*Estimates are based on small study (N=12) VLU Debridement Approach Driven By Site Of Care; Sharp Remains SoC Across Wound Care Clinics Current Debridement Practices* Commentary “All DFU / VLU patients get sharp debridement. If they are able to tolerate it, it is probably the most effective debridement method of removing nonviable tissue, as well as bioburden in the wound. ” – Podiatrist #5 (Non-PI) 29% 29% Legend “Some of the wounds are more superficial, sometimes the topical agent alone is enough...if they are not responding, yeah, then we would have to step it up and go to a different method, probably add sharp debridement in ” – Dermatologist #2 (Non-PI) Source: OW Primary Research (6/2022) All VLU patients seen at WC clinics will undergo debridement In contrast, in home health setting only 1/3 VLUs are debrided; other 2/3 of patients have wounds that are caught and managed early by nurses, and thus can heal without needing debridement Choice of debridement technique is highly dependent on site of care Surgeons and clinicians at wound care clinics, regardless of medical specialty, perform sharp debridement as SOC for all patients In other specialty practices, such as dermatology, clinicians much more split between sharp vs. non-sharp Nursing home / home health settings depend enzymatic or autolytic While sharp is SoC at WC clinics, pain can be a barrier to use (particularly in VLUs), leading HCPs to defer to a topical instead Sharp + enzymatic / autolytic combinations are also commonly used, with sharp used as primary method (e.g. 1-2x per week) and topical as maintenance (applied in between sharp visits)
