title: Is trauma centre care helpful for less severely injured patients?
abstract: BACKGROUND
  Trauma centres have been shown to reduce the number of preventable deaths from serious injuries. This is due largely to the rapid response of surgeons and health care teams to resuscitate, evaluate, and operate if necessary. Less is known about the effectiveness of trauma centre care on those patients who have not incurred immediate life-threatening problems and may not be as critically injured. The purpose of this study was to review the use of physician and hospital resources for this patient population to determine whether trauma team and trauma centre care is helpful or even needed.
  
  
  METHODS
  This was a retrospective study of consecutive trauma patients (n=1592) admitted from 1998 to 2002 to the trauma service of an urban level I trauma centre and recorded in the hospital trauma registry. Patients were triaged in a tiered response to more or less severely injured. All patients' care was directed by trauma surgeons.
  
  
  RESULTS
  Of the 1592 patients, 398 (25%) received a full trauma team response (Class I), 1194 were less seriously injured (Class II). The ISS for the Class I patients was 19+/-18 and for Class II patients 10+/-10. Nineteen percent of Class II patients had an ISS>15. Overall mortality in Class II patients was 2% including 20 unexpected deaths. Four hundred and three Class II patients (34%) had multisystem injuries. Of the Class II patients 423 (35%) were sent to the ICU or OR from the ED, 106 of whom required an immediate operation and 345 required an operation prior to discharge. Complications developed in 129 patients (11%), the majority of which were pulmonary.
  
  
  CONCLUSIONS
  A large proportion of those patients thought initially to be less severely injured required resources available in a trauma centre, including specialty care, intensive care, and operating room accessibility. Over one-third of these patients had multisystem injuries and almost 20% were considered major trauma, needing prioritisation of care and expertise ideally found in a trauma centre environment. Complications developed in a sizable number of patients. This patient population, because of its heterogeneity and propensity for critical illness, deserves the resources of a trauma centre.
