Patients having correct knowledge and ability of self-care for wound can reduce the risk complications. However, nursing education for wound care is incomplete due to work load and variation of patients and environment. There are two reasons that patients have low accuracy on ability of self-care for wound. First, patients are not able to accept the guidance in the content of health education. Second, there is no standard process of nursing education and a monitoring system. Therefore, the purpose of this project is to promote accuracy on self-care for wound of trauma patients before discharge. Patients are able to learn knowledge and skills of self-care step by step by improving nursing education completely. Furthermore, using textured manual and check list to standardize the process of nursing education facilitate patients' ability of self-care. Lastly, the accuracy of self-care for wound of patients improved from 73.8% to 92.7% after implementing this project.
