Silicone Adhesive Multilayer Foam Dressings to Prevent Pressure Ulcer

Not Applicable

Completed

Conditions: Pressure Ulcer

Interventions: Device: Allevyn® brand silicone adhesive multilayer foam dressings
Device: Mepilex® brand silicone adhesive multilayer foam dressings

Registration Number: NCT03442777

Lead Sponsor: Belgium Health Care Knowledge Centre

Brief Summary: The objective of this study is to determine if silicone adhesive multilayer foam dressings applied to the sacrum, heels and greater trochanter in addition to standard prevention reduce pressure ulcer incidence category II, III, IV, Unstageable and Deep Tissue Injury (DTI) compared to standard pressure ulcer prevention alone, in at risk hospitalised patients. In particular, this trial extends previous trial results obtained in ICU setting. Therefore, only a maximum of 25% of patients will be recruited from ICU settings.

The hypothesis is: 'The use of silicone adhesive multilayer foam dressings as adjuvant prophylactic therapy for pressure ulcer prevention is more effective in reducing pressure ulcer category II, III, IV, Unstageable, and Deep Tissue Injury (DTI) incidence rate on sacrum, heels and greater trochanter, compared to standard pressure ulcer prevention alone.' The null hypothesis is: 'The use of silicone adhesive multilayer foam dressings as adjuvant prophylactic therapy for pressure ulcer prevention is not more effective in reducing pressure ulcer category II, III, IV, Unstageable, and Deep Tissue Injury (DTI) incidence rate on sacrum, heels and greater trochanter, compared to standard pressure ulcer prevention alone.

Detailed Description: A multicentre randomised controlled open label parallel group medical device trial in approximately 8 hospitals in Belgium.

Patients will be randomly allocated to three study arms based on a 1:1:1 allocation:

Study arm 1 (on top of standard of care):

* Patients at risk for pressure ulcer category II, III, IV, Unstageable, and Deep Tissue Injury (DTI) development will receive standard pressure ulcer prevention strategies (as described in the hospital protocol) which include ongoing risk assessment, regular repositioning and skin care.

* Skin sites (restricted to sacrum, heel right/left and greater trochanter right/left) will be treated with silicone adhesive multilayer foam dressings by Smith \& Nephew (Allevyn® brand).

Study arm 2 (on top of standard of care):

* Patients at risk for pressure ulcer category II, III, IV, Unstageable, and Deep Tissue Injury (DTI) development will receive standard pressure ulcer prevention strategies (as described in the hospital protocol) which include ongoing risk assessment, regular repositioning and skin care.

* Skin sites (restricted to sacrum, heel right/left and greater trochanter right/left) will be treated with silicone adhesive multilayer foam dressings by Mölnlycke Health care (Mepilex® brand).

Study arm 3 (standard of care):

* Patients at risk for pressure ulcer category II, III, IV, Unstageable, and Deep Tissue Injury (DTI) development will receive standard pressure ulcer prevention strategies (as described in the hospital protocol) which include ongoing risk assessment, regular repositioning and skin care.

* No silicone adhesive multilayer foam dressings will be applied on the skin sites of interest for this trial (sacrum, heel right/left, greater trochanter right/left).

Skin sites (restricted to sacrum, heel right/left, greater trochanter right/left) of patients at risk for pressure ulcer category II, III, IV, Unstageable, and Deep Tissue Injury (DTI) development will be assessed daily for a maximum period of 14 days.

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 1634

Inclusion Criteria

At risk for pressure ulcer development based on Braden risk assessment (Braden score ≤17).
Admitted to hospital within the previous 48 hours. Note: Not more than 25% of patients per site should be recruited at ICU wards.
Skin at sacrum is assessable and there is no clinically relevant incontinence- associated dermatitis (IAD*) or another skin condition that would be a contra-indication for the application of the devices under study, and there is no pressure ulcer category II or worse present.

*clinically relevant IAD is defined as any of the 4 categories described in the publication http://users.ugent.be/~dibeeckm/globiadnl/nlv1.0.pdf
For at least 3 of the following 4 skin sites (heel left, heel right, greater trochanter left, greater trochanter right) one of the following two conditions should apply:
- A study dressing can be applied as prevention of a pressure ulcer category II or worse at that skin site (there is no contra-indication)
OR
- There is already a pressure ulcer category II or worse at that skin site.
Written informed consent by the patient or his/her legal representative.

Exclusion Criteria

Aged < 18 years.
The length of stay counting from first day of admission in one or (if the patient is transferred to another ward) more participating wards is < 7 days.
Both heels amputated
Previously known/documented allergy for substances used in the devices under study.
A clinical condition not allowing participation in a clinical study.
Participation in another interventional clinical trial.
Patients who exceptionally receive or are planned to receive a dressing for the prevention of pressure ulcers at sacrum, heels and trochanters based on best medical judgment and outside of the surgery setting.

Primary Outcome Measures

Name	Time	Method
Number of Participants Who Developed a New Pressure Ulcer Category 2 or Worse on Sacrum, Heels or Greater Trochanter	assessment during 14 days	The number of participants who developed at least one new pressure ulcer of category 2 or worse on sacrum, heels or greater trochanter as judged onsite, during the study period (maximum 14 days). Patients in experimental groups 1 and 2 were pooled as the treatment group and compared to the control group (in the intention to treat population (n=1605) Note: The International NPUAP/EPUAP Pressure Ulcer Classification System (National Pressure Ulcer Advisory Panel (2014)) distinguishes four categories of pressure ulcers: non-blanchable erythema of the intact skin (category I), partial thickness loss of dermis (category II), full thickness tissue loss (category III) and full thickness tissue loss with exposed bone, tendon or muscle (category IV). Also unstageable pressure ulcers and deep tissue injuries can be recognised. https://npiap.com/
