Decision aids are interventions or tools designed to facilitate shared decision-making and patient participation in health care decisions.
Decision aids help patients think about choices they face; they describe where and why choice exists; and they provide information about options, including, where reasonable, the option of taking no action. This can help patients to deliberate, independently or in collaboration with others, about the available options. Decision aids are most commonly pamphlets, videos, or web-based tools.
Decision aids are distinct from traditional educational materials as they focus on presenting alternatives, detailing the associated risks and benefits, including explicit probabilities, and tailoring information to individual patients. To support shared decision-making, evidence-based patient decision aids (ptDAs) have been created.
