PECARN Cervical Spine Injury Prediction Rule: 0 — No risk finding. Interpretation: No risk finding What to do: The published algorithm supports clinical clearance without neck imaging. Inputs: GCS 3 to 8 or AVPU unresponsive: false; Abnormal airway, breathing, or circulation: false; Focal neurologic deficit: false; Altered mental status short of the high-risk consciousness finding: false; Neck pain: false; Posterior midline neck tenderness: false; Substantial head injury: false; Substantial torso injury: false Source: Leonard JC et al. PECARN prediction rule for cervical spine imaging of children presenting to the emergency department with blunt trauma: a multicentre prospective observational study. Lancet Child Adolesc Health. DOI: 10.1016/S2352-4642(24)00104-4. PMID: 38843852. High-risk findings are GCS 3–8 or AVPU unresponsive, abnormal airway breathing or circulation, and a focal neurologic deficit. CART findings are neck pain, altered mental status (GCS 9–14, AVPU verbal or pain, or other altered mental status), posterior midline neck tenderness, substantial head injury, and substantial torso injury. The published algorithm sends any high-risk finding to CT, any CART finding without a high-risk finding to plain radiography, and no findings to clinical clearance. (2024)
