IntroductionBlunt trauma is a leading cause of pediatric morbidity. We compared injuries, interventions and outcomes of acute pediatric blunt torso trauma based on intent.MethodsWe analyzed de-identified data from a prospective, multi-center emergency department (ED)-based observational cohort of children under age eighteen. Injuries were classified based on intent (unintentional/inflicted). We compared demographic, physical and laboratory findings, ED disposition, hospitalization, need for surgery, 30-day mortality, and cause of death between groups using Chi-squared or Fisher's test for categorical variables, and Mann-Whitney test for non-normal continuous factors comparing median values and interquartile ranges (IQR).ResultsThere were 12,044 children who sustained blunt torso trauma: Inflicted=720 (6%); Unintentional=9563 (79.4%); Indeterminate=148 (1.2%); Missing=1613 (13.4%). Patients with unintentional torso injuries significantly differed from those with inflicted injuries in median age in years (IQR) [10 (5, 15) vs. 14 (8, 16); p-value<0.001], race, presence of pelvic fractures, hospitalization and need for non-abdominal surgery. Mortality rates did not differ based on intent. Further adjustment using binary, logistic regression revealed that the risk of pelvic fractures in the inflicted group was 96% less than the unintentional group (OR: 0.04; 95%CI: 0.01-0.26; p-value=0.001).ConclusionsChildren who sustain acute blunt torso trauma due to unintentional causes have a significantly higher risk of pelvic fractures and are more likely to be hospitalized compared to those with inflicted injuries.Copyright © 2017 Elsevier Inc.
