Plain English Summary
Background and study aims
Pressure garments are tightly fitting pieces of Lycra-based clothing which apply a constant pressure directly on the skin. They are used for patients who have had burn injuries and are worn day and night for about 12 months after the actual burn wound has healed. Wearing these garments may reduce the potential complications of scarring while providing comfort and helping to improve symptoms such as itch, which can be very distressing for patients recovering from burns. However, there is little evidence to confirm this and there is a lack of information about the costs of the garments and the staff time required to provide this treatment. There are also costs to patients, parents and carers which can include discomfort and possible damage to the skin, and the inconvenience of having to attend frequent outpatient clinic appointments to have the garments fitted. It can be challenging to keep going with the pressure therapy and some patients find it too difficult to stay the course. In order to run a large study of the clinical and cost effectiveness of pressure garment therapy, we first need to have more information about the patients and healthcare professionals who might participate, and identify possible barriers and measurement problems.
Who can participate?
Adults and children with burn injuries
What does the study involve?
First, we investigate the current practice of using pressure garments. We carry out a survey to find out numbers of patients using pressure garments and what other scar management strategies are being used. Secondly we gather background information including the views and perspectives of staff in specialist burns units in the UK. We are particularly interested in their willingness to recruit participants and their views on important outcomes for patients. Thirdly, we are keen to understand patient or carer views on a study where patients would be randomly allocated to use or not use pressure garments, and to identify outcomes that are important to them, both in the short and long term. We then design a pilot study to compare patients using or not using pressure garments. The patients invited to take part are those who, in current circumstances, would be offered pressure garments. This helps us to assess how willing healthcare professionals are to ask their patients to participate in such a study, and the willingness of patients to be recruited and to carry out the treatment as prescribed. Both recruitment and adherence to treatment are vital to produce results that are reliable and valid. Assessments of costs and benefits are also undertaken during this phase. The pilot study should provide a good indication of any changes that are needed if a larger study is to be undertaken in the future. In order to identify any issues that could interfere with running a full study, we carry out an evaluation of the process of setting up and participating in this pilot study. This involves interviews with healthcare professionals, participants and non-participants to provide us with insights into any difficulties encountered. Patients are reviewed over the course of 12 months. It is already known that compliance with pressure garment treatment can be variable, and during this phase of the study both patient diaries and questionnaires are used to help identify the most accurate method of measuring treatment adherence.

Study information
Scientific title
A feasibility study and open pilot two-arm randomised controlled trial comparing Pressure Garment Therapy with no Pressure Garment Therapy for the prevention of abnormal scarring after burn injury (PEGASUS)
Acronym
The PEGASUS Trial - Comparing PGT with no-PGT
Study hypothesis
Recovery from a burn injury is a long process, involving a number of physical and psychological challenges for patients. Scarring and the appearance of scars are important concerns for patients. Pressure garment therapy (PGT) has become the treatment of choice to control abnormal scarring of the damaged skin and has been used routinely since the 1970s. However, its effectiveness has been difficult to measure. The overall aim of the proposed study is to find out how likely it is that we can design and conduct a large clinical trial to assess whether patients treated with PGT to have better outcomes, such as reduced scarring, or reduce the time to maturation compared to burns patients that do not use PGT.
The study will be carried out in two phases P1 and P2.
In Phase 1: Firstly, we will investigate current practice of using PGT. We will carry out a survey to establish the number of patients receiving pressure garment therapy, what protocols for scar management are being used, and what other scar management strategies are employed. Secondly, we will explore views and perspectives regarding an RCT of pressure garment therapy from staff in specialist burns units in the UK. Thirdly, we will explore patient (adults and children) and carer views on a trial where patients would be randomised to pressure garment therapy or no pressure garment therapy and to identify outcomes that are important to them, both in the short and long term.
In Phase 2: A pilot trial informed by Phase 1 will compare pressure garment therapy versus no pressure garment therapy in adults and children recovering from burn injuries. A qualitative process evaluation will run alongside this trial.
