ANALYSIS OF SURVIVAL PREDICTORS AMONG PATIENTS WITH CHRONIC KIDNEY DISEASE UNDERGOING HEMODIALYSIS TREATMENT AT A REGIONAL HEMODIALYSIS CENTER
Objective. To analyze the predictors of survival of patients with chronic kidney disease in the Lankaran Regional Hemodialysis Center of the Republic of Azerbaijan. Methods. During 2010-2019, hemodialysis care was provided to 460 patients. To assess the role of socio-demographic and clinical laboratory indicators in the formation of the probability of survival of the patient's body at the beginning of the connection of patients to dialysis, the patients were divided into subgroups according to the gradations of the noted characteristics. For all these subgroups, the survival rate and 95% of its confidence interval were calculated. Results. The overwhelming majority of patients were aged 40-60 years, the proportion of persons under the age of 40 and over 60 years was 22.6% and 30.7%, respectively. The ratio of the number of women and men among the patients was 1:1.77. The etiological cause of CKD in most patients was glomerulonephritis (41.3%), in 29.8% of patients, diabetes mellitus was the cause of renal failure. Five-year, six-year, seven-year, eight-year, nine- and ten-year survival rates (0,4208; 0,3942; 0,3862; 0,3781; 0,3700; 0,3659) indicate a slow decline in the indicator. Conclusion. The contingent of the regional dialysis center consists mainly of patients with chronic renal insufficiency caused by glomerulonephritis (41.3%) and diabetes mellitus (29.8%) mainly aged 40-60 years (46.7%). The five-year survival rate of patients treated with hemodialysis was 0.4208 (95% confidence interval 0.3679-0.4737). The predictors of survival of patients treated with hemodialysis are old age, the cause of chronic kidney disease, high systolic and diastolic blood pressure, low hemoglobin, low albumin and globulin levels, calcium and phosphates, cholesterol in the blood and body mass index.
