Introduction Research on research is key to enhancing efficacy in trial methodology. Clinical trials involving women during pregnancy and childbirth are limited, with a paucity of data guiding evidence-based practice. Following a prioritisation exercise that highlighted the top-ten unanswered recruitment questions, this qualitative evidence synthesis was designed specifically to focus on the barriers and enablers for clinicians/healthcare professionals in helping conduct randomised trials within the context of recruitment during pregnancy and childbirth. Methods The synthesis was undertaken using Thomas and Harden’s three stage thematic synthesis method and reported following the ENTREQ guidelines. Using a pre-determined SPIDER strategy, we conducted a comprehensive search of databases; Pubmed, CINAHL, PsycINFO, EMBASE, and grey searches for records until January 2019. We included all reports of qualitative data on recruiter’s experiences, perceptions, views of recruiting women during pregnancy and childbirth to clinical trials. Altogether 13,401 records were screened, resulting in 31 full-text reviews, of which five were eligible for inclusion. Quality was appraised using CASP. Data were extracted onto a specifically defined form. We used thematic synthesis to identify descriptive and analytical themes, and to interpret and generate theory. Confidence was assessed using GRADE-CERQual. The review protocol is publicly available (OSF https://osf.io/g4dt9/). Results Five papers (representing four individual studies) from two different countries were included. All studies focused on the experiences of trial recruiters in the maternity setting. We identified four analytical themes; Recruitment through a clinician’s lens, Recruiters judgement on acceptability, From protocol to recruiters lived experience, Framing recruitment in context. These were linked by an overarching theme combining beliefs and power. Conclusion The overarching theme combining beliefs and power links the experiences and perceptions of recruiters. This synthesis shows a gap between the trial design study protocol and the recruiter’s lived experience. Strategies such as collaborative trial design, mitigating gatekeeping behaviours, and training may support recruiters in their endeavour.
