Abstract

Background: Non-dialytic conservative care (CC) has been proposed as a viable alternative to maintenance dialysis for selected older patients to treat end-stage kidney disease (ESKD). This systematic review compares both treatment pathways on health-related quality of life (HRQoL) and symptoms, which are major outcomes for patients and clinicians when deciding on preferred treatment.

Methods: We searched PubMed, Embase, Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL) Plus and PsycINFO from inception to 1 October 2019 for studies comparing patient-reported HRQoL outcomes or symptoms between patients who chose either CC or dialysis for ESKD.

Results: Eleven observational cohort studies were identified comprising 1718 patients overall. There were no randomized controlled trials. Studies were susceptible to selection bias and confounding. In most studies, patients who chose CC were older and had more comorbidities and worse functional status than patients who chose dialysis. Results were broadly consistent across studies, despite considerable clinical and methodological heterogeneity. Patient-reported physical health outcomes and symptoms appeared to be worse in patients who chose CC compared with patients who chose dialysis but had not yet started, but similar compared with patients on dialysis. Mental health outcomes were similar between patients who chose CC or dialysis, including before and after dialysis start. In patients who chose dialysis, the burden of kidney disease and impact on daily life increased after dialysis start.

Conclusions: The available data, while heterogeneous, suggest that in selected older patients, CC has the potential to achieve similar HRQoL and symptoms compared with a dialysis pathway. High-quality prospective studies are needed to confirm these provisional findings.
