Abstract Objective To investigate the situation of nosocomial infection, the use of antibiotics and the submission of pathogens culture in a general hospital, so as to provide data support for the prevention and control of nosocomial infection.Methods A cross-sectional survey of nosocomial infection was conducted in all inpatients on the survey days of each year from 2016 to 2021. Excel 2016 and SPSS 26.0 software were used for data collation and statistical analysis. Descriptive analysis, chi-square test and Fisher's exact probability were used for statistical analysis.Results From 2016 to 2021, the prevalence rate of nosocomial infection was 1.89%-2.31%, and there was no statistical difference between years (χ2=1.133, P=0.951). The departments with the highest prevalence of nosocomial infection were mainly the Iintensive Care Unit, Department of Hematology, Department of Cardiac Surgery, Department of Rehabilitation Medicine, Department of Thoracic Surgery, etc. Except for 2018, the proportion of respiratory system in other years was more than 50%, and the proportion of Gram-negative bacteria was more than 70%. From 2016 to 2021, the utilization rate of antibiotics was 25.26%-37.45%, showing a downward trend, and the difference between years was statistically significant (χ2=150.784, P<0.001). The submission rate of pathogens culture for therapeutic use of antibiotics was 46.20%-56.75%, showing an overall upward trend, and there was a statistical difference between years (χ2=15.853, P=0.007).Conclusion The prevalence rate of nosocomial infection is low. At the same time, the reasonable use of antibiotics and the standardized submission of pathogen culture are developing well. However, the prevention and control of highrisk departments and places of nosocomial infection still need to be strengthened.
