Evidence-based chronic ulcer care and lower limb outcomes

Evidence-based chronic ulcer care and lower limb outcomes among Pacific Northwest Veterans. – PubMed – NCBI.

These data from our colleagues at the Puget Sound VA and University of Washington provide some important findings for all ulcer types. Some intriguing tidbits:

1. Debridement of Diabetic Foot Ulcers imparts a 2.5-fold greater chance of healing.

2. Wound healing rates double when circulation is assessed at the first visit

Abstract

Evidence-based ulcer care guidelines detail optimal components of care for treatment of ulcers of different etiologies. We investigated the impact of providing specific evidence-based ulcer treatment components on healing outcomes for lower limb ulcers (LLU) among Veterans in the Pacific Northwest. Components of evidence-based ulcer care for venous, arterial, diabetic foot ulcers/neuropathic ulcers were abstracted from medical records. The outcome was ulcer healing. Our analysis assessed the relationship between evidence-based ulcer care by etiology, components of care provided, and healing, while accounting for Veteran characteristics. A minority of Veterans in all three ulcer-etiology groups received the recommended components of evidence-based care in at least 80% of visits. The likelihood of healing improved when assessment for edema and infection were performed on at least 80% of visits (hazard ratio [HR]=3.20, P=0.009 and HR=3.54, P=0.006, respectively) in patients with venous ulcers. There was no significant association between frequency of care components provided and healing among patients with arterial ulcers. Among patients with diabetic/neuropathic ulcers, the chance of healing increased 2.5-fold when debridement was performed at 80% of visits (P=0.03), and doubled when ischemia was assessed at the first visit (P=0.045). Veterans in the Pacific Northwest did not uniformly receive evidence-based ulcer care. Not all evidence-based ulcer care components were significantly associated with healing. At a minimum, clinicians need to address components of ulcer care associated with improved ulcer healing. This article is protected by copyright. All rights reserved.
