Improving the Wellbeing of People with Opioid Treated Chronic Pain (I-WOTCH)

Chief Investigator: Dr Harbinder Sandhu

Sponsor: University of Warwick

Funder: National Institute for Health Research, Health Technology Assessment 14/224/04

Registration Number: ISRCTN 49470934


The I-WOTCH study is developing a support programme that aims to improve the everyday functioning for people living with chronic (long-term) pain and reduce their opioid (strong morphine-like painkillers) use.

The I-WOTCH study is a randomised controlled trial which is comparing two different treatments for people with long-term pain. The two treatments are:

GROUP 1 Usual GP care plus a opioid information booklet and relaxation CD

GROUP 2 A support programme in addition to the above.

Please see 'Information for the public' for more detailed information.

The purpose is to find out which treatment is best at helping people to live better with their pain and reduce their use of opioids. This trial will help us identify which treatment is more effective. It will measure the everyday functioning and opioid use of all the people in the trial at different time points. We hope that the results of this study will be used to help patients with chronic long-term pain in the future.

Sample Size:

542 participants

Primary Outcomes:

1) Activities of daily living measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference Short Form (8A)(PROMIS-PI-SF-8A).

2) Opioid use
