Abstract

Objective: To determine the incidence and predictors of hospital acquired catheter associated urinary tract infections among catheterized patients admitted at Kenyatta National Hospital Critical Care Unit
Study Design: Prospective Cohort Study
Setting: Kenyatta National Hospital Critical Care Unit
Subjects: the study population was two hundred and thirty-eight patients admitted in the critical care unit between January 2019 and January 2020 and were put on urinary catheter
Main Outcome Measures: Incidence of hospital acquired urinary tract infection, patient level and hospital level risk factors associated with catheter associated urinary tract infections.
Results: the incidence density of hospital acquired catheter associated urinary tract infection was 32 per 1000 Catheter-days in the critical care unit. The cumulative incidence was 28.7%. Patients having other comorbidities had a higher risk to acquire catheter associated urinary tract infection; risk ratio of 1.669. Failure to observe aseptic techniques during emptying of the urine bag had a higher risk to acquire catheter associated urinary tract infection; risk ratio of 3.392. Failure to secure the urinary catheter on the patient’s thigh had a higher risk to acquire catheter associated urinary tract infection; risk ratio of 1.836.
Conclusion: the incidence of intensive care acquired catheter associated urinary tract infection at the critical care unit is relatively high compared to other jurisdictions. The risk factors associated with the high incidence of the urinary tract infection are comorbidities, failure to observe aseptic techniques during emptying of the urine bag and failure to secure the urinary catheter on the patient’s thigh.
