Incremental impact of hyponatremia on components of hospital resource utilization and costs among patients with pneumonia*

Incremental increase

95% CI

ICU LOS (days)


-0.25, 2.04

HLOS (days)


0.01, 0.69

Hospital costs


$98, $2,682

MV = mechanical ventilation; ICU = intensive care unit; LOS = length of stay; HLOS = hospital length of stay *Derived from multivariable linear regression models adjusting for age, gender, race, region, teaching hospital, admission source, principal payer, and Deyo-CCI score, ICU and MV in first 48 hrs, and mortality
