  1. Incremental cost-effectiveness analysis : The optimal strategy depends on the strategy set.

    Article - En anglais

    Evaluating the incremental cost-effectiveness of a technology is critical to understanding the impact of its adoption.

    The purpose of this study was to evaluate, using a particular example, how the specific alternatives selected for a cost-effectiveness analysis may influence the results of the analysis.

    In this example, we analyzed the incremental cost-effectiveness of estriol screening for Down syndrome.

    Model assumptions of expected costs and effectiveness were based on previously published work involving four clinical strategies, including a « do nothing » (no screening) strategy.

    When the analysis started with all four strategies, two of the strategies could not be considered cost-effective because of extended dominance.

    However, when we eliminated the « do nothing » from the strategy set because of its clinical irrelevance, all three remaining strategies might be considered cost-effective from a policy perspective.

    We concluded that the incremental cost-effectiveness of clinical strategies could be strongly affected by the starting point for the analysis.
