[Methods] The epidemiological analysis of nosocomial septicemia diagnosed in our hospital from 1992 to 1997 was conducted. [Results] The average incidence of nosocomial sepsis was 0.226%, with an overall increasing trend year by year. The incidence of male patients was significantly higher than that of females. There was no significant difference in age. The department of internal medicine was the highest in department of pathogenesis followed by surgery and pediatrics. Nosocomial sepsis, risk of death, high mortality, case fatality rate of 18.7%, the level of mortality is closely related to the number of hospital infections, the relevant issues with the literature were discussed. [Conclusion] The epidemiological analysis of nosocomial sepsis can help improve the awareness of medical staff about its harmfulness, and take more preventive measures to control nosocomial infections
