Accuracy of the New Injury Severity Score in Evaluating Patients With Blunt Trauma

Inclusion Criteria: * Trauma patients admitted to the emergency department, presenting with blunt trauma, such as from motor vehicle accidents, falls, or assaults. * Patients with adequate documentation of anatomical injuries and physiological parameters required for NISS calculation. * Injury assessment and NISS calculation completed within the first 6 hours of arrival to ensure accuracy and consistency in trauma evaluation. Exclusion Criteria: * Patients under 18 years, pregnant women, or those with pre-existing medical conditions that may alter trauma scoring accuracy or management outcomes. * Patients presenting with medical emergencies, terminal illnesses, or conditions unrelated to blunt trauma to ensure focus on trauma-specific evaluations. * Patients declared dead on arrival or who do not receive active treatment in the emergency department. * Patients or their families refusing participation or withdrawing consent at any stage of the study. * Patients transferred from or to another facility or those previously treated elsewhere, as this may affect data collection and scoring reliability.
