Study type
Description of intervention(s) / exposure
Hypnosis Recording: The recording is approximately 25 minutes long and is based on a technique called Rapid Induction Analgesia (RIA), first proposed by Barber (1977). The script uses several hypnotic techniques to create a state of deep relaxation and receptivity, making the patient open to suggestions about their pain experience. Participants will listen to the recording 5 times and then they will listen to it again during their next dressing change. Patients will have 2-4 days to listen to the recordings and will listen to them once or twice each day, according to their choice and the time they have available. The procedure will take between 30 and 90 minutes depending on the nature of the burn injury. A nurse will assist participants to schedule listening to the recording.

Treatment: Other
Comparator / control treatment
The study will use one control condition. this will be a "treatment as usual" condition where the participant will receive usual care during dressing changes.

Measurements will also be taken during one dressing change prior to any intervention/control condition, to act as a baseline measure for all participants.

Brief summary
Burn injuries and treatment often cause excruciating pain for patients. Hypnosis has demonstrated benefits in treating pain in addition to pharmacological pain management. However, psychological pain management techniques are not currently used in standard pain management protocols on burns units.

Audio recordings could be an efficient way for patients to access these treatments, and nurses may be well-positioned to assist patients to use them, as they spend more time with the patient than other clinicians and are usually present during wound dressing changes.

The aims of this project are:

1. To explore the feasibility of using audio recordings of hypnosis as an adjunct to pharmacological treatment of burn pain.
2. To explore the feasibility of nurses assisting with the administration of hypnosis recordings.

Adults over 18 years of age who are admitted to the burns unit with an injury that requires surgery will be screened and those who are eligible will be invited to participate in the study.

Pain, anxiety and relaxation will be measured for all participants during a dressing change to give baseline information. Then patients in an experimental group will be asked to listen to a 25 minute recording of hypnosis 5 times to practice before using the recording in a further dressing change. Those in a control group will receive standard care during their dressing changes. After dressing changes patients will be asked to rate their pain, anxiety and relaxation experience. Nurses will administer the recordings.

The experiment will follow a repeated-measures between groups design, which means that pain, anxiety and relaxation ratings and personality measures can be compared between the groups before and after treatment.

Results will provide information about the benefits of hypnosis and mindfulness audio recordings for patients on the burns unit, and the feasibility of using nurses to administer these. They will also provide valuable information about personality variables that influence how well someone will benefit from either treatment, which will assist with treatment planning.
