ObjectiveThe timely treatment of severe traumatic brain injury (TBI) is essential for limiting the effects of damage; however, there is no consensus regarding an effective method for early intervention. In August 2011, our hospital launched a novel trauma workflow using the hybrid emergency room (ER), consisting of an interventional radiology-computed tomography (CT) unit installed in the trauma resuscitation room to facilitate early interventions. The aim of this study was to evaluate effects of the hybrid ER system on functional outcomes in patients with severe TBI.MethodsWe conducted a retrospective historical control study of patients with severe TBI (Glasgow Coma Scale score ≤8) who received conventional treatment (August 2007-July 2011) or treatment in the hybrid ER (August 2011-July 2015). The primary end point was unfavorable outcome at 6 months after injury (death, vegetative state, or lower severe disability) as evaluated by the Glasgow Outcome Scale-Extended. Secondary end points included time from arrival to the start of CT examination and emergency intracranial operation. Potential confounders were adjusted with multivariable logistic regressions.ResultsAmong 158 included patients, 88 were in the conventional group and 70 were in the hybrid ER group. After model adjustment, the hybrid ER group was significantly associated with a reduction in unfavorable outcomes. Times to CT examination and intracranial operation were significantly shorter in the hybrid ER group than that in the conventional group.ConclusionsThe hybrid ER system is useful for realizing immediate CT examination and emergency surgery and improving functional outcomes in patients with severe TBI.Copyright © 2018 Elsevier Inc.
