NCT01618097

Brief Summary

The purpose of this study is to advance the evidence base regarding methods for facilitating informed decisions among patients with knee and hip osteoarthritis by comparing DVD and online formats of decision aids for these conditions. The project will assess how these different formats impact key outcomes including: patient knowledge about treatment options, decisional conflict, preparation for decision making, decision self-efficacy, stage of decision making, and acceptability and usability of the decision aids.

Outcome Measures

Primary Outcomes (5)

  • Change in the Facts about Osteoarthritis section of the Decision Quality Instrument - Knee Osteoarthritis (DQI-KOA; © Massachusetts General Hospital, 2010 46) at Baseline to post.

    Knowledge is a key outcome in this study because it is fundamental to informed decision making process 45. We will use the "Facts about Osteoarthritis" section of the Decision Quality Instrument - Knee Osteoarthritis (DQI-KOA; © Massachusetts General Hospital, 2010 46), which includes 8 items that assess knowledge about the knee OA and its treatment options (behavioral, pharmacological, and surgical). Although this instrument was developed for knee OA, the items are also appropriate for hip OA, and it will be used for both groups.

    Baseline and 1 hour

  • Change in Decisional Conflict Scale at Baseline to post.

    We will use the Low Literacy version of this scale, which includes 10 items with 3 response categories (yes, no, unsure), across four subscales: Informed (do patients know the different options, benefits, and risks?), Values Clarity (are patients clear about which benefits and risk matter most to them?), Support (do patients have support and advice to make a choice?), and Uncertainty (are patients clear or sure about what to choose?).

    Baseline and 1 hour

  • Change in Decision Self-Efficacy Scale a Baseline to post.

    This is an 11-item scale that measures patients' confidence in completing various tasks related to the decision-making processes, such as getting facts about risks and benefits, asking questions, and expressing concerns. All items are measured on a scale of 0 (not confident at all) to 4 (very confident).

    Baseline and 1 hour

  • Change in the Facts about Osteoarthritis section of the Decision Quality Instrument - Knee Osteoarthritis (DQI-KOA; © Massachusetts General Hospital, 2010 46) at 30 days.

    Baseline and 30 days

  • Change in Decisional Conflict Scale at 30 days post.

    Baseline and 30 days

Secondary Outcomes (3)

  • Measurement of the Acceptability and Usability Scale post viewing of the DAs.

    Up to 1 hour

  • Semi-Structured Interviews

    Up to 1 hour

  • Time spent viewing different parts of the internet-based DA

    Up to 1 hour

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Clinician diagnosis of knee/hip OA, based on radiographic evidence in Duke medical records.
  • Moderate or worse current joint symptoms, assessed at telephone screening using standard items.

You may not qualify if:

  • Diagnosis of rheumatoid arthritis, fibromyalgia, or other systemic rheumatic disease.
  • Active diagnosis of psychosis or dementia, or other cognitive impairment.
  • Severe hearing or visual impairment that would prohibit effective use of the DAs.
  • Planning, scheduled for or on a wait list for joint replacement surgery.
  • Had a prior hip or knee joint replacement surgery.
  • Inability to read English, since the DAs are in English.
  • Current participation in another OA interventional study.
