To investigate the present status of nosocomial infection, and to provide a reliable basis for further standardization and improve hospital infection monitoring scheme, management to carry out targeted monitoring work.

As the basic unit to ward, infection management of part-time doctors and nurses in different clinical departments were taken as investigators, and unified "prevalence survey of nosocomial infection by registration form" was used, by the way of case investigation and bedside combination. The prevalence of nosocomial infection of all patients in a day in our hospital were investigated.

Total of 1 856 patients were collected, among whom 1 841 patients were actually surveied, with the actual investigation rate of 99.19%. There were 50 cases with nosocomial infection, with the rate of 2.72%. There were 52 cases with hospital infection, with the rate of 2.82%. Total of 416 cases with infection in community, with the rate of 22.6%, there were 426 cases with community infection, with the rate of 23.14%. The infection of lower respiratory tract ranked the first in hospital infection and community-acquired infection, with 50.94% and 65.38%, respectively. Among the 50 cases with hospital infection, 23 cases were with Gram-negative bacteria infection, including 11 (47.83%) cases with Acinetobacter bacillus. The main pathogen infection in community was other pathogens (12 cases, 21.43%), Pseudomonas aeruginosa and E. coli followed by 17.86%, respectively. Among the 1 841 patients, there were 606 (32.92%) cases had used antibiotics; 34 (22.11%) cases taken for preventive medication, 442 (72.94%) cases taken for treatment, 30 (4.95%) cases taken for both prevention and treatment.

The prevalence survey reflected the dynamic infection in our hospital, and the key departments and points in the prevention and control of hospital infection were clear, a basis for the infection controls, the levels of understand and master for knowledge of hospital infection should be enhanced in our hospital, which fully proved to be a good infection control need the joint efforts of all levels of medical staff.
