Disability weights in the global burden of disease 2010 study: two steps forward, one step back?

Vast Majority Of Development Assistance For Health Funds Target Those Below Age Sixty

“…17 A final explanation relates to age variation in economic activity and the potential to be a caretaker or family breadwinner, 18 which is a reason why results from some of the earlier versions of the Global Burden of Disease Study attributed lower weight to older adults. 19 …”

Сriteria of efficiency in pharmacoeconomic analysis

“…Several alternative tools were developed to assess the duration and quality of life -QALY (Quality adjusted life year), HYE (Health Year Equivalent), HLY (Healthy Life Years) and DALY (Disability Adjusted Life Year). Indicators of QALY, HYE and HLY make common sense and demonstrate life expectancy of good quality, while DALY has the opposite meaning, a lifetime with negative quality and potential years of life lost [7][8][9][10][11][12][13][14].…”

The use of potential years of life lost for monitoring premature mortality from chronic diseases: Canadian perspectives

“…18 The conceptual and methodological framework underlying DALY has been heavily criticized with regard to the choice of assumptions, particularly the disability weights, and underwent its first major revision in 2012. 17,18 However, the key weakness around the determination of disability weights in the calculation of YLD remains controversial and is the chief reason why a recent Canadabased assessment of the revised methodology suggested that the utility of DALY for guiding public health policy is limited at best. 17 While DALY remains the choice indicator at the international level, in Canada DALY was not included in the set of comparable health indicators and therefore has not been routinely monitored.…”

“…YLD is weighted for the severity of a condition by the so-called disability weights, which reflect the relative reduction in health-related qualify of life. 17 The quality of YLD estimates directly depends on the underlying assumptions about the disability weights and the availability of nationally representative, complete, consistent and comparable incidence or prevalence data. 16,18 Large variations in methodological choices around the underlying assumptions and the quality of epidemiological data render it difficult to assess whether differences in DALY estimates are due to actual differences in population health.…”
