Application of fluorescent labeling method and microbiological method in the effect evaluation of environmental cleaning and disinfection in ICU
Objective To explore the application effect of fluorescent labeling method and microbiological method in evaluating the quality of cleaning and disinfection of the surrounding environment of patients with multidrug-resistant organism infection/colonization in intensive care units(ICU).Methods Focusing on the surrounding environment of all patients with carbapenem-resistant Acinetobacter baumannii infection/colonization in 12 ICUs in the hospital,fluorescent labeling methods and microbiological methods were used to compare the fluorescent labeling clearance rate,the qualified rate of microbial specimens and the detection rate of Acinetobacter baumannii of each ICU before and after the implementation of environmental cleaning intervention measures.Results After the intervention,the fluorescence labeling clearance rate increased from 35.85%to 66.94%,and the qualified rate of microbial specimens increased from 80.57%to 93.13%.The detection rate of Acinetobacter baumannii decreased from 27.43%to 8.75%,and the differences were all statistically significant(P<0.05).Conclusion Fluorescent labeling method and microbiological method can be used to evaluate the effect of object surface cleaning and disinfection in patients with multidrug-resistant organism infection/colonization.
