Abstract:

Objective

To investigate the current status of catheter-associated urinary tract infections (CAUTI) in hospitalized patients in the geriatrics department, and analyze the risk factors for the occurrence of CAUTI.

Methods

Through the Xinglin Hospital Infection Monitoring System,data from 210 patients with urinary catheters in the geriatrics department of Suqian hospital from 2019 to 2023 were retrospectively collected.The patients were divided into infection group (n=10) and noninfection group (n=200) based on the occurrence of CAUTI.Analyze the catheter utilization rate, CAUTI incidence, and distribution of pathogenic microorganisms.Univariate analysis was employed to compare the relevant data between the two groups, and significant variables were included in multivariate logistic regression analysis to predict the risk factors for CAUTI.

Results

The urinary catheter utilization rate among hospitalized patients in the geriatrics department was 6.02%, with a CAUTI incidence rate of 4.36‰.CAUTI accounted for 16.39% of all infections and 47.62% of urinary tract infections.A total of 10 pathogenic strains were identified, including 6 fungal strains and 4 Gram-negative bacterial strains.Logistic regression analysis revealed that the use of glucocorticoids for ≥3 days was an independent risk factor for the occurrence of CAUTI (OR=5.173, 95%CI=1.007-26.561, P < 0.05).

Conclusion

The incidence of CAUTI in the geriatrics department of the hospital is high and shows an upward trend,with fungal infections being predominant.Patients using glucocorticoids for ≥3 days require particular vigilance for the occurrence of CAUTI.
