Evaluation of Cranial Computed Tomography use and Guideline Compliance in Head Trauma Patients Presenting to the Emergency Department.

Background: Head trauma was the significant public health issue and a common cause of emergency department visits. Cranial computed tomography (CT) was widely used in its evaluation; however, overuse-particularly in mild cases-raises concerns about patient safety and healthcare efficiency.

Aim: This study aimed to evaluate the appropriateness of cranial CT use in head trauma patients, its relationship with Glasgow Coma Scale (GCS) scores, and the prevalence of potentially avoidable imaging.

Methods: This retrospective study included 1,000 patients presenting with head trauma, who underwent cranial CT. Data collected included demographics, trauma mechanism, GCS score, CT findings, and indication for imaging. CT necessity was assessed using the Canadian CT Head Rule and New Orleans Criteria. CTs performed in patients with GCS 13-15, normal findings, and no guideline-based indications were classified as potentially avoidable.

Results: Of all patients, 65% were male, with a mean age of 42.1 ± 20.7 years. Mild trauma (GCS 13-15) was present in 77.5% of cases. Intracranial pathology was detected in 35.9% overall, with higher rates in patients with moderate and severe trauma. Unnecessary CT imaging was found in 57% of all cases, and in 80.2% of mild trauma cases. A statistically significant association was found between lower GCS scores and intracranial findings (P < 0.001).

Conclusion: Cranial CT was often overused in mild head trauma without adherence to clinical guidelines. Promoting the use of decision support tools and raising awareness among clinicians and patients are crucial for reducing potentially avoidable imaging, radiation exposure, and healthcare burden.
