Risk factors of nosocomial infection in patients with an indwelling catheter
Objective To analyze the risk factors and pathogenic bacteria of nosocomial infection in patients with indwelling catheterization,so as to provide reference for reducing the incidence of such infection in patients with indwelling catheterization.Methods 690 hospitalized patients with nose-acquired infection were selected from a Grade A hospital in Gansu Province from January to December 2021,and 690 hospitalized patients without nose-acquired infection were matched.340 patients with indwelling catheterization were selected as the study objects.The risk factors of nosocomial infection were analyzed by one-way ANOVA and binary Logistic regression.Results There were 238 patients(34.49%)with nosocomial infection,more than the number of original urine patients[102 cases(14.78%)],and the difference was statistically significant(χ2=72.185,P<0.05).The results of single factor analysis showed that 18 factors,such as catheter placement time,central vein intubation time,ventilator use time,hospital stay time and fever time,were related to nosocomial infection in patients with indentation catheterization.The results of multivariate analysis showed that underly-ing disease,invasive procedure(endoscopy),organ transplantation,use of blood products,adverse operation events,number of antibiotics and length of stay were independent risk factors for nosocomial infection in pa-tients with induration catheterization(P<0.05).The main pathogenic bacteria was Acinetobacter baumannii in gram-negative bacteria(17.30%).Conclusion Many risk factors are related to nosocomial infection in patients with indwelling catheterization.In clinical practice,medical staff should pay attention to the risks of such in-fection,and formulate and implement corresponding prevention and control measures.
