Background

  • 8 United States level 1 trauma centers enrolled patients for derivation and validation of a decision instrument to aid in the decision to perform a chest CT in patients with blunt trauma.[1]
  • The rule has two sub-rules, one for detection of major injuries, and one for detection of all injuries (major and minor injuries) in hemodynamically stable, non-intubated patients
