Efficacy of Indigenous Negative Pressure Wound Therapy (NPWT) in the Management of Diabetic Foot Ulcers in Rural Settings: A Prospective Interventional Study

Abstract: Background: Diabetic foot ulcers (DFUs) are a major cause of morbidity and healthcare burden, especially in low-resource rural settings. Negative pressure wound therapy (NPWT) is a proven adjunct in wound care; however, high costs and limited availability hinder its application in rural hospitals. This study evaluates the effectiveness of an indigenously assembled NPWT system in managing DFUs. Methods: A prospective interventional study was conducted on 120 patients with Wagner grade 1 and 2 diabetic foot ulcers. Indigenous NPWT systems were applied using sterilized foam, Ryle?s tube, and wall suction. Outcomes were evaluated based on granulation tissue development, pain scores, infection control, need for re-debridement, and amputation rates over a two-week period. Results: By day 14, 92% of patients showed significant granulation tissue development. Pain scores improved substantially (mean VAS score dropped from 6.4 to 2.1). Infection was controlled in over 85% of patients. Only 4 required re-debridement and 2 underwent amputations. Conclusion: Indigenous NPWT is a cost-effective and clinically efficient wound care modality in rural settings. Its implementation can substantially reduce the burden of DFUs and improve limb salvage outcomes.
