The Dialysis Outcomes and Practice Patterns Study

The DOPPS is a prospective cohort study of hemodialysis practices based on the collection of observational longitudinal data for a random sample of patients from dialysis facilities in a representative and random sample of units in more than twenty countries.

The samples of patients in each facility, and sample of facilities in each country, are designed to provide a reliable picture of practices and outcomes in each facility, and in each geographic area. In view of differences in patient outcomes of mortality and morbidity by country and by dialysis unit, the study helps researchers:

  • Describe differences in practice patterns that correlate with differences in outcomes
  • Understanding the factors associated with patient outcomes will lead to improved patient care and lower mortality and morbidity  

Practice Patterns

Practice Patterns refer to the general range of treatment options faced by hemodialysis centers. Examples of practice patterns that may be related to outcomes include: staffing ratios and composition, size of unit, vascular access creation and salvage policies, dialysis prescription, and methods of delivering dialysis.


"Outcomes" refers to a variety of patient events that are associated with human and economic consequences. Important outcomes assessed in DOPPS include: mortality, hospital admission, vascular access failure, quality of life, and development of new medical conditions. 

DOPPS: Who We Are

The DOPPS is overseen by the DOPPS Steering Committee and investigators representing each of the DOPPS countries, and coordinated by the Arbor Research Collaborative for Health (Arbor Research).
