Objectives: This systematic review and meta‐analysis aimed to determine the prevalence of loneliness and social isolation among informal carers of individuals with dementia and to identify potential influencing factors. Methods: We conducted a comprehensive search across 10 electronic databases, including PubMed, Cochrane, Embase, Web of Science, PsycINFO, CINAHL, Scopus, Chinese Biomedical, China National Knowledge Internet, and WANFANG. Our search strategy covered the inception of the databases up to September 16, 2023, with an updated search conducted on March 8, 2024. Prevalence estimates of loneliness and social isolation, presented with 95% confidence intervals, were synthesized through meta‐analysis. Subgroup analyses and meta‐regression were employed to explore potential moderating variables and heterogeneity. Results: The study encompassed 27 research papers involving 11,134 informal carers from 17 different countries. The pooled prevalence of loneliness among informal carers of individuals with dementia was 50.8% (95% CI: 41.8%–59.8%), while the pooled prevalence of social isolation was 37.1% (95% CI: 26.7%–47.6%). Subgroup analyses and meta‐regression indicated that various factors significantly influenced the prevalence of loneliness and social isolation. These factors included the caregiving setting, study design, the intensity of loneliness, geographical location (continent), data collection time, and the choice of assessment tools. Conclusions: This study underscores the substantial prevalence of loneliness and social isolation among informal carers of individuals with dementia. It suggests that policymakers and healthcare providers should prioritize the development of targeted interventions and support systems to alleviate loneliness and social isolation within this vulnerable population. Key points: Informal carers of people with dementia contend with unique circumstances that render them susceptible to both loneliness and social isolation.There is a significant prevalence of loneliness and social isolation in informal carers of individuals with dementia.Several significant moderators influence the prevalence of loneliness and social isolation among informal carers of individuals with dementia.Moderator analysis can guide targeted interventions and support systems for at‐risk informal carers of people with dementia to alleviate loneliness and social isolation.

Aims and objectives: To establish an understanding of healthcare professionals' dementia knowledge and attitudes towards dementia care, and family carers' perceptions of dementia care in China. Background: Healthcare professionals and family carers of people with dementia deliver most of the dementia care in China. However, little research on healthcare professionals' dementia knowledge and attitudes towards dementia care, and family carers' dementia care perceptions has been conducted in China. Methods: An integrative review was conducted and reported based on the PRISMA guidelines and Whittemore and Knafl's framework. Eight English databases were searched without date restriction: CINAHL Plus with Full Text, MEDLINE, PubMed, Web of Science, Cochrane Library, Embase, PsycINFO and Scopus; and three Chinese databases: China National Knowledge Infrastructure, Chongqing Weipu and Wanfang, plus a manual search of reference lists. Results: Thirty‐eight primary research papers were included in the review. Three themes were identified from the synthesis: (a) knowledge and competency; (b) attitudes towards dementia care; and (c) carers' burden and unmet needs. Healthcare professionals' dementia knowledge ranged from low to moderate levels and attitudes towards dementia care were generally negative. With low levels of knowledge of dementia and negative attitudes including stigma, family carers were under stress with insufficient support, and they expected more support from community nurses. Conclusions: There is an apparent need for a national policy on healthcare professional education and training to improve dementia care practice in China. Such a policy may improve support services for family carers. Relevance to clinical practice: Nurses, and particularly community nurses, are well‐positioned to support family carers in China. However, healthcare professionals in China are not prepared for this. Therefore, education and training on dementia care should be integrated into medical and nursing undergraduate programmes and provided for healthcare professionals after commencing employment, and strategies to reduce stigma are needed.
