摘要
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107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,后者为5.26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。结论改水使病区氟中毒病人生存质量改善,也促进了经济发展。
Objective Compare the costs and the utility for different defluoridation projects in Shandong province. Methods Cost-utility analysis method was used to compare the two main defluoridation projects (digging low-fluoride well,bone char defluoridation) utility. Results The difference of total costs between digging projects and BC projects had no statistical significance,but the cost per person of BC projects was higher than that of digging projects. The utility per person in people benefiting from digging projects was 10 QALYS, and that in people benefiting from BC projects was 5. 26 QALYS.There was statistically significant difference between them. Conclusions The cost--utility ratio(CUR) of digging projects was less than that of BC projects with statistical significance.
