Pragmatic review of interventions to prevent catheter-associated urinary tract infections (CAUTIs) in adult inpatients

Abstract

Background: Urinary tract infections (UTIs) are one of the most common hospital-acquired complications. Insertion of a urinary catheter and the duration of catheterization are the main risk factors, with catheter-associated UTIs (CAUTIs) accounting for 70e80% of hospital-acquired UTIs. Guidance is available regarding the prevention of hospitalacquired CAUTIs; however, how best to operationalize this guidance remains a challenge. Aim: To map and summarize the peer-reviewed literature on model-of-care interventions for the prevention of CAUTIs in adult inpatients. Methods: PubMed, CINAHL and SCOPUS were searched for articles that reported UTI, CAUTI or urinary catheter outcomes. Articles were screened systematically, data were extracted systematically, and interventions were classified by intervention type. Findings: This review included 70 articles. Interventions were classified as single component (N¼19) or multi-component (N¼51). Single component interventions included: daily rounds or activities (N¼4), protocols and procedure changes (N¼6), reminders and order sets (N¼5), audit and feedback interventions (N¼3), and education with simulation (N¼1). Overall, daily catheter reviews and protocol and procedure changes demonstrated the most consistent effects on catheter and CAUTI outcomes. The components of multicomponent interventions were categorized to map common elements and identify novel ideas. Conclusion: A range of potential intervention options with evidence of a positive effect on catheter and CAUTI outcomes was identified. This is intended to provide a ‘menu’ of intervention options for local decision makers, enabling them to identify interventions that are relevant and feasible in their local setting.
