2013年1月2日 · The QALY is a quasi-scientific measure designed to prioritize health and social services (French 2004a). The QALY method entails multiplying each year of life of a person who survives an illness or injury by a fraction that expresses the impairment of quality of life believed to be experienced by that person (Walsh 1993).

2009年3月1日 · 7. Each individual is risk neutral with respect to longevity and has utility that is additive across time. 8. Value scores (preferences) measured across individuals can be aggregated and used for the group 9. QALYs can be aggregated across individuals; i.e., a QALY is a QALY regardless of who gains/loses it QALY, quality-adjusted life-year.

2018年8月1日 · The QALY concept was weakly integrated until the 1970s, with non-academics and those outside Rosser and Watt's network of researchers unaware of their ideas. This may be linked to the absence of a network such as the Health Economists' Study Group (HESG) which, from 1972, brought together academics, government economists and others into sharing ...

2023年1月1日 · Our approach builds upon the framework introduced in Hougaard et al. (2013).Therein, a number of population health evaluation functions, such as the (time linear) QALY and HYE (acronym for Healthy Years Equivalent) population health evaluation functions, concerned with the accumulation of health, are characterized axiomatically.

The QALY is a measure of the impact of a disease, which includes life length and life quality. It ranges from 1 (year in perfect health status) to 0 (equivalent to death). 29,30 For QALY estimation different elements are considered, the main one being the assignation of preference values for the different health status, also known as utilities ...

2024年6月1日 · The quality-adjusted life year (QALY) is over 50 years old. 1 Debate about the ethical basis for the QALY and its use in cost-effectiveness analysis (CEA) and policy decision making are almost as old(for example, see Harris, 2 Rawles, 3 and responses from Mooney, 4 and Williams 5). These (and other) early articles are worth rereading.

2020年3月1日 · QALY gains (the averages of QALY gain per person receiving the treatment) were informed by the range generally considered by HTA committees (drawing on interviews with decision makers in Phase II of the qualitative work) and the literature, and ranged from 0.01 of a QALY to 4 QALYs.

2022年3月1日 · With the QALY as a concept now entering its sixth decade, it is useful to reflect on the work of Bush, Fanshel and Torrance: first, to understand their contribution in a historical context (i.e. what motivated the development of the QALY); secondly, to understand the impact of their research on shaping subsequent developments (both theoretical ...

2017年3月1日 · An economic evaluation takes the QALY gains from an intervention (‘incremental QALYs’) and compares them to the incremental costs of an intervention (relative to a comparator). This produces an incremental cost effectiveness ratio …

1993年9月1日 · The QALY is a general outcome measure which can be used in assessing clinical decisions, public health initiatives, the outcomes of clinical trials and the impact of new technologie~.~ Measurement The essential feature of the QALY approach is the assignment of weights (quality adjustments) to differ- ent health states.
