Abstract: To investigate the present situation of nosocomial infection(NI) and the use of antibiotics and to provide scientific data for prevention and control of hospital infection. MethodsForms were filled with case data obtained from clinical investigations and references to inpatient medical records of all patients admitted to Qilu Hospital on 22th August 2007. ResultsAnalysis revealed that the prevalence rate of NI was 5.68% and the case prevalence rate was 5.93%, and the highest NI rate was found in the general ICU (36.36%). The respiratory tract was the main infected site (58.95%). The antibiotic adoption rate was 51.37%, and 59.30% of the antibiotics were singly used. Nine among 31 strains were identified as Escherichia Coli, 8 Pseudomonas aeruginosa, 2 Klebsiella pneumonia and 2 fungi. ConclusionsThe present NI rate survey indicates that targeted surveillance should be carried out in high risk departments, such as ICU, Department of Burns, Hemodia1ysis and Hematology, and it also helps doctors to properly use antibiotics to reduce the NI rate in the hospital.
