Background: Community-based urinary catheter-associated complications contribute to avoidable, costly hospital presentations. To minimise catheter-associated complications and improve the quality of life of patients living in the community, it is essential to improve catheter self-management through increasing patients��� and caregivers��� knowledge and self-efficacy. Aim: To co-design, develop and evaluate a bundle-of-care intervention to improve catheter self-management, reduce catheter-associated complications, and improved quality of life. Design: Mixed methods design underpinned by the principles of Appreciative Inquiry, micro- and spaced-learning pedagogies. Methods: A co-designed care bundle will be developed, to support both patients and nurses in improving catheter care in both acute and community settings. Intervention bundles for patients will be delivered using ���GoShare Healthcare��� and for nurses, using QStream. The underpinning pedagogical approaches of these two digital platforms focus on increasing knowledge retention and improving patient health outcomes. A process evaluation of the intervention will be undertaken using data collected from surveys, electronic medical record audits, and participant interviews. The primary outcome is improved catheter self-management, and secondary outcomes are increased self-efficacy and patients��� knowledge of catheter self-management. Discussion: The IQ-IDC study applies a two-pronged approach to co-design a bundle-of-care intervention that addresses important gaps in current catheter management. This study will contribute to new knowledge on effective implementation strategies to optimise self-management in urinary catheter care.
