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 bluet 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

CT Major Injury Rule

May not need a CT if all criteria are absent

  1. Abnormal CXR
  2. Distracting injury
  3. Chest wall tenderness
  4. Sternum tenderness
  5. Thoracic spine tenderness
  6. Scapula tenderness

CT All Injuries Rule

May not need a CT if all criteria are absent

  1. Abnormal CXR
  2. Distracting injury
  3. Chest wall tenderness
  4. Sternum tenderness
  5. Thoracic spine tenderness
  6. Scapula tenderness
  7. Rapid deceleration mechanism

Sensitivity

CT-Major Injury Rule

  • 99 sensitive for major injuries
  • 90% sensitive for minor injuries

CT-All Injury Rule

  • 99% sensitive for major injuries
