About this study

Total joint arthroplasty (TJA) is an effective procedure for reducing pain and improving function in patients with disabling osteoarthritis (OA) of the hip or knee. However, as with all invasive procedures, TJA is associated with certain risks and substantial costs. Since the indications for TJA are heavily dependent on patients' quality of life and expectations. TJA utilization rates vary widely throughout the United States, as seen with other 'preference-sensitive' procedures. Early evidence suggests shared decision making (SDM) strategies are effective in enhancing patient decision quality, or the degree to which treatment decisions reflect the preferences of fully informed patients, especially for preference-sensitive procedures like TJA. Despite these advantages, however, SDM has not been embraced or widely adopted in orthopaedics. To investigate this limited uptake, the investigators propose a series of evaluations of individual-level strategies. The investigators innovative and unique contribution is to approach patients, surgeons and healthcare purchasers as having symmetric and equally valid concerns about the benefits and cost associated with SDM. The investigators overall objective is to facilitate wider dissemination of SDM strategies in orthopaedic practices. The specific aims of the project are to assess, for SDM strategies, the impact on key patient, surgeon, and healthcare purchaser priorities; By achieving this aim our project will produce new interventions and incentives for disseminating SDM that are endorsed as feasible and acceptable by a coalition of patients, surgeons, and purchasers. The investigators plans for evaluation include a randomized controlled trial to evaluate the impact of SDM on outcomes of interest to patients, surgeons, and purchasers.

Read the detailed description

We propose an RCT based on a non-randomized pilot study conducted at UCSF that included 115 patients who were referred for evaluation of hip and knee OA. The results of this pilot study suggested that DESI's were associated with greater patient knowledge, higher decision quality, higher patient and surgeon satisfaction, and no substantial impact on length of office visit or treatment decision. As in the pilot study, the RCT intervention will include a package of decision and communication aids shown in prior studies to increase patient knowledge, question-asking, and information recall. The intervention includes digital video discs and booklets produced by the Foundation for Informed Medical Decision Making and Health Dialog; a question-prompting phone call with a trained health coach; audio-recordings of the patient-surgeon consultation; and a copy of the surgeon's dictated note. The control arm will consist of usual care. Our primary outcome is the proportion of patients who arrive at an informed decision during the first visit. This outcome is of interest to patients, surgeons and healthcare purchasers, all of whom value efficiency and quality in delivery of care. Our hypothesis is that a higher proportion of patients in the intervention group will arrive at an informed decision during the first visit, as a result of being more knowledgeable and prepared for their visit, thus conserving resources while advancing quality. Secondary outcomes of interest will include treatment decision (e.g., surgical vs. non-surgical); patient and provider satisfaction; length of office visits; and adherence to treatment recommendations.

We will assess whether patients are informed or not using a survey instrument testing 19 consensus "key facts" developed by FIMDM based on evidence and expert opinion. We will measure whether patients arrive at a decision using the Stage of Decision Making instrument. We will administer both instruments immediately after the patient's first consultation with their surgeon.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Stage of decision making

    We will measure the proportion of patients who will arrive at a more informed decision during the clinic visit through surveys administered before the clinic visit and immediately after the clinic visit. We will ask patients before the clinic visit what treatment decision they are leaning towards, how far along they are with this decision. We will ask patients after the clinic visit, what treatment they want and how far along they are with the decision.

    Measured: Participants will be followed for the duration of the clinic visit, expected to last up to 4 hours

  2. Knowledge Score

    We will assess whether patients are informed or not using a survey instrument testing 19 consensus "key facts" developed by the Foundation for Informed Decision Making (FIMDM) based on evidence and expert opinion.

    Measured: Participants will be followed for the duration of the clinic visit, expected to last up to 4 hours

Secondary outcomes (4)
  1. Treatment Decision

    Patients will be asked in a questionnaire what treatment decision (surgical vs. non surgical) they chose immediately after their clinic visit.

    Measured: Participants will be followed for the duration of the clinic visit, expected to last up to 4 hours

  2. Patient and Surgeon Satisfaction

    Patients will be asked in the questionnaire to rate on a scale of 0-10, with 0 being lowest satisfaction, and 10 being highest satisfaction, how satisfied they were with the consultation. Surgeons will be asked, to rate on a scale of 0-10, how appropriate the content of the patient's questions were, how appropriate the number of the patient's questions were, how satisfied the surgeon was with the efficiency of the consultation, and overall satisfaction of the visit. Both surveys will be administered immediately after the clinic visit.

    Measured: Participants will be followed for the duration of the clinic visit, expected to last up to 4 hours

  3. Length of office visit

    A research associate will measure and record the start and stop time of the entire visit and the start and stop time of the surgeon consultation.

    Measured: Participants will be followed for the duration of the clinic visit, expected to last up to 4 hours

  4. Adherence to treatment recommendations

    We will measure adherence to treatment recommendations through a 6 week follow up questionnaire administered at least6 weeks after the date of patient's clinic visit or 6 weeks after the date of the patient's surgery, if they had surgery. The questionnaire will ask patients what treatment decision they decided on, to rate on a scale of 0-10 how often they participated in physical therapy if prescribed, rate on a scale of 0-10 how often they took medication if prescribed within the past 6 weeks.

    Measured: At least 6 Weeks

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 13 Dec 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Stage of decision making (time frame: Participants will be followed for the duration of the clinic visit, expected to last up to 4 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Dec 2012; AzTrials last refreshed its copy on 7 Nov 2026.
