Mortality With and Without Whole-Body CT in Severely Injured Children

Area of Science:

• Trauma Surgery
• Pediatric Imaging
• Radiology

Background:

• The optimal imaging strategy for pediatric trauma patients remains debated.
• Whole-body computed tomography (WB-CT) is increasingly used, but its benefit in children requires evaluation.
• This study utilizes data from the German Trauma Registry (TR-DGU) to assess WB-CT's impact on outcomes in injured children.

Purpose of the Study:

• To investigate whether whole-body computed tomography (WB-CT) improves survival rates in severely injured children.
• To compare outcomes of WB-CT versus step-wise diagnostic procedures in pediatric trauma care.
• To analyze mortality predictors and perform propensity score matching for a robust comparison.

Main Methods:

• Analysis of data from the TR-DGU registry (2012-2021).
• Comparison of mortality between children and adults (≤50 years).
• Propensity score analysis of matched pairs comparing WB-CT and step-wise diagnosis in children.

Main Results:

• No significant difference in observed to expected mortality ratio between children who received WB-CT (SMR 0.97) and those who did not (SMR 0.95).
• Propensity score analysis of 1101 matched pairs showed similar mortality rates (3.9% with WB-CT vs. 4.0% without).
• WB-CT showed a survival advantage in adults, but not in children.

Conclusions:

• Whole-body computed tomography (WB-CT) does not demonstrate a survival benefit for severely injured children compared to a step-wise diagnostic approach.
• The potential risks of radiation exposure and induced malignancy in children necessitate careful consideration of WB-CT benefits versus risks.
• Clinical decisions regarding WB-CT in pediatric trauma should involve thorough team discussions weighing benefits against harms.
