Cervical Spine Computed Tomography in Adolescent Blunt Trauma Patients: Are They Being Overutilized?

Cervical spine computed tomography (CSCT) scans are used to evaluate cervical spine traumatic injuries; however, recent evidence demonstrates that adult trauma centers (ATCs) overutilize CSCT when evaluating adolescent patients. This leads to unnecessary radiation exposure. The aim of this study is to review a level 1 ATC's use of CSCT in the adolescent blunt trauma population.

A retrospective chart review was conducted of a level 1 ATC's trauma database. Blunt trauma patients between the ages of 11 and 18 who receive a CSCT between January 2015 to December 2019 were included. The primary outcome was the prevalence of positive findings on CSCT scans. Data were analyzed using Fischer-Exact analysis and multivariate logistic regression where appropriate.

Three-hundred thirty-seven of 546 (61.7%) adolescent blunt trauma patients received CSCT. Of those, 68.2% (230) were male; the mean age was 16.6 ± 1.0 y old. Twenty-eight patients (8.3%) had a positive finding on CSCT. All patients with a positive CSCT failed the National Emergency X-Radiography Utilization study (NEXUS) criteria while 123 patients (36.5%) with a negative CSCT met NEXUS criteria.

CSCT was overutilized in our trauma center. There is a low positive CSCT scan rate among adolescent patients, which aligns with the current literature. All patients with positive CSCT passed NEXUS criteria suggesting that a quality improvement project focusing on the use of the NEXUS criteria to assess the risk of cervical spine injury could potentially reduce the use of CSCT scans by nearly 40%.
