Predictive Role of Age and Albumin Levels on All-Cause Mortality in Early Hemodialysis Patients

Background: TThis study aimed to investigate the predictive role of baseline data on all-cause mortality in patients during the early stages of dialysis (3-6 months).Methods: A retrospective cohort study was conducted, collecting baseline data from dialysis patients, including age, gender, urea nitrogen, albumin, potassium, hemoglobin, iron, ferritin, transferrin saturation, parathyroid hormone, calcium, phosphorus, carbon dioxide combining power, uric acid, creatinine, glucose, cholesterol, low-density lipoprotein, and C-reactive protein.The study included 377 patients, with 105 in the deceased group.Univariate and multivariate Cox regression analyses were used to evaluate the predictive role of these factors on all-cause mortality.Results: Multivariate Cox regression analysis identified age (P < 0.001) and albumin (P = 0.010) as significant independent predictors of all-cause mortality.Each additional year of age increased the risk of mortality by 5.2%, while each 1 g/L increase in albumin decreased the risk of mortality by 7.5%. Conclusion:Age and albumin levels are important predictors of all-cause mortality in patients during the early stages of dialysis.Patients with slower recovery of albumin levels during this period may face a higher risk of mortality.These findings underscore the importance of monitoring and improving nutritional status in clinical practice to enhance the prognosis of dialysis patients.
