Efficacy of Negative Pressure Wound Therapy Versus Conventional Moist Dressings on Diabetic Foot Ulcer Healing Trajectories

Background: Diabetic foot ulcers (DFUs) are severe, chronic complications of diabetes carrying a high risk of amputation. While Negative Pressure Wound Therapy (NPWT) is an active biophysical treatment, clinical evidence using multidimensional tools in Middle Eastern settings like Jordan has been limited. Methods: A 3-month randomized controlled trial (January-May 2026) was conducted at the National Center for Diabetes, Endocrinology, and Genetics (NCDEG) in Amman, Jordan, involving 60 patients with chronic DFUs. Participants were randomized to either an intervention group receiving NPWT (80-125 mmHg, changed every 4 days) or a control group receiving conventional moist dressings (changed every 2 days). Wound trajectories were assessed using the 13-item Bates-Jensen Wound Assessment Tool (BWAT©).
