Choice of dialysis modality among patients initiating dialysis: results of the peridialysis study
Abstract Background In patients with end-stage kidney disease (ESKD), home dialysis offers socioeconomic and health benefits compared to in-centre dialysis but is generally underutilized. We hypothesized that pre-dialysis course and institutional factors affect choice of dialysis modality after dialysis initiation (DI). Methods The Peridialysis study is a multinational, multicentre prospective observational study assessing the causes and timing of DI and consequences of suboptimal DI. Clinical and biochemical data, details of the pre-dialytic course, reasons for DI and causes of choice of dialysis modality were registered. Results Among 1587 included patients, 516 (32.5%) were judged unsuitable for home dialysis due to contraindications (384; 24.2%) or no assessment (106; 6.7%; mainly due to late referral and/or suboptimal DI) or death (26; 1.6%). High age, comorbidity, late referral, suboptimal DI, acute illness, and rapid loss of renal function associated with unsuitability. Of the remaining 1071 patients, 700 (65.4%) chose peritoneal dialysis (61.7%) or home haemodialysis (3.6%), while 371 (34.6%) chose in-centre HD. Somatic differences between patients choosing home dialysis and in-centre dialysis were minor; factors linked to choice of in-centre dialysis were late referral, suboptimal DI, acute illness and absence of a “home dialysis first” institutional policy. Conclusions Given a personal choice with shared decision making, 65.4% of ESKD patients choose home dialysis. Our data indicate that the incidence of home dialysis potentially could be further increased to reducing the incidence of late referral and unplanned DI, and, in acutely ill patients, by implementing an educational program after improvement of their clinical condition.
