新系统保洁对烧伤病房多重耐药菌感染的影响

The Effects of New Burn Ward Cleaning Methods on Multi-drug Resistant Bacteria Infection

目的探讨保洁方法对烧伤病房患者多重耐药菌感染的影响,改进、优化保洁流程和方法。方法采用回顾性分析法,将2012年11月-2013年10月烧伤病房的保洁消毒法称为传统保洁法,2013年11月-2014年10月烧伤病房的保洁消毒法称为新系统保洁法,比较新系统保洁法实施前后烧伤病房患者多重耐药菌的感染率。结果新系统保洁法实施前后的烧伤整形科患者多重耐药菌感染率分别为12.414‰、5.922‰,耐甲氧西林金黄色葡萄球菌感染率分别为7.286‰、3.718‰,耐碳青霉烯类铜绿假单胞菌感染率分别为2.699‰、0.689‰,差异均有统计学意义(P值均<0.05);耐碳青霉烯类鲍曼不动杆菌感染率分别为2.429‰、1.515‰,差异无统计学意义(P>0.05)。结论采用新系统保洁法能有效降低烧病房多重耐药菌感染率,值得临床推广和应用。

Objective To explore the effects of burn ward cleaning methods on multi-drug resistant bacteria infection,in order to improve and optimize the cleaning process and method.Methods From November 2012 to October 2013,the cleaning and disinfection methods in our burn wards were regarded as the traditional cleaning methods,and from November 2013 to October 2014,the cleaning and disinfection methods were called the improved cleaning methods（new system cleaning methods）.By retrospective analysis,we compared the infection rates of multidrug resistant bacteria before and after the implementation of the new system cleaning methods.Results New system methods were used in the ward environment cleaning and disinfection.The infection rate of multi-drug resistant bacteria before and after the implementation of the new system cleaning methods were 12.414%o and 5.922%o respectively.The methicillin resistant Staphylococcus aureus infection rate was 7.286%o and 3.718%o,and the carbon-resistant Pseudomonas aeruginosa infection rate was 2.699%o and 0.689%o.Both differences were significant（P〈0.05）.The carbon-resistant Acinetobacter baumanii infection rate was 2.429%o and 1.515%o before and after the implementation of the new methods with no significant difference（P〈0.05）.Conclusion Adopting new system to carry out cleaning can effectively reduce the infection rate of multi-drug resistant bacteria in the burn ward,and it is worthy of clinical popularization and application.
