title: The dialysis outcomes and practice patterns study phase 5 in the Gulf Cooperation Council countries: Design and study methods.
abstract: The Dialysis Outcomes and Practice Patterns Study (DOPPS) is an international prospective cohort study of the relationships between hemodialysis (HD) care practices and HD patient outcomes. The DOPPS began in 1996, in the United States, and has since expanded to 21 countries, collecting detailed data from >75,000 HD patients, with >200 scientific publications, focused on describing HD practices associated with improved HD patient outcomes. The goal of DOPPS is to help HD patients "live better and live longer." Starting in 2012, the DOPPS was able to expand to all six of the Gulf Cooperation Council (GCC) countries, namely, Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and the United Arab Emirates. The DOPPS study design consists of selecting HD facilities for study participation in each country to represent the different types of HD facilities and geographic regions within each GCC country. Within each study site, HD patients were randomly selected for detailed data collection to represent the HD practices within each participating HD facility. Altogether, 41 HD facilities have participated in the GCC-DOPPS Phase 5 study including 20 facilities from Saudi Arabia, nine from the United Arab Emirates, four each from Kuwait and Oman, two from Qatar, and one from Bahrain. Herein, we provide a detailed description of the study design and methods, data collection, study management, scientific investigator oversight and guidance, and study governance and support for the GCCDOPPS Phase 5 study.
