Background: A core outcome set could address inconsistent outcome reporting and improve evidence for stillbirth care research, which have been identified as an important research priority. Objectives: To identify outcomes and outcome measurement instruments reported by studies evaluating interventions after the diagnosis of a stillbirth. Search strategy: Amed, BNI, CINAHL, ClinicalTrials.gov, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase, MEDLINE, PsycINFO, and WHO ICTRP from 1998 to August 2021. Selection criteria: Randomised and non‐randomised comparative or non‐comparative studies reporting a stillbirth care intervention. Data collection and analysis: Interventions, outcomes reported, definitions and outcome measurement tools were extracted. Main results: Forty randomised and 200 non‐randomised studies were included. Fifty‐eight different interventions were reported, labour and birth care (52 studies), hospital bereavement care (28 studies), clinical investigations (116 studies), care in a multiple pregnancy (2 studies), psychosocial support (28 studies) and care in a subsequent pregnancy (14 studies). A total of 391 unique outcomes were reported and organised into 14 outcome domains: labour and birth; postpartum; delivery of care; investigations; multiple pregnancy; mental health; emotional functioning; grief and bereavement; social functioning; relationship; whole person; subsequent pregnancy; subsequent children and siblings and economic. A total of 242 outcome measurement instruments were used, with 0–22 tools per outcome. Conclusions: Heterogeneity in outcome reporting, outcome definition and measurement tools in care after stillbirth exists. Considerable research gaps on specific intervention types in stillbirth care were identified. A core outcome set is needed to standardise outcome collection and reporting for stillbirth care research. [ABSTRACT FROM AUTHOR]

Background: Microplastics, produced through degradation of environmental plastic pollution, have been detected in human tissues including placenta and fetal meconium. Cell culture and animal studies have demonstrated potential reproductive toxicity of these particles; however, their association with adverse fertility or pregnancy outcomes in humans is not known., Objectives: To synthesise evidence for the presence of microplastics in human reproductive tissue and their associations with environmental exposures and reproductive outcomes., Search Strategy: MEDLINE, Embase, Emcare, CINAHL, ClinicalTrials.gov and ICTRP were searched from inception to 03/02/2023., Selection Criteria: Studies of human participants, assessing presence of microplastics in reproductive tissues, environmental exposures to microplastics, and fertility- or pregnancy-related outcomes., Data Collection and Analysis: Two independent reviewers selected studies and extracted data on study characteristics, microplastics detected, environmental exposures and reproductive outcomes. Narrative synthesis was performed due to methodological heterogeneity., Main Results: Of 1094 citations, seven studies were included, covering 96 participants. Microplastics composed of 16 different polymer types were detected in both placental and meconium samples. Two studies reported associations between lifestyle factors (daily water intake, use of scrub cleanser or toothpaste, bottled water and takeaway food) and placental microplastics. One study reported associations between meconium microplastics and reduced microbiota diversity. One reported placental microplastic levels correlated with reduced birthweights and 1-minute Apgar scores., Conclusions: There is a need for high-quality observational studies to assess the effects of microplastics on human reproductive health., (© 2024 The Authors.

Introduction: Stillbirth is associated with significant physical, psychosocial and economic consequences for parents, families, wider society and the healthcare system. There is emerging momentum to design and evaluate interventions for care after stillbirth and in subsequent pregnancies. However, there is insufficient evidence to inform clinical practice compounded by inconsistent outcome reporting in research studies. To address this paucity of evidence, we plan to develop a core outcome set for stillbirth care research, through an international consensus process with key stakeholders including parents, healthcare professionals and researchers., Methods and Analysis: The development of this core outcome set will be divided into five distinct phases: (1) Identifying potential outcomes from a mixed-methods systematic review and analysis of interviews with parents who have experienced stillbirth; (2) Creating a comprehensive outcome long-list and piloting of a Delphi questionnaire using think-aloud interviews; (3) Choosing the most important outcomes by conducting an international two-round Delphi survey including high-income, middle-income and low-income countries; (4) Deciding the core outcome set by consensus meetings with key stakeholders and (5) Dissemination and promotion of the core outcome set. A parent and public involvement panel and international steering committee has been convened to coproduce every stage of the development of this core outcome set., Ethics and Dissemination: Ethical approval for the qualitative interviews has been approved by Berkshire Ethics Committee REC Reference 12/SC/0495. Ethical approval for the think-aloud interviews, Delphi survey and consensus meetings has been awarded from the University of Bristol Faculty of Health Sciences Research Ethics Committee (Reference number: 116535). The dissemination strategy is being developed with the parent and public involvement panel and steering committee. Results will be published in peer-reviewed specialty journals, shared at national and international conferences and promoted through parent organisations and charities., Prospero Registration Number: CRD42018087748., Competing Interests: Competing interests: AW has received consulting fees from the Sillbirth CRE., (© Author(s) (or their employer(s)) 2022.

Objective: To develop global consensus on a set of evidence-based core principles for bereavement care after stillbirth., Methods: A modified policy-Delphi methodology was used to consult international stakeholders and healthcare workers with experience in stillbirth between September 2017 and October 2018. Five sequential rounds involved two expert stakeholder meetings and three internet-based surveys, including a global internet-based survey targeted at healthcare workers in a wide range of settings., Results: Initially, 23 expert stakeholders considered 43 evidence-based themes derived from systematic reviews, identifying 10 core principles. The global survey received 236 responses from participants in 26 countries, after which nine principles met a priori criteria for inclusion. The final stakeholder meeting and internet-based survey of all participants confirmed consensus on eight core principles. Highest quality bereavement care should be enabled through training of healthcare staff to reduce stigma and establish respectful care, including acknowledgement and support for grief responses, and provision for physical and psychologic needs. Women and families should be supported to make informed choices, including those concerning their future reproductive health., Conclusion: Consensus was established for eight principles for stillbirth bereavement care. Further work should explore implementation and involve the voices of women and families globally., (© 2020 International Federation of Gynecology and Obstetrics.)

Objective: Engaging bereaved parents in the review process that examines their care before and after a perinatal death might help parents deal with their grief more effectively and drive improvements in patient safety. The objective of this study is to explore whether healthcare professionals would accept or support parent engagement in the perinatal mortality review process., Design: Qualitative focus group interviews. Transcripts were analysed with an inductive thematic approach., Setting: Two geographically distinct tertiary maternity hospitals in the UK., Participants: Five focus groups were conducted with clinical staff including midwives, obstetricians, neonatologists, nursing staff and chaplaincy services., Results: Twenty-seven healthcare professionals unanimously agreed that parents' involvement in the perinatal mortality review process is useful and necessary. Six key themes emerged including: parental engagement; need for formal follow-up; critical structure of perinatal mortality review meeting; coordination and streamlining of care; advocacy for parents including role of the bereavement care lead; and requirement for training and support for staff to enable parental engagement., Conclusions: Healthcare professionals strongly advocated engaging bereaved parents in the perinatal mortality review: empowering parents to ask questions, providing feedback on care, helping generate lessons and providing them with the opportunity to discuss a summary of the review conclusions with their primary healthcare professional contact. The participants agreed it is time to move on from 'a group of doctors reviewing notes' to active learning and improvement together with parents, to enable better care and prevention of perinatal death., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2018.
