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.

Primary Outcome Measures:
  • Total wait time for surgery [ Time Frame: September 2010 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Surgery rates determined by the proportion of patients who proceed to surgery within 2 years [ Time Frame: September 2010 ] [ Designated as safety issue: No ]
  • Decision quality, the extent to which patients decisions are informed and values-based [ Time Frame: September 2010 ] [ Designated as safety issue: No ]
  • Cost effectiveness (including estimated effects on quality adjusted life expectancy and costs) [ Time Frame: September 2010 ] [ Designated as safety issue: No ]

Patient decision aid and referral onward
Behavioral: Patient decision aid and referral onward.

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).
