Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There are two arms to this research. The first arm will study Stratamed on facial burn wounds and the second arm will study StrataXRT on donor site wounds. Stratamed and StrataXRT are different products but are both silicone based wound care products.

Research Arm 1: Stratamed - a topical silicone film forming dressing that will be used in non-surgical face burn wounds.
1) A thin layer of topical silicone gel will be smeared over the entire facial burn wounds for those patients randomised to the intervention group. For those randomised to the control group they will follow the same dressing protocol using standard care with emollient.
2) In between dressing appointments and when at home, patients will be required to wash their face wounds three times daily and reapply another thin layer of topical silicone or emollient every 2 hours.
3) Patients will need to attend dressing clinics for wound reviews within the following schedule. Day 2-5, day 5-7, day 7-10 and day 10-14. Clinics are not open on public holidays and on weekends so follow up appointments need to be made within the ranges of days as above.
4) When attending dressing appointments a nurse will assist the patient with washing their face wounds. The researcher will take pain outcome measures and arrange clinical photography of the face burn wounds. A blinded clinical nurse will assess the percentage of wound healing. If still requiring treatment, another layer of topical silicone gel or emollient will be reapplied as per the allocation group.
7) The blinded clinical nurse will assess if the face wounds are fully healed. Once healed, topical silicone or emollient will be ceased, and standard care for healed face burns will be taught by the Occupational Therapist.
8) The participants will attend clinic appointments at 6 weeks and 3 months post burn injury for routine scar assessments. At these same appointments outcome measures for scarring will be completed including clinical photography, patient POSAS questionnaire, dermalab measures (pigment and vascularity) and Vancouver Scar Scale (VSS) assessment.

Research Arm 2: StrataXRT - a topical silicone film forming dressing that will be used on donor sites. In participants with two donor sites, the intervention will be randomised to the medial or lateral donor site. In participants with only one donor site will be included. These donor sites will be halved laterally and the treatment will be randomised to one side of the donor site.

1) Randomisation will occur at the point of surgery in theatre. The intervention donor site will receive a thin layer of topical silicone gel (StrataXRT) to the dressing. The StrataXRT gel will be smeared over the dressing before being applied to the intervention donor site wound. The control donor site will have the same dressing but it will not have a layer of gel applied to it.
2) The same type of dressings will be used at each dressing change until the donor site wounds are healed. This will be an Algisite and fixomull dressing and will be applied at baseline in theatre. Both both donor sites will receive the same dressing but only the intervention donor site will have the topical silicone smeared over its dressing.
3) The patients will need to attend dressing clinics for dressing changes within the following schedule. Day 2-5, day 5-7, day 7-10 and day 10-14. Attendance can only occur during week days as dressing clinics are not open weekends and public holidays. The donor site dressing will need to remain intact for 5 days, however, this can be changed earlier if the dressing has significantly leaked or if day 5 falls over a weekend or public holiday. Therefore the day of the week the donor site dressing will next be changed is determined by the day of surgery (when the donor site wound is created).
4) Donor site wounds will be changed by a nurse with the patient alert and lying down in the clinic room. The researcher will collect pain outcomes before donor site dressings are removed. The donor site wound will be the first dressing to be changed and any other burn wound or graft dressings will remain intact at this point.
5) Once the burn donor site dressing is removed and cleaned, photographs will be completed by clinical photography and the separate blinded clinical nurse wound assessor will assess the percentage of wound healing in both the intervention and control donor sites. The donor site wounds can then be re-dressed with a clean Algisite and fixomull dressing with StrataXRT applied to the dressing for the intervention donor site. The primary research investigator will liaise with and observe nursing staff to ensure that participants remain in the same allocated control or intervention group and the same dressing protocol and application is adhered to. The patient will be blinded to this process and will not be able to see the preparation of the donor site dressings and application of StrataXRT. The patient will then be asked to complete outcome measures including the pain intensity scale, and a pain questionnaire. Any other burns wounds or dressings can then be changed.
6) The patient will continue to attend appointments for donor site dressing changes and outcome measures until the blinded nurse assessor confirms the donor site wounds are healed. Once healed, StrataXRT will cease and the patients will no longer require dressings. Standard care of moisturising for healed donor sites will proceed.
7) At 6 weeks and 3 months post burn injury outcome measures for scarring will be completed at follow up clinic appointments. Scar outcome measures will be completed by blinded Occupational Therapists and include dermalab measures (pigment and vascularity) and VSS. The researcher will facilitate clinical photography, and the on-line patient POSAS will be completed by the patient.
Intervention code [1] 301633 0
Treatment: Drugs
Comparator / control treatment
First arm - burn wounds not requiring surgery (faces), will receive standard care which is topical emolient.
Second arm - donor sites, will receive standard care which is an algisite and fixomull dressing.
The timing of appointments for dressing changes for faces and donor sites, and the 6 week and 3 months scar review appointments are all standard care for all burns patients.
Control group
Active

Outcomes
Primary outcome [1] 306442 0
Time to healing will be assessed by a blinded clinical nurse. Clinical photography using an angled ruler of face and donor site wounds will be completed at each dressing change. The blinded nurse will then measure the percentage healed and record this following each dressing change appointment. The wound will be considered healing once wounds are fully epithelialised and the nurse determines that no further dressings are required.
Timepoint [1] 306442 0
Baseline will be first presentation to dressing clinic for face burns in arm 1, and in study arm 2 baseline will be the point of surgery. Dressing changes and outcome measures will be completed subsequently at, days 2-5, days 5-7, days 7-10 and days 10-14 after intervention commencement. The same nurse will complete wound assessments and determine percentage of wound healing through clinical photography with an angled ruler following each dressing appointment which could fall within the above ranges.
Primary outcome [2] 306443 0
At each clinic appointment, pain outcome measures will be taken both prior to, and at the conclusion of dressing changes for face burns and donor sites. The researcher will ask the participant to complete a Pain Intensity Scale and a short questionnaire that has been specifically designed for this study. This consists of 4 questions. Do you donor sites hurt? Is site A worse than B? Is site A better than B? Does it all feel the same?.
Timepoint [2] 306443 0
For the first arm with face burns, baseline will be first presentation to dressing clinic. In the second arm for donor sites, baseline will be the point of surgery.
Outcome measures will be completed at subsequent dressing changes with time point 1 from day 2 to 5 (depending on which day of the week they are returning to clinic), time point 2 from day 5 to 7, time point 3 from day 7 to 10 and time point 4 from day 10 to 14 after intervention commencement. The same pain intensity scale and questionnaire will be completed at the same timepoints i.e. at each dressing change appointment. The end point will be the date recorded as the day the wound is healed.
Secondary outcome [1] 348562 0
This is a composite secondary outcome specifically assessing scarring outcomes at 6 weeks and 3 months for both faces and donor sites.
Several outcomes measures will be completed in the same appointment and to the same testing sites.
1) The patient POSAS questionnaire will be completed by the patient, and a blinded OT will complete dermalab measures and the VSS.
2) Testing sites for the Dermalab and VSS will be identified for both the intervention and control groups for both arms of the study.
Faces: Testing sites include first 1) point healed, 2) last point healed and 3) contralateral unaffected skin.
Donors: Where small single donor sites are used - testing sites will be the proximal lateral corners of both intervention and control donor sites. Where two donor sites are used - testing sites will be the most central point.
3) A blinded research assistant or OT will take dermalab recordings and VSS measures in the same clinic appointments. The dermalab uses probes to measure the characteristics of scarring. This study will only use the Dermalab to measure vascularity and pigmentation. The recording provides a numbered reading. The VSS is a scale completed by a blinded OT to measure pigmentation, vascularity, pliability and height.
Timepoint [1] 348562 0

Type of endpoint/s
Statistical methods / analysis
Statistics:
Descriptive, univariate statistics will be used to describe the general characteristics of the sample. Control and intervention areas will be examined using the Wilcoxon Signed Rank test and a p value < 0.05 will be considered to indicate statistical significance. The statistical package (SPSS) program will be used.

Sample Size:
We are proposing a sample size of 90 patients (First Arm - 30 intervention and 30 control, Second Arm - 30 donor sites). To detect a standardised difference of 1.58 between the two groups with 80% power and a significance set at 0.05 then 90 subjects are needed in total.
