Objective To investigate the efficacy of different methods of cleaning and disinfection on the surfaces of objects in fever clinics,so as to provide a basis for selecting appropriate methods on the surfaces of objects.Methods Frequently touched surfaces of objects in the fever clinical environment were divided into control and observation groups,cleaned and disinfected with chlorine-based disinfectants and hydrogen peroxide disinfectant wipes,respectively.Fluorescence labeling,ATP bioluminescence assay,and microbial processes were used to compare the clearance rates,ATP bioluminescence assay qualified rates,and bacterial colony count qualified rates of the two groups.Utilizing SPSS 20.0 software,the Chi-square test was applied for inter-group data analysis.A statistically significant difference analysis method with P＜0.05 was used to explore the effectiveness of cleaning and disinfection.Results Surfaces of high-frequency contact objects in fever clinics before and after intervention,the complete clearance rates for the removal of fluorescent markers using chlorine-based disinfectants and hydrogen peroxide disinfectant wipes were 80.47％and 95.03％respectively,the difference was statistically significant between the two groups(x2=35.95,P＜0.001).The qualified rates for ATP bioluminescence assay were 93.33％and 97.09％respectively,the difference was not statistically significant between the two groups(x2=2.15,P=0.143).The qualified rates for bacterial colony count were 98.65％and 98.04％respectively,the difference was not statistically significant between the two groups(x2=0.12,P=0.744).Conclusion Both chlorine-based disinfectants and hydrogen peroxide disinfectant wipes are effective for cleaning and disinfecting surfaces of objects frequently touched in hospitals.Comparative analysis reveals that hydrogen peroxide disinfectant wipes are simple and convenient to operate,causing less damage to medical staff,equipment,and facilities.Moreover,this method enhances work efficiency and operational compliance among medical staff,making it an ideal choice for cleaning and disinfection.
