Cost-per-QALY Analysis

Definition

Health Economics

  • A specific form of cost-utility (CUA) or cost-effectiveness analysis (CEA) where the decision criterion relates to cost per quality-adjusted life-year (QALY). The term appears to have been invented by taxonomizers who are unsure whether CUA is a subdivision of CEA or of cost-benefit analysis but it is not clear that a mere renaming resolves that issue. Actually the problem seems to have become worse, for we now have to ask whether cost-per-QALY analysis is a subset of CEA, CUA or CBA. There is also the prospect of there being a new kind of 'analysis' for every outcome measure employed. It is not compulsory, fortunately, to answer this question.
