The Peritoneal Dialysis Outcomes and Practice Patterns Study

The Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) is designed to advance the understanding of optimal practices for PD patients worldwide.

The PDOPPS is a groundbreaking research initiative for understanding and advancing PD therapy. Continuing the DOPPS mission of improving outcomes and care for dialysis patients, the PDOPPS conducts clinical research to promote the appropriate use of PD, extend technique survival, and improve quality of life for PD patients.

Since its inception PDOPPS has been a mutual collaboration with the International Society for Peritoneal Dialysis (ISPD) around key areas of PD clinical practice guidelines and variation in PD practice.

The pilot study launched in October 2013, with longitudinal data collection starting in Canada and the United States in January 2014. The PDOPPS quickly expanded to Japan by late 2014. Australia, New Zealand, and the United Kingdom joined in 2015; Thailand joined the study in 2016. Across the six participating countries where data collection is underway, the study has already enrolled over 4000 patients across 180 participating study sites.


The PDOPPS is overseen by the PDOPPS International Steering Committee and investigators representing each of the PDOPPS countries, and coordinated by Arbor Research Collaborative for Health. Research is guided by these investigators, as well as working groups in different study areas.
