<ol>
<li> Evidence of abdominal wall trauma/seatbelt sign</li>
<li>GCS <14 with abdominal trauma</li>
<li>Abdominal tenderness</li>
<li>>1 of thoracic wall trauma, vomiting, complaint of abdominal pain, decreased breath sounds</li>
</ol>
<p>Answering no to all yields <0.1% chance of intra-abdominal trauma requiring intervention. (See MedCalc link for other calculations)</p>
<p>A prospective validation study in the Lancet yielded 100% sensitivity and negative predictive value in 7542 patients under age 18 </p>
<p>This tool can likely be used to guide imaging choices in pediatric blunt abdominal trauma patients</p>
