Background: The benefits of CT scans in diagnosing and treating trauma patients are immeasurable. However, CT scans are sources of radiation and can pose serious health risks to pediatric patients when used in excess1,2. The objective of this study was to compare radiation dose for CT imaging in pediatric trauma patients at the local children's hospital (LCH) to outside hospitals that mostly treat adults.
Method: A retrospective chart review of pediatric trauma patients at LCH from January 2016 to December 2016 was conducted that included 266 patients with a total of 388 scans. 141 scans occurred in hospitals outside of LCH. These patients were subsequently transferred to LCH for further treatment. The dose length product (DLP) that measures radiation energy transfer to a plastic cylinder in the CT scanner was used to compare radiation exposure to patients at all facilities.
Results: Results are shown in Figure 1. The Mann-Whitney U test was used to find statistically significant differences in mean DLP seen in head and cervical spine CT scans with p-values of 0.032 and 0.005, respectively. Face and abdomen/pelvis CT scans were not quite statistically significant with p-values of 0.312 and 0.055, respectively.
Conclusion: Our findings warrant a potential revision of protocols in outside hospitals when treating the pediatric population. Radiation levels need to be carefully monitored and analyzed in this vulnerable cohort.
