Indwelling urinary catheters (IDCs) are a common invasive device in hospitalised patients. Their use is associated with increased risks of developing catheter associated urinary tract infections (CAUTI), and blood stream infections (BSI).
To examine the characteristics and outcomes of adult inpatients with an IDC inserted in hospital and identify risk factors for developing CAUTI and BSI.
We performed a retrospective observational study of 430 patients with IDC admitted to medical and surgical units of a leading (tertiary) hospital between Nov 2019 till April 2020. Multiple logistic regression analysis was performed to determine independent risk factors for developing urinary tract infection and blood stream infection.
The prevalence of CAUTI in our study was 7.4%. Results of multiple logistic regression indicated that with each day of IDC in situ, the likelihood of UTI development increased by 9% (OR 1.09; 95% CI 1.00 to 1.18; p = 0.03). Age, gender, and catheter reinsertion were not associated with UTI development.
Longer duration of IDC was associated with elevated risk of developing CAUTI. CAUTI rates were higher than some of those previously published. There was no statistical significance in frequency of CAUTI between medical and surgical patients. No statistically significant variables that contributed to the development of BSI were found. Interventions targeted at reducing catheter days should be used to improve CAUTI rates.
