Revised indications for head CT in elderly patients with minor traumatic injuries: A retrospective analysis.

Purpose: The purpose of this study was to assess the performance of a decision-tree for head-CT indication in elderly patients presenting minor traumatic injuries MATERIALS AND METHODS: A single-centre retrospective study was performed and analyses were based on emergency CT scans of all patients aged 65 and over who experienced minor head trauma due to falls. The primary judgement criteria was the diagnosis of a traumatic intracranial haemorrhagic lesion (tICH) depicted on the CT scan. Focal neurological deficit and history of tICH on a previous CT scan were used to create the decision-tree.
