Objective To investigate nosocomial infaction （NI） status in in - patients and analyse the influential factors, in order to provide reference for control of the NI incidence. Methods The data of NI in in - patients from Jan 2007 to Jun 2007 were reviewed and analysed. Results 13520 in - patients in this hospital were investigated. Among them, the NI incidence was 2.7%, the missing report rate of NI was 18.2% . The site with maximal incidence of NI was respiratory tract, accounting for 42.1% of all NI cases. The rate of NI of gastrointestinal tract was 14.2%, and the rates of NI of skin and soft tissue and urinary tract were 13.5% and 11.4% respectively, The important risk factors for N1 were age, days of hospital stay, urinary intubation and assisted ventilation. Conclusions The incidence of NI in this hospital was low, but the missing report rate of Ni was high. The risk factors for NI conform to the common conclusion.
