Survival Analysis of Chronic Kidney Failure Patients with Comorbid Diabetes Mellitus in the Hemodialysis Room

Chronic kidney disease has been the leading cause of death at Bahteramas Regional General Hospital in Southeast Sulawesi for the past three years. This disease is often caused by non-communicable diseases such as diabetes mellitus, which is recognized by the WHO as a priority condition. Diabetes mellitus causes damage to the blood vessels in the kidneys, reducing their blood filtration function. This condition triggers the leakage of albumin protein into the urine, known as albuminuria, and can potentially lead to kidney failure. If not properly treated, kidney failure can be fatal. The survival of hemodialysis patients is influenced by the presence of diabetes mellitus as a comorbidity. The purpose of this study was to determine the survival analysis of patients with chronic kidney failure and comorbid diabetes mellitus in the Hemodialysis Room of the Bahteramas Regional General Hospital in Southeast Sulawesi Province using a historical medical record cohort design. The analysis used the Kaplan-Meier and log-rank tests as well as modeling with Cox proportional hazards regression. The results showed that patients with diabetes had a mean survival time of 458 days (CI 303–586), and the log-rank test produced a p-value of 0.016, indicating a significant effect of diabetes on patient survival. Cox proportional hazards regression showed a hazard ratio of 3.617, indicating that the risk of death in diabetic patients was 3.617 times higher than in non-diabetic patients. These findings emphasize the importance of strict diabetes management in kidney failure patients undergoing hemodialysis to improve their life expectancy.
