Abstract
Hyponatremia is a common finding in hospitalized patients. In this retrospective cohort study we assessed the characteristics and outcome of acute medical admissions with hyponatremia. Compared to the normal sodium group, those with hyponatremia were significantly older and the Charlson Comorbidity Index (CCI) was higher. The number of admissions to MCU/ICU between both groups was similar, but hyponatremic patients had a longer length of stay and both 28-day and one-year mortality were higher, even in patients with mild hyponatremia. Hyponatremia was independently associated with mortality after adjustment for age, CCI and polypharmacy, as was found in the subgroup with mild hyponatremia.

Abstract
The aims of this retrospective cohort study were to retrieve characteristics and outcomes of older (65+) medical patients who are directly admitted to ICU from the ED and to compare these with those admitted to ICU from a ward.
Of 1396 patients, 21 (1.5%) were directly admitted to ICU and 54 (3.9%) after a delay. Blood pressure was lower and respiratory rate higher in the direct than in the delayed group. The direct group had lower mortality (28-day: 19.0 vs.
38.9%, p=0.14; 1-year: 42.9 vs. 66.7%; p=0.06), shorter length-of-stay and returned more frequently to independent living than the delayed group.
Only a fraction of older patients are admitted to ICU; directly admitted patients tend to have better outcomes.
