The goal of this clinical trial is to reduce inappropriate long term opioid treatment (LTOT) and to optimize pain management in patients with LTOT for chronic non-cancer pain in primary care through a new person-centred and team-based approach. The main question it aims to answer is: What are the effects of a new person-centred and team-based approach on pain interference in patients with LTOT for chronic non-cancer pain in primary care? Researchers will compare a new person-centred and team-based approach to usual care to see if pain interference is lower. Participants will receive a person-centred team-based treatment consisting of: * Phase 1 (investigation and assessment, week 1-3): A medication review, pain analysis and other assessments through separate visits to a pharmacist, general practitioner, physiotherapist, psychologist and care manager * Phase 2 (treatment plan, week 3-4): A team consultations with all healthcare personnel involved in Phase 1 including the patient where an individualized rehabilitation plan is made based. * Phase 3 (treatment and follow-up, week 4-24): Implementation of the individualized rehabilitation plan with frequent follow-up contacts (1 per 1-3 weeks) by phone with the care manager.
