Description of intervention(s) / exposure
Intervention: ALLEVYN Life dressing is a multi-layered design incorporating hydrocellular foam, hyper-absorber lock away core and masking layer. Indications for use: ALLEVYN
Alleyvn Life dressings will be placed on participant sacrum, both heels, and the occiput (if the occiput has been shaved for the purpose of clinical care) at the next scheduled repositioning after recruitment and randomisation.
To apply ALLEVYN Life follow the steps below:
1. Cleanse the skin in accordance with local clinical protocol.
2. Select an appropriate dressing size.
3. Prepare and clean the skin.
4. Using a clean technique remove one of the protector films from ALLEVYN Life and anchor the adhesive side of the dressing to the skin. Smooth the dressing over the skin ensuring there are no creases. When positioning ALLEVYN Life Sacrum dressings, place the narrow end of the dressing a minimum of 2cm (3/4in.) above the anal sphincter, then smooth the dressing over the sacrum.
5. Remove the remaining protector film and smooth the dressing over the remainder of the wound without stretching, ensuring no creases.

Heel and occiput dressings can be left in place undisturbed for up to 7 days. Sacrum dressings can be left in place for up to 5 days. All dressings will be changed more frequently if soiled.
To remove ALLEVYN Life, lift the edge of the dressing and slowly peel back until completely removed from the skin. ALLEVYN Life Sacrum should be removed from the top edge down towards the anus to minimise the potential for faecal contamination.

The dressings are indicated for single use only. Use of the dressings will continue for the participants stay in ICU and can be removed upon discharge from ICU, for example to a general ward.

The dressings will be placed by Alfred Health staff working in the ICU. This includes ICU nurses and research officers employed for this trial as they will have honorary Alfred Health status. The dressing is applied in addition to standard care. Dressing changes will be monitored using a data collection log maintained by the research officers employed for the trial and informed by changes sighted by the research officers as well as the dressing changes recorded on the ICU progress notes.

Prevention
Comparator / control treatment
No prophylactic dressing - usual pressure injury prevention strategies.
At the study setting standard practice includes a number of strategies to address the development of pressure injuries as informed by the Pan Pacific Clinical Practice for the Prevention and Management of Pressure Injury. The Institution has a Pressure injury Prevention Policy, a Pressure Injury Prevention and Management Guideline, and a Nutrition Intervention to Promote Pressure Injury Healing Guideline. The ICU has additional written technical instruction called ICU Pressure Injury Prevention Strategies. Standard care will be implemented in accordance with these guidelines. Standard care in these guidelines require skin and pressure injury risk assessment within 8 hours of admission, a documented pressure injury prevention plan within 24 hours of admission. Additional instruction is provided to guide the conduct of the skin and pressure injury risk assessment. Mandatory pressure injury prevention strategies implemented for all patients include initial and ongoing daily skin and pressure risk assessment, assessment and management of all bony prominences at risk of pressure damage, use of slide sheets when moving the patient, nutritional risk assessment. Patients are repositioned four hourly unless more frequent repositioning is indicated, low air loss mattress is used if spinal clearance received, heel wedges are used for off-loading, and skin care include the use of barrier creams and solutions and management of incontinence.

Outcomes
Primary outcome [1] 296413 0
Pressure injury incidence on the sacrum during ICU stay. Pressure injuries will be classified as per the NPUAP / EPUAP pressure injury classification system. Pressure injuries are classified according to four stages; Stage 1 PI involves non-blanchable erythema, Stage 2 PI involves partial thickness skin loss, Stage 3 PI involves full thickness skin loss, and at the most severe a Stage 4 PI involves full thickness skin loss which the bone, tendon or muscle is exposed. Research Officers will be responsible for assessing skin and determining the presence and stage of a pressure injury. Research Officers will be trained in assessing pressure injuries, inter-rater reliability will be determined. .

Efficacy
Statistical methods / analysis
Parametric and non-parametric measures will be used to compare the intervention and control groups at baseline to assess the effectiveness of randomisation to achieve comparable groups.
Analysis of the primary outcome measure will be conducted using a Cox’s Proportional Hazard model. An intention to treat analysis will be performed.
Repeated measures analysis of variance will assess differences in epidermal hydration, erythema and temperature for the two study groups, as well as the group of participants who developed a pressure injury and those that did not.
Path analyses of a mediation model will be conducted using AMOS structure equation modelling to further assess the role of microclimate in mediating pressure injury development for the two study groups.

To show a significant reduction of pressure injuries from 15.6% in the control to 3.1% in the intervention (an odds ratio of 5.78), a population prevalence of 10%, a power estimate of 0.80, and a significance level of 0.05, a total sample size of n=305 would be required. Allowing for a 10% attrition, a sample size of n=168 per arm (total n=336) will be sought.
