Pilot Study to Assess Safety and Usability of the Kyron NPWT System

Background: There is an evident need for Negative Pressure Wound Therapy (NPWT) systems specifically designed for use in resource-constrained settings to aid in the treatment of open wounds. Methods: Prospective single-arm interventional pilot study of 14 patients with complex wounds was conducted at Kirtipur Hospital in Kathmandu, Nepal. A novel NPWT device, the Kyron Suction Unit, was used by 4 plastic surgeons. Primary outcomes were ease of use (10-point Likert scale) and device safety (adverse events recorded). Pain (Visual Analogue Scale score), quality of life (modified EuroQol Derived Single Index scores), and wound dimensions were recorded. Results: User ratings on the 10-point Likert scale indicated high confidence and ease of use: median confidence setting up the device of 1.0 [interquartile range (IQR), 1.0; mean 2.3], median confidence maintaining the device of 1.0 (IQR, 1.0; mean, 1.5), and median ease of disassembly of 1.0 (IQR, 1.0; mean, 1.4). Significant improvement in Visual Analogue Scale scores (P = 0.03), modified EuroQol Derived Single Index scores (P
