Fehlberg EA, et al. – This study explored the link between abnormal laboratory values, possibly suggesting volume depletion, and increased odds of experiencing a hospital–acquired fall in the US hospitalised patients. Findings, although, were indicative of no association between falls and laboratory indices that may indicate volume depletion, hyponatraemia seemed to confer risk for falls, this risk was higher with serum sodium levels below 126 mEq/L. Possibly, other deficits associated with hyponatraemia, like altered mental status, were associated with risk of experiencing a hospital–acquired fall.
