目的介绍失能调整寿命年(DALY)与人力资本法结合估计间接经济负担的方法。方法按照全球疾病负担研究(GBD)中计算DALY的方法,以年龄组分别计算出DALY,再利用DALY与人力资本法结合的方法中推荐的生产力权重加权求和。结果首先在计算DALY中,固定取值均参照GBD,惟一的主观指标是失能评估,在GBD中,要求8～12名各个国家和地区的不同专业的专家组成团,采用人数交换法和时间交换法评估失能,显然这样的方法在大多数研究中均无法实现。采用稍加修改的日常生活行为能力(ADL)量表,按照GBD中失能的理解重新赋值后计算出失能权重;其次,依据国民生产总值(GNP)及不同年龄组在社会价值的创造中赋予的不同生产力权重,分别计算出不同年龄组的间接经济负担,最后相加求得总人口的间接经济负担。结论DALY与人力资本法结合的方法估算间接经济负担是目前较为合理的方法,但其中DALY的计算较困难。
Objective To introduce the method of combining disability adjusted life years (DALY) and human capital method to estimate the indirect economic burden. Methods According to the method of DALY calculation in the Global Disease Burden Study (GBD), DALY was calculated in the age group, and the weighted sum of productivity weights recommended by the method combining DALY and the human capital method was used. Results First of all, in the calculation of DALY, the fixed values refer to GBD. The only subjective index is the disability evaluation. In GBD, 8 to 12 experts from different countries and regions are required to form a group, using the number exchange method and time. The exchange method assesses disability. Obviously, this method cannot be achieved in most studies. Use a slightly modified ADL scale to calculate the disability weights after reassignment in accordance with the understanding of disability in GBD; secondly, based on gross national product (GNP) and different age groups in the creation of social value. The different productivity weights given in the calculation of the indirect economic burdens of different age groups were calculated, and finally the indirect economic burden of the total population was calculated. Conclusion The method of combining DALY with human capital method to estimate the indirect economic burden is a more reasonable method at present, but the calculation of DALY is difficult.
