Incremental Cost-Effectiveness Ratio
The ratio of the difference in costs to the difference in effects between two healthcare interventions.
Definition
The ICER is calculated as the difference in total costs divided by the difference in total effects (typically QALYs) between a new intervention and a comparator. It represents the additional cost per additional unit of health outcome gained. Decision-makers compare the ICER against a willingness-to-pay threshold to determine cost-effectiveness.
