BackgroundRecruitment to intrapartum research is complex. Women are expected to understand unfamiliar terminology and assess potential harm versus benefit to their baby and themselves, often when an urgent intervention is required. Time pressures of intrapartum interventions are a major challenge for recruitment discussions taking place during labour, with research midwives expected to present, discuss and answer questions whilst maintaining equipoise. However, little is known about these interactions. An integrated qualitative study (IQS) was used to investigate information provision for women invited to participate in the Assist II feasibility study investigating the OdonAssist™—a novel device for use in assisted vaginal birth with an aim to generate a framework of good practice for information provision.MethodsTranscripts of in-depth interviews with women participants (n= 25), with recruiting midwives (n= 6) and recruitment discussions between midwives and women (n= 21), accepting or declining participation, were coded and interpreted using thematic analysis and content analysis to investigate what was helpful to women and what could be improved.ResultsRecruiting women to intrapartum research is complicated by factors that impact on women’s understanding and decision-making. Three key themes were derived from the data: (i) a woman-centred recruitment process, (ii) optimising the recruitment discussion and (iii) making a decision for two.ConclusionDespite evidence from the literature that women would like information provision and the research discussion to take place in the antenatal period, intrapartum studies still vary in the recruitment processes they offer women. Particularly concerning is that some women are given information for the first time whilst in labour, when they are known to feel particularly vulnerable, and contextual factors may influence decision-making; therefore, we propose a framework for good practice for information provision for research involving interventions initiated in the intrapartum period as a woman centred, and acceptable model of recruitment, which addresses the concerns of women and midwives and facilitates fair inclusion into intrapartum trials.Trial registrationISRCTN.
