Dialysis takes hours of kidney disease patients' time several days a week, so why not do it at night while sleeping? Overnight dialysis is more convenient for some patients and offers significant benefits over shorter daytime treatments, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society of Nephrology (CJASN). The findings indicate that overnight dialysis is a viable alternative for patients with irreversible kidney disease, particularly in dialysis clinics where there are constraints on time and resources.
