This study is a 2X2 factorial randomized trial that will the examine the comparative effectiveness of two patient decision aids for hip and knee osteoarthritis (OA) as well as the impact of a surgeon-focused intervention.
This study is a 2X2 factorial randomized trial that will examine the comparative effectiveness of different decision support strategies for patients making treatment decisions about hip or knee osteoarthritis (OA). Eligible patient subjects will be randomly assigned to receive one of two decision aids before their upcoming clinic visit with a participating orthopedic specialist. Participating providers are randomly assigned to either usual care or an intervention (a report that includes patients' goals and treatment preferences). Patient participants will complete three surveys at different time points: before their orthopedic visit, one week after the clinic visit, and 12 months later. Providers will complete a short survey for a subset of patient participants. The study is titled the DECIDE-OA study.

Patients Knowledge
Knowledge sub-score generated from responses to the Hip or Knee Decision Quality Instrument (DQI). Scores range from 0-100%, with higher score meaning higher knowledge.
Time frame: before orthopedic visit
Percentage of Patients Who Received Preferred Treatment
Patient preferred treatment item from the Hip or Knee Decision Quality Instrument will be compared with the treatment received to determine percentage of patients who received treatment that matched their preferences.
Time frame: 1 week after visit with orthopedic surgeon
Percentage of Participants Who Used the Decision Aid
1 item asking patients how much they reviewed the program (none, some, most, all). The percentage who report viewing most or all will be calculated.
Time frame: before orthopedic visit
Change in Quality of Life
Overall quality of life (EQ-5D) scores will be calculated and the impact of decision support strategies on change in quality of life will be examined. Scale ranges from -0.11 to 1.00, with higher (positive) values meaning better overall health. The minimum important change is 0.10 points.
Time frame: before orthopedic visit; 12 months from date of orthopedic visit
Surgical Rates
Medical chart review and patient report of whether or not surgery was used in the 6 months after the visit.
Time frame: 6 months after the initial visit
