Methods: This retrospective cohort study included all patients 15 years or younger who were admitted to the trauma centre at Aarhus University Hospital, Denmark from January 2000 to May 2014. Injury severity was calculated using the Injury Severity Score (ISS). The Wilcoxon rank-sum test was used to determine significant differences between sexes. Results: A total of 880 children (499 boys and 391 girls) were included. No significant sex-related differences were observed in the numbers admitted during the study period, age at admission or severity of injuries. Overall, 30% of the paediatric patients were admitted in the afternoon (3-6 p.m.). The crude death rate was 2.7% of all admissions. Traffic accidents accounted for 48% of all admissions and two-thirds of all deaths. All non-survivors received ISSs of 16 or higher, and 20% of deaths in this group and 42% of overall deaths occurred within the first 24 hours. Conclusions: Our study suggests that in Denmark, children admitted to a trauma centre are most likely to have been injured in traffic accidents and/or in the afternoon. Deaths were few and limited to the severely injured children; many survived despite severe injuries. Funding: none. Trial registration: not relevant. The paediatric trauma patient would be expected to differ from the adult patient because of differences in anatomy, physiology and daily activities. In addition, current knowledge about severe paediatric traumas was obtained primarily from studies conducted outside of Scandinavia. Here, cultural and infrastructural differences might be reflected by different trauma VIDENSKAB VIDENSKAB Dan Med J 2020;67(7):A10190581 Side 1 af 9
