Objective To understand the prevalence of nosocomial infection in a hospital. Methods The hospitalized patients in this hospital were surveyed in the form of cross-sectional survey for 3 years in a row. The hospital bedside investigation and medical records of all hospitalized patients were collected on the survey day, and the questionnaire was filled in uniformly. Results The hospital infection rate was 4.70% in 3 years and 5.01% in hospital infection. In the three years, the top three infection rates in all departments were severe medical department (35.00%), laminar flow ward (31.58%) and hematology department (15.95%). The infected area constituted the lower respiratory tract (47.43% Urinary tract (15.81%) and hematological system (8.82%). The first three pathogens were Pseudomonas aeruginosa (13.90%), Escherichia coli (11.23%) and Staphylococcus aureus (9.63%). Conclusion The main departments of nosocomial infection are severe medical department, laminar flow ward and hematology. The main parts are respiratory tract, urinary tract and blood system. The pathogens are mostly Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus.
