At present, the aging trend of China's population is accelerating, but there is still a particular mismatch in the level of medical care for the aging trend. The medical team and rehabilitation are independent of each other. If you are sick, you have to go back and forth frequently between your family, hospital, and rehabilitation institution, which delays treatment and increases the financial burden on family members. The separation of medical care and rehabilitation has also led to many elderly patients who have recovered from serious illnesses or need long-term recuperation and will find various reasons to refuse to leave the hospital once they are admitted to the hospital. Therefore, the development of the integration of medical care and nursing needs to be accelerated. At present, several comparative paradigms of medical and elderly care integration models have initially formed in various parts of China: "institutional", "community", and "home" and other integrated medical and elderly care models. According to the research, in the process of practice, there are still imperfections in the integration of medical care and elderly care, such as supply and demand, service, supervision, and institutional cooperation, which can be improved by improving the supervision system, integrating medical care resources, standardizing industry standards, and cultivating service personnel.
