Feasibility of the COMFORT (COmplex Symptom Management Intervention FOR adulTs With Advanced Kidney Disease) Intervention for Adults With Advanced Kidney Disease and Their Informal Caregivers

Adults with advanced kidney disease may experience a substantial burden of physical and psychosocial symptoms, including fatigue, drowsiness, pruritus, pain, and restless legs. Multiple symptoms frequently occur at the same time and can negatively affect daily functioning, quality of life, and participation in everyday activities. Informal caregivers may also experience considerable burden, emotional strain, and uncertainty about how best to support the person with advanced kidney disease. Despite the high symptom burden, systematic symptom assessment and management are not consistently integrated into routine kidney care. Symptom management strategies may focus on individual symptoms rather than addressing multiple co-occurring symptoms and the broader needs and preferences of patients and their informal caregivers. Patients and caregivers may therefore benefit from a more structured approach that supports symptom recognition and management, shared decision-making, self-management, and caregiver involvement. The COMFORT Nursing Programme was established in 2023 to address these challenges. The programme has developed a structured, theory-informed, nurse-led intervention for symptom management in adults with advanced kidney disease. The COMFORT intervention comprises four core components: symptom management, shared decision-making, self-management support, and caregiver support. The intervention combines systematic symptom assessment using the Integrated Palliative care Outcome Scale-Renal (IPOS-Renal) with an evidence-based symptom management decision-support tool. Based on the symptoms, needs, and preferences identified by the participant, trained nephrology nurses support participants in prioritising symptoms, considering relevant symptom management strategies, participating in shared decisions, and strengthening their ability to manage symptoms in everyday life. Informal caregivers are involved and supported as part of the intervention. In this randomized feasibility study, adults with advanced kidney disease are allocated in a 1:1 ratio to usual care or usual care supplemented with the COMFORT intervention. The intervention is delivered over approximately 3 months and comprises two structured nurse-led consultations and one follow-up telephone consultation. The primary purpose of the study is to evaluate the feasibility and acceptability of the COMFORT intervention and the procedures required for a future definitive randomised controlled trial. The study will therefore evaluate recruitment and retention, intervention fidelity, acceptability among participants and nephrology nurses, completion and suitability of proposed outcome measures, and the feasibility of study procedures. Patient-reported and caregiver-reported measures will also be collected to evaluate their suitability for a future trial. The feasibility findings will be used to refine the COMFORT intervention and study procedures and to inform the design and conduct of a future multicentre randomised controlled trial evaluating the effectiveness of the COMFORT intervention.
