This study aimed to improve nursing education in the field of lumbar surgery. Our medical center contains three neurosurgery wards, where the nursing staff provides pre- or post-surgical education for the care of patients undergoing lumbar surgery, based on the guidelines developed by the nursing department. However, the implementation rate of the guidelines was 70% because of a lack of standard nursing guidelines, of an undetailed and unfocused guidance sheet, of the lack of an audit system, the contents of the teaching CD were extensive. After conducting the questionnaire-based survey, matrix analysis, and literature verification, the contents of the improvement project included standardizing the guidelines for the care of patients undergoing lumbar surgery, developing image-based guardianship, and simplifying and optimizing the contents of the guardianship CD. After the implementation of the project, lumbar surgery care guidance integrity rate increased to 99%, the project successfully achieved its objectives, and the quality of care was improved.
