Abstract:
Objective To realize the isolation of multidrug-resistant organisms (MDROs)from ward environment, and provide evidence for clinical prevention and control of MDRO transmission.Methods Patients with MDRO in-fection in a stomatology hospital from September 2012 to July 2014 were as trial group,12 randomly selected pa-tients without MDRO infection were as control group,environmental object surface in patients’ward were taken specimens and performed culture,isolated organisms were identified and performed antimicrobial susceptibility tes-ting.Results Of 44 patients with MDRO infection,13 patients’surrounding environment were detected MDROs,the total detection rate was 29.55%(13/44).The detection rate of methicillin-resistant Staphylococcus aureus (MRSA),multidrug-resistant Acinetobacter baumannii (MDRAB),and methicillin-resistant Staphylococcus epidermidis (MRSE)were 45.45%(5/11),66.67% (2/3)and 66.67%(6/9)respectively.Detection rates of MRSA from nasal cavity and hands of MRSA-infected patients were 72.73% and 54.54% respectively,from nasal cavity and hands of patients’caregivers were 36.36%and 18.18% respectively.The difference in bacterial count between trial group and control group was not significantly dif-ferent (all P >0.05).Conclusion Isolation rate of MDROs from ward environment of MDRO-infected patients is higher than that of non-MDRO-infected patients,monitoring,cleaning and disinfection for MDRO-infected patients’surrounding environment should be strengthened,so as to prevent the spread of MDROs in hospital.
