FACTORS AFFECTING HOSPITAL MORTALITY IN PATIENTS WITH CHRONIC KIDNEY DISEASE HOSPITALIZED FOR HYPERKALEMIA

Abstract

OBJECTIVE: Hyperkalemia is an electrolyte imbalance that can lead to fatal results if not corrected. Patients with chronic kidney disease are prone to be hyperkalemic. Knowing the factors associated with hospital mortality in patients hospitalized for hyperkalemia may reduce mortality caused by hyperkalemia. In the present study, we aimed to research the factors associated with hospital mortality in patients with chronic kidney disease hospitalized for hyperkalemia. MATERIAL AND METHODS: Patients who were hospitalized in the nephrology clinic between January 2019 and April 2022 and whose serum potassium level was >5.1 mEq/L were included in the study. Patients were divided into two groups as in-hospital deaths and survivors. The groups were compared in terms of laboratory, clinical, and demographic characteristics. RESULTS: The current study includes 123 cases with a diagnosis of chronic kidney disease. The mean age of the participants was 65.92±13.7 years. Age, diabetes mellitus, coronary artery disease, hemodialysis, potassium level, calcium and pH were found to be independent risk factors for mortality (p= 0.004, p< 0.001, p= 0.004, p=0.009, p=0.001, p=0.007,and p=0.008 respectively). CONCLUSIONS: Poor outcomes can be reduced by knowing the factors affecting mortality in patients hospitalized for hyperkalemia. In hyperkalemic patients with increased in-hospital mortality risk, the mortality risk can be minimized with additional precautions and rapid intervention.
