BACKGROUND AND OBJECTIVES In the last 15 years in Canada, there have been less stringent guidelines for peritoneal dialysis (PD) adequacy, availability of novel PD solutions, and lower PD-related peritonitis rates. Effects of these changes on outcomes of incident patients treated with PD during this period are unknown. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Risk of PD technique failure and mortality were compared among three incident cohorts of PD patients who initiated dialysis during the following periods: 1995-2000, 2001-2005, and 2006-2009. A multivariable model was used to evaluate time to PD technique failure using inverse probability of treatment and censoring weights accounting for changing survival and transplantation rates. RESULTS Between 1995 and 2009,13,120 incident adult PD patients were identified from the Canadian Organ Replacement Register. Compared with the 1995-2000 cohort (n=5183), the risk of PD technique failure was lower among patients between 2001 and 2005 (n=4316) but similar among incident patients between 2006 and 2009 (n=3621). Cause-specific PD technique failure revealed no difference in PD peritonitis-related technique failure over time. PD technique failure due to inadequate PD was initially higher in the 2001-2005 cohort but lower in the 2006-2009 cohort compared with the 1995-2000 cohort. Relative to incident patients between 1995 and 2000, adjusted mortality was lower among incident patients between 2001 and 2005 and 2006 and 2009. CONCLUSIONS Survival on PD continues to improve with only modest changes in PD technique failure. Peritonitis remains an ongoing and modifiable source of PD technique failure.

Geographic and facility-level variation in the use of peritoneal dialysis in Canada: a cohort study.

BACKGROUND Peritoneal dialysis is associated with similar survival and similar improvement in quality of life and is less costly compared with in-centre hemodialysis. We examined facility and geographic variation in the use of peritoneal dialysis in Canada. METHODS We analyzed data from the Canadian Organ Replacement Register for the period January 2001 to December 2010. We identified patient...

A Comparative Study on Using Coiled Versus Straight Swan-Neck Tenckhoff Catheters in Patients Undergoing Peritoneal Dialysis

The key to successful long-term peritoneal dialysis (PD) is permanent and safe access to peritoneal cavity. The two most commonly used Tenckoff catheters for PD are the straight and coiled catheters. The present study was undertaken to assess the catheter survival, catheter associated infections, and all cause mortality and to compare the straight with coiled catheters in PD. During April 1997-...

The Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS): Unifying Efforts to Inform Practice and Improve Global Outcomes in Peritoneal Dialysis.

UNLABELLED ♦ BACKGROUND Extending technique survival on peritoneal dialysis (PD) remains a major challenge in optimizing outcomes for PD patients while increasing PD utilization. The primary objective of the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) is to identify modifiable practices associated with improvements in PD technique and patient survival. In collaboration w...

Propensity-matched mortality comparison of incident hemodialysis and peritoneal dialysis patients.

Contemporary comparisons of mortality in matched hemodialysis and peritoneal dialysis patients are lacking. We aimed to compare survival of incident hemodialysis and peritoneal dialysis patients by intention-to-treat analysis in a matched-pair cohort and in subsets defined by age, cardiovascular disease, and diabetes. We matched 6337 patient pairs from a retrospective cohort of 98,875 adults wh...

BACKGROUND AND OBJECTIVES Home dialysis is often recognized as a first-choice therapy for patients initiating dialysis. However, studies comparing clinical outcomes between peritoneal dialysis and home hemodialysis have been very limited. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS This Australia and New Zealand Dialysis and Transplantation Registry study assessed all Australian and New Zea...
