A community educational campaign implemented in two Kentucky counties was effective in influencing farmers to retrofit their tractors with rollover protective structures (ROPS) to protect tractor operators from injury in the event of an overturn. This article reports on the cost-effectiveness of this program in the two counties when compared to no program in a control county. A decision analysis indicated that it would be effective at averting 0.27 fatal and 1.53 nonfatal injuries over a 20-year period, and when this analysis was extended statewide, 7.0 fatal and 40 nonfatal injuries would be averted in Kentucky. Over the 20-year period, the cost-per-injury averted was calculated to be $172,657 at a 4% annual discount rate. This cost compared favorably with a national cost of $489,373 per injury averted despite the additional program cost in Kentucky. The principle reason for the increased cost-effectiveness of the Kentucky program was the three-fold higher propensity for tractors to overturn in Kentucky. The cost-per-injury averted in one of the two counties was $112,535. This lower cost was attributed principally to incentive awards financed locally for farmers to retrofit their tractors with ROPS.
在肯塔基州两个县开展的一项社区教育活动有效地促使农民为其拖拉机加装翻车保护结构（ROPS），以保护拖拉机操作员在翻车时免受伤害。本文报告了与对照县未开展该项目相比，该项目在这两个县的成本效益。一项决策分析表明，在20年期间，该项目将有效避免0.27起致命伤害和1.53起非致命伤害；若将该分析扩展至全州范围，肯塔基州将避免7.0起致命伤害和40起非致命伤害。在20年期间，按4%的年贴现率计算，避免每起伤害的成本为172,657美元。尽管肯塔基州有额外的项目成本，但该成本与全国每避免一起伤害489,373美元的成本相比仍具有优势。肯塔基州项目成本效益提高的主要原因是该州拖拉机翻车的可能性高出三倍。两个县中的一个县避免每起伤害的成本为112,535美元。这一较低成本主要归因于当地为农民为其拖拉机加装ROPS提供的激励奖励。
