QALYs, Disability Discrimination, and the Role of Adaptation in the Capacity to Recover: The Patient-Sensitive Health-Related Quality of Life Account.

Abstract

Quality-Adjusted Life Years (QALYs) and Disability-Adjusted Life Years (DALYs) are two of the most commonly used health measures to determine resource prioritization and the population burden of disease, respectively. There are different types of problems with the use of QALYs and DALYs for measuring health benefits. Some of these problems have to do with measurement, for example, the weights they ascribe to health states might fail to reflect with exact accuracy the actual well-being or health levels of individuals. But even if these weights represent accurately the well-being levels of individuals, there is room for questioning whether these measures capture everything that we care about in these cases, or whether there are important issues that they leave out, including considerations of fairness or equality. In this regard, the measures have been criticized for treating the aggregation of small benefits as greater than the aggregation of fewer but bigger benefits,1 for disregarding fair chances in favor of utility maximization,2 and for raising problems when applied in the context of variable population size.3 Perhaps one of the most pervasive ethical issues that has been associated with the use of these measures is the fact that they seem to discriminate against disabled people.4 Since the measures assume that disabled people have lower well-being and a shorter life span, treating a disabled person's medical condition contributes less to the maximization of years of life with good health than treating a non-disabled patient's medical condition.
