Investigation and analysis of disinfection quality after implementing intervention measures in old-age care institutions of Qingpu district in Shanghai

目的通过采取干预措施,规范辖区内养老机构消毒流程及措施,提高养老机构消毒质量。方法按等级随机选择规模和卫生条件相近,配合程度高的6所养老机构,分试验组与对照组,在实施干预前、后对物体表面、工作人员手、老年人手、餐饮具及室内空气进行消毒效果监测。结果干预前共监测样品323件,合格率为72. 76%。干预前试验组与对照组样品合格率分别为75. 6%和69. 9%,差异无统计学意义(P=0. 25);干预后试验组与对照组样品合格率分别为80. 5%和62. 0%,差异有统计学意义(P=0. 00)。结论养老机构内护理人员手、餐饮具及抹布等环节微生物的污染比较严重,通过采取一系列的综合性干预措施,能提高各环节消毒监测样品合格率。

Objective To standardize the disinfection process and measures of old-age care institutions within the area under administration so as to improve the qualified rate of disinfection monitoring of old-age care institutions.Methods According to the grades,6 old-age care institutions with similar scale and sanitary conditions and high degree of cooperation were randomly selected,which were divided into the experimental group and the control group.Before and after the intervention,the disinfection effects of object surfaces,the hands of staff and elderly people,the tableware and indoor air were monitored.Results A total of 323 samples were monitored before the intervention,and the qualified rate was 72.76%.The qualified rate of samples in the experimental group and the control group before intervention was 75.6%and 69.9%,respectively,and the difference was not statistically significant(P=0.25).After intervention,the qualified rate of samples in the experimental group and the control group was 80.5%and 62.0%,respectively,with statistically significant difference(P=0.00).Conclusion The microbial contamination of nursing staff’s hands,tableware and dishcloth in old-age care institutions is relatively serious.By adopting a series of comprehensive intervention measures,the qualified rate of disinfection monitoring samples in each link can be improved.
