Plain English Summary
Background and study aims
Nearly eight million people (15%) in England suffer from moderate to severe long-term (chronic) pain. Chronic pain can severely impact on overall health and functioning, and can greatly reduce quality of life. Treatment with opioids (strong pain relief medication) is often recommended, however the side effects of taking these medications can often outweigh the benefits of long term use. Previous work has found that self-management and cognitive behavioural therapy (a type of talking therapy that changes the way people think and behave) can support pain management. In this study, these techniques have been adapted and developed a self-management course to help people cut down on opioid use. The aim of this study is to test the effectiveness and cost effectiveness of this new self-management program in helping people to reduce their opioid consumption and improve quality of life.
Who can participate?
Adults who are taking opioid medication for long-term pain (not cancer related).
What does the study involve?
Participants are randomly allocated to one of two groups. Those in the first group continue to receive usual care from their GP and are sent a manual containing advice about how to manage long-term pain and information about the side effects of taking opioids to use as a learning tool. They also receive a relaxation CD so that they can practice relaxation techniques. Participants receive the same as those in the first group but are also invited to take part in a short three-day course. During the course, participants take in groups with others who use opioids to manage chronic pain and think about their own lifestyle, experiences and behaviours. The course also involves education about a range of topics, including understanding pain, coping techniques, relaxation techniques, prescribing opioids for chronic pain, short and long term effects of opioids, pain control after opioids and managing reduction of opioids. All participants are asked to complete a weekly diary for the first four months of the study. They then complete follow up questionnaires at four, eight and twelve months about their pain levels, opioid use and activities of daily living (what they can do).
What are the possible benefits and risks of participating?
Participants may benefit from learning to better manage their pain and to reduce their use of opioids. There are no major risks involved with taking part however some participants may experience withdrawal symptoms from lowering their opioid dose.

Improving the Wellbeing of people with Opioid Treated Chronic pain: I-WOTCH
The aim of this study is to test the effectiveness and cost effectiveness of a multicomponent self-management intervention targeting withdrawal of strong opioids on activities of daily living for people living with chronic non-malignant pain.

Participants are randomised to one of two groups.
Self-learning manual group: Participants will be sent a manual with advice about chronic pain management and the potential implications and adverse effects of using opioids. It is a learning tool. These participants will also receive a relaxation CD and instructions on how to use it. Participants will be asked to practice and use the relaxation techniques in their own time. Participants will continue to receive their usual GP care whilst taking part in the I-WOTCH study.
Support programme group: Participants will be invited to a short course in addition to the above. The course is led by two facilitators and runs over 3 days. During the course participants will be encouraged to talk in a group with others who use opioids to manage chronic pain and think about their own lifestyle, experiences and behaviours. There will be an average of 12 people in a group. The course will include sessions about understanding pain, coping techniques, relaxation techniques, prescribing opioids for chronic pain, short and long term effects of opioids, pain control after opioids, managing reduction of opioids and more.
Participants will attend the first and second group days and then meet on a separate day with the I-WOTCH nurse for a one to one consultation. At this consultation the nurse and participant will create an opioid tapering plan. The third group day will follow the consultation. These activities happen over approximately 4 weeks.
From weeks 5-10 the participant has two telephone consultations with the nurse and then a further face to face consultation with the nurse to see how they are getting on with their tapering plan.
All participants will be asked to complete a weekly diary up until 4 months from their randomisation into the study. At 4, 8 and 12 months all participants will be asked to complete a follow up questionnaire.
Primary outcome measure
Activities of daily living are measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference Short Form (8A)(PROMIS-PI-SF-8A) at baseline, 4, 8 and 12 months.
Secondary outcome measures
1. Self-reported data on opioid use will be collected using a postal questionnaire at baseline, 4, 8 and 12 months
2. Pain severity is measured using the PROMIS Scale V1.0 – Pain Intensity Short Form 3a at baseline, 4, 8 and 12 months
3. Symptoms are measured using the Severity of Opioid Withdrawal (Symptoms): Short Opiate Withdrawal Scale (ShOWS) at baseline, 4, 8, 12 months and weekly from randomisation to 4 months
4. Health related quality of life is measured using the SF12 V2.0 and EQ5D-5L at baseline, 4, 8 and 12 months
5. Sleep quality is measured using the Pittsburgh Sleep Quality Index at baseline, 4, 8 and 12 months
6. Emotional wellbeing is measured using the Hospital Anxiety and Depression Scale (HADS) at baseline, 4, 8 and 12 months
7. Self-efficacy is measured using the Pain Self Efficacy Questionnaire (PSEQ) at baseline, 4, 8 and 12 months
8. Resource use is measured using a combination of routinely collected NHS data, GP data, HES data and patient self-reported data at 4, 8 and 12 months
