Abstract:
Self-management of long-term urinary catheters can be challenging for patients, and recurrent catheter blockages may cause concern among patients, carers and healthcare professionals. Catheter blockages are a significant challenge for nurses practising in community settings, because frequent and unplanned catheter changes can be costly to healthcare services in terms of time and resources. This article details evidence-based recommendations for the assessment and diagnosis of catheter blockages, as well as the identification of risk factors. It also explains the interventions that can be used to prevent and manage catheter blockages and describes the role of the nurse in supporting patients with a long-term catheter in situ in community settings.
