Loneliness at end‐of‐life: A scoping review

Abstract

AbstractAims and ObjectivesTo map and synthesise the literature on loneliness at end‐of‐life and identify key knowledge gaps in loneliness research.BackgroundDeclined health conditions, reduced social engagement, loss of social roles, and fear of death may lead to loneliness at end‐of‐life. However, systematic information about loneliness at end‐of‐life is scant.MethodsThis scoping review followed the methodology proposed by Arksey and O'Malley. Nine electronic databases were searched from January 2001 to July 2022. Studies about loneliness at end‐of‐life were included. Two review authors independently screened and selected relevant studies and performed the data charting. The PAGER framework was employed to collate, summarise and report the results. The PRISMA‐ScR checklist was included.ResultsA total of 23 studies were included in this review (12 qualitative, 10 quantitative, and one mixed‐methods design). There was not reliable data about the prevalence of loneliness among adults at end‐of‐life internationally. Three or 20‐item UCLA loneliness scale was frequently used to measure loneliness. Factors predisposed adults at end‐of‐life to loneliness included passive and active withdrawal from social networks, inability to share emotions and to be understood, and inadequate support on spirituality. Four strategies were identified to alleviate loneliness, yet none have been substantiated in clinical trials. Interventions facilitating spirituality, social interactions and connectedness seem effective in alleviating loneliness.ConclusionsThis is the first scoping review on loneliness at end‐of‐life, synthesising evidence from qualitative, quantitative, and mixed‐methods studies. Loneliness among adults at end‐of‐life is under‐investigated and there is a prominent need to address existential loneliness at end‐of‐life.Relevance to clinical practiceAll nurses should proactively assess loneliness or perceived social isolation for clients with life‐limiting conditions, regardless of social networks. Collaborative efforts (e.g., medical‐social collaborations) to promote self‐worthiness, social engagement and connectedness with significant others and social networks are needed.Patient or Public ContributionNo patient or public involvement.
