β¦ Synopsis
Statistical and conceptual difficulties complicate the estimation of the incremental cost-effectiveness ratio (ICER). An alternative approach is to measure cost-effectiveness by the incremental net health benefit (INHB), defined as the difference in mean effectiveness of a new treatment compared with a standard, adjusted for cost difference by subtracting the health foregone if purchasing care at the rate of a marginally cost-effective therapy. Because net health benefit (NHB) is dependent on this threshold rate, one can construct confidence intervals for the INHB at various values of the rate. It turns out that the set of rates where new and standard are not significantly different is equal to the Fieller's method confidence set for the ICER. We review the derivation of the Fieller's method confidence set, present numerical examples, and discuss the implications of our result for the calculation and interpretation of NHB analyses.

## Abstract Statistical methods are given for producing a costβeffectiveness frontier for an arbitrary number of programs. In the deterministic case, the net health benefit (NHB) decision rule is optimal; the rule funds the program with the __largest positive__ NHB at each __Ξ»__, the amount a decis
## How important is the accuracy of your health care cost trend estimates? For most companies, the difference between the assumed health care cost trend rate and the actual increase may not largely affect postretirement cost and reported net income. But the authors found that for some companies the
Both incremental cost-effectiveness ratios and net benefits have been proposed as summary measures for use in cost-effectiveness analyses. We present a unifying proof of the optimality and equivalence of ICER-and net benefit-based approaches to the health resource allocation problem, including both
This paper reviews the argument advanced by Parsonage and Neuburger that the non-monetary benefits of health programmes should be discounted at a lower rate than that used for financial flows. The conceptual issues raised in that paper are discussed and others, such as the tradability of non-monetar
