Peer Support for Patients With Diabetic Foot Ulcers

Of the estimated 30 million people in the U.S. with diabetes, 34% will develop a DFU in their lifetime, and 50% of those with a DFU have concurrent PAD. Foot ulceration, which precedes 80% of amputations in diabetics, is associated with impaired physical function, reduced quality of life, and increased risk of death. Moreover, PAD, DFU, and subsequent major amputations are unevenly patterned in terms of racial/ethnic, SES, health insurance, and geographic status. More specifically, Black and Hispanic adults with an ischemic DFU have a higher prevalence of amputation than their White counterparts. The mechanisms of these observed disparities in amputation, beyond disease severity and comorbidities, are complex. However, evidence indicates that ulcer care (including wound care, diabetic shoe, offloading, and recognizing warning signs) is a significant challenge for low-income patients with an ischemic DFU. In addition, our team and other researchers have demonstrated how psychological, interpersonal, social, and healthcare system-level barriers limit appropriate ulcer and foot care. Furthermore, our qualitative data demonstrates a high rate of psychological and interpersonal factors to diabetic foot care that cannot be ignored. Clearly, there is a compelling need for innovative methods to improve DFU care that are based on health equity that led to diverse support. To address this gap, we propose a patient-centered and culturally tailored Peer-Pal Intervention (PPI) that helps promote ulcer care in patients with a DFU, while minimizing the burden placed on system resources.
