To measure cost-effectiveness of an intervention to increase retrofitting of rollover protective structures (ROPS) on tractors.
Tractor overturns are the leading cause of farm fatalities. ROPS prevent these deaths. This study updates a 2011 cost-effectiveness assessment of a New York State intervention to increase use of ROPS. We subtracted intervention cost from the cost of injuries averted, then divided this figure by the number of averted injuries. We used related probabilities and costs of fatalities and injuries from published literature to calculate the program's cost-effectiveness.
The total cost of the injuries averted from 2007 to 2017 was $6 018 742 versus a total program cost of $1 776 608. The one-time retrofit costs will continue to prevent injuries as long as the tractors are used, generating additional (projected) future savings of $12 136 512, $15 781 027, and $18 924 818 if retrofitted tractors remain in operation 15, 20, or 25 years after their retrofit.
Social marketing was cost-effective for reducing injuries from tractor overturns. Public Health Implications. These results indicate that the intervention model is effective from both a public health and economic standpoint and should be expanded into other states.
衡量一项增加拖拉机防翻滚保护结构（ROPS）改装干预措施成本效益的研究。
拖拉机翻车是导致农场工人死亡的主要原因。ROPS 可预防这些死亡事件。本研究更新了 2011 年纽约州一项增加 ROPS 使用干预措施成本效益评估。我们从避免的伤害成本中减去干预成本，然后将该数字除以避免的伤害人数。我们使用相关的死亡率和伤害率概率和成本来计算该计划的成本效益。
2007 年至 2017 年，避免的伤害总成本为 601.8742 美元，而总计划成本为 177.6608 美元。一旦进行了一次性改装，只要拖拉机仍在使用，就会继续预防伤害，从而产生额外的（预计）未来节省 1213.6512 美元、1578.1027 美元和 1892.4818 美元，如果改装后的拖拉机在改装后使用 15 年、20 年或 25 年。
社会营销在减少拖拉机翻车造成的伤害方面具有成本效益。公共卫生意义。这些结果表明，从公共卫生和经济角度来看，干预模式是有效的，应在其他州推广。
