The Dialysis Outcomes and Practice Patterns (DOPPS) Program

The mission of the DOPPS Program is to improve the patient experience of individuals with kidney disease by identifying links between international variations in clinical practices and outcomes. The studies within the DOPPS Program are designed to identify best practices for treating patients. Started as a hemodialysis study in 1996, the DOPPS now tracks over 70,000 patients from over 20 countries who are treated with hemodialysis or peritoneal dialysis, or who have chronic kidney disease. By observing patients over time and correlating practices and outcomes in different medical settings around the world, the DOPPS helps researchers and care providers identify clinical practices and other modifiable characteristics that improve patient lives.

Hemodialysis: DOPPS

The DOPPS is a prospective cohort study of hemodialysis practices based on the collection of observational longitudinal data for a sample of patients and dialysis facilities in twenty countries.  The study helps researchers describe differences in practice patterns that correlate with differences in patient outcomes and understand the factors associated with these outcomes that will lead to improved patient care and lower mortality and morbidity. Over it’s more than 20-year history, the DOPPS has informed dialysis practice and policy in numerous areas, including vascular access, dialysis session length, quality of life, and the patient experience.

Peritoneal Dialysis: PDOPPS

The Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) is is a groundbreaking research initiative for understanding and advancing optimal practices for PD therapy worldwide. The PDOPPS conducts clinical research to promote the appropriate use of PD, extend technique survival, and improve quality of life for PD patients. In the first phase of PDOPPS, 7629 patients from 215 dialysis facilities in seven participating countries participated (Australia, Canada, Japan, New Zealand, Thailand, the United Kingdom, and the US). Since its inception, PDOPPS has been a mutual collaboration with the International Society for Peritoneal Dialysis (ISPD); this includes the ongoing launch of the second phase of PDOPPS, extending data collection to Colombia and South Korea and focusing on novel areas of research.

Chronic Kidney Disease: CKDopps

The Chronic Kidney Disease Outcomes and Practice Patterns Study (CKDopps) examines treatment variation and practices associated with the best outcomes for patients with advanced CKD. We find reliable evidence about the impact of treatment options on patient survival, quality of life, delay/avoidance of dialysis, and cost analysis related to treatment. The overall goal is to develop an evidence base for the effective treatment of advanced CKD, thereby improving care and outcomes for future patients. The project research yields insightful, actionable findings relevant to patients, clinicians, policy makers, and other stakeholders regarding best treatment practices. The CKDopps team includes experts from Brazil, France, Germany, Japan, and the US. Read more about CKDopps...

DOPPS Practice Manager: DPM

The DOPPS Practice Monitor is a free tool that shares timely findings from our studies: data are updated every four months, with only a three-to-four month lag between data collection and web posting. We provide dialysis data from a sample of over 11,000 patients in more than 200 US hemodialysis facilities. DPM data can be readily used through over 1500 regularly updated charts, figures, and data tables, research papers describing the DPM methods and findings, and recorded presentations of trends. See how DPM data can assist you...

Ancillary Studies

The Dialysis Outcomes and Practice Patterns Study (DOPPS) has a long history of successful collaborations with investigators outside of Arbor Research Collaborative for Health. We are committed to collaboration with external investigators to maximize the scientific value of the wealth of data made possible by all the participating facilities and patients. To increase our potential impact on direct clinical care, our portfolio often includes focused ancillary studies.
