Reducing catheter-associated urinary tract infection in high dependency unit: an eighteen-month quality improvement intervention study period
Abstract
Summary Background The urinary catheter usually leads to a catheter-associated urinary tract infection (CAUTI) contributing to further morbidity and mortality. There is very limited data on the CAUTI incidence rate in high-dependency units (HDUs) in the Kingdom of Saudi Arabia. The institutional CAUTI incidence rate in HDU was six times higher compared to the United States National Healthcare Safety Network (US–NHSN) in 2021. Objective To reduce 50% CAUTI incidence rate by the end of 2022. Method A prospective study was conducted in tertiary HDU from January 2022 to June 2023. A gap analysis was assessed between the hospital practices and the Society Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA/IDSA) basic recommendations. The Kotter and Rathgebers' changing behavior model was applied at the beginning of the project. Formal education and prevention of CAUTI were applied using the National Strategy Model. Surveillance and statistical data analysis were carried out using US-NHSN guidelines. Results The overall CAUTI incidence rate declined from 7.07- to 3.57/1000 urinary catheter days despite of significant increase in the utilization ratio from 0.79 to 0.94 (P value 0.0001). The compliance rate of the bundle CAUTI prevention was improved and sustained above 90%. A CAUTI incidence rate reduction was observed following the combination of the changing behavior and SHEA/IDSA of CAUTI prevention models over 18 months. Conclusion We assumed the…
