Accurate identification of children at risk for clinically important traumatic brain injury (ciTBI) is essential to reduce unnecessary computed tomography (CT) imaging. This study evaluated the diagnostic performance of the PECARN (Pediatric Emergency Care Applied Research Network) clinical decision rule in children with minor head trauma presenting to a tertiary care hospital in South India.Methods: In this observational study conducted between September 2022 and April 2024, 235 children aged &lt;18 years presenting with head trauma and Glasgow Coma Scale scores of 14\u201315 were prospectively enrolled. Participants were stratified into age-specific PECARN risk categories. Diagnostic performance was assessed against ciTBI outcomes defined by clinical and radiological criteria.Results: The PECARN rule demonstrated strong diagnostic performance, with a sensitivity of 82.4%, specificity of 74.1%, and an area under the receiver operating characteristic curve of 0.90 (P=0.01). No cases requiring neurosurgical intervention were missed. Children aged \u22652 years had a higher incidence of ciTBI than those aged &lt;2 years (13.4% vs. 1.8%, P=0.048). ciTBI was significantly associated with loss of consciousness, vomiting, severe headache, and signs of basilar skull fracture (all P&lt;0.001).Conclusions: The PECARN rule appears to be a reliable and safe tool for evaluating pediatric minor head trauma in Indian emergency settings. Its high sensitivity and negative predictive value support its use in reducing unnecessary CT imaging while accurately identifying children at risk for ciTBI.<\/jats:p>","DOI":"10.20408\/jti.2025.0165","type":"journal-article","created":{"date-parts":[[2026,4,22]],"date-time":"2026-04-22T07:54:21Z","timestamp":1776844461000},"page":"144-150","update-policy":"https:\/\/doi.org\/10.20408\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation
