Purpose: Purposeful management of paediatric trauma is important to ensure injuries are identified and treated appropriately. Computed Tomography (CT) is a well-defined tool for diagnosing traumatic injury. Selective use of CT in paediatric patients is important to limit exposure to ionising radiation. Our study aims to analyse the patterns of usage of CT imaging for trauma in our paediatric emergency department. Methodology: A retrospective analysis of all CT Trauma imaging performed on paediatric patients (Age 0-15) who attended Christchurch Hospital Emergency Department (ED) between 2017 and November 2022. Results: A total of 746 paediatric patients underwent CT imaging for assessment of trauma. 250 Patients who had imaging for isolated limb injuries or facial fractures were excluded. 65 patients were classified as major trauma ( ISS ≥ 12). Eighty-one patients (16%) had a Trauma Panscan (defined as CT head and/or neck, chest and abdomen/pelvis). The remaining patients had selective imaging based on clinical concern for injury. Thirty-six panscans (44%) were performed on patients with Major trauma and 45 panscans (56%) were performed on patients with minor trauma. Only 45 (10%) of patients with minor trauma had a panscan. Conclusions: These results Indicate that the majority of paediatric patients attending Christchurch Hospital ED receive selective CT imaging for their injuries. Patients with major trauma were more likely to have complete panscans compared to minor trauma. Further analysis will aim to estimate the burden of ionising radiation on trauma patients and ensure our trauma imaging practices are in line with international guidelines.
