Cost-Effectiveness Acceptability Curve

Definitions

Health Economics

  • A cost-effectiveness acceptability curve (CEAC) is a graphical, Bayesian, way of showing more information about uncertainty in a cost-effectiveness analysis than can be done by using only confidence intervals. It can also be used in comparisons of more than two interventions. The curve shows the proportion of estimates of the incremental cost-effectiveness ratios (ICERs) that are lower than a variety of possible incremental cost- effectiveness ceiling ratios or thresholds. It thus provides a visual image to aid judgments as to whether a technology actually is cost-effective. The curve typically has a convex section fol lowed by a concave section, with a point of inflexion.
