90 patients with trapeziometacarpal (TMC) joint arthritis and scheduled for a first time visit to a hand surgeon were randomized to receive usual care with either an additional decisional aid or no decisional aid. The primary outcome of interest was the Decisional Conflict Score. Secondary outcomes of interest included Quick Disability of the Arm, Shoulder and Hand (QuickDASH) score, pain intensity on a numerical rating scale, the Physical Health Questionnaire (PHQ-2), patient satisfaction with the visit and with treatment, consultation time, decisional regret scale, and the Consultation and Relational Empathy (CARE) score. Follow up was performed at 6 weeks and 6 months post-appointment. The results found a significantly lower score for decisional conflict score in the decision aid group compared to the usual care group. Otherwise, no significant differences in all remaining outcomes were observed.
