Relationship between biochemical indices in hemodialysis patients and mortality; survival analysis

Introduction: people with chronic kidney disease (ckd) undergoing hemodialysis pay high costs and suffer from complications like premature death.objectives: this study was conducted to determine the relationship of various blood parameters in hemodialysis with premature death.patients and methods: in this cross-sectional study, 90 hemodialysis patients were enrolled using consensus sampling method. demographic characteristics were recorded. additionally, serum level of ferritin and biochemical parameters were assessed. the log-rank test for survival probability and cox proportional-hazards model were applied to examine the correlation between assessed factors and the risk of premature death.results: the results of log-rank test showed that only coronary artery disease (cad) and serum ferritin have a role in predicting survival probability, since the survival rate of the people with and without cad was about 25 months (with a confidence interval of 37.60 - 12.36) and 46 months (with a confidence interval of 51.63-40.36) (p = 0.041) respectively.conclusion: it seems that both serum ferritin levels and cardiovascular diseases are effective factors to predict premature death in hemodialysis patients.
