Survival and analysis of predictors of mortality in patients undergoing replacement renal therapy: a 20-year cohort.

Background: optimal management of end-stage renal disease (ESRD) in hemodialysis (HD) patients should be more studied because it is a serious risk factor for mortality, being considered an unquestionable global priority.

Methods: we performed a retrospective cohort study from the Nephrology Service in Brazil evaluating the survival of patients with ESRD in HD during 20 years. Kaplan-Meier method with the Log-Rank and Cox's proportional hazards model explored the association between survival time and demographic factors, quality of treatment and laboratory values.
