Does mild-to-moderate hyponatremia correlate with worse outcomes in comprehensive geriatric assessments in elderly inhospital patients?
Mild-to-moderate hyponatremia is associated with significantly worse functional, cognitive, and nutritional status in hospitalized geriatric patients, highlighting the need to consider serum sodium levels when interpreting geriatric assessments.
Gosch et al. (2012) conducted a case-control in Geriatric inhospital patients (n=2,880). Mild-to-moderate hyponatremia (118-131 mmol/l) vs. Normonatremia (>135 mmol/l) was evaluated on Results in structured tests for functional and cognitive impairments, depression and malnutrition. Mild-to-moderate hyponatremia (n=129) in geriatric patients was associated with significantly worse performance on all standardized geriatric assessment tests compared to normonatremic controls (n=129).
