Abstract
We computed regression coefficients for TRISS analysis for all 4271 pediatric patients (aged 1 through 14 years) with complete data from the Major Trauma Outcome Study. We then compared predicted pediatric and adult TRISS survival probability norms. There were no statistically significant differences in the predicted and actual numbers of survivors using either norm. Differences in discrimination and reliability between the two norms were minimal. The study confirmed that the TRISS adult blunt norm is highly discriminating and reliable in predicting survival probabilities for pediatric patients. Given that both norms were equally good predictors, and the importance of a consistent system to evaluate trauma care, the authors recommend the continued use of the adult blunt trauma norm for estimating survival probability in children.
