The Dialysis Outcomes and Practice Patterns Study (DOPPS) Program continues to expand into new countries and study areas. We are pleased to provide you with the following updates on our research. For more information and future updates, please visit DOPPS.org.

DOPPS

The DOPPS collects and analyzes data on in-center hemodialysis practices in 21 countries. This study has been ongoing since 1996 and has resulted in nearly 200 publications.

Russia and Turkey are the most recent countries added to the DOPPS. Data collection began in both countries in September 2013. Centers participating in the DOPPS in Russia represent 90% of dialysis patients there; the dialysis centers participating in the DOPPS in Turkey represent more than 95% of that country's hemodialysis population.

PDOPPS

Built on the model of the DOPPS, the Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) is designed to reveal optimal practices for peritoneal dialysis patients worldwide. The PDOPPS pilot study launched in Canada in October 2013. Pilot studies are also slated to begin soon in Japan, the United Kingdom, and the United States. Funding for the PDOPPS in Australia has been secured and a mid-2014 launch is planned.

CKDopps

The Chronic Kidney Disease Outcomes and Practice Patterns Study (CKDopps) is also built on the model of the original DOPPS. This facility-based cohort study of practices treating chronic kidney disease is based on observing longitudinal prospective and retrospective data. After the successful conclusion of pilot studies in France and Brazil, as well as the analysis of retrospective data from Germany, CKDopps has now launched in all three countries. CKDopps data collection is planned to begin in the United States in early 2014.
