With the changing demographic structure, the incidence rate of chronic non⁃infectious diseases (hereinafter referred to as chronic diseases) continues to rise, making traditional chronic disease management modes inadequate to meet patient needs. The three⁃tier linkage continuous nursing mode, which integrates resources from hospitals, community health service centers, and households to provide full⁃cycle chronic disease management services, can significantly improve patients' treatment compliance and quality of life. This paper reviews the operation mechanisms of the three⁃tier linkage continuous nursing mode at different stages of chronic diseases, as well as its application effects and challenges in managing various chronic diseases, aiming at providing a theoretical basis for improving China's chronic disease management system.
