Results A total of 1165 hospitalized patients were investigated from the year 2011 to 2012,and the actual check rate was 100%.A total of 46 cases of hospital infection occurred in 39 patients.The prevalence rate of hospital infection was 3.88% in 2011 and 2.80% in 2012.High rate hospital infections occurred in the Department of Neurosurgery which was 27.27% and Cardiothoracic surgery which was 16.67% in 2011.In 2012,the departments included ICU which was 28.57% and Internal Cardiovascular Medicine which was 9.09%.The main infection sites were respiratory tract,followed by urinary tract and superficial incisions.The usage rates of antibiotics were 63.07% and 40.56% respectively in the two years.There were significant difference in antibiotic use rate between the two years (P<0.01).
