BackgroundData suggest that prolonged Emergency Department length of stay (EDLOS) has a detrimental effect on outcomes in some critically ill patients. However, the relationship between EDLOS and outcomes in traumatic brain injury (TBI) has not been examined.ObjectiveOur objective was to determine the effect of EDLOS on neurologic outcomes in TBI patients.MethodsWe performed a retrospective analysis of a prospectively identified cohort of patients with moderate (Glasgow Coma Scale [GCS] score 9-13) and severe (GCS ≤ 8) TBI who presented to a Level 1 trauma center (2006-2010). Inclusion criteria were transfer to the intensive care unit (ICU) or operating room (OR) from the ED. Primary outcome was Glasgow Outcome Scale (GOS) score, a measure of neurologic function, at discharge. We used a proportional odds model to control for significant predictors of GOS in univariate analysis.ResultsTwo hundred and twenty-four patients were included in the analysis, 77 (34%) of which were transferred to the OR. Median EDLOS was 3.3 h and 81.2% of patients had a GOS score ≤3 (e.g., severe disability, vegetative, or deceased). In multivariable analyses, EDLOS was not associated with GOS score in either ICU bound (p = 0.57) or OR bound (p = 0.11) patients. Younger age, pupil reactivity, and absence of intubation were independent predictors of good outcomes in the ICU group. In OR patients, predictors of higher GOS score included presence of an epidural hemorrhage, absence of midline shift, and pupil reactivity.ConclusionsOur study demonstrates that EDLOS was not associated with poor outcomes in patients with moderate to severe TBI who required intensive care or early operative intervention in an academic Level 1 trauma center.Copyright © 2013 Elsevier Inc.
