Background/PurposeResearchers are constantly challenged to identify optimal mortality risk adjustment methodologies that perform accurately in pediatric trauma patients. This study evaluated the new Trauma Mortality Prediction Model (TMPM-ICD-9) in pediatric trauma patients.MethodsData were analyzed on 107,104 pediatric trauma patients included in the NTDB® in 2010 who had both a valid ISS and probability of death using TMPM-ICD-9. Discrimination was compared using the area under the receiver operator characteristic curve (AUC) and by age, blunt vs penetrating, intent, Glasgow Coma Scale (GCS), and number of injuries.ResultsThe AUC for TMPM-ICD-9 demonstrated excellent discrimination in predicting mortality versus ISS overall, 11 to 17years of age (0.96 vs 0.93), by injury type, intent, and in the lowest GCS scores. The TMPM-ICD-9 showed superior discrimination over ISS in patients with more than two injuries.ConclusionsThe TMPM demonstrated superior discrimination compared to ISS. The TMPM shows promise of a much needed and simple to use risk adjustment tool with application to both adult and pediatric patients. Researchers should continue to validate this tool in robust pediatric data sets.© 2014.
