Abstract

Aim: The objective was to estimate the cost of care associated with two negative pressure wound therapy (NPWT) technologies used to treat patients admitted to the hospital with moderate-to-severe foot infections. Materials methods: A decision tree simulation model was developed to estimate the hospital costs associated with two different NPWT technologies: Cardinal Health™ PRO (NPWT-C) and V.A.C. ULTA™ (NPWT-K). Clinical data were obtained from a previously completed single-site prospective trial. One-way and probabilistic sensitivity analyses were performed to gauge the robustness of the results. Results: The total expected per-patient costs were US$41,206 (SD: US$8,194) for NPWT-C and US$44,439 (SD: US$8,963) for NPWT-K. Conclusion: This study found that NPWT-C was expected to minimize the total costs over the episode of treatment. Larger and more clinically diverse studies are recommended to confirm these findings.
