ObjectivesThe objectives of this scoping review are to: (1) identify the distribution of and context of the recruitment strategies used, (2) explore the facilitators, benefits, barriers and ethical issues of the identified recruitment strategies, (3) distinguish the varying terminology for involvement (ie, panels, boards, individual) and (4) determine if the individual recruitment strategies used were to address issues of representation or bias.DesignA scoping review.SettingThis scoping review follows the framework by Peterset al. Seven electronic databases were explored including Scopus, Medline, PubMed, Web of Science, CINAHL, Cochrane Library and PsycINFO (conducted July 2021). The search strategy was codeveloped among the research team, PPI research experts and a faculty librarian. Two independent reviewers screened articles by title and abstract and then at full text based on predetermined criteria.Primary and secondary outcome measuresExplore recruitment strategies used, facilitators, benefits, barriers and ethical issues of the identified recruitment strategies. Identify terminology for involvement. Explore recruitment strategies used to address issues of representation or bias.ResultsThe final sample was from 51 sources. A large portion of the extracted empirical literature had a clinical focus (37%, n=13) but was not a randomised control trial. The most common recruitment strategies used were human networks (78%, n=40), such as word of mouth, foundation affiliation, existing networks, clinics or personal contacts. Within the reviewed literature, there was a lack of discussion pertaining to facilitators, benefits, barriers and ethical considerations of recruitment strategies was apparent. Finally, 41% (n=21) of studies employed or proposed recruitment strategies or considerations to address issues of representation or bias.ConclusionWe conclude with four key recommendations that researchers can use to better understand appropriate routes to meaningfully involve patients, carers and members of the public to cocreate the evidence informing their care.
