Peritoneal Dialysis Utilization and Outcome: What are we Facing?

Penetration of peritoneal dialysis (PD) varies tremendously across the world. It ranges from about 80% in Hong Kong and Mexico to just a few percentage points in the United States, Japan, and Germany. While PD is growing in China, India, and some Eastern European and South American countries, it is declining in many European and North American countries. In terms of outcomes, the survival of PD patients is generally comparable to that of hemodialysis (HD) patients and better than that of HD patients during the first few years on dialysis. According to the U.S. Renal Data System, survival of patients on PD has been improving faster than that of patients on HD. In terms of cost, PD is usually cheaper than HD. Hence, declining PD utilization is unjustified. Work is required to identify and overcome negative factors such as physician bias, unfair medical reimbursement systems, and poor patient education.
