ABSTRACT

Objective To investigate the prevalence of healthcare-associated infection(HAI)in a children's spe-cialty hospital in Guangzhou in 2014.Methods A cross-sectional survey was undertaken to investigate the preva-lence of HAI among all hospitalized patients on September 17,2014.Results A total of 997 patients were investiga-ted,30 patients developed 32 times of HAI,HAI rate and HAI case rate were 3.01% and 3.21% respectively. The main infection sites were upper respiratory tract(n= 11,34.38% );the departments with higher HAI prevalence rates were intensive care unit(ICU,3 .99% )and pediatric internal medicine department(3 .60% );the rate of etio-logical examination in patients with HAI accounted for 93 .33% ,a total of 24 strains of pathogens were isolated,6 of which were virus (25 . 00% ),6 were fungi (25 . 00% ),11 were bacteria (45 . 83% ),and 1 was Chlamydia (4.17% ). The main bacteria were Staphylococcusaureus (n= 3,27.27% )and Staphylococcusepidermidis (n= 3, 27.27% );a total of 451 (45.24% )patients received antimicrobial agents on the investigation day,67.41% of whom received therapeutic use of antimicrobial agents,19.73% received prophylactic use,and 12.86% received both therapeutic and prophylactic use;mono-drug application accounted for 82 .26% ,the percentage of bacterial de-tection among patients with therapeutic antimicrobial use (including combination of therapeutic and prophylactic use)was 82.60% .Conclusion Management of key departments and key sites of HAI should be strengthened in children's specialty hospital,antimicrobial agents should be used rationally,so as to protect the safety of children.
