Sundhedserhvervet kateterrelateret urinvejsinfektioner på hospitalet En databaseret undersøgelse

Abstract

Background: Indwelling urinary catheters (IUCs) increase the risk of healthcare-associated urinary tract infections. Healthcare-associated catheter-related urinary tract infections usually cause additional complications and discomfort for patients, highlighting the need for careful and appropriate use of IUCs and monitoring of the use and related urinary tract infections. Research question: What was the prevalence of healthcare-associated urinary tract infections among patients > 50 years of age and with IUCs at Aarhus University Hospital in 2024? Which factors increase the risk of developing catheter-related urinary tract infections and which risk factors can be targeted for interventions? Methods: A data-driven cohort study was conducted comprising patients aged over 50 years with an IUC at Aarhus University Hospital in 2024. Patient data were extracted from the electronic patient record system and data on health care-associated urinary tract infections were obtained from the Danish national HAIBA database. The variables analyzed in relation to catheter-related urinary tract infections included sex, age, BMI, and catheter dwell time. Results: The cohort comprised 8305 patients over 50 years of age, all with an IUC. In total, 243 patients (2.9%) developed a catheter-related healthcare-associated urinary tract infection. A significantly higher incidence was detected among females compared to males and among patients over 70 years of age. Catheter dwell time was significantly longer in the group that developed catheter-related urinary tract infections compared to those who did not. BMI >30 did not increase the risk of these infections. Conclusion: In the present study significant risk factors for healthcare-associated urinary tract infections in patients with IUCs were female sex, age over 70 years and long catheter dwell time. Perspective: The results highlight that non-modifiable risk factors such as gender and age should be taken into account when deciding on the use of IUCs and IUCs should be used for the shortest possible time.
