Home hemodialysis (HHD), is the provision of hemodialysis to purify the blood of a person whose kidneys are not working normally, in their own home. People on home hemodialysis are followed by a nephrologist who writes the dialysis prescription and they rely on the support of a dialysis unit for back-up treatments and case management. Studies show that HHD improves patients' sense of well-being; the more they know about and control their own treatment the better they are likely to do on dialysis.
