Abstract:
Objective To understand the epidemiological characteristics and influencing factors of nosocomial infection in Bengbu area, and to provide basis for formulating effective prevention and control measures of nosocomial infection.
Methods A bedside survey was conducted to investigate the prevalence of nosocomial infection among all patients in 12 public hospitals in Bengbu from 0:00 to 24:00 on December 24, 2021. The incidence of nosocomial infection, infection site, infection pathogens, the use of antibiotics and the influencing factors of nosocomial infection were analyzed.
Results A total of 5 281 hospitalized patients were investigated in this study. The prevalence rate of nosocomial infection was 1.14%, the most common infection site was the respiratory system (55%), and the department with the highest incidence of nosocomial infection was ICU (9.0%). Escherichia coli and Staphylococcus aureus accounted for 8.3% of the infected bacteria, and the use rate of antibiotics in this survey was 38.6%. Multivariate logistic regression analysis showed that extreme age, solid tumor and coma were the independent risk factors of nosocomial infection in the internal factors of patients (P ＜ 0.01 to P ＜ 0.05), while the external factors such as arteriovenous intubation, urinary tract intubation, ventilator use, three types of surgical incision and the risk of nosocomial infection were significantly increased (P ＜ 0.01 to P ＜ 0.05)).
Conclusion The main influencing factors of nosocomial infection are extreme age, solid tumor, coma, arteriovenous intubation, urinary tract intubation, use of ventilator and three types of surgical incision. Identifying risk factors of nosocomial infection is helpful to identify high-risk groups and factors, and formulate targeted interventions to reduce the risk of nosocomial infection.
