Introduction: Farm vehicle crashes (FVC) cause injury and fatality among both the users and non-users of farm vehicles. The goal of this research is identify modifiable factors of FVCs and predict injury risk due to these factors.
Methods: FVC data was collected from the departments of transportation of Iowa, Illinois, Kansas, Minnesota, Missouri, Nebraska, North Dakota, South Dakota, and Wisconsin. We conducted multivariate logistic regression analysis with generalized estimating equations to estimate the odds of injury in a FVC. The goodness-of-fit of the model was determined by using the quasi-likelihood independence criterion (QIC). Using the intercept and the odds from this model the probability of injury in a FVC under different circumstances can be calculated.
Results: Our models allow us to make inferences such as the following: If a multiple vehicle FVC occurs in ‘Iowa’ on a ‘clear’ day between ‘6-11:59am’ in ‘June through August,’ the risk of injury for a ‘male driver’ of the ‘non-farm vehicle’ who is ‘wearing a seat belt’ is 17%. However, the risk of injury would have been 43% had this individual ‘not been wearing a seatbelt.’
Conclusion: These models may help anticipate injury and supplement treatment readiness when FVCs occur.
