Scandinavian Neurotrauma Guidelines: Frequency of intracranial hemorrhage in patients over 65 years old and on anti-platelet medication.

Purpose: In 2013, the Scandinavian Neurotrauma Committee, produced an evidence-based guideline for the use of Computed Tomography (CT) in patients presenting following recent (<24 h) head injury (HI). A head CT scan is recommended for medium-risk patients with a Glasgow Coma Scale (GCS) score of 14-15, who are > 65 years old and on anti-platelet medication. The aim of this study was to determine the prevalence of intracranial hemorrhage (ICH) on head CT scans in this population, and to test for associations between ICH and baseline characteristics, symptoms and objective clinical findings.
