Investigating the Role of Motivational Interviewing in Swedish Patients Undergoing Knee Arthroplasty

Knee arthroplasty is a successful surgical treatment for end-stage osteoarthritis. Most patients are satisfied with the result, however, 10% of the patients have remained dissatisfied over the last decades despite the advantages of the surgical procedure. Previous studies suggest that rehabilitation needs to be individualized and that some patients request additional support.

Patient empowerment is a patient-centered strategy to increase, amongst other, patient engagement, participation, and motivation. Patient empowerment can be defined as a "process that helps people gain control over their own lives and increases their capacity to act on issues that they themselves define as important". One way of increasing patient empowerment is through motivational interviewing. Motivational interviewing is an evidence-based approach in which patients are supported to identify behavior changes toward their own individual goals.

The aim of this study is to investigate if motivational interviewing could increase satisfaction in patients undergoing knee arthroplasty. Furthermore, we want to examine role MI in this patient group with interviews of both MI-practitioners and patients as well as detailed investigations about the MI sessions.

Motivational Interviewing

Behavioral

MI was introduced by William Miller in 1983 as a strategy to promote behavioral changes that would make people drink less. It is well established that MI can be successfully applied to many areas across the medical disciplines. Although the aim of MI is behavioral changes toward a specific goal it is necessary to understand the essence of MI with the "four key interrelated elements of the spirits of MI". These are partnership, acceptance, compassion, and evocation. Together they form an equal and respectful collaboration between the MI practitioner and the patient wherein empathy and acknowledgment are important pillars. Moreover, an important message derived from the spirit of MI is the belief that patients in themselves have and know what is needed and get support from the MI practitioner to find it.

Secondary outcomes

  1. Knee awareness

    Time frame: Preoperatively, 6 months postoperatively and 12 months postoperatively

    Assessed by the Forgotten Joint Score-12 (FJS)

  2. Self-reported pain and function

    Time frame: Preoperatively, 6 months postoperatively and 12 months postoperatively

    Assessed by the Knee Injury and Osteoarthritis Outcome Score (KOOS)

  3. Knee function

    Time frame: Preoperatively, 6 months postoperatively and 12 months postoperatively

    Assessed by the "5 times sit to stand"-test. Patients receive written instructions and perform the test themselves at home.

  4. Patient reported experience measures

    Time frame: 12 months postoperatively

    Three questions own patients own experiences

  5. Knee improvement

    Time frame: 6 months postoperatively, 12 months postoperatively

    Patient reported outcome. "Has your knee improved from the surgery?" Answer options: (1) Yes, the knee improved a lot from the surgery, (2) Yes, the knee improved a little bit from the surgery, (3) The surgery made no difference on the knee, (4) No, the knee is a little worse after surgery and (5) No, the knee is a lot worse after surgery

Other outcomes

  1. Depression

    Time frame: Preoperatively, 6 months postoperatively and 12 months postoperatively

    Assessed by the Patient Health Questionnaire-9 (PHQ-9)

  2. Health related quality of life

    Time frame: Preoperatively, 6 months postoperatively and 12 months postoperatively

    Assessed by the Short Form Health Survey (SF-36)

  5. Recordings of MI

    Time frame: 0 to 6 months postoperatively

    All 6 postoperative MI-calls on all patients in the intervention group is recorded and will be analysed by a group (MIQA-gruppen) that specialises in coding MI-calls.
