目的：估计净效益冈比亚眼科护理计划（GECP）使用有限的定义的好处，从社会prospects.Methods：避免失明的情况下，建模使用人口预测，人口为基础的失明调查估计从1986年和1996年，并报告失明相关的死亡率差异。效益是以两次调查之间避免失明所带来的终生生产力提高来衡量的。费用包括所有的贡献，GECP之间的surveillance.Results：在1996年，1658个人比没有GECP失明。费用现值为128万美元（1995年美元）。虽然失明调查之间的净收益为负，但净终身收益为101万美元（1995年美元），内部收益率为10%。在主要敏感性分析中，假设塞内加尔公民（占患者的30%）受益相似，内部回报率为19%。结论：在撒哈拉以南非洲的一个国家，由于白内障和眼部感染导致的可避免失明，在有限的受益定义下，国家眼科保健项目的内部收益率是相当可观的。
Objective: To estimate the net benefit of the Gambian Eye Care Program (GECP) using a limited definition of benefits from a societal perspective.Methods: The number of cases of blindness avoided was modeled using population projections, population-based blindness survey estimates from 1986 and 1996, and reported blindness-related mortality differences. Benefits were measured as lifetime productivity gains that resulted from the cases of blindness avoided between the surveys. Costs included all contributions to GECP between the surveys.Results: In 1996, 1658 fewer individuals were blind than would have been without GECP. The present value of costs was US $1.28 million (1995 dollars). Although the net benefit between the blindness surveys was negative, the net lifetime benefit was US $1.01 million (1995 dollars), yielding an internal rate of return of 10%. In the primary sensitivity analysis, assuming similar benefits to Senegalese citizens, who accounted for 30% of patients, the internal rate of return was 19%. Upper bound sensitivity analyses result in internal rates of return higher than 20%.Conclusion: In one sub-Saharan African country with avoidable blindness due to cataract and eye infections, the internal rate of return of a national eye care program was substantial when using a limited definition of benefit.
