[Objective] To understand the occurrence and clinical features of nosocomial infections and provide the basis for prevention and control of nosocomial infections. [Methods] The hospitalization records of hospitalized patients aged <30 years and> 59 years from 2007 to 2009 in Jiaozhou People’s Hospital were analyzed. [Results] Totally 20 427 medical records were investigated. There were 242 nosocomial infections with the infection rate of 1.18%. The incidence of nosocomial infection was 1.29%, 1.21% and 1.06% respectively from 2007 to 2009 (P> 0.05). The incidence of nosocomial infection was 0.87% and 0.92% for patients aged ≤19, 20-29, 60-69, 1.31% and 1.35% respectively. ICU was 2.75%, general surgery was 1.82%, respiratory medicine was 1.24%, endocrinology was 1.00%, obstetrics and gynecology was 0.80%, other departments were 0.63%. Among the 242 cases of nosocomial infections, the sites of infection were mainly lower respiratory tract, upper respiratory tract, gastrointestinal tract and urinary tract, accounting for 57.85%, 14.88%, 13.64% and 6.20% respectively. 218 pathogens isolated from infected samples, of which 35.32% of Escherichia coli, Staphylococcus aureus 31.19%, Pseudomonas aeruginosa accounted for 13.30%, pneumococcus accounted for 10.55%, Klebsiella accounted for 6.88% , Other bacteria accounted for 2.76%. [Conclusion] The hospital infection rate of Jiaozhou People’s Hospital is low.
