abstract="OBJECTIVE: To clarify the usefulness of grade classification for injury severity scores applied in Shonan-area Medical Control Council. <br><br>METHODS: The participants included 11,668 injury cases that occurred in this jurisdiction from April to September 2016. Multivariate analysis was performed using &quot;severity at the time of the disease&quot; a s the response variable. The AUC-ROC was also compared with and without Grade classification, and potential improvements in discrimination ability were examined. <br><br>RESULTS: There were 11,271 subjects in the &quot;mild/moderate&quot; group and 397 subjects in the &quot;severe/dead&quot; group. Almost all explanatory variables were significant and independent risk factors in the multivariate analysis, and the &quot;Load & Go adaptation&quot; had a particularly high odds ratio of 20.2. Discrimination ability improved (AUC-ROC: 0.773 VS. 0.787) when Grade classification was added to the conventional pre-hospitalization evaluation items. <br><br>CONCLUSION: Load & Go adaptation has a great influence on severity, and discrimination ability is improved through Grade classification.<p /> <p>Language: en</p>",
