Abstract:
Objective To investigate healthcare-associated infection(HAI)prevalence and antimicrobial use in a hospital.Methods HAI prevalence rate,antimicrobial use and pathogen detection in all inpatients on August 21 , 2013 were investigated with cross-sectional survey method.Results A total of 2 238 inpatients were investigated, 104 patients developed 126 times of HAI,HAI prevalence rate and case rate was 4.65% and 5.63% respectively;the top four sites for HAI were lower respiratory tract (28.57%),upper respiratory tract(18.25%),urinary tract (7.94%)and gastrointestinal tract(4.76%).Rate of specimens delivered for detection was 91 .35%(95/104),the main specimen was sputum (26.32%),followed by blood (25.26%)and urine (10.53%).Antimicrobial usage rate was 24.58%,therapeutic,prophylactic plus therapeutic,and prophylactic use accounted for 36.55%,45.09%, and 18.36% respectively;the usage rate of single,combination of 2,and 3 antimicrobial agents accounted for 75.82%,20.91 % and 3.27% respectively.Risk factors of HAI were age (<15 or >60 years),all kinds of inva-sive procedures (tracheotomy,mechanical ventilation,urinary catheterization,arteriovenous intubation,hemodialy-sis),and anti-tumor chemotherapy.Conclusion Survey on HIA prevalence helps to know the occurrence of HAI and usage of antimicrobial agents,as well as risk factors and high-risk departments of the occurrence of HAI,it also provides basis for subsequent targeted monitor on HAI.
