Minor head trauma is one of the most frequent reasons for paediatric emergency department visits worldwide. The PECARN (Paediatric Emergency Care Applied Research Network) clinical decision rule stratifies children with minor head trauma into low-, intermediate-, and high-risk categories for clinically important traumatic brain injury (ciTBI) and provides evidence-based guidance on computed tomography (CT) ordering. Despite its high diagnostic accuracy, real-world CT utilisation frequently diverges from PECARN recommendations. Non-clinical family-level factors - including socio-cultural characteristics and health literacy - may drive part of this divergence, particularly through their influence on whether families explicitly request CT imaging.
This prospective observational cohort study will enrol 200 children with minor head trauma presenting to the emergency department of SBU Bursa Yuksek Ihtisas EAH, Bursa, Turkey. The primary aim is to determine whether family socio-cultural level (composite index incorporating education, occupation, income, and housing; scored 0-10) and health literacy (Newest Vital Sign-Turkish, NVS-TR) independently predict parental demand for CT imaging. Secondary aims include determining whether parental CT demand and family socio-cultural characteristics predict CT ordering by the treating physician, describing PECARN algorithm adherence patterns in this setting, and examining parental health-seeking behaviour at 7-day telephone follow-up.
