目的 :对山东省 1980年以来改水降氟工程进行调查 ,并对这些工程的经济投入和产出进行分析比较。方法 :随机抽取 10 7处工程 ,用质量调整生命年 (QALYS)为改水的产出指标 ,分析工程的效用及效用比。结果 :发现打井工程和骨炭除氟工程总成本无差异 ,人均成本后者大于前者。而产出的QALYS前者为 10年 ,后者 5.2 6年 ,前者几乎为后者的 2倍。其成本效用比 (CUR)显示打井工程优于骨炭除氟 ,在重病区改水的CUR最小 ,即效用最大。改水使病区氟中毒病人生存质量改善 ,也促进了经济发展。
Objectives: To investigate the water reduction and fluoride reduction projects in Shandong Province since 1980, and analyze and compare the economic input and output of these projects. Methods: Randomly select 107 projects and use Quality Adjusted Life Year (QALYS) as the output indicators of water improvement to analyze the utility and utility ratio of the project. Results: It was found that there was no difference in the total cost of drilling projects and bone carbon removal projects, and the latter was greater than the former. The former QALYS produced 10 years, the latter 5.2 years, the former is almost twice the latter. The cost-effectiveness ratio (CUR) shows that the well drilling project is better than the bone carbon removal of fluoride, and the CUR of the water changes in the severe ward is the smallest, that is, the utility is the largest. Improving the quality of life of patients with fluorosis in wards also promotes economic development.
