Purpose: The utility of chest computed tomography (CCT) is not well established in the diagnostic algorithm of adolescent blunt trauma patients. Our study's aim was to review CCT usage in the initial evaluation of adolescent blunt trauma.
Methods: We retrospectively reviewed adolescent blunt trauma patients treated at our urban level 1 adult trauma center from 2015 to 2019. Our primary outcome was the rate of positive CCT findings. Univariate and multivariate logistic regression analyses were performed.
Results: There were 288 patients that met our inclusion criteria and 153 positive CCT and 135 negative CCT. There was no statistically significant difference between both groups in terms of age, gender, and race. Those with a positive CCT were found to have a statistically significant higher ISS than the negative CCT group (20.6 ± 12.3 vs 12.3 ± 7.6; P < .01). Those with a positive CCT were more likely to have a GCS <15 (40% vs 25%), have a positive CXR (38% vs 2%), have chest pain (16% vs 7%), and have an abnormal chest exam (27% vs 7%) than those with a negative CCT (P < .01). On multivariate analysis, positive CXR (P < .05, OR = 13.96) and ISS (P < .05, OR = 3.10) were independently associated with a positive CCT.
Conclusion: While CCT may provide valuable information, clinical exam coupled with low-ionizing radiographic imaging (i.e., CXR) may sufficiently identify chest trauma after blunt mechanisms. This shift in management can potentially reduce the risk of radiation without compromising the care of adolescent trauma patients at adult trauma centers.
