Abstract
Medical institutions provide guidance on caring skills for home caregivers. Oral teaching is combined with graphical tools in a method that has been proved to be an effective way of quickly mastering home caring skills and promotes effective learning for home caregivers. The graphic design and operation contents of this method are constantly revised through interviews and observations, and by carrying out home care application graphics it forms a spiral structure of Plan-Do-Study-Act (PDSA) participatory action research (PAR). In the three cycles of the operation of PDSA PAR, the designers accurately create graphics of the caring details based on the nurses' demonstrations and develop health education tools that are suitable to provide continuous assistance and services in real-life situations. PAR combined with PDSA, in each of the three cycles of the operation-design personnel, medical personnel and home caregiver personnel, respectively-as the lead roles, guide the planning decisions for PAR. This study is a reference for the improvement and development of medical graphics for health education tools to improve accuracy.
