IVF treatment involving donated eggs increases yearly. Numerous technical and commercial transformations have reshaped how eggs are retrieved, stored and managed. A key transformation is vitrification; a 'fast freezing' method that allows efficient preservation of eggs, and therefore more flexibility in use, giving rise to new commercial possibilities. There has been limited focus on egg providers' experiences in the context of vitrification and related commercialisation. We report findings from a study in the UK, Spain and Belgium, where we interviewed 75 egg providers. Comparing experiences within different donation 'regimes' allows an exploration of how varying national practices and policies shape information-giving and women's experiences. In the UK, a system of 'informed gift-giving' was described, where egg providers saw their actions as not-for-profit and felt relatively well informed. In Belgium, the system was presented as 'trusted tissue exchange': with less information-giving than in the UK, but clinics were trusted to act responsibly. In Spain, a 'closed-door, market-driven' system was described, whereby egg providers received little information and expressed concerns about generation of excess profit. Our findings extend understandings of how egg donation is managed at the national level and how donation regimes produce specific experiences, expectations and subjectivities amongst tissue providers., (© 2022 The Authors.

Background: Referral and uptake rates of structured self-management education (SSME) for Type 2 diabetes (T2DM) in the UK are variable and relatively low. Research has documented contributing factors at patient, practitioner and organisational levels. We report a project to develop an intervention to improve referral to and uptake of SSME, involving an integrative synthesis of existing datasets and stakeholder consultation and using Normalisation Process Theory (NPT) as a flexible framework to inform the development process., Methods: A three-phase mixed-methods development process involved: (1) synthesis of existing evidence; (2) stakeholder consultation; and (3) intervention design. The first phase included a secondary analysis of data from existing studies of T2DM SSME programmes and a systematic review of the literature on application of NPT in primary care. Influences on referral and uptake of diabetes SSME were identified, along with insights into implementation processes, using NPT constructs to inform analysis. This gave rise to desirable attributes for an intervention to improve uptake of SSME. The second phase involved engaging with stakeholders to prioritise and then rank these attributes, and develop a list of associated resources needed for delivery. The third phase addressed intervention design. It involved translating the ranked attributes into essential components of a complex intervention, and then further refinement of components and associated resources., Results: In phase 1, synthesised analysis of 64 transcripts and 23 articles generated a longlist of 46 attributes of an embedded SSME, mapped into four overarching domains: valued, integrated, permeable and effectively delivered. Stakeholder engagement in phase 2 progressed this to a priority ranked list of 11. In phase 3, four essential components attending to the prioritised attributes and forming the basis of the intervention were identified: 1) a clear marketing strategy for SSME; 2) a user friendly and effective referral pathway; 3) new/amended professional roles; and 4) a toolkit of resources., Conclusions: NPT provides a flexible framework for synthesising evidence for the purpose of developing a complex intervention designed to increase and reduce variation in uptake to SSME programmes in primary care settings., (© 2022.
