Improved Treatment for Patients With Long-term Opioid Therapy for Non-cancer Pain in Primary Care

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.
