[Meta-analysis: effectiveness of the preventive interventions in agriculture accidents]

The aim of our study is to determine the effectiveness in reducing workplace accidents in agriculture using preventive interventions including awareness and effective knowledge of hazards with workers who followed training-informative programs. On the basis of the data reported in the 11 studies three categories we identified: Reduction in the number of workplace accidents: comparison between groups; Reduction in the number of workplace accidents: before-after comparison; Self-rating of injuries risk reduction. The second category showed significant statistical differences in the subgroup who followed preventive intervention compared to subgroup who did not follow this intervention. The third category showed a significant statistical increase of the Consciousness Index of the agricultural workers who followed the training-informative programs. The results suggested the need to use assessment models more suitable to the nature of the examined variables. A promising area is the evaluation of knowledge of risks achieved by workers exposed to formative-informative programs.
