Evaluation of a Switchable Acrylic Adhesive Drape for Safer Removal in Negative Pressure Wound Therapy Applications.

Negative pressure wound therapy (NPWT) is widely used for chronic and acute wounds, severe burns, and post-operative care. Despite its benefits, the strong adhesive required to maintain an airtight seal increases the risk of medical adhesive-related skin injuries (MARSI), pain, and discomfort during removal. Global Biomedical Technologies (GBT) aims to develop an NPWT drape with "switchable adhesive" technology to enhance removal while maintaining an effective seal. This innovation is expected to benefit both single-use and serial-use NPWT applications by reducing MARSI and improving patient comfort. This project will compare the functionality and acceptability of Comfort Release® NPWT drapes with the industry-standard V.A.C. drape (KCI Technologies, Inc.), or other facility standard drape, in a non-blinded randomized controlled trial. Specific Aims Aim 1: Compare Comfort Release® drapes with V.A.C. drapes in single or short-term use NPWT applications in post-surgical patients (n=200) at Columbia University Medical Center, Weill Cornell Medical Center, and Absolute Medical Center. Milestones: Demonstrate statistically significant (α=0.05) improvement over V.A.C. drapes in: Reduction of MARSI (Medical Adhesive-Related Skin Injury scoring system) Decreased pain (Indiana Polyclinic Combined Pain Scale) Reduced need for pain/anxiety medication Equivalent or improved seal effectiveness (leak incidence rate) Clinician acceptability Reduced nursing time by ≥20% Economic value through time and cost savings Aim 2: Compare Comfort Release® drapes with V.A.C. drapes in serial-use NPWT applications in chronic wound patients (n=100) at Weill Cornell Medical Center, Vital Medical Research, and All South Bay Footcare. Patients will undergo approximately three NPWT drape changes per week. Milestones: Demonstrate statistically significant (α=0.05) improvement over V.A.C./or standard drapes in: Reduction of MARSI Decreased pain (Indiana Polyclinic Combined Pain Scale) Improved
