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 primary study objective is to evaluate the effect of patient decision aids (PtDAs) on total wait times (wait times for surgical consultation, plus wait times for surgery) when used in combination with a general practitioner run clinic to screen patients with hip or knee osteoarthritis for surgical eligibility. Major secondary objectives include determining (a) the effect of PtDAs on surgery rates within two years, (b) the effect of PtDAs on decision quality, and (c) cost-effectiveness of PtDAs for total joint arthroplasty.

Interventions

Type	Name	Description
BEHAVIORAL	Patient decision aid	Patients will receive i) Patient education:usual take home education brochure from recruiting hospital ii)a video/DVD PtDA for either hip (Treatment choices for hip osteoarthritis) or knee (Treatment choices for knee osteoarthritis) © Health Dialog 2005. iii) a personal decision form:an interactive form used by patients after the DVD to elicit their knowledge, values, preferred option, and perceptions of the decision making process. iv) Referred onward to the surgeon with their preferences for surgery using a standardized report of their clinical findings plus decisional data (knowledge, values, preference).
BEHAVIORAL	Usual care	Patients will receive i) the usual take-home educational brochure available at the recruiting hospital describing preparation for surgery after the decision is made, recovery after surgery, and discharge plans. ii) Referral onward to surgeon with a standardized report of clinical findings only
