BACKGROUND

According to the US National Highway Traffic Safety Administration, in 2010, 10,228 people were killed in alcohol-impaired driving crashes. Daily, intoxicated drivers are seen in trauma centers across the country. At our trauma center, we sought to determine the number of drivers who had a documented elevation in their blood alcohol content (BAC) and compare this with county police records to evaluate how many charges for driving while intoxicated (DWI) were issued.

METHODS

A retrospective chart review was performed for trauma admissions during a 3-year period. Patients with a BAC of less than 0.08 g/dL were excluded. Only documented drivers were included. This group of intoxicated drivers was then compared against public records from the Dallas County for any record of a charge of DWI.

RESULTS

During a 3-year period, from 2009 to 2011, 118 drivers had a confirmed BAC above the legal limit of 0.08 g/dL. Average BAC level was 0.218 g/dL. Injuries varied widely between patients with an average Injury Severity Score (ISS) of 11. Extremity fractures were seen in 27%, facial fractures were seen in 16%, and intracranial hemorrhage was seen in 7%. Forty-eight percent of the patients were admitted to the intensive care unit initially, with an average length of intensive care unit stay of 1.5 days (range, 0-25 days). Only 18% of our patients (21) received a charge of DWI. Four patients were charge with related offenses.

CONCLUSION

A motor vehicle accident may be protective against the legal ramifications of drinking and driving. Less than 20% of patients who were driving under the influence incurred any legal repercussion. Deterrents that prevent law enforcement from being able to obtain evidence needed for prosecution should be eliminated. Health care providers and law enforcement agencies should work as a team to help mitigate the incidence of drunk driving and its burden on society.
