Five-year survival rate and factors affecting the survival of hemodialysis patients

Introduction: Survival rate is important in chronic kidney disease patients due to their dependence on hemodialysis. Therefore, the aim of this study was to evaluate the survival rate of five- years and factors affecting the survival of hemodialysis patients. Materials and Methods: This historical cohort study was performed in 60 hemodialysis patients admitted to Kamyaran Sina Hospital (Iran). Statistical analysis was done using the Kaplan-Meier curve and compared by the Log-Rank test. Correspondingly, to determine the most important factors affecting the prognosis of survival of patients, we used Cox regression model. Results: The mean and median survival was 31.4 months and 34 months respectively. The survival rate of 1 year, 2 years, 3 years, 4 years and 5 years for patients were 84%, 60%, 49%, 25% and 10%, respectively. The mean albumin was significant based on the Cox regression. Conclusion: The results of Cox regression indicated that the mean of albumin was the most important factor and also had a protective effect on hemodialysis patients. Remarkably, the survival rates of these patients will be increased if the mean of albumin has an increase.
