Objectives: To analyze the impact of the Drunk-Driving Law
on the characteristics and severity of traffic accident victims
and to identify risk factors for mortality before and after law
Materials and methods: A retrospective, quantitative study
that analyzed victims of traffic accidents attended at a hospital
in São Paulo, Brazil, between 2006 and 2010, through the
analysis of medical records. The Drunk-Driving Law was
considered the time frame of this research, and the victims were
distributed in two groups: Before the law (January 2006 to June
2008) and after the law (July 2008 to December 2010). Pearson
chi-square, Mann–Whitney, and multiple logistic regression
tests were used, with a significance level of 5%.
Results: The sample consisted of 1,405 victims, the majority
being males (78.01%), with a mean age of 37.39 years. In the
group comparison (before and after the Drunk-Driving Law),
there was a significant difference related to the external cause,
admission to the ICU, and discharge conditions. Factors
associated with prelaw mortality were age, number of injured
body regions, and New Injury Severity Score. The length of
hospital stay and the Revised Trauma Score were considered
as protective factors for this outcome. After the validity of the
law, in addition to the variables described earlier, the head/
neck and abdomen regions most severely injured were added
as risk factors for mortality.
Conclusion: The impact of the Drunk-Driving Law set a positive
outcome in the survival of the victims. However, when it comes
to the statistics and severity of the trauma, it is necessary to
sustain the law with reinforcement of the inspection so that
more lives are saved.
Clinical significance: The results of this study provide support
to managers on the importance of sustaining the law and the
need of implementing new trauma prevention strategies.
