Brief Summary
This retrospective multi-site observational cohort study uses electronic health records (EHR) from U.S. wound care centers to evaluate the effectiveness of four amniotic membrane allografts (Acesso DL, Acesso TL, Neostim DL, Neostim TL) when added to standard wound care for diabetic foot ulcers (DFU), venous leg ulcers (VLU), and pressure ulcers (PU). The primary endpoint is complete wound closure by 12 weeks. Secondary outcomes include time-to-closure, ≥50% wound-area reduction at 4 weeks, wound-related complications (infection, hospitalization, emergency department visits, and major/minor amputation).
