Age is not a contraindication to home-based dialysis – Quality-of-Life outcomes favour older patients on peritoneal dialysis regimes relative to younger patients

Authors


Abstract

Aim

To compare Quality of Life, anxiety and depression between older (≥65 years) and younger (<65 years) patients across automated peritoneal dialysis and continuous ambulatory peritoneal dialysis.

Background

There is a lack of studies as to whether the different peritoneal dialysis modalities confer similar outcomes in older and younger patients.

Design

Cross-sectional.

Methods

A total of 201 patients completed the Kidney Disease Quality of Life Short-Form, World Health Organization Quality of Life Instrument, Short Form and Hospital Anxiety and Depression Scale. Comorbidity and biochemical values were abstracted from medical records.

Results

Older patients reported significantly better quality of life than younger patients in the Kidney Disease Quality of Life Short-Form effects of kidney disease and patient satisfaction and the World Health Organization Quality of Life Instrument overall Quality-of-Life/health despite worse clinical profile. Quality of life outcomes were comparable between automated peritoneal dialysis and continuous ambulatory peritoneal dialysis with the exception of the Kidney Disease Quality of Life Short-Form symptoms in favour of automated peritoneal dialysis. Levels of anxiety and depression were equivalent for older and younger patients across peritoneal dialysis modalities. The observed quality-of-life advantages for older patients persisted after case-mix adjustments and extended to more quality-of-life domains and depression and anxiety.

Conclusion

Our findings of superior quality of life in patients aged ≥ 65 support the expansion of peritoneal dialysis use in older patients. Patients across different age groups should be given non-biased information about both peritoneal dialysis modalities and individual preferences should be elicited and carefully considered by healthcare providers.
