Introduction:
Chronic kidney disease (CKD) is a major public health problem due to the high mortality associated with it. Hemodialysis is the only available renal replacement therapy in Chad, and it is 100% subsidized by the State. This technique is often associated with various complications. Since the creation of the hemodialysis unit at CHUR (Renaissance Teaching Hospital Center), no data has been established regarding mortality and its predictive factors.
Methods:
This was a descriptive and analytical cross-sectional monocentric study conducted in the hemodialysis unit of CHU-R/Chad. The study period spanned 5 years, from January 2018 to December 2023. Patients not followed in the department and those on dialysis for acute kidney failure were not included in the study. The studied variables included sociodemographics, comorbidities, the initial nephropathy, types of vascular access for dialysis, causes of death, as well as the biochemical and hematological profiles of the patients.
Results:
During our study period, we recorded 157 patients treated with chronic hemodialysis, of which 37 patients died, representing a mortality rate of 23.5%, with a male predominance. The average age was 54.7 years. Patients had comorbidities such as hypertension in 59.5%, diabetes in 10.8%, and both combined in 21.6%. The main etiologies of CKD were dominated by hypertension (46%), undetermined causes (29.7%), diabetes (18.9%), and polycystic kidney disease (5.4%). Among the dialysis methods used, 54% had a central venous catheter (CVC), and 46% had an arteriovenous fistula (AVF). The causes of death were predominantly cardiovascular diseases in 19% of cases.
Conclusions:
The number of deaths among hemodialysis patients is high in our hospital. Cardiovascular causes play a significant role in the mortality of these patients
