Objective To evaluate the effectiveness of a twice-daily application of a wipe impregnated with emollient and barrier ingredients in reducing incidence of pressure injury (PI) in aged care consumers. Design A single-blinded, multicentre randomised controlled trial. Randomisation was stratified by facility, using simple 1:1 randomisation within each stratum. Setting 20 residential aged care facilities in Rural and Metropolitan New South Wales and the Australian Capital Territory, Australia. Participants 858 aged care consumers aged ≥65 years at risk of developing a PI. Intervention Participants were randomised 1:1 to receive either standard hygiene practices, repositioning and use of pressure redistribution surfaces (standard care) or twice-daily applications of a pre-packaged wipe impregnated with emollient and barrier ingredients (Contiplan) to the sacrum, buttocks and heels in addition to standard care for the study duration. Primary outcome and analysis The primary outcome was the incidence of PIs per 1000 consumer days. Treatment effects were estimated using an intention-to-treat approach, with the absolute difference and 95% CI estimated using the Wald method. The relative difference in the incidence of PIs was estimated using a negative binomial regression model (with log link). Results 858 participants were included in the study. There was a 50% relative reduction in the incidence of PI in the intervention compared with the control (95% CI 0.31 to 0.81, p=0.005), with an absolute rate difference of 0.31 fewer PIs per 1000 consumer days (95% CI 0.11 to 0.51). Conclusion The use of wipes with emollient and barrier properties significantly reduced the incidence of PIs and prolonged the time to first PI, demonstrating efficacy as a PI preventive strategy in aged care.
