Since the emergence of home peritoneal dialysis as an alternative to in-center hemodialysis for chronic renal replacement therapy in the late 1970s, the percentage of dialysis patients on PD has continued to decrease each year. There have been a growing concern and research on patient and technique survival of peritoneal dialysis versus hemodialysis to find influential factors for better clinical outcomes. Meanwhile, technique failure rates were significantly higher in small centers treating less than twenty five PD patients. And there was a result for better technique survival after the second year, among the patients trained at the BREC(Baxter Renal Education Center). Better technique survival in large centers can be assumed with not only their more experience with patient management but also their educational infrastructure compared to small-sized centers.
