  Purpose

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.

  • Decision quality [ Time Frame: June 2008 ] [ Designated as safety issue: No ]
  • Satisfaction with preparation for decision making [ Time Frame: June 2008 ] [ Designated as safety issue: No ]
  • Proportion of unnecessary surgical referrals [ Time Frame: April 2009 ] [ Designated as safety issue: No ]

Enrollment: 142
Study Start Date: January 2007
Study Completion Date: April 2009
Primary Completion Date: April 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Patient decision aid
Patient decision aid about treatment options for osteoarthritis
Behavioral: 1 Patient decision aid

Patients will receive:

i)patient education booklet 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 is an interactive form used by patients after the DVD to elicit their knowledge, values, preferred option, and perceptions of the decision making process.

iv) Referral to the surgeon with a standardized report of their clinical findings plus decisional data (knowledge, values, preference).

Behavioral: 2 Usual care

Patient will be given i) education booklet from local hospital which is a standardized teaching booklet given to all patients describing preparation for surgery, recovery after surgery, discharge plans.

ii) Referral to the surgeon with a standardized report of their clinical findings.
