Clinical Judgment and the Pediatric Emergency Care Applied Research Network Head Trauma Prediction Rules

We commend Babl et al1 for their well-designed subanalysis comparing clinical judgment with pediatric head trauma prediction rules to guide neuroimaging decisions, as few studies have explored such comparisons. The authors conclude that in settings with low computed tomography (CT) use such as theirs, prediction rules may have a limited influence on clinical decisionmaking in pediatric head trauma and may increase CT use. The authors note several caveats that merit further elaboration.
