Analysis, otherwise usefully called cost-utility analysis (CUA) or cost-effectiveness analysis (CEA) where the decision criterion is 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 and who apparently believe that, if they rename it, the problem is solved. Actually the problem becomes worse, for we now have to ask whether cost-per-QALY analysis is a subset of CEA, CUA or CBA. It is not compulsory, fortunately, to answer this question.
