Cross-sectional survey on healthcare-associated infection in a hospital in 2014 / 中国感染控制杂志

ABSTRACT

Objective To investigate the current status of healthcare-associated infection(HAI)and antimicrobial usage,so as to provide a scientific basis for improving the management of HAI. Methods A cross-sectional survey was conducted by combination of bedside visiting and medical records reviewing,HAI were investigated among all hospitalized patients between 000 and 2400 on August 21 ,2014.Results A total of 2 216 patients were investiga-ted,the prevalence rate of HAI was 4.83% ,the case infection rate was 5.14% ;the main infection site was lower respiratory tract(63.16% ),antimicrobial usage rate was 39.71% ,the proportion of prophylactic and therapeutic use of antimicrobial agents was 32.27% and 61 .71% respectively.596 patients received therapeutic antimicrobial use,specimen detection rate was 56.21% (n= 335),the detection rate of pathogens was 15.52% (n= 52). The ma-jor detected bacteria were Pseudomonasaeruginosa,Klebsiellapneumoniae,Acinetobacterbaumannii,Escherichia coli,and Stenotrophomonasmaltophilia.Conclusion HAI prevalence survey is helpful for realizing the occurrence of HAI,respiratory tract is the main infection site,gram-negative bacteria is the major pathogen,management of prophylactic use of antimicrobial agents is the focus of HAI management.
