Prediction Model for Survival of Trauma Patients

One of the most common calculators used for predicting survival of trauma patients is TRISS (Trauma Injury Severity Score) which is based on multiple regression analysis from the Major Trauma Outcome Study (MTOS) database. Based on the data set of 1,009 trauma patients of a tertiary care hospital in Pakistan, data mining was carried out using Logistic Regression Modelling using an all subsets approach. Models were formulated and ranked based on accuracy, Area under Receiver Operating Curve (AUC) and an overall performance measure that include AUC, sensitivity and specificity. Various models were found to perform better than TRISS. Furthermore, reduced models were also formulated that include factors that are simple to determine and models were found to outperform TRISS.
