Introduction: Trauma and injury severity score (TRISS), introduced in 1981 is a combination index based on revised trauma score (RTS), injury severity score (ISS) and patient's age. In this study we have used TRISS method to predict the outcome in trauma cases.
Materials And Methods: 1000 consecutive cases of trauma of adult age group admitted in casualty of Dayanand Medical College and Hospital Ludhiana, from 1/7/2000 onwards. Revised Trauma Score, Injury Severity Score and Age Index were recorded from which TRISS was determined. The performance of TS, ISS and TRISS as predictors of survival was evaluated using the misclassification rate, the information gain and the relative information gain.
Results: The majority of the patients were men (83.7%) and in the age group of 20-50 years. Road traffic collisions (72%) were the most common cause of trauma. The mortality rate was 4.1%. Using PER method, the TRISS method was found to have information gain of 0.049 and a relative information gain of 0.41.
Conclusions: The revised trauma score (RTS) ranged from 2.746 to 7.8408.There was a graded increase in mortality with decreasing RTS score.

Objectives: Dysnatremia is a critical electrolyte disturbance that can significantly impact the prognosis of trauma patients by influencing fluid balance, neurological function, and hemodynamics. Although sodium disorder is common in hospitalized patients, few studies have specifically examined the incidence of dysnatremia in patients presenting to the emergency department for post-earthquake trauma. The aim of this study is to evaluate the incidence of dysnatremia and the prognosis of patients with dysnatremia in trauma patients admitted to our center after the Kahramanmaraş earthquake.

Background: Pediatric trauma is a major global health concern, accounting for a substantial proportion of deaths and disease burden from age 5 onwards. Effective triage and management are essential in pediatric trauma care, and prediction models such as the Trauma Injury Severity Score (TRISS) play a crucial role in estimating survival probability and guiding quality improvement. However, TRISS does not account for age-specific factors in pediatric populations, limiting its applicability to younger patients.

Background: Most trauma occurs among young male subjects in Qatar. We examined the predictive values of the delta shock index (DSI), defined as the change in the shock index (SI) value from the scene to the initial reading in the emergency unit (, subtracting the calculated SI at admission from SI at the scene), at a Level 1 trauma center.
Aim: To explore whether high DSI is associated with severe injuries, more interventions, and worse outcomes [, blood transfusion, exploratory laparotomy, ventilator-associated pneumonia, hospital length of stay (HLOS), and in-hospital mortality] in trauma patients.

Objective: The number of patients during disastrous conditions was high, and triage is essential. In chaotic circumstances, orthopedic surgeons can also struggle with patient selection, not only for surgical selection but also for the necessity of hospitalization. So, the performance of the Injury Severity Score, New Injury Severity Score, and Trauma and Injury Severity Score was compared in victims who were struck under the wreckage and had fractures due to the Kahramanmaras Earthquake.

Background: The Trauma and Injury Severity Score (TRISS) method is a widely used tool for assessing patient severity and predicting survival probability in trauma care. However, its accuracy and applicability in the Korean context, particularly for neurotrauma patients, have not been thoroughly validated yet. Previous studies at a single institution have identified significant discrepancies between TRISS predictions and actual outcomes, particularly in severe neurotrauma cases.
