Integration has become a major concern for governments, healthcare and aged care systems in many countries. However, the research on and implementation of integrated care in China started relatively late, and there is no review on the needs of older adults with regard to integrated care and the influencing factors. Therefore, this paper aims to provide a scoping review by searching, evaluating, and summarizing the Chinese and international literature on the need for and the factors influencing integrated care for older people. In addition, this review highlights evidence of the gap between China and the world in integrated care.
