| Objective To investigate the nosocomial infection in our hospital, explore the influencing factors for nosocomial infection, and provide reference for prevention and control of nosocomial infection. Methods A retrospective investigation was performed among the annual discharge cases in 29 major departments of our hospital from Jan. 1, 2016 to Dec. 30, 2018, and nosocomial infection cases were statistically analyzed. The distributions of infected cases such as onset time, age and infection site were described. Results The incidence of nosocomial infection was 0.63% in 2016, 0.58% in 2017, 0.54% in 2018. There was no significant difference (P＞0.05). The highest infection rate was observed in intensive care unit, which was 6.95% in 2016, 6.48% in 2017, and 11.67% in 2018. The nosocomial infection was prevalent in summer and winter. The proportion of nosocomial infection in the respiratory system was the highest. The detection of pathogens showed that Gram-negative bacteria were dominant. Conclusions The incidence of nosocomial infection in our hospital is relatively lower in China.The incidence peaks in summer and winter. Advanced age and severe underlying disease are risk factors of nosocomial infection. Therefore, the management of departments such as intensive care unit and the prevention of respiratory infections in hospitalized patients should be strengthened to further reduce the incidence of nosocomial infections and improve the cure rate. |
