Diabetes is a significant health problem affecting approximately half a billion people worldwide, reaching alarming levels. Diabetic foot ulcers are among the most common and serious complications of diabetes. Diabetes is the most common cause of end-stage renal failure, and diabetic nephropathy is identified as a major risk factor for foot ulcers and amputation. The health belief model is a model that explains behavior. Focusing on the necessary motivational resources for the development of positive health behaviors in individuals is crucial for positive patient outcomes in the education of diabetic hemodialysis patients. It is necessary for hemodialysis nurses to educate diabetic patients on foot care knowledge, improve foot care behaviors, and prevent the development of foot ulcers and lower extremity amputations. However, the lack of studies in the literature on nurse-led foot care education interventions based on the health belief model for diabetic patients undergoing hemodialysis constitutes the strength and unique aspect of this study. The research will be conducted using a randomized controlled pretest-posttest design.
