ABSTRACT
OBJECTIVE To study the clinical feature of nosocomial infection and analyze the correlative reasons,to offer the scientific theory basis for preventing and controlling the nosocomial infection. METHODS A retrospective survey was undertaken in the data of hospitalized cases during 2007. RESULTS Totally 2325 nosocomial infections in 54 505 patients were analyzed in 2007.The infection rate of nosocomial infection was 4.27%;the highest infection rate was in ICU(33.57%);the infection sites were different in distinct departments and the most common infection site was lower respiratory tract(27.19%);among pathogens isolated from nosocomial infection cases,48.05% of them were Gram-negatives,23.25% were virus,14.45% were fungi,and 14.15% were Gram-positives;the infection rate was diverse in different months. CONCLUSIONS Nosocomial infection rate is related to different underlying diseases;there are many effective actions to reduce the nosocomial infection,such as strengthening the nosocomial infection management,using the antibacterial drugs reasonably and preventing communicable diseases prevalence.
