A Retrospective Observational Study of the Association of Severity of Hyponatremia with Morbidity Outcomes in Patients Admitted to Geriatric Ward in a Tertiary Care Hospital

Abstract Introduction: Hyponatremia is the most common electrolyte abnormality observed among older patients admitted to the geriatric ward. Whether the severity of hyponatremia independently contributes to morbidity and mortality is not known. Aims and Objectives: The aim is to determine the morbidity outcomes in hyponatremia and whether the severity of hyponatremia independently contributes to morbidity outcomes in patients with multimorbidity. Materials and Methods: It is a retrospective observational study conducted in geriatric medicine ward in a tertiary care hospital. Results: There was no independent correlation with the severity of hyponatremia and morbidity outcomes seen in our study. Across all severity categories of hyponatremia, nearly 75% were discharged alive. In both categories of comorbidities (i.e., less than and more than 3), more than 80% were discharged. Both in linear and logistical regression analysis, severity of hyponatremia and comorbidity status were not significantly found to affect the outcome independently. Conclusion: There was no significant association between Severity of Hyponatremia and comorbidiy status with the morbidity outcomes.
