Peritoneal Dialysis Outcomes and Practice Patterns Study
The Peritoneal Dialysis Outcomes and Practice Patterns Study (PDOPPS) is a prospective, observational cohort study of peritoneal dialysis (PD) subjects and facilities in several countries. The estimated study duration is 3 years. PDOPPS will employ the research design and methods used in all prior phases of the Dialysis Outcomes and Practice Pattern Study (DOPPS). The study design and study instruments are shared across all participants. Dialysis facilities in PDOPPS are randomly selected in each country from a complete list of PD facilities treating more than 15 PD patients; facilities are stratified by characteristics such as geographic region and unit type. A random sample of subjects, averaging between 12 and 30 patients per study site, will be drawn from each participating facility census. Detailed information on selected patients, facility protocols, and physician practices are obtained by questionnaires that are completed at various points throughout the study. These data will be analyzed at both the subject- and facility-levels, thereby providing the opportunity to monitor practice and policy changes and their effects on clinical outcomes such as time on PD therapy, mortality, hospitalization, and quality of life. This is an observational study with no intervention.
