Close to zero preventable in-hospital deaths in pediatric trauma patients - An observational study from a major Scandinavian trauma center.

BACKGROUND

In line with international trends, initial treatment of trauma patients has changed substantially over the last two decades. Although trauma is the leading cause of death and disability in children globally, in-hospital pediatric trauma related mortality is expected to be low in a mature trauma system. To evaluate the performance of a major Scandinavian trauma center we assessed treatment strategies and outcomes in all pediatric trauma patients over a 16-year period.

METHODS

A retrospective cohort study of all trauma patients under the age of 18 years admitted to a single institution from 1st of January 2003 to 31st of December 2018. Outcomes for two time periods were compared, 2003-2009 (Period 1; P1) and 2010-2018 (Period 2; P2). Deaths were further analyzed for preventability by the institutional trauma Mortality and Morbidity panel.

RESULTS

The study cohort consisted of 3939 patients. A total of 57 patients died resulting in a crude mortality of 1.4%, nearly one quarter of the study cohort (22.6%) was severely injured (Injury Severity Score > 15) and mortality in this group decreased from 9.7% in P1 to 4.1% in P2 (p<0.001). The main cause of death was brain injury in both periods, and 55 of 57 deaths were deemed non-preventable. The rate of emergency surgical procedures performed in the emergency department (ED) decreased during the study period. None of the 11 ED thoracotomies in non-survivors were performed after 2013.

CONCLUSION

A dedicated multidisciplinary trauma service with ongoing quality improvement efforts secured a low in-hospital mortality among severely injured children and a decrease in futile care. Deaths were shown to be almost exclusively non-preventable, pointing to the necessity of prioritizing prevention strategies to further decrease pediatric trauma related mortality.
