Taking the nursing home of a private tertiary hospital in Fujian Province as an example, based on the analysis framework of Relationship-Space-Function, this article examines how private medical and elderly care institutions provide with preparatory end-of-life care through internal cooperation, thereby affecting the life quality of the elderly in their later years. The study suggests: (1) Nursing homes have established quasi-family relationship and created a closed space, to promote a semi-institutionalized preparatory end-of-life care; (2) This practice has shortcomings such as lack of medical social workers, insufficient service relationship, limited service space, and limited effectiveness of preparatory end-of-life care; (3) To address these challenges, institutions can take full advantages of medical social workers, to link the caring relationships, and use professional methods, to connect the caring space, or make policy advocacy, to stabilize the effectiveness of preparatory end-of-life care.
