Abstract: The prevalence of hearing impairment in older people with community-based home care is increasing，which has a negative impact on their quality of life，cognitive function and social behaviors，so it is of great significance to take measures to prevent and reduce such negative impacts. It has been found that the use of hearing aids effectively improves hearing level and sociability，as well as cognition，memory and perception of language in older people with community-based home care. However，relevant research is still in its infancy and there is no systematic review about it. We reviewed the latest studies on the use of hearing aids in older people with community-based home care，encompassing the overview of hearing impairment and hearing aids，current status and existing problems regarding the use of hearing aids in older people with community-based home care，and cognitive features of this group，as well as impact of using hearing aids on their cognitive function，then put forward recommendations facilitating the extensive use of hearing aids in this group，including hearing aids research and making，development of supportive policies to promote the development of hearing aid industry，the fostering of hearing care professionals，and the enhancement of high-risk individuals' knowledge，attitude and use regarding hearing aids，clinical study of the effect of hearing aids，and hearing aid related services.
