Estimating CE Ratios under Second-order Uncertainty

Aaron A. Stinnett and A. David Paltiel

Medical Decision Making, 1997, vol. 17, issue 4, 483-489

Abstract: Two methods have been presented for estimating cost-effectiveness ratios under con ditions of second-order (model) uncertainty: one method estimates a mean ratio of cost to effect (the "mean ratio" approach), and the other estimates a ratio of mean cost to mean effect (the "ratio of means" approach). However, the question of which estimate is theoretically correct has not been formally addressed. The authors show that the "ratio of means" approach follows directly from the theoretical foundations of cost-effectiveness analysis, has attractive internal consistency properties, and is con sistent with a simple vector algebra approach to the problem. In contrast, the "mean ratio" approach has not been shown to follow from first principles, is internally incon sistent, and can prescribe economically inefficient choices. It is concluded that the "ratio of means" procedure should be preferred unless persuasive arguments are pre sented to the contrary. Key words: cost-effectiveness analysis; mean ratio; ratio of means; second-order uncertainty. (Med Decis Making 1997;17:483-489)
