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.
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.
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.
The revised trauma score (RTS) ranged from 2.746 to 7.8408.There was a graded increase in mortality with decreasing RTS score.
创伤和损伤严重程度评分（TRISS）于1981年提出，是一种基于修正创伤评分（RTS）、损伤严重程度评分（ISS）和患者年龄的综合指标。在本研究中，我们使用TRISS方法预测创伤病例的结局。
从2000年7月1日起，在卢迪亚纳Dayanand医学院和医院急诊室收治的1000例连续成年创伤病例。记录修正创伤评分、损伤严重程度评分和年龄指数，由此确定TRISS。使用错误分类率、信息增益和相对信息增益评估TS、ISS和TRISS作为生存预测指标的性能。
大多数患者为男性（83.7%），年龄在20至50岁之间。道路交通事故（72%）是创伤最常见的原因。死亡率为4.1%。使用PER方法，发现TRISS方法的信息增益为0.049，相对信息增益为0.41。
修正创伤评分（RTS）范围为2.746至7.8408。随着RTS评分降低，死亡率呈分级增加。
