Improving the Wellbeing of Opioid Treated Chronic Pain (I-WOTCH): Results of a UK Randomised Controlled Trial

The I-WOTCH study (a pragmatic multi-centre randomised controlled trial, N=608), set out to test the effectiveness and cost effectiveness of a multicomponent intervention to reduce opioid use. Participants were people living with chronic non-malignant pain. We targeted withdrawal of strong opioids. Two primary outcomes at 12 month follow up are Patient-Reported Outcomes Measurement Information System Pain Interference Short Form (8A)) and opioid use. Secondary outcomes include quality of life (measured by the EQ-5D). In depth process evaluation and qualitative interviews were completed. The main trial analyses are complete and being written up for publication. This will be the first presentation of these important findings.
