Prevention of farm injuries in Denmark.
OBJECTIVE
This study examined the effects of a 4-year randomized intervention program that combined a safety audit with safety behavior training in the prevention of farm injuries.


METHODS
From a random sample of farms in the county of Ringkoebing, Denmark, 393 farms with 1597 residents and employees participated in a weekly self-registration of work-related accidents and injuries during 1 year. Worktasks and time at risk were recorded. A questionnaire including items on safety behavior was also mailed to each farm. Thereafter, the farms were randomly assigned to an intervention or control group. Two hundred and one farms with 990 persons at risk participated in the intervention study. The main outcome measures were the number and severity of accidents, safety behavior, and farmsite safety audits.


RESULTS
Pre- and postmeasurements showed a substantial reduction in injury rates in the intervention group in comparison with a slight reduction in the control group. In a multivariate regression analysis the intervention effect was estimated to be a 30% injury-rate reduction of all injuries, while there was a 42% reduction for medically treated injuries only. Although none of these effects are statistically significant with the present sample size, their magnitude and direction support an intervention effect. The measures of safety behavior revealed significant improvements, and this finding supports the conclusion that the intervention effect was positive, since they concern some of the mediating factors on the pathway from intervention to improved injury rates.


CONCLUSIONS
This intervention, which focused on safety behavior and was performed as a randomized controlled trial, was followed by a substantial reduction in the number of farm injuries. The reduction was particularly marked for the more severe injuries demanding medical treatment.
