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 (COMFORT)
Feasibility of the COMFORT Intervention: A Randomised Feasibility Study of a Tailored Nurse-Led Symptom Management Intervention for Adults With Advanced Kidney Disease and Their Informal Caregivers
The purpose of this randomized feasibility study is to examine whether the COMFORT intervention is feasible and acceptable for adults with advanced kidney disease and their informal caregivers.
People with advanced kidney disease often experience several symptoms, such as fatigue, itching, pain, and sleep-related problems. These symptoms can affect daily life and quality of life and may also place a burden on family members and other informal caregivers. The COMFORT intervention is a nurse-led programme designed to help patients and their informal caregivers recognise and manage symptoms.
A total of 56 adults with advanced kidney disease will be randomly assigned to one of two groups. One group will receive usual care. The other group will receive usual care plus the COMFORT intervention over approximately 3 months. The intervention includes systematic assessment of symptoms, a symptom management decision-support tool, shared decision-making, support for self-management, and involvement and support of informal caregivers. It is delivered by trained nephrology nurses through two structured consultations and one follow-up telephone consultation.
The study will examine whether patients can be successfully recruited and retained, whether the intervention can be delivered as planned, whether patients, informal caregivers, and nurses find the intervention acceptable, and whether the study procedures and questionnaires are suitable for use in a future larger trial. The study is not designed to determine whether the COMFORT intervention is clinically effective.

Descrizione dettagliata
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.
