[BDSP. Notice produite par INIST-CNRS 8nqR0xGG. Diffusion soumise à autorisation]. The present study aims to evaluate the impact of cost-effectiveness information on clinical decision making using discrete choice experiment (DCE) methodology. Data were collected through a self-completed questionnaire administered to Italian cardiologists in June 2007 (n=129 respondents, 1143 observations). The questionnaire asked clinicians to make choices between paired scenarios, across which three key dimensions were identified and varied : (1) quality of clinical evidence, (2) size of health gain (reduction of relative and absolute risk), and (3) economic impact (incremental cost-effectiveness ratio). A random effects probit model was used to estimate clinicians'preferences for the different dimensions, while the heterogeneity of preferences was tested in a model with interaction terms. Dominance tests were used to assess the consistency of responses. The results indicate that Italian cardiologists regard economic impact (cost-effectiveness) as an important factor in their decision making. Economic evidence is valued more highly among clinicians with a higher self-assessed level of knowledge regarding economic evaluation techniques, as well as among younger professionals (age
