A retrospective study using National Trauma Data Bank records from 2017 to 2023 examined head CT use in children with isolated mild traumatic brain injury across adult, pediatric, and mixed hospitals. Overall CT use remained high, ranging from 43.5% to 51.5% over the study period, with adult hospitals showing the highest rate (59.5%) compared to mixed (44.0%) and pediatric hospitals (38.8%). The authors state these findings reveal persistent gaps in guideline adoption and call for research into barriers driving this variability.
