Objective: To identify the cross-cultural experiences of family members, including foreigners, who support patients. Methods: We conducted a literature review using seven databases. Results: Three articles from Japan and seven from other countries were reviewed. From these articles, 23 descriptions of the experiences of family members because they had a different lifestyle or culture from the country in which a patient was receiving medical care were grouped into nine categories and then classified into three themes: Difficult experiences due to differences in religion/customs, Difficult experiences due to differences in language, and Experiences of personal/social support. Conclusions: It was clear that the cultural competence of nurses, the establishment of a system for family caregivers to provide a sense of accomplishment and satisfaction when providing care, and the creation of a cooperative community regardless of nationality and culture are important. We believe that nursing support measures that involve communities for family members who are supporting a patient in the family including foreigners, are necessary to maintain mental and physical health.
