Evaluation of different trauma score systems / 中华创伤杂志

ABSTRACT

Objective　To investigate the effective application of trauma score methods and decrease the errors of evaluation.　Methods　The injury severity of 1 855 patients, including 583 outpatients, 907 inpatients, and 365 ICU patients, evaluated with various common-used trauma score methods was analyzed comparatively. 　Results　The area under the receiver operating characteristics curves (AUC) of different trauma scoring methods were 0.81-0.91. Specificity, sensitivity, and accuracy were above 78%. Excessiveness of scale in severity and undertriage were found for physiological indexes; whereas insufficiency of scale in severity and overtriage for anatomic indexes. The errors may happen if the prognosis of trauma patients merely rely on physiological, anatomy or age parameters. 　Conclusions　The use of different trauma score methods should be in combination with individual conditions and specific injury.
