RESUMO
OBJECTIVE: To analyze which socio-demographic and other factors related to motor injuries affect the length of hospital recovery stay. MATERIALS AND METHODS: In the study a sample of 17 932 motor accidents was used. All the crashes occurred in Spain between 2000 and 2007. Different regression models were fitted to data to identify and measure the impact of a set of explanatory regressors. RESULTS: Time of hospital stay for men is on average 41% larger than for women. When the victim has a fracture as a consequence of the accident, the mean time of hospital stay is multiplied by five. Injuries located in lower extremities, the head and abdomen are associated with greater hospitalization lengths. CONCLUSIONS: Gender, age and type of victim, as well as the location and nature of injuries, are found to be factors that have significant impact on the expected length of hospital stay.

Objetivo. Analizar los factores sociodemográficos y de las lesiones causadas por accidentes de tránsito que influyen en el tiempo de hospitalización de las víctimas. Material y métodos. Muestra transversal de 17 932 eventos de tránsito ocurridos en España entre 2000 y 2007. Se estimaron diferentes modelos de regresión para identificar y medir la influencia de los factores. Resultados. Los hombres tienen un tiempo medio de hospitalización 41% mayor al de las mujeres. La duración de la estancia hospitalaria media aumenta cinco veces cuando existen fracturas. Las lesiones en las extremidades inferiores, la cabeza y el abdomen se asocian con mayores duraciones hospitalarias. Conclusiones. El sexo de la víctima, su edad, la posición que ocupaba en el vehículo en el momento del evento, el tipo de vehículo causante y el tipo y zona de la lesión influyen significativamente en la duración de la estancia hospitalaria.
