The purpose of this study was to retrospectively analyze the wound condition, limb condition, ulcer recurrence and cardiovascular and mortality of patients with diabetic foot ulcer after admission to our hospital from 2009 to 2014, so as to understand the changes in the condition of patients with diabetic foot ulcer after treatment, provide evidence for the treatment of diabetic foot, and clarify the risk of diagnosis and treatment of diabetic foot.

Diabetic foot ulcer (DFU) is one of the most common and serious complications in patients with diabetes. Due to its high incidence and complicated treatment process, DFU often has a significant impact on patients' quality of life. In order to gain an in-depth understanding of the wound changes of diabetic foot patients after admission, this study aims to systematically analyze the data of the database of diabetic foot patients in Ruijin Hospital, analyze the wound healing, ulcer recurrence and limb changes of diabetic foot patients, including amputation and other conditions, and then further determine the main factors affecting diabetic foot ulcer healing. Guide clinicians to develop more effective treatment plans; Provide data support to help optimize the treatment flow of diabetic foot and reduce length of stay and recurrence rates; To improve the overall treatment effect of diabetic foot patients and improve their quality of life.

Objective:

1. The wound condition, limb condition, ulcer recurrence and cardiovascular and mortality changes of patients with diabetic foot after treatment were analyzed to clarify the risk of diagnosis and treatment of the disease and provide evidence for the treatment of diabetic foot.
2. To assess the progress of wound healing in patients with diabetic foot after admission to hospital and identify key factors that promote or delay healing.
3. By comparing the effects of different treatment methods (such as drug therapy, surgical intervention, adjuvant therapy, etc.), the most suitable treatment strategy is found.
4. The incidence of complications during and after treatment was analyzed, and effective management strategies were discussed.

Methods:Through systematic analysis of the data from the database of diabetic foot patients in Ruijin Hospital, the wound healing, ulcer recurrence and limb changes of diabetic foot patients, including amputation, were analyzed, and then the main factors affecting diabetic foot ulcer healing were further determined.
