Daily cost of an intensive care unit day: the contribution of mechanical ventilation.

Objective:To quantify the mean daily cost of intensive care, identify key factors associated with increased cost, and determine the incremental cost of mechanical ventilation during a day in the intensive care unit. Design:Retrospective cohort analysis using data from NDCHealth’s Hospital Patient Level Database. Setting:A total of 253 geographically diverse U.S. hospitals. Patients:The study included 51,009 patients ≥18 yrs of age admitted to an intensive care unit between October 1, 2002, and December 31, 2002. Interventions:None. Measurements and Main Results:Days of intensive care and mechanical ventilation were identified using billing data, and daily costs were calculated as the sum of daily charges multiplied by hospital-specific cost-to-charge ratios. Cost data are presented as mean (±sd). Incremental daily cost of mechanical ventilation was calculated using log-linear regression, adjusting for patient and hospital characteristics. Approximately 36% of identified patients were mechanically ventilated at some point during their intensive care unit stay. Mechanically ventilated patients were older (63.5 yrs vs. 61.7 yrs, p < .0001) and more likely to be male (56.1% vs. 51.8%, p < 0.0001), compared with patients who were not mechanically ventilated, and required mechanical ventilation for a mean duration of 5.6 days ± 9.6. Mean intensive care unit cost and length of stay were

Mechanical ventilation is associated with significantly higher daily costs for patients receiving treatment in the intensive care unit throughout their entire intensive care unit stay. Interventions that result in reduced intensive care unit length of stay and/or duration of mechanical ventilation could lead to substantial reductions in total inpatient cost.
