Quality of life and emotional distress between patients on peritoneal dialysis versus community-based hemodialysis

Abstract

Purpose: Patient-reported outcomes are important endpoints to evaluate new models of renal delivery. This is the first study to compare Quality of Life (QOL) and emotional adjustment outcomes between patients on community-based hemodialysis (HD) and those on peritoneal dialysis (PD).

Methods: Data were collected between 2009 and 2011 from a cross-sectional sample of 232 HD patients and 201 PD patients recruited through community dialysis centers and outpatient PD clinics in Singapore. Participants completed the Hospital Anxiety and Depression Scale, World Health Organization Quality of Life Brief and the Short form for the Kidney Disease Quality of Life. Measures of ESRD severity, comorbidity and biochemistry were also collected.

Results: Physical and emotional QOL impairments were noted for both dialysis groups. Case-mix-adjusted comparisons indicated higher symptoms of depression (p = 0.027), and poorer physical health yet higher satisfaction with care (p = 0.001) in PD relative to community-based HD.

Conclusions: Peritoneal dialysis regimes offer flexibility and autonomy under the support of PD teams. Although outcomes for most QOL domains measured were equivalent, PD patients are more satisfied with care but are at risk for emotional distress and provide poor ratings of physical health. Further research is needed to explore the expansion of standards of care to address psychosocial needs in PD populations.
