The work aims to explore the theoretical basis and practical form of integrated care and in-place aging under the background of global population aging, construct the service design strategies and establish the accessible, efficient and satisfactory in-place aging service system, to improve the quality of life and medical experience of community or family care for the elderly. Through literature comparison, case analysis and narrative research, the theoretical basis and innovation opportunities of in-place aging care were explored to construct corresponding design strategies. There are four feasible design strategies for in-place aging service, including establishing an interdisciplinary design cooperation team, participating in the design process and service process, creating a user-centered sustainable service delivery system and paying attention to the social and emotional needs of the elderly. Focusing on the needs of the elderly, the consistent and integrated care for in-place aging is provided, and the transformation from hospitals and sanatoriums to community or family care is conceived based on service design thinking.
