Accounting for the cost of scaling‐up health interventions
介绍了世界卫生组织CHOICE项目在成本效益分析中使用的非线性成本函数方法，考虑了卫生中心、交通、监督和固定成本，以更准确地估算扩大健康干预覆盖规模的真实成本。
Recent studies such as the Commission on Macroeconomics and Health have highlighted the need for expanding the coverage of services for HIV/AIDS, malaria, tuberculosis, immunisations and other diseases. In order for policy makers to plan for these changes, they need to analyse the change in costs when interventions are 'scaled-up' to cover greater percentages of the population. Previous studies suggest that applying current unit costs to an entire population can misconstrue the true costs of an intervention. This study presents the methodology used in WHO-CHOICE's generalised cost effectiveness analysis, which includes non-linear cost functions for health centres, transportation and supervision costs, as well as the presence of fixed costs of establishing a health infrastructure. Results show changing marginal costs as predicted by economic theory.
