Long-term outcome in continuous ambulatory peritoneal dialysis: a 10-year-survey by the Italian Cooperative Peritoneal Dialysis Study Group.

Over a 10-year period, 1,990 end-stage renal disease patients in 30 centers were treated with continuous ambulatory peritoneal dialysis by the Italian Cooperative Peritoneal Dialysis Study Group. At the start of treatment, patients had an average age of 58.4 years, with a 66% prevalence of one or more clinical risk factors for premature death. Patient survival was 51% and 33% at 4 and 8 years on continuous ambulatory peritoneal dialysis, respectively, and technique survival was 62% and 48%, respectively. Occurrences of peritonitis progressively reduced until they reached an incidence of 0.50 episodes/yr in the last 5 years (1985 to 1989). Hernias and catheter-related problems did not influence the dropout rates. These Italian Cooperative Peritoneal Dialysis Study Group results demonstrate that continuous ambulatory peritoneal dialysis is a viable dialysis technique for long-term treatment of chronic renal failure and that it is an effective alternative to hemodialysis, especially for older and high-risk patients.
