文摘

The impact of inebriation on severity of injury is unclear. The few studies to date on this topic are limited to a particular mechanism of injury (MOI), injury pattern, or blood alcohol level (BAL). Therefore, we sought to determine the impact of BAL on injury pattern and severity across all MOI. We hypothesize that there is no relationship between BAL and injury severity when controlling for MOI.

Materials and methods

After institutional review board approval, a retrospective study was performed at an adult trauma center from January 1, 2012–December 31, 2012. All MOI were included. Injury severity was assessed using the injury severity score (ISS). Chi square and analysis of variance were used to examine the relationship between BAL, injury pattern, and ISS within each MOI. Multivariate regression analysis examined the BAL–ISS association adjusting for MOI, gender, and age.

Results

Of 1397 patients, the mean age was 44 ± 19, ISS was 7.5 ± 6.8, BAL was 93 ± 130 mg/dL, and 70% were male. Rib fracture (P = 0.002) and hemothorax and/or pneumothorax (P = 0.0009) were negatively associated with BAL, whereas concussion and soft tissue injury had a positive association with BAL (P < 0.0001). An increasing BAL had a negative correlation with ISS after fall from standing (P < 0.001), whereas bicycle collisions had a positive association (P = 0.027). Across all MOI, there was no significant association between BAL and ISS.

Conclusions

BAL is associated with ISS, in specific MOI; however, across all MOI, there was no significant association between BAL and ISS. Inebriated patients should be triaged with the same clinical index of suspicion for injury as sober patients.
