A major goal of decision support tools (decision aids [DAs]) is to help people make informed decisions; hence, they often provide users with important information. This is particularly true for medical shared decision-making tools (decision aids [DAs]) for surrogate-decision-makers. These tools are designed to help individuals make crucial life-or-death decisions for loved ones who, due to a severe illness, are unable to make their own decisions. Making such decisions on behalf of a loved one often requires the processing of a great deal of medical information, typically in a short period of time, while respecting the patient’s values and preferences. Hence, it is particularly important to design such DAs in a way to communicate provided information effectively.
