Abstract

Diabetic foot ulcers (DFUs) are a leading cause of morbidity and hospitalisation among patients with diabetes. We analysed claims data for Medicare part B diabetic foot ulcer patients treated with Negative Pressure Wound Therapy at home (N = 1135) and diabetic foot ulcer patients from a published meta-analysis of randomised controlled wet-to-moist therapy. The expected costs of care for the two treatments were also compared. A significantly greater proportion of wounds treated with NPWT achieved a successful treatment endpoint compared with wet-to-moist therapy at both 12 weeks (39.5% versus 23.9%; P < 0.001) and 20 weeks (46.3% versus 32.8%; P < 0.001). NPWT-treated patients reached a successful wound treatment endpoint more rapidly, and the benefit was apparent in all wound sizes. Expected 20-week treatment costs for NPWT were similar to those for wet-to-moist therapy if one nursing visit per day for the latter is assumed but 42% less if two nursing visits per day are made. Thus, NPWT may improve the proportion of DFUs that attain a successful wound treatment endpoint and decrease resource utilisation by a given health care system compared with standard wet-to-moist therapy.
