Not all “quality-adjusted life years” are equal
Journal of Clinical Epidemiology, 2007There is evidence that utility elicitation methods used in the calculation of quality-adjusted life years (QALYs) yield different results. It is not clear how these differences impact economic evaluations.Using a mathematical model incorporating data on efficacy, costs, and utility values, we simulated the experiences of 100,000 hypothetical rheumatoid

Methods for quality adjustment of life years
Social Science & Medicine, 1992Several valuation techniques are in use for quality adjusting life years in cost utility analysis. The paper gives an overview of the variability in results. A close inspection of a number of instruments with respect to their theme, instructions, decision framing and the phrasing of questions make many of the observed differences in results ...

The importance of Perspective in the Measurement of Quality-adjusted Life Years
Medical Decision Making, 1997Scaling instruments for the measurement of quality-adjusted life years (QALYs) incor porate either a personal or an impersonal perspective on the benefits of a health intervention and either do or do not incorporate considerations of equity. This paper sets out three hypotheses concerning perspective and equity: 1) that more equally distributed ...

This type of analysis is used widely in Europe and is being used increasingly in the United States. This article provides an overview of cost utility analysis and quality adjusted life years, a commonly used effectiveness ...

quality-adjusted life-years (QALY)
2009syn. healthy-year equivalent (HYE); QALYs are calculated by multiplying the time spent in each health state by the value assigned to the particular health state; to calculate QALYs, numerical judgments of the desirability of various outcomes must be determined; these values are called “utilities” (with values between 0-death and 1-perfect health; very ...
