title: Clinical efficacy of serial computed tomographic scanning in severe closed head injury patients.
abstract: BACKGROUND
  The purpose of this study was to determine whether serial computed tomographic (CT) scans of the head serve to prompt operative intervention. After the initial and 24- to 48-hour repeat scans, if no operative intervention has been performed, further serial scans are ordered on a planned basis or on the basis of changes in clinical status.
  
  
  METHODS
  This study is a retrospective review from January 1996 to December 2000. Results of the initial, follow-up, and serial CT scans were recorded for the 51 patients who met the inclusion/exclusion criteria.
  
  
  RESULTS
  One hundred seventeen (53.4%) serial CT scans were ordered. No urgent operative interventions were performed on the basis of the serial CT scans. Three scans (2.56%) led to nonurgent neurosurgical intervention.
  
  
  CONCLUSIONS
  In severe head-injured patients who are nonneurosurgical candidates on the basis of initial and repeat CT scans, serial head CT scans have little clinical efficacy and do not lead to urgent operative intervention.
