<p>Background: Traumatic brain injury (TBI) patients need repeat head computed tomography (CT) in many cases. But the necessity and factor of repeat head CT is unclear. The purpose of the present study is to assess the necessity and factor of repeat head CT in TBI patients.</p><p>Methods: A retrospective study performed in an emergency medical center between April 2010 and November 2011. The TBI patients who dead the first 24 hours, directly operat­ed and did not follow repeat head CT were excluded. Clinical data collected included age, sex, time between onset and first head CT, type of head trauma, injury severity score (ISS) on admission, Glasgow coma scale, and function of coagulation.</p><p>Result: 104 patients were assessed within 20 months. The necessary factors of repeat head CT were hematoma volume in first CT, ISS on admission and soluble fibrin. Positive predictive rate was 75% and negative predictive rate was 83% in the prediction formula with these parameters.</p><p>Conclusion: It is possible to predict the progression of TBI in part with these parameters.</p>
