Brief Summary
The study investigates long-term opioid treatment in patients with chronic non-cancer pain (CNCP). The study aims to prospectively identify predictive factors for work ability and for developing opioid use disorder (according to DSM-5) as well as predictive factors for pain, activity, and health-related quality of life. It is hypothesized that certain biopsychosocial factors mapped in this study predict patterns of opioid use and the risk for developing OUD for patients with CNCP on long-term opioid therapy. Further, it is hypothesized that certain biopsychosocial factors mapped in this study predict the chance of improved work ability and other treatment benefits of long term opioid therapy in patients with CNCP.

Outcome Measures
Primary Outcomes (2)
Characterization and changes in opioid use disorder
As defined in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Measured by: Structured interview: Modified version of the Swedish Mini International Neuropsychiatric Interview, Part J (Substance use). Response format yes/no. Mild opioid use disorder = 2-3 symptoms Moderate opioid use disorder = 4-5 symptoms Severe opioid use disorder = 6 or more symptoms
Baseline, 1 year, 2 years, 3 years, 4 years, 5 years
Changes in work ability
Self report. Work Ability Index (WAI). The questionnaire covers 7 dimensions: 1. current work ability compared with lifetime best 2. work ability in relation to the demands of the job 3. number of diagnosed illnesses or limiting conditions 4. estimated impairment owing to diseases/illnesses or limiting conditions 5. amount of sick leave during the last year 6. prognosis of work ability in 2 years' time 7. psychological resources. The dimensions have different scores. A total index is computed ranging from 7 to 49, where higher scores indicate higher work ability. Individual items or sub-scales of WAI may also be used as outcome measures.
Baseline, 1 year, 2 years, 3 years, 4 years, 5 years
Secondary Outcomes (26)
Changes and patterns of opioid use (type of opioid, dose, and duration)
Baseline, 1 year, 2 years, 3 years, 4 years, 5 years
Changes in pain severity and pain interference: The Brief Pain Inventory short-form (BPI-SF)
Baseline, 1 year, 2 years, 3 years, 4 years, 5 years
Changes in health related quality of life: EQ-5D-5L
Baseline, 1 year, 2 years, 3 years, 4 years, 5 years
