Diabetes is a common problem which causes multiple complications including chronic kidney disease. This project will evaluate the health status of patients with Type 1 and Type 2 diabetes who develop end-stage kidney disease (ESKD) and compare their survival over time. It is unknown whether the survival of patients with Type 1 Diabetes differs from the survival of patients with Type 2 diabetes who start dialysis treatment. It is also unknown whether differences exist in the burden of illness at the start of dialysis, differences in the quality of care they received prior to dialysis and differences in the extent of treatment following follow-up, all of which may contribute to survival differences. Our study will be the first to compare Type 1 and Type 2 diabetes and survival patterns using information from the world’s largest kidney registry: The United States Renal Data System. This project is important as it will improve our understanding of the care and outcomes of these high-risk patients in a nationally representative cohort.
