A randomized controlled study design will be adopted, and more than 30 outpatients with diabetic foot ulcers are expected to be recruited. The control group will receive routine care, while the experimental group will receive a short message-based customized standardized diabetic foot ulcer patient education program after their outpatient visits. Subjects will be followed up for eight weeks, and the Mann-Whitney U test and Fisher's correct probability test will be used to evaluate the effectiveness of the intervention.

The diabetic foot ulcer need complex treatment, and is with poor prognosis, thus it consumes medical resources and impedes the quality of life of patients. Most of the time, patients are required to perform diabetic foot ulcer self-management at home. However, their self-management behaviors are inadequate.

The short message-based customized standardized patient education program combines several smartphone message-based standardized educational contents to construct a customized patient education program which is according to the needs of patients, thus providing individualized patient education in a timely manner. The short message-based customized standardized patient education program may improve the diabetic foot ulcers self-management behavior and the self-efficacy on diabetic foot ulcers self-management, thereby promoting wound healing and improving quality of life.

The purpose of this study is to develop a short message-based customized standardized diabetic foot ulcer patient education program, and to test the effect of the program on diabetic foot ulcer self-management behavior, self-efficacy, wound prognosis, and quality of life.

The innovation of this study are as follows：our intervention is the first program in the world that (1) provides timely and individualized patient education in a customized standardized way, and (2) provides short message-based patient education for prevention and treatment of diabetic foot ulcers.

A customized standardized patient education module will be developed, and then the effectiveness evaluation will be carried out. A randomized controlled study design will be adopted, and more than 30 outpatients with diabetic foot ulcers are expected to be recruited. The control group will receive routine care, while the experimental group will receive a short message-based customized standardized diabetic foot ulcer patient education program after their outpatient visits. Subjects will be followed up for eight weeks, and the Mann-Whitney U test and Fisher's correct probability test will be used to evaluate the effectiveness of the intervention.
