PRESSURE INJURY
Many hospitalised patients are at high risk of developing pressure injuries (PI). PI onset can be rapid, with injury of skin and/or tissue over bony prominences [A recent meta-analysis found the global prevalence of hospital-acquired pressure injury (HAPI) in adults was 8.4% [There is an increasing emphasis on the use of a range of PIP strategies, including the use of prophylactic dressings. These dressings have demonstrated clinical effectiveness in preventing PI in some patient populations and contexts [Cost-effectiveness analyses of prophylactic dressings are sparse. Two within-trial cost-analyses reported prophylactic dressings led to cost savings [This previous research led us to design a robust randomised controlled trial (RCT) trial to determine the clinical and cost-effectiveness of a prophylactic silicone foam border dressing in preventing sacral HAPI in hospitalised patients assessed at risk for PI. Process evaluation data will also be collected, to evaluate contextual factors (e.g. patient-, provider-, and system-level factors) that may have moderated the effect of an intervention [
