  • Efficacy
  1. Based on prospective study with over 12,000 patients, of whom 1.3% had a significant Abdominal Injury requiring intervention
    1. Study did not incorporate FAST Exam or labs in the decision rule (due to lack of standardization across study centers)
  2. Efficacy in identifying intraabdominal injury
    1. Test Sensitivity: 97% (higher than gestalt, which was 82.8%)
    2. Test Specificity: 42.5% (lower than gestalt, which was 78.7%)
    3. Negative Predictive Value: 99.9%
