This paper is a retrospective analysis of data on 278 persons with fatal outcomes in traffic accidents in Osjecko--baranjska County, Croatia, during a five-year period. The observed sample of casualties was divided according to the time of fatal outcome into three groups: immediately deceased (139 or 50.0%), deceased within the first 48 hours (84 or 30.2%) and deceased after 48 hours (55 or 19.8%). A comparison of data was made for the first two groups of casualties, based on the level of alcohol intoxication, and an analysis of the possible influence of alcohol intoxication on an early outcome of severe trauma, which was defined as immediate fatal outcome and fatal outcome within the first 48 hours following the trauma. Casualties from the group of immediately deceased had a significantly higher average blood alcohol level than casualties from the group of persons deceased within the first 48 hours (shown through arithmetic mean of 0.81 g/kg vs. 0.33 g/kg, p =0.000). A binary logistic regression analysis showed that every increase in blood alcohol level by 1 g/kg also increased the odds of an immediate fatal outcome by 1.92 times (p=0.004). Beside increased risks of traffic accidents, the collected data showed that alcohol intoxication of accident participants also increases their chances of an immediate fatal outcome.
