In a context of increasingly limited resources, a number of strategies, such as the adoption of decrementally cost-effective interventions (d-CEIs), could offer potential levers at enhancing both efficiency and equity in healthcare systems. In this paper, we investigate policy-makers’ willingness to adopt d-CEIs using a two-stage pairwise choice experiment survey eliciting preferences for d-CEIs’ attributes in forced choices and the determinants of d-CEIs’ adoption (unforced choices). We investigate the effect (and trade-offs) between three attributes: health loss, reversibility (possibility to switch back to usual care), and cost-savings. Such trade-offs are contextualized by using two sensitivity attributes: disease severity and savings uncertainty. Our final sample consists of 180 decision-makers from various EU countries.
All attributes’ levels have a significant effect in both stages. The ”health loss” attribute dominates in the first stage decision-makers would require 28.3% increase of budget savings to be indifferent between a scenario of small versus significant health losses. In contrast, the ”reversibility” attribute dominates in the second stage suggesting that anticipated regret may play a role in adoption decisions. Sensitivity analyses reveal the existence of heterogeneity across respondents in both stages. Our analyses provide original results regarding the inter-individual determinants of policy-makers’ willingness to adopt d-CEIs.
