Abstract: The article takes Brighton and Hove in UK as an example to demonstrate the roles and characteristics of the entrusted management party, service providers, and supervisory party in the implementation of the medical and social elderly care integration project in the UK, in order to analyze the difficulties faced by the integration of the medical and social elderly care systems in the community. The article believes that the integrated care services aim to break through the barriers between the medical and the social elderly care of local governments, and achieve integration from two aspects: organizational structure and policy delivery methods. In the organizational system, attempts are to achieve "strip" and "block" cooperation, leverage services through institutional and financial collaboration. The service delivery model emphasizes the implementation in the community and the establishment of partnership platforms for all parties. The supervision system is comprehensive. The implication includes care system integration based on human needs, partnership platform building, and supervision system improvement.
