The revised trauma score (RTS) was developed more than 20 years ago. Few studies investigated its usefulness in predicting trauma outcomes. This is especially true for the weighted version of RTS (RTS‐w). The aim of this study was to test the predicting power of RTS‐w for the trauma outcomes including mortality, admission to intensive care unit (ICU), hospital length of stay and ICU length of stay through a comparison with Injury Severity Score (ISS). Methods Descriptive data, variables related to the trauma scores and outcomes were collected. The statistical performance of RTS‐w and ISS in predicting the trauma outcomes using receiver operating characteristics (ROC) curves and the area under the curve (AUC) with 95% confidence interval and p value were calculated. The Hosmer‐Lemeshow chi‐squared statistic was performed to measure its calibration. Results A total of 3323 patients were enrolled in the study. RTS‐w was significantly better than ISS in predicting mortality of trauma patients (AUC: 0.934 vs.0.880, p<0.0001). However, for the other three outcomes, i.e. admission to ICU, hospital length of stay and intensive care unit length of stay, the performance of RTS‐w was inferior to ISS. Conclusions The RTS‐w is a better predictor of mortality than ISS. But its ability to predict other trauma outcomes is not as good as ISS. More studies are needed to identify the predictive ability of RTS‐w for the outcomes other than mortality. Besides, updating the coefficients of the formula may make RTS‐w more accurate.
