Brief summary
The aim of this randomized controlled trial is to test the efficacy of preventive dressings for pressure ulcer prevention.
Detailed description
Patients of intensive acute care and residents of institutional long-term care facilities are at high risk for developing pressure ulcers (PUs). PU standard prevention includes repositioning, early mobilization and the use of special support surfaces. The use of prophylactic dressings might reduce friction and shear forces and/or modify the microclimate of the skin and might therefore protect the skin and underlying tissues from pressure/deformation injury. The primary objective of this study is to determine if preventive silicone dressings (Mepilex® border) applied to the heels and to the sacrum in addition to PU standard prevention reduces PU incidence category II, III, IV, and deep tissue injury compared to PU standard alone in at risk hospital patients.
