The Effect of Review of a Decision Aid Prior to the Appointment on Decisional Conflict Compared to Usual Care in the Treatment of Trapeziometacarpal (TMC) Arthritis

"Cohort I will be managed with a decision aid (henceforth DA), and Cohort II will be managed without one. The patients in Cohort I will receive the DA, which they can complete in a separate room and take home. The decision aids include information on the disease/condition, treatment options, benefits, risks, scientific uncertainties, and probabilities of potential outcomes tailored to the patient's health risks factors. Additionally, it includes values clarifications such as describing outcomes in functional terms, asking patients to consider which benefits and risks matter most to them, and guidance in the steps of decision making and discussing their decision with family/friends. It is interactive and dynamic, helping patients clarify their preferences and come to a decision that feels best to them."
