Study Description

Brief Summary

This study is a 2X2 factorial randomized trial that will the examine the comparative effectiveness of two patient decision aids for hip and knee osteoarthritis (OA) as well as the impact of a surgeon-focused intervention.

Detailed Description

This study is a 2X2 factorial randomized trial that will examine the comparative effectiveness of different decision support strategies for patients making treatment decisions about hip or knee osteoarthritis (OA). Eligible patient subjects will be randomly assigned to receive one of two decision aids before their upcoming clinic visit with a participating orthopedic specialist. Participating providers are randomly assigned to either usual care or an intervention (a report that includes patients' goals and treatment preferences). Patient participants will complete three surveys at different time points: before their orthopedic visit, one week after the clinic visit, and 12 months later. Providers will complete a short survey for a subset of patient participants. The study is titled the DECIDE-OA study.

Outcome Measures

Primary Outcome Measures

  1. Patients Knowledge [before orthopedic visit]

    Knowledge sub-score generated from responses to the Hip or Knee Decision Quality Instrument (DQI). Scores range from 0-100%, with higher score meaning higher knowledge.

  2. Percentage of Patients Who Received Preferred Treatment [1 week after visit with orthopedic surgeon]

    Patient preferred treatment item from the Hip or Knee Decision Quality Instrument will be compared with the treatment received to determine percentage of patients who received treatment that matched their preferences.

Secondary Outcome Measures

  1. Percentage of Participants Who Used the Decision Aid [before orthopedic visit]

    1 item asking patients how much they reviewed the program (none, some, most, all). The percentage who report viewing most or all will be calculated.

  2. Change in Quality of Life [before orthopedic visit; 12 months from date of orthopedic visit]

    Overall quality of life (EQ-5D) scores will be calculated and the impact of decision support strategies on change in quality of life will be examined. Scale ranges from -0.11 to 1.00, with higher (positive) values meaning better overall health. The minimum important change is 0.10 points.

  3. Surgical Rates [6 months after the initial visit]

    Medical chart review and patient report of whether or not surgery was used in the 6 months after the visit.

Study Results

Participant Flow

Recruitment Details April 2016-December 2017. Adults diagnosed with hip or knee osteoarthritis who had a visit scheduled with a participating orthopedic surgeon at 3 sites were invited to participate before their visit.
Pre-assignment Detail Participants were randomized to a study arm after screening the surgeons' schedules. To be eligible for the study, patients needed to attend the visit with the surgeon. The majority of post randomization exclusions are due to patients not showing up to the visit. Some are due to limited clinical information available at screening.
