title: Trauma faculty and trauma team activation: impact on trauma system function and patient outcome.
abstract: OBJECTIVE
  To determine the impact of the presence of an attending trauma surgeon during trauma team activation on system function and patient outcome.
  
  
  METHODS
  After a retrospective review of medical records and trauma registry, a comparative study between two American College of Surgeons Committee on Trauma Level I trauma centers was performed. One center (Hennepin County Medical Center) required a chief surgical resident, two junior residents, and a board-certified emergency medicine faculty to be present in the emergency department for all trauma team activations. The attending trauma surgeon was notified at the time of trauma team activation and was neither required to be present in the emergency department at time of patient arrival nor in the hospital 24 h/day. The other center (St. Paul Ramsey Medical Center) required a chief surgical resident, two junior residents, a board-certified emergency medicine faculty member, and an attending trauma surgeon to be present in the emergency department for all trauma activations and in hospital 24 hours/day. Over a 21-month period, all major trauma patients (Injury Severity Score > 15 or emergent operation within 4 hours of admission and any Injury Severity Score) that triggered trauma team activation were examined. Resuscitation time, time to incision, probability of survival, and mortality were analyzed.
  
  
  RESULTS
  Resuscitation time was shorter at St. Paul Ramsey Medical Center when compared with Hennepin County Medical Center. Analysis by mechanism of injury demonstrates that this was true for blunt trauma (39+/-13 vs. 27+/-12 minutes, p = 0.001) and for penetrating trauma (28+/-14 vs. 24+/-17 minutes, p = 0.01). Subgroup analysis of penetrating trauma victims demonstrated that there was a significant difference in resuscitation times for gunshot wounds but not for stabs. There was no difference in how quickly operations could be initiated for blunt trauma patients. However, in penetrating cases, time to incision was significantly shorter at St. Paul Ramsey Medical Center (50+/-29 vs. 66+/-43 minutes, p = 0.01). There was no significant difference in mortality for any category of Trauma and Injury Severity Score probability of survival in blunt or penetrating trauma. Analysis of "in-house" and "out-house" time intervals demonstrated no difference in survival in any mechanism of injury, nor was there a difference in overall mortality.
  
  
  CONCLUSIONS
  The presence of a trauma surgeon on the trauma team reduced resuscitation time and reduced time to incision for emergent operations, particularly in penetrating trauma. However, it had no measurable impact on mortality based on Trauma and Injury Severity Score probability of survival. Attending trauma surgeon presence on the trauma team improves in-hospital trauma system function without affecting patient outcome.
