Unpaid cancer caregivers (UCCs) are the primary caretakers of individuals with cancer, often shouldering caregiver responsibilities without prior preparation, which leads to a sense of isolation, particularly in remote and rural areas where healthcare access is challenging. Thus, this systematic review aimed to explore the perceived and/or received peer support needs of UCCs residing in rural and remote areas with a specific focus on informational, practical, and emotional needs.

Seven databases (CINAHL, ScienceDirect, PUBMED/MEDLINE, PROQUEST, Web of Science, Scopus, and Informit) were searched from 2004 to 2024. Peer-reviewed qualitative, quantitative, and mixed-method studies published in English were considered for this review. Data were extracted using the Joanna Briggs Institute System for Unified Management, Assessment, and Review of Information and presented using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram. Quality and bias were assessed with the Mixed Methods Appraisal Tool.

In total, 8 primary studies were included: 4 qualitative, 2 mixed methods, 1 cross-sectional, and 1 prospective survey. Four themes were identified: (1) Emotional, practical, and informational unmet needs; (2) Lack of peer support on the physical and emotional well-being of UCCs in remote and rural areas; (3) Lack of supportive services in remote and rural areas; and (4) Access to flexible peer support.

This review revealed the unique unmet needs of UCCs in remote and rural areas, where a lack of reliable and accessible resources adversely leads to impaired UCCs’ overall well-being. Addressing these unmet needs is essential to enhance the support system for UCCs living in such regions. By identifying the gaps, the review underscores the need for developing a peer support model tailored to the specific needs of UCCs in rural and remote communities.
