The DOPPS is a collection of studies designed to identify best practices for treating patients with chronic kidney failure. Started as a hemodialysis study in 1996, the DOPPS now tracks over 70,000 patients on hemodialysis, peritoneal dialysis, and with chronic kidney disease, in over 20 countries. By observing patients over time, and correlating practices and outcomes in different medical settings around the world, the DOPPS helps researchers identify practices and other modifiable characteristics that improve patient lives.
The DOPPS is longitudinal and collects information on hemodialysis centers and patients in more than twenty countries using a common protocol over time. With a focus on the full range of unit practice patterns that may relate to clinically important outcomes, the outcomes measures will be adjusted for patient comorbidities and adjusted to a greater extent than previously possible in other studies.
The international scope of the DOPPS provides greater variability in practice patterns and outcomes than can be observed in one country. This increased variation along with the study's large sample size leads to a greatly enhanced ability to understand the relationships between various treatment effects and patient outcomes.
The efforts of the DOPPS to obtain a representative, random sample of facilities and patients within each country allows for practice patterns within a participating country to be described.
