abstract="BACKGROUND: : To examine the association of scene mobility status (SMS) and injury severity and mortality among motor vehicular crash (MVC) victims. METHODS: : Adult MVC victims transported to medical facilities between 1997 and 2008 and included in the National Automotive Sampling System were studied. SMS was classified as follows: &quot;ejected,&quot; &quot;self-exited,&quot; &quot;exited with assistance,&quot; &quot;removed from the vehicle with decreased mental status,&quot; &quot;removed due to perceived serious injury,&quot; and &quot;removed for other reasons.&quot; Associations of SMS with Injury Severity Score and death were studied with contingency tables and multiple logistic regression models. RESULTS: : A total of 62,634 cases representing 13,699,294 (weighted) cases were analyzed. Two percent of the cases were ejected, 38% self-exited, 18% exited with assistance, 4% removed with decreased mental status, 14% removed due to perceived serious injury, 1% other reasons, and 25% unknown. Mortality was highest among those ejected (8.7%). Those who self-exited and exited with assistance experienced a mortality of 0.02%. Injury Severity Score >8 occurred in 51% of those ejected, 37% of those removed with decreased mental status, 21% of those removed due to perceived serious injury, 4% of those who self-exited, and 5% of those exited with assistance. Multiple logistic regression revealed that those ejected, removed due to a low mental status or suspected injury, experienced higher adjusted odds ratios of dying than those who self-exited (odds ratio of 266 [69->999], 235 [61-903], and 66 (19-227), respectively). CONCLUSION: : MVC occupants who &quot;self-exited&quot; or &quot;exited with assistance&quot; experienced a very low injury severity and mortality. Further efforts are needed to decrease the overtriaging of these patients.<p /> <p>Language: en</p>",
