Streck CJ et al. Identifying children at very low risk for blunt intra-abdominal injury in whom CT of the abdomen can be avoided safely. J Am Coll Surg. DOI: 10.1016/j.jamcollsurg.2016.12.041. PMID: 28130170. The derived rule, in descending order, is aspartate aminotransferase above 200 U/L, an abnormal abdominal examination, an abnormal chest radiograph, a report of abdominal pain, and abnormal pancreatic enzymes. Negative predictive value was 99.4% for any intra-abdominal injury and 100.0% for injury needing acute intervention when none of the five variables were present. The very-low-risk group was 34% of 2,188 children. (2017)

Scope: Children younger than 16 years after blunt abdominal trauma, evaluated within 6 hours, who did not have an abdominal CT before transfer. The paper names the examination, chest radiograph, pain report, and pancreatic enzymes as abnormal or present, without a second numeric cutoff.
