African American Preference for Knee Replacement: A Patient-Centered Intervention

Study Overview
=================
Brief Summary
-----------------
A randomized, controlled design will be utilized to examine and compare the effectiveness of the proposed educational intervention, which includes an educational decision aid with attention control on select key patient-centered and process of care outcomes. The study sample will consist of approximately 300 African-American patients with osteoarthritis (OA) of the knee. Patients will be recruited from Pennsylvania Presbyterian Medical Center and the Philadelphia VA Medical Center and will be randomized to one of the two study arms. The immediate goal of this randomized controlled trial is to assess the effect of a high-quality, evidence-based, patient-centered educational intervention on African American patient preferences, expectations, and the likelihood of receiving a recommendation for knee joint replacement surgery when clinically indicated. The long-term goal of this research is to implement effective strategies to improve minority patients' access to joint replacement and ultimately eliminate racial disparities in the utilization of this effective treatment for knee OA. Study Aim: To examine the effect of the decision aid (DA) intervention on the likelihood of receiving a recommendation for knee joint replacement when clinically indicated. Hypothesis: The DA intervention will lead to higher rate of treatment recommendation within 6 months. Secondary Aim: To examine the effect of the DA intervention on the rate of knee replacement receipt within 12 months. Hypothesis: Patients randomized to receive the intervention will undergo knee replacement within 12 months at a higher rate than those in the attention control group.

Detailed Description
-----------------
The study involves a baseline questionnaire, educational intervention, and follow-up questionnaire by phone 12 months after the intervention takes place. All eligible, consented patients will complete the baseline questionnaire, conducted by an ACTION research staff member. The baseline questionnaire (attached at end of protocol) will include the following instruments that have been field-tested by our team in previous and ongoing studies: 1.) Willingness to Consider Joint Replacement Question 2.)Knowledge Regarding Knee OA and Joint Replacement (developed by The Foundation for Informed Medical Decision Making) 3.) Hospital for Special Surgery Knee Expectations Survey 4.)Socioeconomic Survey 5.) Access to Health Care, Charlson Comorbidity Index 6.) Quality of Life Shortened Form-12v2. This survey can be done over the phone or in person. It should take approximately 30-40 minutes. At the completion of the baseline questionnaire, patients will be randomized into either study Decision Aid (DA) (hereafter referred to as DA intervention) arm or the attention control arm. Patient appointments for the DA intervention or attention control activity will be scheduled to occur 2 weeks prior to the patients appointment with an orthopedic specialist (up to the date of the appointment). The DA intervention (referred to as an information session in patient material) will be completed by an ACTION research study interventionist (the interventionist will not administer the baseline assessment). In the intervention arm, patients will be shown a decision aid video entitled, Treatment Choices for Knee Osteoarthritis. The patients are then given a brief education intervention called AskMe3, which is a brief communication skill-building intervention developed by the Partnership for Clear Health Communication. AskMe3 instructs patients 3 questions to ask their doctor: a) what is my main problem b) what do I need to do c) why is it important for me to do this? The completion time for the educational intervention will be approximately 1 hour. The attention control arm will be conducted by the ACTION research staff. Patients will be given written educational material adapted from the NIH/National Institute of Arthritis and Musculoskeletal and Skin Diseases publication Osteoarthritis to review at his/her leisure. (A copy of the information contained in the informational pamphlet is attached at end of protocol). The completion time for the attention control arm is approximately 10 minutes. Follow-up procedures will occur at the following time points: 1.) approximately 6 months after the participants intervention, an ACTION team staff member will review their medical chart to see if the participant had knee joint replacement surgery 2.)12-months post intervention participants will be contacted to find out if they had knee joint replacement surgery and a medical chart assessment will occur at this time as well. All follow-up procedures will be administered by an ACTION research team member that was not involved in the educational intervention. Participants in both the DA intervention and the attention control will complete a 12-month follow-up (completed approximately 12 months post intervention)survey over the phone. The survey will be comprised of the following: Willingness to consider joint replacement, Hospital for Special Surgery Knee Expectations Survey, Knowledge Regarding Knee OA and Joint Replacement, and a survey regarding surgery for joint replacement. At the time of the 12-month follow-up, the patient's medical record will be accessed to check for a joint replacement procedure.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| No Intervention: Attention control<br>Subjects randomized to the attention control arm will receive an educational program (an NIH-developed booklet) that summarizes how to live with knee OA but does not specifically mention joint replacement. This booklet provides information about OA, examples of exercises one could do to improve pain and reduce stiffness, types of non-drug pain relief such as massage, and information about various medications. The interventionist will give the participant the booklet and describe what can be found inside. They are also encouraged to ask their doctor any questions they may have about the information in the booklet or questions they may have about their OA. The purpose of this educational program is to provide a tangible clinical incentive to the control group for participating in this additional component of the study. | |
| Experimental: Decision Aid (DA) Intervention<br>Patients randomized to the DA Intervention will watch a Knee OA Decision Aid (DA) developed by the Foundation for Informed Medical Decision Making and then receive a brief counseling session called AskMe3. The DA is a video that provides viewers with information about OA, treatment choices such as lifestyle changes, non-drug treatments, medication, injections, complementary therapies, and surgery, as well as the pros and cons of each type of treatment. The AskMe3 is a communication, skill-building intervention, which instructs patients to ask 3 questions to the doctor: 1) What is my main problem? 2) What do I need to do? 3) Why is it important for me to do this? | Behavioral: Decision Aid (DA) Intervention<br>* Patients randomized to the DA Intervention will watch a Knee OA Decision Aid (DA) developed by the Foundation for Informed Medical Decision Making and then receive a brief counseling session called AskMe3.
