目的：为克服ＴＲＩＳＳ法用于国人时所受国外权重的影响，探讨修正严重创伤结局研究（ＭＴＯＳ）权重的可行性．方法：以国人１２９７例创伤评分资料经多元回归计算出权重ｂ０～ｂ３的新值，与ＭＴＯＳ权对比．结果：常数项ｂ０负值减少，解剖权ｂ２负值增加，生理权ｂ１和年龄权ｂ３的变化因创伤类型而异．代入ＴＲＩＳＳ法算出国人伤员生存概率差异显著．新权预测的准确性和特异性有提高，但敏感性下降．结论：建立国人大型创伤数据库，具有修订院内创伤评分权重系数的必要性和可行性．
Aim: To overcome the inference from foreign coefficients to the Chinese trauma scoring of the trauma and injury severity score (TRISS), a revision of TRISS weighted coefficients is investigated. Methods: A trauma database was applied for trauma scoring with RTS ISS TRISS system to 1297 Chinese victims. A multivariation logical regression was analysed between outcome and severities of trauma score, to get a serial of new weighted coefficiences of Chinese TRISS usage. Results: The RTS, ISS,Age score and probability of survivor (Ps) of dead group were higher than those of survival group. New values of RTS ISS Age coefficients differed from MTOS ones, in ways of the constant decreased its negative value, and the ISS weight b 2 increased its negative value, but RTS weight b 1 and age weight b 3 changed from trauma types. MTOS's values and new values of weighted coefficients were used to 1297 patients for prognosis by calculating Ps. Accuracy of new values (90.13%) was a little higher than that of MTOS's (89.5%), with a promotion in specialization but a loss in sensitivity. Conclusion: A revision of TRISS's weighted coefficients is either necessary or feasible. To achieve this purpose, a Chinese trauma database with large capacity is recommended.
