Experimentos de elección discreta. Diseño, análisis e implementación en salud

Discrete choice experiments (DCE) are a methodology for evaluate patient preferences for health-related outcomes or inter-ventions. Other preference measurement techniques that use simple methods of choice or basic statistical tools that fail to evaluate the specific benefits of an intervention, delivery process, benefit, satisfaction and patients’ preferences in terms of time, quality or specific attribute. The DCE combine in the generation of attributes and mathematical modeling, complex task of designing and execution, to improve the quality and optimize the necessary amount of information, achieving an efficient use of resources with excellent quality results. This document presents globally a brief of the history, development and theo-retical foundation of the DCE and then presents in a critical way the potential limitations, precautions in their use and implementation that allow to establish the possible scenarios of use and development.
