Aim: This study aims to investigate the 90-day and 1-year mortality and the affecting factors of mortality in patients who have started dialysis treatment for the first time. Methods: Patients who started intermittent hemodialysis for the first time in the hemodialysis unit were evaluated. Patients who received hemodialysis treatment for any reason before, patients who underwent hemodialysis due to methyl alcohol, lithium, or mushroom poisoning, and patients who started dialysis in the intensive care unit were excluded from the study. The clinical and laboratory data were obtained from the patients, at admission time, from the electronic data record system and patients' charts.Univariate and multivariate logistic regression analyses were used to identify predictive factors for 90-days and 1-year mortality-dependent variables. Results: 229 patients were included in this study. 133(58.8%) of the patients were male, 96(41.9%) were female, and the median age was 64 years. While 166 patients had pre-existing renal disease, 63 patients had no prior renal disease. The number of patients who died within 90 days, which refers to short-term mortality, was 49 (21.4%). 73 patients (31.9%) died in one year (long-term mortality). At the end of one year, 38% of the whole group of patients continued receiving renal replacement therapy, while 10% of all CKD patients had not a requirement of dialysis, and only 9.17% of the patients had renal recovery. In the multivariate analysis established for short-term mortality, the following parameters showed significant predictive features: ejection fraction (OR = 3.80, 95% CI: 1.05-13.72, p=0.042), CRP (OR = 0.20, 95% CI: 0.04-0.92, p= 0.039), age (OR = 0.21, 95% CI: 0.05-0.91, p= 0.038), and diastolic blood pressure (OR = 0.08, 95% CI: 0.02-0.28, p< 0.001). The multivariate analysis for long-term mortality indicated that systolic blood pressure (OR = 0.26, 95% CI: 0.08-0.82, p= 0.022), diastolic blood pressure (OR = 0.21, 95% CI: 0.68-0.66, p= 0.008), and potassium (OR = 0.27, 95% CI: 0.10-0.70, p= 0.007) were independent predictive markers. Conclusion: Patients with CKD who have not yet started hemodialysis treatment should be followed closely, as hypervolemia, hypotension, and hemodynamic instability increase the risk of death, according to our study. In addition, we recommend that clinical conditions such as hemodynamic instability or sepsis, which may cause hypotension in AKI-D, should be addressed as soon as possible, and optimizing the fluid-electrolyte balance carefully in those patients we determined to be at risk.
