This study documents the strong association of alcohol in trauma-related deaths. In a previous study alcohol was present in 62.8% of homicide victims, 48.6% of unintentional injury fatality victims, 35.3% of persons who committed suicide, and 14.4% of persons who died of natural causes. The present study uses the legal limit of 100 mg/100 mL to include patients as having an alcohol-associated trauma death. In addition the study includes patients who die up to 20 hours after injury. These features of our study result in the lower reported frequency rates. Our study confirms that alcohol is strongly associated with trauma deaths resulting from motor vehicle crashes. It also demonstrates a strong association between alcohol use and victims of all types of trauma mortality; specifically those victims of gunshot wounds, burns, stabbings, and falls all are frequently using alcohol. This information is of importance for those who treat such injured patients, since such tests as neurologic examination frequently will be compromised by the use of alcohol in the victims of major trauma. Perhaps most importantly this information can be of help in designing appropriate strategies in attacking this problem the best possible way--by prevention.
