Abstract: This study aims to investigate the problem of poor coordination of medical-nursing care information for the elderly between medical institutions and pension institutions, which makes it difficult to provide higher quality smart medical-nursing care integration services. It is expected to provide new ideas and models for the elderly medical-nursing care information to realize cross-chain collaboration between medical institutions and pension institutions. First, based on the characteristics of different types of blockchain, the current study proposed the elderly’s medical health information alliance chain and the elderly’s pension care information alliance chain within the medical association, providing a content module for the subsequent construction of the cross-chain collaboration model of smart medical-nursing care information. Secondly, by analyzing the advantages and disadvantages of the current mainstream cross-chain technology in blockchain, this study focused on the Polkadot cross-chain technology, which is suitable for realizing the cross-chain collaboration of smart medical-nursing care information and can provide the optimal link for the subsequent construction of the cross-chain collaboration model of smart medical-nursing care information. Finally, based on the principles of human-centered, systemic and developmental view, this study adopted a component-based and modular design concept to build a cross-chain collaboration model of smart medical-nursing care information based on Polkadot blockchain technology, and analyzed its advantages and challenges. Based on the Polkadot cross-chain technology, the cross-chain collaboration model of smart medical-nursing care information can promote the cross-chain collaboration of the elderly’s medical health information and the elderly’s pension care information on the premise of protecting the privacy and security of the elderly.
