The experience of vasa praevia for Australian midwives: A qualitative study

Women- and clinician- important outcomes and priorities regarding vasa praevia: An international qualitative study to inform development of a core outcome set

BACKGROUND

Many studies have reported interventions for women with vasa praevia to improve perinatal outcomes. However, which outcomes are important for women remains unclear.

AIM

To explore what outcomes are important for women with lived experience of vasa praevia and why, in order to inform the development of a core outcome set for studies on vasa praevia.

METHODS

An international qualitative study was conducted with women and clinicians. Semi-structured interviews were audio-recorded, transcribed, and analysed taking an inductive approach.

FINDINGS

Eighteen women and six clinicians (four obstetricians, two midwives) from the United States, United Kingdom, Canada, and Australia were interviewed. Participants identified 47 patient-important outcomes and experience measures, which were grouped under five themes: baby's survival and health, mother's physical health, mother's mental and emotional health, quality of health care delivery, and resource use and cost. While survival of the baby without short- and long-term morbidity remained the main priority, other important considerations included the physical, mental, social and financial wellbeing of families, future access to antenatal screening and diagnosis, information on management options and consequences, continuity of care, clear and effective communication, peer support and the appreciation of individual variations to risk tolerance, values and resource availability.

CONCLUSION

We have identified patient-important outcomes and experience measures that have been directly fed into the development of a core outcome set on vasa previa. Incorporating these considerations into both clinical practice and future research studies has the potential to improve outcomes and experiences for women with vasa praevia.

Partners in Pain, Two Sides of a Zipper - Midwives' Experiences With Stillbirth: A Qualitative Study

This study was conducted to explore and understand the experiences of midwives who care for women experiencing stillbirth and the challenges they face in this process. A qualitative study was conducted with 11 midwives using the phenomenological method. Descriptive analysis of the data revealed four main themes: 1) Silent screams in the face of despair (women's reactions to stillbirth), 2) Being a partner in pain, "two sides of a zipper" (midwives' experience of stillbirth), 3) Efforts to cope with the pain, and 4) Just two words: "if only." The impact of stillbirths on midwives should not be disregarded. Emotions such as shock, horror, fear, guilt, and anger experienced by midwives following a stillbirth can adversely affect their mental health. The guilt experienced by midwives can also negatively impact their health and quality of life, as well as cause burnout and distancing from the profession.

The impact on midwives and their practice after caring for women who have a traumatic childbirth: A systematic review

BACKGROUND

Women's birth experiences can range from positive and satisfying to negative and traumatizing. Midwives caring for women can also be exposed to these traumatic childbirth experiences. There is a paucity of research on the impact these experiences have on midwives and their practice. The PEO framework guided the research review question.

METHODS

Seven electronic databases were systematically searched. The quality of each included study was assessed using the tool appropriate to the study's methodological approach; Critical Appraisal Skills Program (CASP) criteria and the Mixed Methods Appraisal Tool (MMAT) Version 2018. The Consolidated Criteria for Reporting Qualitative Research (COREQ) tool was utilized to assess reported findings. Confidence in the Evidence from Reviews of Qualitative research (CERQual) was used to grade the confidence in the evidence of the qualitative research. Data were thematically analyzed to formalize the identification and development of themes.

RESULTS

A total of 12 studies were included. Synthesis of the evidence generated one overarching theme, "Midwives, the forgotten victims", and three themes describing the essences of midwives' experiences: "Bruised and battered but still smiling"; "Wearing armour to protect my soul"; "Members of my team are holding me up, others are pulling me down".

CONCLUSIONS

Midwives expressed feelings of shock, fear, responsibility, and powerlessness which may contribute to some experiencing serious mental illness. They reported a shaken belief in the normal physiologic birth process which consequently led to more defensive practice. Research is needed to identify high-quality interventions to support midwives after these events. This systematic review protocol was registered on the International Prospective Register of Systematic Reviews (PROSPERO; Registration CRD42021252033).

Worker Experiences of the Work Health and Safety Impacts of Exposure to Dying and Death in Clinical Settings: A Qualitative Scoping Review

Workers employed in clinical healthcare settings often encounter dying and death of patients as a part of their role. This scoping review aimed to explore the physical and psychosocial OHS impacts on health workers exposed to death within their occupational role and their inherent coping strategies. Six electronic databases PsycINFO (Ovid), Medline (Ovid), AMED (EBSCO), CINAHL (EBSCO), and Proquest Social Sciences were searched for peer reviewed research articles published between March 1971 and April 2022. PRISMA-ScR guidelines were followed. Three authors independently assessed articles for inclusion. Fifty-three studies with focus settings in hospitals, hospice, general practice and residential care were identified. Five main themes were developed and organized using and ergonomic systems approach: Cultural Environment, Workplace, Job Demands, Impacts and Coping. The findings demonstrate that caring for dying patients, the dead and their families in clinical settings impacts workers emotionally, physically, behaviorally and spiritually.

Midwives' experiences of witnessing traumatic hospital birth events: A qualitative study

AIMS AND OBJECTIVES

The aim of this study was to investigate in detail the traumatic birth experiences of midwives in the delivery rooms, and their attitudes, reactions, and coping strategies.

METHODS

The design of the study is descriptive and the purposive sampling method was used. This approach is ideal for a preliminary exploration of the nature of a phenomenon. Between October 2018 and January 2019, semi-structured interviews were conducted with a purposeful sample of midwives. The research was carried out with the participation of 29 midwives, who work in labour and birth room. They were asked to describe a particular stressful situation they had experienced during the birth process, their emotions about the event, and their coping strategies and support systems. All interviews were digitally recorded, stored in a database, and transferred to MAX Qualitative Data Analysis 18.1.0 for analysis.

FINDINGS

As a result of the content analysis, three main themes emerged: psychological impact, defensive practice, and expectations in terms of support from the hospital. It was revealed that, after the traumatic birth, midwives experienced highly emotional exhaustion in the form of sadness, flashbacks, guilt, fear, and empathy, and they performed an increasingly defensive practice. During the interviews, we observed that 19 midwives needed psychological support. Besides, midwives explicitly stated that they were not prepared enough for traumatic events and that most traumatic births were simply ignored in their workplace. Eventually, it was determined that midwives received support mostly from their colleagues in case of a traumatic birth.

CONCLUSION(S)

Midwives need to feel valued and be supported by their institutions in coping with emotional stress. Therefore, performing clinical inspections by experienced or specialist midwives may serve as a supporting framework for reducing defensive interventions.

Core outcome set for studies on pregnant women with vasa previa (COVasP): a study protocol

INTRODUCTION

Vasa previa is a condition where fetal blood vessels run unprotected in the membranes, outside the umbilical cord, and cross the internal opening of the cervix. During rupture of membranes, these vessels can rupture and put the baby at serious risk of severe blood loss and death. Numerous studies are being conducted to improve diagnostic modalities and establish clear management plans to improve pregnancy outcomes. However, the lack of a standardised set of outcomes for studies on vasa previa makes it difficult to compare study findings and draw meaningful conclusions. Through this project, we will be developing a core outcome set for studies on pregnant women with vasa previa (COVasP).

METHODS AND ANALYSIS

The development of COVasP will involve five steps. The first will be a systematic review, in which we will generate a long list of outcomes based on published studies in pregnancies complicated with vasa previa. The second will involve in-depth interviews with current and former patients, their family members and healthcare providers who care for these patients. This will be followed by a two-round Delphi survey, which will aim to narrow down the long list of outcomes into those considered important by four groups of 'stakeholders': (1) patients, family members and patient advocates/representatives, (2) healthcare providers, (3) researchers, epidemiologists and methodologists and (4) other stakeholders directly or indirectly involved in the management of these pregnancies such as administrators, guideline developers and policymakers. The fourth step will involve a face-to-face consensus meeting using a nominal group approach to establish a finalised core outcome set. The final step will involve measuring and defining the identified outcomes using a combination of systematic reviews and Delphi surveys.

ETHICS AND DISSEMINATION

This study as well as consent forms for stakeholder participation have received approval from the Mount Sinai Hospital Research Ethics Board (REB number 18-0173-E) on 05 September 2018 and the Human Research Ethics Committee at The University of Technology Sydney, Australia on 30 July 2019 (UTS HREC reference number ETH19-3718). All progress will be documented on the international prospective register of systematic reviews and Core Outcome Measures in Effectiveness Trials databases.

Vasa previa and associated risk factors: a systematic review and meta-analysis

OBJECTIVE

To systematically review published literature and calculate the prevalence of vasa previa and its known risk factors.

MATERIALS AND METHODS

MEDLINE, Embase, the Cochrane Library, PubMed (non-MEDLINE and in process), and www.clinicaltrials.gov were searched from inception to March 2018 using indexing terms "vasa previa," "placenta previa," "low lying placenta," "succenturiate lobe," "bilobate placenta," "bilobed placenta," and "velamentous insertion." All original research studies reporting on 5 or more pregnancies with vasa previa were included. The search was limited to studies on human data and those published in the English language. Two reviewers independently screened titles and abstracts, completed data extraction, and assessed reporting quality using the Study Quality Assessment Tool for Case Series Studies of the National Heart, Lung, and Blood Institute. Disagreements were discussed and resolved at each step of the process.

RESULTS

We included 21 studies that reported 428 pregnancies with vasa previa of 1,027,918 deliveries (0.46 cases of vasa previa per 1000 deliveries). These studies fared well on risk of bias assessment using the Study Quality Assessment Tool for Case Series Studies of the National Heart, Lung, and Blood Institute. The prevalence and 95% confidence intervals of known risk factors for vasa previa included a low-lying placenta (61.5%, 53.0%-70.0%), velamentous cord insertion (52.2%, 39.6%-64.7%), bilobed or succenturiate lobed placenta (33.3%, 20.9%-45.7%), use of in vitro fertilization (26.4%, 16.0%-36.8%), and multiple gestation (8.92%, 5.33%-12.5%).

CONCLUSION

Vasa previa affects 0.46 cases per 1000 pregnancies. Given the high prevalence of prenatally detectable risk factors in affected pregnancies, the cost-effectiveness of screening strategies for vasa previa either in isolation, using a risk factor-based approach, or universally, in tandem with cervical-length screening using transvaginal ultrasound, should be revisited.

A survey of opinion and practice regarding prenatal diagnosis of vasa previa among obstetricians from Australia and New Zealand

OBJECTIVES

To define current obstetric opinion and clinical practice regarding the prenatal diagnosis of vasa previa in Australia and New Zealand.

METHODS

A population-based cross-sectional survey of Fellows of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists was conducted from April to May, 2016. Descriptive analysis was used to define factors influencing opinion and practice regarding definition of vasa previa, attributable risk factors, and the value of screening.

RESULTS

Overall, 453 respondents were included in the study. Two-thirds (304/453; 67.1%) defined vasa previa as exposed fetal vessel(s) running over or within 2 cm of the internal os. A higher proportion of ultrasound specialists (30/65; 46.2%) preferred a broader definition as compared with generalists (115/388; 29.6%; P<0.001). Overall, Fellows were supportive (342/430; 79.5%) of both reporting ultrasound-based risk factors at the 20-week anomaly scan and targeted screening (298/430; 69.3%). Only 77/453 (17.0%) respondents recognized all five "known" risk factors for vasa previa.

CONCLUSIONS

There was a lack of consensus regarding the definition and diagnosis process for vasa previa. There was also a knowledge gap in risk factors for vasa previa that would inform a targeted screening policy. Nevertheless, support for targeted screening was strong from obstetricians who responded.

Providing quality care for women with vasa praevia: Challenges and barriers faced by Australian midwives

OBJECTIVE

To explore the barriers to providing quality maternity care for women with vasa praevia as identified by Australian midwives.

DESIGN

A qualitative descriptive study using semi-structured in-depth telephone interviews.

SETTING

Australian maternity system.

METHODS

Midwives were recruited from across Australia. Interviews were audio-recorded, transcribed verbatim, and analysed using thematic analysis.

PARTICIPANTS

Twenty midwives from five Australian states practising in 15 different public or private hospitals who had cared for at least one woman with vasa praevia during 2010-2016 were interviewed. More than half of the participants held senior positions. Twelve were involved in a neonatal death or 'near-miss' due to vasa praevia.

FINDINGS

Two categories and five themes were identified in relation to barriers to the provision of quality care. Practitioner-level barriers included two themes: identifying lack of midwifery education and lack of knowledge. System-level barriers included lack of a local policy to guide practice, limited information for women, and paucity of research about vasa praevia.

CONCLUSION

Midwives experienced a number of barriers in caring for women with vasa praevia. Offering more comprehensive pre-registration and continuing professional education to midwives, developing local protocols, and providing clear written information for women may improve the provision of quality care.

IMPLICATIONS FOR PRACTICE

Midwives have a critical role in caring for and supporting women with vasa praevia. Improving midwives' knowledge with contemporary evidence and clinical guidelines could enable them to deliver safer maternity care and improve a women's journey through this potentially catastrophic condition.
