Comparing NISS and ISS for Mortality Prediction in Trauma Patients

The goal of this prospective cohort study is to compare the predictive utility of the New Injury Severity Score (NISS) and the Injury Severity Score (ISS) in determining mortality outcomes among trauma patients admitted to emergency rooms (ER) in Iraq. The main questions it aims to answer are: * Does the NISS provide a more accurate prediction of mortality than the ISS? * Are there specific subgroups of trauma patients where one scoring system outperforms the other? Participants will: Be assessed using both the NISS and the ISS upon their ER admission. Have their clinical outcomes, including mortality, monitored throughout their hospital stay.
