Objective To compare the point prevalence of nosocomial infection in a comprehensive hospital between 2014 and 2015, and to put forward prevention and control measures so as to reduce the incidence of nosocomial infection. Methods By means of reviewing electronical medical records and beside investigation, the prevalence rates of nosocomial infection in patients hospitalized on June 4, 2014 and June 16, 2015 were investigated. Data were collected by a uniform questionnaire and analyzed by Excel 2007 and SPSS 18.0. Results The nosocomial infection rates in those two time points were respectively 4.51% and 3.21% without a significant difference (χ²=2.246, P=0.134). Intensive Care Unit, Department of Neurosurgery and Department of Orthopedics were listed in the top five in terms of nosocomial infection rate for two consecutive years. The nosocomial infection sites were mainly lower respiratory tract, and a total of 64 strains were detected including mainly G^? bacteria accounting for 76.6%. Antimicrobial agent usage covered 34.05% and 33.33% at those two time points. The purpose was mainly for therapy, and the pathogenic bacteria specimen detection rate was 68.06% and 59.73%, without statistically significant difference (χ²=0.114, 3.311; P>0.05). Conclusion The prevalence of nosocomial infection in this hospital is at average national level but higher than the average level in Sichuan Province. Infection surveillance, prevention and control measures should be strengthened in key departments and key infection sites, and antimicrobial agent should be rationally used so as to reduce the incidence of nosocomial infection.
