Abstract
Objective To investigate the status and change trend of healthcare-associated infection (HAI)in a tumor hospital,so as to provide reference for formulating scientific control measures of HAI and strengthening management of HAI.Methods According to the requirement of the National HAI Surveillance Network,on Sep-tember 19,2012,August 20,2013 and August 13,2014,survey on HAI prevalence rates among all hospitalized pa-tients in this hospital were carried out,data were analyzed statistically.Results The prevalence rates of HAI from 2012 to 2014 were 6.93%,8.82%,and 8.10% respectively;lower respiratory tract was the main infection site in three years,accounting for 30.00%,53.85%,and 47.44% respectively;followed by upper respiratory tract,ab-dominal (pelvic)tissue,superficial incision,and urinary tract.Gram-negative bacilli were the main pathogens cau-sing HAI,accounting for 71 .43%,66.67%,and 72.97% respectively,the detection rate of Escherichia coli was the highest.Antimicrobial usage rates in 2012-2014 were 18.23%,13.64%,and 17.70% respectively;pathogenic detection rates in patients receiving therapeutic antimicrobial use were 74.51 %,57.14%,and 55.68% respectively (χ2 = 15.122,P =0.001 ).Antimicrobial usage rates in type Ⅰ incisional operation were 0.78%,6.25%,and 8.33% respectively.Conclusion Survey of HAI prevalence rate is helpful for realizing the current situation of HAI and deficiency of prevention and control of HAI,taking targeted measures,and reducing incidence of HAI.关键词
