title: [Modelling length of hospital stay in motor victims].
abstract: OBJECTIVE
  To analyze which socio-demographic and other factors related to motor injuries affect the length of hospital recovery stay.
  
  
  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.
