Introduction: Hyponatremia is a common and serious problem especially for geriatric patients. This study was performed to determine the etiology, presentation, treatment, and clinical outcome of geriatric patients diagnosed with severe hyponatremia. 

Methods: 267 (158 severe hyponatremia and 109 mild hyponatremia) geriatric patients were included in the study. 

Results: In the severe hyponatremia group, the prevalence was 0.49%, where upon the most common reasons for emergency visit included neurological symptoms (53.2%), weakness (51.9%), and nausea-vomiting (47.5%). The most common reason in the etiology of severe hyponatremia was diuretic use; the most commonly used treatment regime was 3% hypertonic saline. The median time for the correction of Na levels was 96 (24 - 480) hours and 30 (6-360) hours in the severe and mild hyponatremia groups, respectively. 76.6% of the severe and 67% of the mild hyponatremia patients were followed-up in the clinic, whereas 17.1% and 22.9% were followed-up in the intensive care unit, respectively. The median hospitalization period was similar within both groups (6 days). 13% of the geriatric patients with severe hyponatremia and 21.1% of the geriatric patients with mild hyponatremia died. In our study, risk factors associated with severe hyponatremia were female gender, chronic kidney disease, angiotensin receptor blocker and thiazide use. Female gender, hospitalization period, hospitalization and sepsis were identified as risk factors associated with mortality.

Discussion: According to our literature review, this is the first comprehensive study investigating the etiology, presentation, treatment and clinical outcome in geriatric patients diagnosed with severe hyponatremia in the emergency department.
