What works in peer support for breast cancer survivors: A qualitative systematic review and meta‐ethnography

Abstract Breast cancer is associated with adverse physical and psychological consequences. Although research has identified the various benefits linked to psychosocial interventions, mixed results have been found in relation to peer support. The aim of the present systematic review and meta‐ethnography is to explore the qualitative evidence on the experience of breast cancer survivors in peer support. A systematic search of the literature was conducted until June 2023, and a meta‐ethnographic approach was used to synthesize the included papers. Eleven articles were included, collecting the experience of 345 participants. The following four core areas involved in peer support implementation were identified from the synthesis: Peer support can create understanding and a mutual therapeutic and emotional connection; peer support can facilitate an educational and supportive patient‐centered journey; peer support should monitor group members for unpleasant emotional experiences; peer support should have professional supervision of recruitment and training to prioritize quality. These results can be used as patient‐centered insights by healthcare professionals to provide evidence‐informed peer support programs and address current limitations in the field.
