Globally, 12.8 million children have vision impairment due to uncorrected refractive error (URE). In Mongolia, one in five children needs but do not have access to spectacles. This pilot cost-benefit analysis aims to estimate the net benefits of a children's spectacles reimbursement scheme in Mongolia.
A willingness-to-pay (WTP) survey using the contingent valuation method was administered to rural and urban Mongolia respondents. The survey assessed WTP in additional annual taxes for any child with refractive error to be provided government-subsidised spectacles. Net benefits were then calculated based on mean WTP (i.e. benefit) and cost of spectacles.
The survey recruited 50 respondents (mean age 40.2 ± 9.86 years; 78.0% women; 100% response rate) from rural and urban Mongolia. Mean WTP was US$24.00 ± 5.15 (95% CI US$22.55 to 25.35). The average cost of a pair of spectacles in Mongolia is US$15.00. Subtracting the average cost of spectacles from mean WTP yielded a mean positive net benefit of US$9.00.
A spectacle reimbursement scheme is potentially a cost-effective intervention to address childhood vision impairment due to URE in Mongolia. These preliminary findings support the proposal of the inclusion of children's spectacles into existing Social Health Insurance. A much larger random sample could be employed in future research to increase the precision and generalisability of findings.
在全球范围内,有 1280 万儿童因未矫正的屈光不正而导致视力受损。在蒙古,五分之一的儿童有配镜需求,但无法获得眼镜。本试点成本效益分析旨在估算蒙古儿童眼镜报销计划的净效益。
采用条件价值评估法对蒙古农村和城市的受访者进行意愿支付(WTP)调查。该调查评估了为有屈光不正的任何儿童提供政府补贴眼镜而额外缴纳年度税款的意愿支付。根据平均 WTP(即效益)和眼镜成本,计算净效益。
该调查从蒙古农村和城市共招募了 50 名受访者(平均年龄 40.2±9.86 岁;78.0%为女性;应答率 100%)。平均 WTP 为 24.00 美元±5.15(95%置信区间 22.55 美元至 25.35 美元)。蒙古一副眼镜的平均成本为 15.00 美元。从平均 WTP 中减去眼镜的平均成本,得出了 9.00 美元的平均正净效益。
眼镜报销计划可能是解决蒙古儿童因屈光不正导致视力受损的一种具有成本效益的干预措施。这些初步结果支持将儿童眼镜纳入现有的社会健康保险的提议。未来的研究可以采用更大的随机样本,以提高研究结果的准确性和普遍性。
