An overview is presented of the use of cost-effectiveness analysis in healthcare resource allocation decision-making. Threshold figures (i.e. cost per unit of health gain) currently proposed for, or applied to, resource-allocation decisions are reviewed. Disability Adjusted Life-Years (DALY) are mentioned. A table of data provides a summary of cost-effectiveness thresholds and CE ratios in terms of either QALYs (quality-adjusted life-year) or LYGs (life-year gained). Threshold figures and evolution of thresholds are discussed.
