Peritoneal dialysis is less costly than in-center hemodialysis and offers equal mortality risk and improved quality of life. Still, such therapy for patients with end-stage renal disease has not been widely embraced in the United States and other developed countries.
Worldwide, an estimated 1.8 million patients receive some form of dialysis, with only about 11% undergoing peritoneal dialysis. In the United States, of more than 390 000 patients who received dialysis in 2010, only about 7% were treated with peritoneal dialysis—down from peak usage in 1995, when 14.4% of US dialysis use was peritoneal.
