The primary aim of the trial is to assess if an information- and self-management app provided in the period between referral and consultation in specialist healthcare can improve knowledge about osteoarthritis and decision quality during consultation in patients with knee osteoarthritis. 204 patients will be randomized to either being on the waiting list for consultation, accessing publically available information about osteoarthritis (control group) or getting access to an 8-week information- and self-management intervention delivered through the Genus app prior to consultation. Pasients with answer questionnaires at baseline, 4 weeks (intervention group only), 8 weeks, post consultation and 1 and 2 years after consultation. The Genus app contains information videos, exercise videos, quizzes, feedback and questionnaires provided in a progressive order over an 8 week period.

RECRUITINGKnee Osteoathritis Knowlegde Scale (KOAKS)
11 statements about osteoarthritis and treatment options, answered on a 5-point scale from 1 (=true) to 5 (=not true), summed up to a scale from 11 to 55
Time frame: Baseline, 8 weeks, approx. 2-4 months after baseline (1 day after consultation (post consultation))
Decision Conflict Scale (DCS)
16 statements with 5 response categories about the patients uncertainty with treatment options. The total score range from 0 (no decisional conflict) to 100 (extreme decisional conflict). The DCS also has five subscales (all 0-100): 1) uncertainty, 2) informed, 3) values clarity, 4) support, and 5) effective decision.
Time frame: approx. 2-4 months after baseline (1 day after consultation (post consultation))
Concordance between preferences and treatment decision
Measured with one qustion form the Decision Conflict Scale (DSC), 5 response options.
Time frame: approx. 2-4 months after baseline (1 day after consultation (post consultation))
Decisional quality
Measured with section 3 (decision process scale) in the Decision Quality Index for Knee Osteoarthritis (K-DQI) which consists of 5 questions. Four of these questions are summed to a 0-4 score with higher score indicating more shared decision-making.
Time frame: approx. 2-4 months after baseline (1 day after consultation (post consultation))
Level of shared decision-making
Mesured with the CollaboRATE questionnaire, comprising 3 questions measured on a 0-9 scale, with a higher score indicating better experience. Scores are calculated using the top score method indicating the percentage of patients scoring top score for all three questions, or
Time frame: approx. 2-4 months after baseline (1 day after consultation (post consultation))
Satisfaction with treatment choice
Measured on a numeric rating scale (0-10, with higher score indicating more satisfaction)
Time frame: approx. 2-4 months after baseline (1 day after consultation (post consultation))
