[Older people living alone: the importance of informal non-kin care : Scoping review].

Background: The number of older people living alone is constantly increasing. This group faces special challenges regarding remaining at home when their care needs increase, especially in later life. When no family is available, friends and neighbors, so called non-kin carers, are important sources of support.

Objective: A literature review was conducted to evaluate existing research on the relevance of non-kin support for older people living alone, from initial limitations to the end of their lives, particularly when they wished to remain at home.

Method: The literature search followed the criteria of a scoping review and was conducted in relevant databases and manually. A total of 22 studies were included in the analysis.

Results: Older people living alone are often embedded in complex support networks. Living alone at an advanced age creates tensions between the desire for independence and the need for help. Non-kin carers primarily provide instrumental, emotional, and informational support. Challenges arise due to difficult interpersonal dynamics and the overburdening of non-kin carers, especially when those they support are at the end of their lives.

Conclusion: It is important to understand care networks as a complex interplay of different actors. Future research should focus on the specific burdens on non-kin carers as well as on the dynamics of relationships in these care networks.
