 Another reason for the stalemate is the aggregation problem as applied to the “benefit” side of the CEA calculation. Some have argued that we should abandon the QALY and DALY, summary health measure technology entirely (Anand &amp; Wailoo 2000), while most agree with Dan Brock that health care prioritization without any reference to quality of life is a non-starter (Brock 1995). There have been some attempts at finding a workable multi-criteria approach in which health benefits are disaggregated into separate components (Baltussen &amp; Niessen 2006), but such suggestions open the door to the so-called “indexing problem” (discussed later in the context of disability) of trying to sum up disparate and incommensurable benefits (income, happiness, social productivity, creativity) in a way that would allow us to compare two health outcomes. Attempts at direct head-to-head comparisons between health outcomes require the dubious methodological assumption that health is unidimensional: walking out of the hospital with one surviving hand is obviously better than with none; but is being left partially sighted better, or worse, than ending up in a wheelchair? How do we compare various domains of human functioning that, together, make up the state of health?
