率为91.68%;其中以2008年合格率最高为92.82%,2009年最低为89.92%,三年样品合格率相比较,差别有统计学意义(χ2=9.43,P<0.01);各类样品的合格率由高至低依次分别为污水(100%)、各类物体表面(96.89%)、压力灭菌器(96.23%)、消毒剂(95.29%)、医护人员手(92.74%),室内空气的合格率最低为69.05%。不同样品(除去污水)合格率相比较,差别有统计学意义(χ2=528.58,P<0.005)。结论:医疗卫生机构消毒质量监测工作对于有效预防医院感染和医源性感染有重要指导意义[1,2],但有待进一步加强和完善。
Objective: To explore the role of disinfection quality monitoring in the prevention of nosocomial infections and iatrogenic infections and to provide a scientific basis for the prevention of nosocomial infections and hospital infections. Methods: Through the retrospective analysis of the results of disinfection quality monitoring of medical and health institutions at all levels in Changping District from 2007 to 2009, understand the problems existing in the disinfection work of medical and health institutions. Results: From 2007 to 2009, a total of 3869 samples were collected, with 3547 passes, with a pass rate of 91.68%. Among them, the highest pass rate was 92.82% in 2008 and the lowest was 89.92% in 2009, with a difference of three years (Χ2 = 9.43, P <0.01). The pass rates of various samples from high to low were sewage (100%), surface of various objects (96.89%), pressure sterilizer , Disinfectant (95.29%), medical staff (92.74%), the lowest passing rate of indoor air was 69.05%. The differences of pass rates between different samples (except for sewage) were statistically significant (χ2 = 528.58, P <0.005). Conclusion: The monitoring of disinfection quality in medical and health institutions has an important guiding significance for the effective prevention of nosocomial infections and iatrogenic infections [1,2], but it needs to be further strengthened and improved.
