RESUMO
Cervical spine trauma is a common reason for presentation to an emergency department. However, less than 5% of patients who have suffered possible neck injury actually have an injury requiring medical treatment. Nevertheless, the consequences, both for the patient and the doctor, of a missed injury are well recognized by emergency department medical staff. This results in the vast majority of these patients receiving some form of diagnostic imaging. We describe the development of an evidence-based imaging guideline for use in the patient who has suffered cervical spine trauma. The guideline aims to help clinicians determine, at the bedside, when it is appropriate to use imaging and which imaging modality should be used first. Correct utilization of the guideline should lead to a reduction in the number of imaging tests required to reach a diagnosis without adverse patient outcomes.
