Implementation of a Decision Aid for Hip and Knee Osteoarthritis in Orthopedics: A Mixed-Methods Process Evaluation.

Background: In orthopedics, the use of patient decision aids (ptDAs) is limited. With a mixed-method process evaluation, we investigated patient factors associated with accepting versus declining the use of the ptDA, patients' reasons for declining the ptDA, and clinicians' perceived barriers and facilitators for its use.

Methods: Patients with an indication for joint replacement surgery ( = 153) completed questionnaires measuring demographics, physical functioning, quality of life (EQ-5D-3L), and a visual analog scale (VAS) pain score at 1 time point.
