ABSTRACT
Objective To analyze the medical environmental distribution characteristics of carbapenem-resistant Klebsiella pneumoniae (CRKP).Methods On April 25 and August 29,2016,random sampling was performed be-fore cleaning and disinfecting the surrounding of patients who isolated CRKP in a hospital,sampling were mainly object surfaces and medical devices.Distribution characteristics of CRKP were analyzed.Results The number of environmental sampling in surgical intensive care unit(SICU),respiratory ICU(RICU),and emergency ICU(EICU) were 90,41,and 56 respectively.CRKP was not found in SICU and RICU specimens;6 strains of CRKP were iso-lated in EICU,the isolation rate was 10.71%.In April 2016,103 specimens were taken,and 6 strains of CRKP were isolated,isolation rate was 5.83%,which was higher than in August of 2016(P <0.05).There were no sig-nificant differences in isolation rates of CRKP among different specimens and different responsible persons (all P >0.05).Conclusion Key departments,such as EICU,should be intensified cleaning and disinfection,so as to re-duce the spread of CRKP in the medical environment.
