Regarding long-term home care needs, nurses need to communicate effectively and reasonably when teaching home caregivers. Designers can assist medical staff and develop pictorial tools to enhance communication. The purpose of this study is to explore a theoretical basis from the perspective of designers, patients' home caregivers, and medical staff to construct a theoretical framework that can jointly develop pictorial health education tools and healthcare system. The qualitative methods, including in-depth interview and observation, are applied to this study; ground theory sets out to construct a framework from the verbatim transcript of the interviews. Based on interview results, six axial codes were extracted: (1) the method of interdisciplinary cooperation; (2) medical research ethics; (3) communication methods; (4) forms of health education tools; (5) development of health education tools; (6) home care intubation procedure. Eight groups of home caregivers offered suggestions from their experiences. The designers need to assist medical staff to solve real problems, pay attention to professional norms, and forms of cooperation. Health education tools need to meet the needs of medical staff and home caregivers and designers should pay attention to the processes of communication. This study can also assist in interdisciplinary cooperation to explore the theoretical basis of pictorial health education tools for nurses in the context of long-term care at home.
