title: The importance of vehicle rollover as a field triage criterion.
abstract: BACKGROUND
  The objective of this article was to review the importance of vehicle rollover as a field triage criterion. In 1987, field triage criteria were developed by the American College of Surgeons Committee on Trauma that have been propagated repeatedly over the subsequent 20+ years. The field triage decision scheme is based on abnormal physiology, obvious abnormal anatomy, mechanism of injury likely to result in severe injury, and other factors (age, etc.) and was supported by available science at that time. In 2005, the triage scheme was revised by a committee, and vehicle rollover as a crash scene triage criterion was dropped in 2006.
  
  
  METHODS
  The medical literature and data from the Department of Transportation/National Highway Traffic Safety Administration (NHTSA) Fatal Accident Reporting System and the National Automotive Sampling System were analyzed to determine the contribution of rollover to morbidity and mortality.
  
  
  RESULTS
  Vehicle rollovers represent a small but significant percentage of crashes; of the almost 12 million vehicle crashes reported by NHTSA in 2004, only 2.4% were rollovers, but these accounted for one-third of all crash-related occupant deaths and about 25,000 serious injuries every year. Rollovers are associated with the second highest number of vehicle occupant deaths by crash mode, three times the risk of injury when compared with other impact directions (p < 0.0001), specific types of injury such as head and spinal cord injuries, and a risk of death >15 times the risk in nonrollover crashes.
  
  
  CONCLUSIONS
  The data and literature unequivocally show a strong and disproportionate association between vehicle rollover and injury severity and death. Because it is difficult to devise simple, accurate decision rules for point of wounding and vehicle crash scene triage, simple, powerful relationships should be used when possible. Thus, the exclusion of rollover as a triage criterion seems to be ill advised.
