[Hyponatremia on admission to the emergency room as a risk factor for hospital mortality].

Background: Patients who develop hyponatremia during their hospitalization have higher hospital mortality.

Aim: To determine if the presence of hyponatremia on admission to the emergency room is a risk factor for hospital mortality.

Patients And Methods: Two hundred forty five patients consecutively admitted to the emergency room and then transferred to the Medicine Department, where they finally died, were matched for age and gender with 245 control subjects admitted to the emergency room and hospitalized in the Medicine Department at the same time, but survived.
