Updated activity approved: February 1, 2020
CME Expires: January 31, 2023

Target Audience
This module is designed for anyone who wishes to learn more about diagnosis and treating patients with lower extremity ulcers. This includes students, medical assistants, nursing staff, and physicians. 

The two components of the limb salvage education module are designed to train those who care for patients with lower extremity wounds and allow them to quickly understand if patients need a procedure to improve blood flow in order to heal these wounds. The ankle brachial index course provides a comprehensive overview of how the ABI test is done, billing and wave form analysis.  The WIfI course allows for incorporation of the ABI with the physical exam to help providers understand the potential for wound healing and if improvement in blood flow is needed. This information allows patients to then understand their risk of limb loss at the first visit. 


WIfI Participants will be able to characterize a patients’ risk of amputation and need for revascularization using the WIfI tool.


Learning Objectives
At the end of this module, the learner will be able to:
  1. List amputation trends in the United States for patients with diabetes mellitus and peripheral artery disease
  2. Describe the WIfI scoring tool
  3. Discuss the correlation with amputation risk and need for a revascularization procedure
  4. Successfully apply the WIfI tool on stored patient images
