Smith+Nephew announce latest scientific data supporting new ALLEVYN™ COMPLETE CARE 5-Layer Foam Dressing for pressure injury prevention
Smith+Nephew (NYSE:SNN; LSE:SN), the global medical technology business, is pleased to announce exciting new data from Professor Amit Gefen and his research group published in the International Wound Journal,1 demonstrating the pressure injury prevention mechanism of action of ALLEVYN COMPLETE CARE Foam Dressing and its ability to absorb and dissipate friction and shear forces.
Pressure injuries are localized damage to the skin or underlying tissue, resulting from prolonged exposure to pressure in combination with shear forces.2This landmark study demonstrates that the new ALLEVYN COMPLETE CARE Foam Dressing absorbs 93% of mechanical energy into its internal layers. The study shows that the dressing absorbs and dissipates shear forces internally and layer-to-layer frictional sliding within the dressing. This mechanism of action can significantly help reduce the harmful stress concentrations that are known to cause pressure injuries, a clinical burden which costs the US healthcare system over $26.8bn every year.3
By using both Frictional Energy Absorber Effectiveness (FEAE) and Finite Element Modelling (FEM), the results confirmed the mechanism of action of ALLEVYN COMPLETE CARE Dressing in mitigating mechanical loading and protecting underlying soft tissue.
“These findings represent a significant step forward in pressure injury prevention,” said Amit Gefen, Professor of Biomedical Engineering at Tel Aviv University. “ALLEVYN COMPLETE CARE Dressing 's advanced biomechanical performance dissipates potentially harmful shear forces, which can help protect patients from factors that contribute to pressure injuries.”
' 'Pressure injuries are a complex and costly challenge, placing a heavy burden on both patients and healthcare systems, " said Rohit Kashyap, President, Advanced Wound Management at Smith+Nephew. “This publication showcases the distinct mechanism of action of ALLEVYN COMPLETE CARE Foam Dressing and its ability to dissipate shear forces, helping to protect more patients from the harm of pressure injuries.”
ALLEVYN COMPLETE CARE Dressing will be launched into the US advanced wound care market later in the year, followed by subsequent markets throughout 2026, and is indicated for the management of a range of wounds and pressure injury prevention. Building on the successful mechanism of action principles originally established by ALLEVYN LIFE Dressing,4 the new ALLEVYN COMPLETE CARE Foam Dressing demonstrated an increased Frictional Energy Absorber Effectiveness, up from 30-45% to 93%.
