The clinical features, outcome and cost burden of community-acquired hypernatremia (CAH) in elderly and very elderly patients are not well known. Our aim was to investigate the etiologies, reasons for admission, clinical courses, outcomes, complications, and cost assessments of the elderly patients with CAH. ⋯ The important determinants of "CAH" in elderly subjects are accompanying Alzheimer's disease, oral intake impairment, and concomitant treatment with RAS blockers.
