Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The aim of this study is to contrast the use of standard burns dressings (mepitel, acticoat and hypafix- arm 1); with standard dressings AND negative pressure wound therapy (NPWT) (arm 2).

The specific NPWT we will use is the Renasys Touch. This will involve applying the standard dressings; which is what the control group will receive. In addition, the NPWT group will then have Kerlix and hypafix applied over the top. Film or an EasyDress bag will then be applied over this, a hole cut, a soft port applied, the negative pressure canister attached to the port and pressure then delivered.

Children will be randomised to an arm using RedCap, and then burns clinicians (either doctors or burns nurses) will apply the dressings as described. A series of photographs, laser doppler images and ultrasound images will be used to assess the progress of burn epithelialisation. Assessing clinicians will be blinded.

Mixed method questionnaires will be administered throughout the duration of the study to assess the ability to implement this practice - looking at feasibility, acceptability and appropriateness.

Adherence to treatment will be captured by clinic reviews and the feasibility questionnaire. Any patient who fails to attend their appointment will be called to ensure they are not lost to follow up.

Who will deliver the intervention: Burns doctors/Nurses with at least 3 years of clinical experience.
Mode of delivery: Face to face, provided individually
Number of times the intervention will be delivered: NPWT will be applied at the initial time of burn provided nil other treatment has been done; then, it will only be removed between days 5-7 (unless an adverse event occurs, in which case it will be removed, the information around the events logged and standard dressings used). NPWT will not be reapplied after the removal, and the patient will return to standard dressings.

Location where the intervention occurs: Queensland Children's Hospital
Intervention code [1] 320400 0
Treatment: Devices
Comparator / control treatment
Control group: current standard dressings for burns (mepitel, acticoat and hypafix)
- Current standard of care of burns patient at the Queensland Children's Hospital
- Provided by burns clinicians and nurses (at least 3 years experience)
- Always face to face, and application to the hand and feet
- Standard dressings are applied and then changed every 3-5 days, until the burn has completely re-epithelialised
Control group
Active

Outcomes
Primary outcome [1] 327343 0
Feasibility; this will be determined by a feasibility questionnaire distributed when the patients are recruited and at dressing changes. For staff involved with the dressings, a feasibility survey assessing the whole process will also be distributed at the start and end of the study.

This questionnaire was designed specifically for this trial, and based off a paper titled 'Psychometric assessment of three newly developed implementation outcome measures' which gives a framework for appropriate questions in qualitative research.
Timepoint [1] 327343 0
At commencement of the study, recruitment, removal of NPWT and completion of study
Primary outcome [2] 328489 0
Safety; any adverse outcomes will be recorded in a safety data base '

Adverse outcomes will be captured by both clinicians and participants in one of two ways - either at their clinic appointment or in the surveys they have to complete. The survey has been specifically designed for this study and will ask at the time the negative pressure wound therapy comes off if there were any adverse events

Adverse outcomes include: pain, itching, unable to achieve a seal with the negative pressure wound therapy
Timepoint [2] 328489 0
Duration of NPWT application
The outcome will be assessed at their next clinic appointment - which will be when we are removing the NPWT and approximately 4-7 days after initial application (as per protocol).
Secondary outcome [1] 394659 0
Time to re-epithelialisation - clinical photographs with burns clinicians then doing a blinded review of photographs to assess epithelialisation. The burn will be considered healed at 95% epithelialisation.
Timepoint [1] 394659 0
Re-epithelialisation - within acute period of burn treatment at all dressing changes
Secondary outcome [2] 399169 0
Pain

This will be assessed at home (between dressings via parents)

Parents
1. Participants self report of pain intensity using the Faces Pain Scale Revised (FPS-R) (if participant was aged 3 years or over);
2. Participant’s self report (if aged over 8 years) or the parents report of the participant’s pain intensity using a Visual Analogue Scale – Pain (VAS-P);
Timepoint [2] 399169 0
All dressing changes (parents will complete the survey to explain what they have observed at home in between dressing changes) and 3 months post commencement of intervention
Secondary outcome [3] 399170 0
Itch

Itch intensity will be self-reported for children aged 8 years and older using an 11-point NRS (0 to 10). The Toronto Pediatric Itch Scale is an observation based scale rating itch behaviours on a scale of 0 (absence of itch) to 4 (severe itch with significant disruption) and will be completed by caregivers for children aged under 5 years. Between the ages of 5 and 8, the Itch Man Scale will be used which asks patients to identify which picture on a 5 point scale (0 – 4) best represents their itch. Numeric rating scales have been recommended over visual analogue scales due to improved adherence, increased responsiveness and fewer missing values in populations of adults with pain and chronic itch.
Timepoint [3] 399170 0
All dressing changes and 3 months post-commencement of intervention
Secondary outcome [4] 399171 0
Scar - ultrasound scan to measure the thickness of the scar, three measurements will be recorded and then the median of these measurements used.
Timepoint [4] 399171 0
3 months post commencement of intervention
Secondary outcome [5] 399172 0
Range of motion - via OT review (where a combination of visual assessment and goniometer measurements will be used) and the Brisbane Burn Scar Impact profile
Timepoint [5] 399172 0
3 months post-commencement of intervention
Secondary outcome [6] 399173 0

As this is a feasibility pilot study, we predict 30 participants will be sufficient to determine safety and acceptability of the proposed intervention and outcome measures. Brickett and Day 1994 suggest that a pilot sample of approximately 10 are sufficient to perform a pilot study.

Summary
Brief summary
Paediatric Hand and Feet burns are a challenging injury for burns clinicians. They have a high prevalence and rate of ongoing morbidity. This is due to a combination of factors including children being curious about their environment and exploring with their hands, having slow withdrawal reflexes and hands and feet having multiple joints within a small body surface area. We believe the management of these burns could be further improved to try and reduce the ongoing morbidity. Currently, standard dressings (mepitel, acticoat and hypafix) are used to dress these burns but there is evidence to suggest that including Negative Pressure Wound Therapy as well may reduce the time to healing and therefore the ongoing morbidity. To include negative pressure as a standard practice of treatment, it must first be shown that it is both feasible and safe.

Hypothesis: That the use of NPWT is both feasible and safe in paediatric hand and feet burns.
