Objective To understand the prevalence of hospital infection among hospitalized patients and analyze the risk factors of infection in order to provide basis for effective prevention and control measures. Methods A cross-sectional survey method was used to investigate the prevalence of nosocomial infections in hospital from September 14, 2011 to September 2011. Results 796 hospitalized patients were investigated. Among them, 27 cases of nosocomial infection occurred in 30 cases, the prevalence rate of nosocomial infection was 3.39%, and the prevalence rate was 3.77%. Infected parts of the main respiratory tract, the constituent ratio of 70.37%, of which 37.04% of the upper respiratory tract, lower respiratory tract was 33.33%. Antibiotics use rate of 40.70%, mainly to the treatment of medication. The main risk factors for nosocomial infections are the use of urinary and arteriovenous cannulas, immunosuppressive agents and chemotherapy, and invasive procedures such as surgery.
