This paper draws attention to the importance of incorporating weights for time preference and productivity in using the concept of healthy days of life lost to evaluate healthy projects. Two alternative health strategies are defined for Ghana and evaluated, over a range of discount rates from 0 to 20%, with regard to the present value of productive life saved. It is found that the relative ranking of the projects is sensitive to the choice of discount rates. The sensitivity of disease rankings to the underlying morbidity and fatality rates is also examined and the results underline the importance of obtaining better epidemiological baseline data and information on project effectiveness if the potential usefulness of the healthy days of life approach to project evaluation is to be fully realized.
本文提请注意在运用生命损失健康天数的概念评估健康项目时纳入时间偏好和生产力权重的重要性。针对加纳定义并评估了两种替代性健康策略，在0%至20%的一系列贴现率范围内，考量了所挽救生产性生命的现值。研究发现，这些项目的相对排名对贴现率的选择敏感。还考察了疾病排名对潜在发病率和死亡率的敏感性，结果强调，如果要充分实现生命损失健康天数方法对项目评估的潜在效用，获取更好的流行病学基线数据和项目有效性信息至关重要。
