ADJUSTED LIFE YEARS Meaning and
Definition
-
Adjusted Life Years (ALY) refers to a quantitative measure used in health economics and outcomes research to estimate the impact of disease and disability on an individual's lifespan. It is a composite metric that takes into account both the quantity and quality of life experienced by a person.
ALY is calculated by multiplying the number of years lived with a disability (YLD) by a disability weight, and then adding the number of years of healthy life lost due to premature death (YLL) due to the disease or condition under consideration.
The disability weight represents the severity of the illness or disability on a scale from 0 (perfect health) to 1 (death), capturing the reduction in overall well-being caused by the condition. YLD accounts for the years lived with a disability while YLL considers the number of years a person would have lived had they not died prematurely.
Adjusted Life Years provide a comprehensive perspective on the burden of disease by quantifying the impact of both morbidity and mortality. This measure allows researchers and policymakers to compare the health outcomes of different populations, evaluate the effectiveness of interventions, and prioritize healthcare resource allocation based on the disease burden.
ALY is frequently used in cost-effectiveness analysis and health technology assessments to inform decisions about healthcare resource allocation and to evaluate the impact of healthcare interventions on population well-being. By providing a standardized measure of health impact, ALY contributes to evidence-based decision-making in healthcare policy and resource allocation.
