Cross-sectional survey on nosocomial infections in Zhejiang Cancer Hospital in 2011 and 2012 / 中华临床感染病杂志

ABSTRACT

Objective To investigate the prevalence rate of nosocomial infections and the use of antibacterial agents in Zhejiang Cancer Hospital.Methods The cross-sectional survey on nosocomial infections was conducted among inpatients in Zhejiang Cancer Hospital on August 11,2011 and June 19,2012.The differences in prevalence rates of nosocomial infections,purposes of antibacterial agents use (for treatment,for prevention,or for both treatment and prevention),methods of medication (single or combined medication),and pathogen detections between 2011 and 2012 were analyzed with x2 test.Results There were 854 and 886 patients enrolled in the study in 2011 and 2012,and the prevalence rates of nosocomial infections were 5.27％ (45/854) and 5.08％ (45/886),respectively (x2 =0.186,P ＞ 0.05).Lower respiratory tract infection was the most common nosocomial infections both in 2011 and 2012,which accounted for 28.89％ and 36.96％ of all infections,respectively; and there was no significant difference in infection sites between 2011 and 2012 (x2 =1.415,P＞0.05).Totally 154 out of 854 patients (18.03％)in 2011 and 186 out of 886 patients (20.99％) in 2012 received antibacterial agents,and single medication was the most common.There were no significant differences in the purposes and methods of medication between 2011 and 2012 (x2 =1.994 and 3.042,P ＞ 0.05).Pathogen detections were performed in 56 out of 59 patients (94.92％) and 57 out of 65 patients (87.69％) who received antibacterial agents for treatment in 2011 and 2012,respectively.The most common pathogens were Escherichia coli,Pseudomonas aeruginosa,and Acinetobacter baumanni.Conclusion The prevalence rate of nosocomial infection in Zhejiang Cancer Hospital is of the satisfactory level,which is due to the good management of antibacterial agents use.
