Importance Most children with end-stage kidney disease (ESKD) are treated with dialysis prior to transplant.It is not known whether their outcomes have changed in recent years. ObjectiveTo determine if all-cause, cardiovascular, and infection-related mortality rates for children and adolescents beginning dialysis improved between 1990 and 2010.Design, Setting, and Participants Retrospective cohort study of patients younger than 21 years initially treated with dialysis for ESKD, recorded in the United States Renal Data System between 1990 and 2010.Children with a prior kidney transplant were excluded.We used Cox proportional hazard models to estimate the hazard ratios (HRs) for mortality associated with a 5-year increment in year of ESKD treatment initiation.Primary analyses censored observation at kidney transplant. Main Outcomes and Measures All-cause, cardiovascular, and infection-related mortality.Results A total of 23 401 children and adolescents who initiated ESKD treatment with dialysis at younger than 21 years between 1990 and 2010 were identified.Crude mortality rates during dialysis treatment were higher among children younger than 5 years at the start of dialysis compared with those who were 5 years and older.Mortality rates for both children and adolescents being treated for ESKD with dialysis decreased significantly between 1990 and 2010.
