Cost effectiveness is usually measured using metrics such as Quality-Adjusted Life Years (QALYs) and Incremental Cost-Effectiveness Ratios (ICERs). QALYs take into account both the quantity and quality of life gained from a treatment. ICERs compare the difference in costs and health outcomes between two treatments. Lower ICERs indicate more cost-effective treatments. These metrics help inform decisions on whether a treatment should be adopted widely.
