Abstract

The Society for Vascular Surgery Lower Extremity Threatened Limb Classification System has been developed to stratify amputation risk on the basis of extent of the wound, level of ischemia, and severity of foot infection (WIfI). However, there are no currently validated metrics to assess, grade, and consider functional status, especially ambulatory status, as a major consideration during limb salvage efforts. Therefore, we propose an adjunct to the current WIfI system to include the patient's ambulatory functional status after initial assessment of limb threat. We propose a functional ambulatory score divided into grade 0, ambulation outside the home with or without an assistive device; grade 1, ambulation within the home with or without an assistive device; grade 2, minimal ambulation, limbs used for transfers; and grade 3, a person who is bed-bound. Adding ambulatory function as a supplementary assessment tool can guide clinical decision making to achieve optimal future functional ambulatory outcome, a patient-centered goal as critical as limb preservation. This adjunct may aid limb preservation teams in rapid, effective communication and clinical decision making after initial WIfI assessment. It may also improve efforts toward patient-centered care and functional ambulatory outcome as a primary objective. We suggest a score of functional ambulatory status should be included in future trials of patients with chronic limb-threatening ischemia.
