Title: Feasibility Study: Does Screening Plus Patient Decision Aids Reduce Unnecessary Surgical Referrals for Total Joint Arthroplasty in Practices With Long Waiting Lists for Surgical Consults?
Brief Summary: Ministries of Health consider wait lists for total joint replacement a top priority. Research priorities to manage wait lists indicate the need to establish benchmarks that consider patient preferences. However, patients' preferences for hip or knee replacements are strongly associated with their misperceptions of the indicators for, and the risks and benefits of, these procedures. These misperceptions can be corrected with the use of patient decision aids. When decision aids are used in combination with assessing surgical eligibility, there may be a reduction in unnecessary referrals for surgery either because the patient is ineligible or because the eligible candidates make informed decisions to forgo this option.

The study objective is to pilot test the feasibility of a trial evaluating the effects of patient decision aids on reducing unnecessary surgical referrals for total joint replacement, when used in combination with a general practitioner run clinic to screen patients with hip or knee osteoarthritis for surgical eligibility.

The investigators expect to provide evidence of feasibility (e.g. ease of recruiting patients, delivering the interventions, measuring patient outcomes) and sample size needed for a larger scale study. This study should also provide evidence for planning implementation of the interventions and standardized training across other centers.
