267-OR: Assessing Patient Knowledge about Diabetic Foot Ulcer Offloading

Abstract

Introduction: Standard of care for diabetic foot ulcers (DFU) includes wound debridement, dressing changes, diabetes control, and offloading. Despite this, half of all patients fail to heal when standard of care is met. Offloading DFU is critical to promote wound healing, yet patient adherence is undesirably low and contributes to failed wound healing. We evaluated patient knowledge of DFU offloading through a voluntary telephone survey. Methods: Participants were recruited from a tertiary care center podiatry department and completed a 21-item telephone survey. All subjects had a history of diabetes and were included regardless of DFU history. Descriptive statistics and chi square were calculated to evaluate survey responses. Results: Currently 92 of 167 subjects (55.1%) completed the telephone survey. All subjects regardless of DFU history correctly identified DFU increases risk of amputation (DFU95.7%; n=88/92). All subjects regardless of DFU history identified “offloading” and “pressure relief” as important factors to improve DFU healing (97.8%; n=90/92; 98.9%; n=91/92, respectively). Only a minority (43.5%; n=40/92) of participants were able to correctly identify the best offloading strategy, regardless of DFU history (DFU history 48.5%; n=16/33 vs. No DFU history 40.7%; n=24/59; p=0.5155). Discussion: We hypothesized people with a history of a DFU would understand the concept of offloading better, but yet patients who had a history of a DFU were as likely to misunderstand the term “offloading” compared to patients who have no history of a previous DFU. Our findings importantly identify a gap in patient education surrounding an essential component of DFU standard of care. Disclosure R. A. Burmeister: None. C. Holmes: None. C. Jarocki: None. T.
