Methods A retrospective survey was conducted to investigate the inpatient nosocomial infections in this hospital in 2007. Results The hospital had 11,717 hospitalized patients in 2007, of which 401 cases were hospital-acquired and the nosocomial infection rate was 3.4%. In all infected sites, respiratory infections accounted for 54.2%, the elderly were susceptible populations. 101 hospital-acquired pathogenic bacteria and opportunistic pathogens were isolated and identified from 401 specimens of different nosocomial infections, mainly coagulase-negative staphylococci, Escherichia coli, Acinetobacter and Klebsiella pneumoniae.
