Discrete Choice Experiments to Elicit Patient Preferences for Decision Making in Transplantation

Providing care for transplant recipients is challenging given the need to maintain optimal graft function and survival while managing the debilitating side effects and complications associated with immunosuppression including infection, cancer, new-onset diabetes mellitus, and cardiovascular disease. Given the complexity of treatment options and the uncertainty about long-term benefits and harms of treatment, understanding patient preferences and values are key to ensuring that clinical decisions take into consideration patient priorities to support shared decision making and self-management. Choice experiments are increasingly used to quantify patient and community preferences, including in the field of transplantation. Discrete choice experiments (DCEs) are a well-established, validated methodology used to elicit preferences for decision making in health and other settings. In transplantation, for example, DCEs have been used to elicit patient preferences for outcomes following kidney transplantation, to identify community preferences factors for organ allocation and in establishing core outcomes. This article provides an overview of the concepts and methods used in the design of DCEs and how patients' preferences can be applied in shared decision making in transplantation.
