Hand Osteoarthritis

Brief summary

The main aim of this project is to assess the effect, cost-effectiveness and user experiences with using an e-self-management intervention in addition to treatment as usual compared to treatment as usual alone in patients with hand osteoarthritis. The study is an RCT comprising approx 400 participants with hand osteoarthritis recruited from primary and secondary healthcare in all four health regions in Norway.

Detailed description

Hand osteoarthritis (OA) is a highly prevalent rheumatic joint disease, and the number of people living with debilitating hand OA will continue to rise in the coming decades due to increased life expectancy. Research shows that patients with hand OA have poor access to recommended treatment, and in Norway, they are increasingly referred to surgical consultation before having received recommended first-line treatment. Thus, there is a need to develop easily viable models of care for patients with hand OA that make recommended treatment available across different healthcare levels. Our hypotheses are that an e-self-management intervention for people with hand OA will improve pain and function and be more cost-effective compared to treatment as usual, and that this app can easily be implemented in both specialist and primary healthcare. The hypotheses will be tested and explored in a randomized controlled trial, with a qualitative study nested within this trial. The main research questions are: 1. To evaluate whether a 12-week e-self-management intervention is more effective in improving pain and function (according to the OMERACT-OARSI responder criteria26) compared to usual care in patients with hand OA (randomized controlled trial). 2. To determine the cost-effectiveness of the e-self-management intervention compared to usual care after 6 months (randomized controlled trial). 3. To explore patients' experience of barriers and facilitators for adopted and continued use of a e-self-management intervention for treatment of hand OA (qualitative interviews). Secondary research questions will also be assessed. Approx 400 patients will be recruited in this multicenter randomized controlled trial where patients with hand OA are allocated to either usual care or a 12-week e-self-management intervention delivered through a smartphone app (the HAPPY Hands app). Outcome measures are collected at baseline, 3 months (=end of intervention) and 6 months

Interventions

OTHERe-self-management intervention (Happy Hands app)

The 12-week intervention consists of 30 short informational videos addressing the themes prioritized by the patient research partners. These themes are further operationalized into the following categories: Information on hand OA, Hand exercises, Use of assistive devices and orthoses, Medication and surgical alternatives, and Self-management of the disease. Additionally, the intervention includes a hand exercise program consisting of 8 videos providing instructions on warm up, exercises to improve mobility, strength and coordination, and a stretching exercise. The intervention group will additionally receive treatment as usual.

OTHERTreatment as usual

Treatment as usual may vary from no treatment at all to referral to a patient education group program, or occupational therapy.

Design outcomes

Primary

MeasureTime frameDescription
OMERACT/OARSI responder criteriaBaseline and 3 months follow-upCombined score of change in pain, function and disease activity. Patients are categorized into responders or non-responders according to the following: High improvement on pain or function: 1. ≥50% improvement + absolute change of ≥2 in pain (numeric rating scale, NRS 0-10), OR 2. ≥50% improvement + absolute change of ≥0.6 in function (Measure of Activity Performance of the Hand, MAP-Hand) Improvement in at least two of the three following: 1. ≥20% improvement + absolute change of ≥1 in pain (NRS) 2. ≥20% improvement + absolute change of ≥0.3 in function (MAP-Hand) 3. ≥20% improvement + absolute change of ≥1 in global assessment of disease activity (NRS)
