ABSTRACT
Objective To understand the clinical distribution characteristics and antimicrobial resistance of pathogens causing healthcare-associated infection(HAI) in a comprehensive hospital.Methods Clinical data of patients with HAI in this hospital between May 2012 and May 2015 were collected,the distribution and antimicrobial resistance of pathogens isolated from patients were analyzed.Results A total of 6 563 cases of HAI occurred among 183 850 patients,incidence of HAI was 3.57%,445 patients were isolated at least two kinds of pathogens,375 (84.27%) patients were isolated two kinds of pathogens,132 of whom were infected with both gram negative bacilli.4 478 specimens were sent for pathogenic detection,2 503 (55.90%) of which were isolated pathogens;a total of 2 755 pathogens were isolated,including 1 713(62.18%) strains of gram-negative bacilli,732(26.57%) gram positive cocci,304(11.03%) yeast-like fungi,and 6(0.22%) anaerobic bacteria.524(19.02%)strains were mainly from patients in department of neurology.The main specimen was sputum (n =1 340,48.64%).The isolation rates of carbapenem-resistant Escherichia coli (CREC),Klebsiella pneumoniae (CRKP),Acinetobacter baumnannii (CRAB),and Pseudomonas aeruginosa (CRPA) were 0.39% (2/510),1.66% (3/181),59.14% (207/ 350),and 5.29 % (11/208) respectively;isolation rate of methicillin-resistant Staphylococcus aureus (MRSA) was 21.55%(25/116).Conclusion Multidrug-resistant organisms causing HAl are various,it is necessary to understand distribution characteristics and prevalence of pathogens,monitor multidrug-resistant organisms,and implement contact isolation measures,so as to prevent the outbreak of HAI.
