A recent nationwide survey of physicians conducted in the United States showed that almost half of them receive requests from patients for an unnecessary test or procedure at least once a w'eek. Three in ten said this happens at least several times a week {Choosing Wisely®, 2014). Patients might need tools that help them better understand evidence-based recommendations and that support them in demanding high-quality and good-value care. Yet presently too few' decision aids are available for patients. The campaign was launched in the United States, but has since expanded to more than ten countries. It is hoped to be effective by educating both patients and their doctors, and by facilitating a discussion between them that assists in decision making.
