Little is known about the impact of peer support programmes on physical health populations or on the methods used to evaluate such programmes. The present study undertakes a scoping review of research related to peer support programmes or interventions in physical health populations, guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews (PRISMA-ScR). The search was carried out across the Medline, PsycINFO, and Cochrane databases and focused on papers that evaluated peer support intervention(s) in adults with physical health conditions. The search identified an initial 7,903 records, which were narrowed down to 21 records that met the inclusion criteria; their findings were narratively synthesized. The scoping review found considerable heterogeneity among eligible records in terms of their study design, outcome measurements and findings reported. Qualitative methods of evaluation generated more consistent findings compared to objective outcome measures and suggested that peer support was beneficial for patients' health and wellbeing by reducing feelings of isolation and creating a sense of community as well as providing an opportunity for information consolidation. The scoping review highlights the inconsistencies in methods used to evaluate peer support interventions and programmes in healthcare settings among different physical health populations. It also draws attention to the lack of peer support research in particular areas, including in acute physical health populations such as in major trauma. The scoping review emphasizes the need for future studies to address this gap in peer support research.
