Home dialysis use has been on the rise, with greater absolute growth occurring with peritoneal dialysis (PD) and greater relative growth observed with home hemodialysis (HHD), according to data presented during the American Society of Nephrology’s Kidney Week 2021.
From 2016 to 2021, home dialysis use rose from 11.6% to 14.5%, Eric D. Weinhandl, PhD, MS, of Hennepin Healthcare Research Institute in Minneapolis, Minnesota, and colleagues reported. During that same period, HHD use increased from 1.57% to 2.31% and PD use increased from 10.0% to 12.2%.
Home dialysis use increased from 14.8% in 2016 to 20.0% in 2021 among patients with end-stage kidney disease (ESKD) duration of less than 2 years, with PD accounting for more than 90% of that use. Among patients with ESKD duration of 2 to 4 years, home dialysis use rose from 11.7% in 2016 to 13.7% in 2021.
Among patients with ESKD duration of 10 years or more, home dialysis use remained around 9%. HHD use reached a high of 3.65% in 2021, representing nearly 40% of home dialysis utilization, the investigators reported.
For the study, Dr Weinhandl’s team analyzed dialysis facility admission and discharge data from the End Stage Renal Disease Reporting System in May 2021. During the first epidemiologic week of each year from 2016 to 2021, they identified patients undergoing maintenance dialysis at the beginning of the week and identified the current dialysis modality for each patient.
