Abstract
Home haemodialysis (HHD) is utilized significantly less often than facility HD globally with few exceptions, despite being associated with improved survival and better quality of life. Previously HHD was exclusively offered to younger patients with a few comorbidities. However, with the increasing burden of end-stage kidney disease (ESKD) alongside an ageing population, increasing numbers of older patients are being treated with HHD. This study aims to re-evaluate survival and related outcomes in the context of this epidemiological shift. A matched cohort design was used to compare all-cause mortality, transplantation, average biochemical values and graft survival 6 months post-transplant between HHD and facility HD patients. A total of 181 HHD patients from a major hospital network were included with 413 facility HD patients from the Australia and New Zealand Dialysis and Transplant Registry matched by age, gender and cause of ESKD. Survival analysis and competing risks analysis (for transplantation) were performed. After adjusting for body mass index, smoking status, racial group and comorbidities, HHD was associated with a significantly reduced risk of death compared with facility HD patients [hazard ratio 0.47 (95% confidence interval 0.30-0.74)]. Transplantation rates were comparable, with high rates of graft survival at 6 months in both groups. Haemoglobin, calcium and parathyroid hormone levels did not vary significantly. However, HHD patients had significantly lower phosphate levels. In this study, improved survival outcomes were observed in patients on home compared with facility dialysis, with comparable rates of transplantation, graft survival and biochemical control.
