BackgroundScheduled repeat brain CT (SRBCT) is used to monitor progression of traumatic brain injury (TBI). Previous studies have suggested that routine SRBCT can be replaced by an unscheduled repeat brain CT after deterioration on serial neurological examination. In this study, we evaluated if SRBCT has a role in the management of TBI.Study DesignRetrospective observational study of 1,019 consecutive adult patients admitted to a Level I trauma center with CT evidence of TBI on initial brain CT (IBCT). All patients with intracranial pathology on IBCT were scheduled for SRBCT and underwent sequential neurological physical examinations. Interventions (surgical or medical) after IBCT, SRBCT, or neurological change were recorded.ResultsOne thousand nineteen patients with IBCT evidence of TBI were identified from the trauma registry during a 50-month study period beginning in November 2001. Eighty-six (8.9%) of these patients went directly for craniotomy. After exclusions, 887 patients were analyzed. A total of 692 (78%) patients had a no worse first SRBCT and neurologic changes requiring intervention later developed in 11 (1.6%) of these patients. One hundred ninety-five (22%) patients had a worse first SRBCT, with 14 (7.2%) requiring immediate intervention. Seven (3.6%) worse first SRBCT patients had a subsequent SRBCT that worsened, leading to an intervention. A neurologic change that precipitated an intervention developed subsequently in an additional 19 (9.7%) patients with a worse first SRBCT. Chi-square analysis demonstrated that a first SRBCT that was worse was more likely to result in an intervention than if the first SRBCT was no worse.ConclusionsA worse SRBCT is more likely to result in neurologic intervention. SRBCT remains useful in assessing patients with TBI.Copyright 2010 American College of Surgeons. Published by Elsevier Inc. All rights reserved.
