Objetivo: Identificar de las características diferenciales de positividad a alcohol en lesionados en accidentes de tráfico atendidos en un servicio de urgencias hospitalario. Métodos: Estudio transversal con sujetos de 18 años o mayores, lesionados en accidentes de tráfico, atendidos en el servicio de urgencias del Área de Traumatología del Hospital Vall d'Hebron, entre julio de 2001 y febrero de 2002. Resultados: La muestra incluyó a 431 pacientes. El 13,7% resultó positivo a la determinación de alcohol: se hallaron diferencias en los varones (odds ratio [OR] = 2,5; IC del 95%, 1,3-5,4) y los lesionados ingresados (OR = 2,7; IC del 95%, 1,3-5,4) y en los que fueron asistidos en fin de semana o festivo (OR = 3,7; IC del 95%, 2,0-6,9), de noche y madrugada (OR = 4,6; IC del 95%, 2,0-10,3) o durante la mañana (OR = 3,6; IC del 95%, 1,5-8,4). Conclusiones: Se ha determinado la existencia de subgrupos de lesionados en accidentes de tráfico con una mayor probabilidad de alcoholemia positiva, en los cuales deberían aplicarse programas de cribado y prevención secundaria más activos desde los servicios de urgencias y de traumatología.

Objective: To identify the differential features of positive blood alcohol level (BAL) in people injured in road crashes who were attended an acute care service. Methods: Cross-sectional study of persons aged 18 years old or older injured in motor vehicle crashes who were attended in the Traumatology Emergency Department of Vall d'Hebron Hospital (Spain) between July 2001 and February 2002. Results: The study sample included 431 patients. A positive alcohol test was found in 13.7% of the sample. A statistically significant and independent association was found between positive BAL and male sex (odds ratio [OR] = 2.5 [95% CI, 1.3-5.4]), hospital admission (OR = 2.7 [95% CI, 1.3-5.4]), being attended on a weekend (OR = 3.7 [95% CI, 2.0-6.9]) and being attended during the night and early morning (OR = 4.6 [95% CI, 2.0-10.3]) or in the morning (OR = 3.6 [95% CI, 1.5-8.4]). Conclusions: The present study identifies a subgroup of people injured in motor vehicle crashes with a greater likelihood of positive BAL, in whom more active screening and secondary prevention activities should be implemented within traumatology and acute care setting.
