A study sought to determine whether alcohol intake influences short-term mortality in patients with traumatic brain injury (TBI), using a comprehensive trauma database.
Data were collected from 7 emergency departments (EDs) between June 1, 2008 and May 31, 2010. Cases were included if the patients were older than 15 and their injuries including TBI. Demographics and outcomes were compared between patients with and without alcohol intake. The study presents the risk of mortality using hazard ratios and 95% confidence intervals. A total of 76,596 trauma patients visited the EDs during the study period; 12,980 patients were older than 15 and had TBI.
There were 4,009 (30.9%) patients in the alcoholintake group, of whom 3,306 (82.5%) patients were male, 1,450 (36.2%) patients were moved by ambulance, and 1,218 (30.4%) patients’ injuries were intentional. The most frequent injury mechanism was falling down with alcohol intake and blunt injury without alcohol intake. Mortality rate was 1.0% with alcohol intake and 2.0% without alcohol intake. After adjusting for all factors related to mortality, the hazard ratio of mortality was 0.72 in the alcoholintake group.
The authors conclude that mortality rate due to TBI in the alcohol-intake group appears to be lower compared to that in the no-alcohol-intake group after adjusting for main confounding variables.
