Midwives' support for parents following stillbirth: How they practise and resources they need from a phenomenological perspective

AIM

To explore the perceptions and experiences of midwives caring for couples who experience a stillbirth.

DESIGN

Qualitative study based on Gadamer's hermeneutic phenomenology.

METHODS

This study was conducted with midwives (n = 18) at the birth unit of a third-level public hospital in Jaén (Spain) in 2023. Personal semi-structured interviews were recorded in audio for later transcription by two researchers following steps described by Fleming.

RESULTS

Two themes were identified as important aspects of the practise of midwives in a situation of the birth of a stillborn child: (1) the importance of each action of the midwife, and (2) the availability of resources determines the care provided.

CONCLUSIONS

Having a stillbirth is a very complex experience, in which the psychological support and human and material resources involved are the basic tool for the care of these families. Acknowledging limitations of the available resources, the assistance and care provided by midwives are in line with the clinical practice guidelines, which can have an emotional impact on them.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

The care to be provided in stillbirth requires appropriate human and material resources for these families. Midwifery and nursing professionals are in a unique position for acting in cases of families with a stillbirth, updated protocols and, in general, the coordination of the different agents involved within the healthcare system. WHAT PROBLEM DID THE STUDY ADDRESS?: The midwives´ experiences in cases which end with the delivery of a stillborn. WHAT WERE THE MAIN FINDINGS?: Each action of the midwife is as important as the availability of resources to offer the most appropriate care. WHERE AND ON WHOM WILL THE RESEARCH HAVE AN IMPACT?: In each woman who receives the care of a midwife who attends the birth of a stillborn.

Retrospective Cohort Study of Syphilis-Related Stillbirths in Winnipeg, Manitoba From 2017-2020

OBJECTIVE

Syphilis-related stillbirths (SRSBs) disproportionately affect marginalized women with 11% of all local stillbirths having maternal syphilis as a contributory factor in 2020. This study describes the incidence and perinatal factors associated with SRSB.

METHODS

This was a retrospective cohort study of all stillbirths occurring from 1 January 2017 to 31 December 2020, at a single tertiary-level referral hospital in Winnipeg, Manitoba. Cases that met criteria for SRSB were identified from hospital records and included in the final analysis. Maternal demographics, comorbidities, prenatal care attendance, sexually transmitted infection testing, treatment, and diagnostic investigations at time of stillbirth were collected from hospital charts using a standardized data collection form. Descriptive statistics were performed to present the results.

RESULTS

The proportion of SRSB increased over the period of study from 0%-11%. Eleven cases were identified as SRSB, with diagnosis occurring intrapartum in 7 cases and antenatally in 4 cases. Of the 4 antenatal cases, only 2 had identifiable treatment responses indicated by microbiological and pathology workup. Commonly identified risk factors for SRSB were homelessness, mental illness, substance use, sexually transmitted co-infections, and lack of prenatal care.

CONCLUSIONS

Cases of SRSB are rising in Winnipeg with 11% of all stillbirths having maternal syphilis as a contributory factor by 2020. SRSBs disproportionately affect marginalized women. The dramatic and rapid changes in the epidemiology of syphilis in Winnipeg are likely shared by other Canadian regions and warrant increased prevention strategies to improve outcomes.

Etiology of stillbirth in a tertiary care center: a retrospective cohort study assessing ultrasound, laboratory, and pathology investigations

BACKGROUND

Canadian stillbirth data are limited, and a significant proportion of pregnancies resulting in stillbirth have no attributable cause. The objective of this study was to characterize stillbirth case investigations and management at a tertiary care hospital in Ontario, Canada.

METHODS

This was a retrospective chart review study of all cases of singleton stillbirth at The Ottawa Hospital between 1 January 2012 and 31 December 2017. Terminations and multiples stillbirths were excluded. Chart reviews were conducted to extract maternal sociodemographic, obstetrical, and fetal characteristics, including results from antenatal ultrasounds, autopsy, placenta pathology, and laboratory investigations.

RESULTS

A total of 155 eligible cases of stillbirth were identified, resulting in a 6-year stillbirth rate of 4.2 per 1000 total births. The median maternal age was 31.0 years (IQR: 29.0, 35.0) and the median gestational age at delivery was 28 weeks (IQR: 24, 35). A total of 9 (5.8%) pregnant individuals had a history of previous stillbirth. Of the 155 stillbirths, 35% underwent the full suite of post-loss laboratory, placental, and fetal autopsy investigations. 63.2% of cases had post-loss laboratory investigations completed. 76% and 71% of cases had fetal autopsy and placenta pathology evaluations completed, respectively. Antenatal characteristics associated with stillbirth included fetal anomalies/genetic markers (27.1%), umbilical cord and placental anomalies (24.5%), fetal growth abnormalities (27.7%), cervical/uterine abnormalities (11.6%), and amniotic fluid abnormalities (25.1%). The most common autopsy findings included evidence of infection (22.7%), fetal anomalies (12.6%), and fetal hypoxia (10%). The most common placental pathology findings included features of placental insufficiency (21.8%), retroplacental abnormalities (16.3%), and umbilical cord accident/infarct (15.4%).

CONCLUSIONS

Our findings demonstrate that as many as two-thirds of singleton stillbirth cases at our center did not receive the post-perinatal loss investigations recommended by clinical practice guidelines. More thorough collection of post-stillbirth data at all levels (institutional, provincial, national) is warranted to improve our understanding of stillbirth epidemiology, etiology, and management in Canada.

Maternal Hemoglobin A1c in the Third-Trimester May Underestimate Maternal Hyperglycemia and Its Impact on Offspring in Perinatal Demise Associated With Gestational Diabetes Mellitus: An Autopsy Case Series

INTRODUCTION

Gestational diabetes mellitus (GDM) is a common metabolic disorder linked to adverse pregnancy outcomes. Recent research indicates that HbA1c is reliable in detecting maternal glycemia during the first trimester but may underestimate glucose intolerance in the late second to third trimesters. Therefore, it is reasonable to hypothesize that mothers with GDM, despite apparently normal HbA1c levels in the third trimester, may give birth to infants displaying characteristic features often seen in infants of diabetic mothers with suboptimal glycemic control. This study aimed to describe a case series of autopsy cases involving stillborn or deceased neonates delivered in the third trimester to mothers diagnosed with GDM and having normal HbA1c levels at or around the time of delivery. The primary focus was on identifying and documenting the characteristic features commonly associated with "infants of diabetic mothers" with suboptimal glycemic control in this series of cases.

MATERIALS AND METHODS

We conducted a retrospective review of autopsy reports from our institution spanning 7.5 years. The study included cases that met the following criteria: (1) stillborn or infants who died in the early neonatal period, delivered in the third trimester; (2) mothers diagnosed with GDM; (3) normal maternal HbA1c levels of ≤6.1% at or around the time of delivery; (4) birthweight or femoral length exceeding the 90th percentile for gestational age; and (5) absence of genetic aberrations. We also examined these cases for other characteristic features associated with "infants of diabetic mothers."

RESULTS

Ten autopsy cases met our inclusion criteria, including 9 stillbirths and 1 neonatal death. Gestational age at delivery ranged from 32 to 39 weeks (mean: 35.7 weeks). Femoral length exceeded the 90th percentile in all cases, and 6 cases had birthweights above the 90th percentile. Puffy facies were observed in 6 cases. Among the 9 cases with complete autopsies including internal examination, 6 exhibited excess adipose tissue, 4 had cardiomegaly, and 3 showed pancreatic islet hyperplasia. Hypoxic-ischemic encephalopathy was detected in 7 cases. No structural abnormalities were noted.

DISCUSSION

Our findings demonstrated that fetuses and neonates born to mothers with apparently normal HbA1c levels in the third trimester could still display characteristic features commonly observed in infants of diabetic mothers with poor glycemic control, also known as "infants of diabetic mothers." This study underscores the potential of third-trimester maternal HbA1c measurements to underestimate maternal glycemia and its consequential impact on fetal development, as well as the subsequent manifestation of features of "infants of diabetic mothers."

Guideline No. 441: Antenatal Fetal Health Surveillance

OBJECTIVE

To summarize the current evidence and to make recommendations for antenatal fetal health surveillance (FHS) to detect perinatal risk factors and potential fetal decompensation in the antenatal period and to allow for timely intervention to prevent perinatal morbidity and/or mortality.

TARGET POPULATION

Pregnant individuals with or without maternal, fetal, or pregnancy-associated perinatal risk factors for antenatal fetal decompensation.

OPTIONS

To use basic and/or advanced antenatal testing modalities, based on risk factors for potential fetal decompensation.

OUTCOMES

Early identification of potential fetal decompensation allows for interventions that may support fetal adaptation to maintain well-being or expedite delivery.

BENEFITS, HARMS, AND COSTS

Antenatal FHS in pregnant individuals with identified perinatal risk factors may reduce the chance of adverse outcomes. Given the high false-positive rate, FHS may increase unnecessary interventions, which may result in harm, including parental anxiety, premature or operative birth, and increased use of health care resources. Optimization of surveillance protocols based on evidence-informed practice may improve perinatal outcomes and reduce harm.

EVIDENCE

Medline, PubMed, Embase, and the Cochrane Library were searched from inception to January 2022, using medical subject headings (MeSH) and key words related to pregnancy, fetal monitoring, fetal movement, stillbirth, pregnancy complications, and fetal sonography. This document represents an abstraction of the evidence rather than a methodological review.

VALIDATION METHODS

Directive clinique no 441 : Surveillance prénatale du bien-être fœtal

OBJECTIF

Résumer les données probantes actuelles et formuler des recommandations pour la surveillance prénatale du bien-être fœtal afin de détecter les facteurs de risque périnatal et toute potentielle décompensation fœtale et de permettre une intervention rapide en prévention de la morbidité et la mortalité périnatales.

POPULATION CIBLE

Personnes enceintes avec ou sans facteurs maternels, fœtaux ou gravidiques associés à des risques périnataux et à la décompensation fœtale.

OPTIONS

Utiliser des examens prénataux par technologie de base et/ou avancée en fonction des facteurs de risque de décompensation fœtale. RéSULTATS: La reconnaissance précoce de toute décompensation fœtale potentielle permet d'intervenir de façon à favoriser l'adaptation fœtale pour maintenir le bien-être ou à accélérer l'accouchement. BéNéFICES, RISQUES ET COûTS: Chez les personnes enceintes ayant des facteurs de risque périnatal confirmés, la surveillance du bien-être fœtal contribue à réduire le risque d'issue défavorable. Compte tenu du taux élevé de faux positifs, la surveillance du bien-être fœtal peut augmenter le risque d'interventions inutiles, ce qui peut avoir des effets nuisibles, dont l'anxiété parentale, l'accouchement prématuré ou assisté et l'utilisation accrue des ressources de soins de santé. L'optimisation des protocoles de surveillance d'après des pratiques fondées sur des données probantes peut améliorer les issues périnatales et réduire les effets nuisibles. DONNéES PROBANTES: Des recherches ont été effectuées dans les bases de données Medline, PubMed, Embase et Cochrane Library, de leur création jusqu'à janvier 2022, à partir de termes MeSH et de mots clés liés à la grossesse, à la surveillance fœtale, aux mouvements fœtaux, à la mortinaissance, aux complications de grossesse et à l'échographie fœtale. Le présent document est un résumé des données probantes et non pas une revue méthodologique. MéTHODES DE VALIDATION: Les auteurs ont évalué la qualité des données probantes et la force des recommandations en utilisant le cadre méthodologique GRADE (Grading of Recommendations Assessment, Development and Evaluation). Voir l'annexe A en ligne (tableau A1 pour les définitions et tableau A2 pour l'interprétation des recommandations fortes et faibles). PROFESSIONNELS CONCERNéS: Tous les membres de l'équipe de soins qui prodiguent des soins ou donnent de l'information aux patientes en obstétrique, notamment les spécialistes en médecine fœto-maternelle, les obstétriciens, les médecins de famille, les sages-femmes, les infirmières, les infirmières praticiennes et les radiologistes.

Communication and shared decision-making after stillbirth: Results of the ShaDeS study

BACKGROUND

Shared decision-making (SDM) is included in guidelines for bereavement care after a stillbirth, as it can improve women's long-term health and wellbeing. SDM within the stillbirth context is still not common, and Italy does not yet have standardised guidelines.

AIM

The ShaDeS (Shared Decision-Making in Stillbirth) study aims to investigate how Italian women with a stillbirth perceive their own centrality in decision-making processes around bereavement care and how this might impact satisfaction of care.

METHODS

The ShaDeS study is a cross-sectional study based on a web survey consisted of four sections: sociodemographic information and medical history, communication of bad news and bereavement care, decisions about childbirth (SDM-Q-9, SHARED, and DCS), and decisions and communication about autopsy (CPS).

FINDINGS

187 women answered the survey. For the 41.1% of women that did not have an emergency childbirth, the SDM-Q-9 median score was 66.6 (0-100 range), and the SHARED median score was 3.5 (1-5 range). 29.4% of participants reached the proposed cutoff of 37.5 in the DCS (0-100 range) suggesting a difficulty in reaching decisions. Satisfaction scores were lower for those with such difficulties (p < 0.0001). Of the 64.5% of women that discussed autopsy, 28.3% were involved in an SDM approach, despite this being associated with higher levels of satisfaction of care (p < 0.05).

CONCLUSION

An SDM approach is only moderately widespread amongst our participants, despite it being significantly related to higher levels of satisfaction. Further studies should investigate the tools that both patients and healthcare professionals need for an SDM approach.

Investigation and management of stillbirth: a descriptive review of major guidelines

Stillbirth is a common and devastating pregnancy complication. The aim of this study was to review and compare the recommendations of the most recently published guidelines on the investigation and management of this adverse outcome. A descriptive review of guidelines from the American College of Obstetricians and Gynecologists (ACOG), the Royal College of Obstetricians and Gynecologists (RCOG), the Perinatal Society of Australia and New Zealand (PSANZ), the Society of Obstetricians and Gynecologists of Canada (SOGC) on stillbirth was carried out. Regarding investigation, there is consensus that medical history and postmortem examination are crucial and that determining the etiology may improve care in a subsequent pregnancy. All guidelines recommend histopathological examination of the placenta, genetic analysis and microbiology of fetal and placental tissues, offering less invasive techniques when autopsy is declined and a Kleihauer test to detect large feto-maternal hemorrhage, whereas they discourage routine screening for inherited thrombophilias. RCOG and SOGC also recommend a complete blood count, coagulopathies' testing, anti-Ro and anti-La antibodies' measurement in cases of hydrops and parental karyotyping. Discrepancies exist among the reviewed guidelines on the definition of stillbirth and the usefulness of thyroid function tests and maternal viral screening. Moreover, only ACOG and RCOG discuss the management of stillbirth. They agree that, in the absence of coagulopathies, expectant management should be considered and encourage vaginal birth, but they suggest different labor induction protocols and different management in subsequent pregnancies. It is important to develop consistent international practice protocols, in order to allow effective determination of the underlying causes and optimal management of stillbirths, while identifying the gaps in the current literature may highlight the need for future research.

Exploring management of antenatally diagnosed fetal syphilis infection

BACKGROUND

The incidence of syphilis among Canadian women of childbearing age has risen dramatically in the past decade, with a resurgence of infants born with congenital syphilis. While guidelines exist to guide maternal infection during pregnancy, there is little evidence available to guide management in situations where the developing fetus is found to be severely affected.

CASE REVIEW

Our patient presented in the second trimester of her pregnancy as syphilis contact. Positive serologic tests (venereal disease research laboratory titre of 1:64) and a chancre suggested primary infection. Ultrasound demonstrated a fetus at 19+3 weeks gestation with hydrops fetalis and a markedly abnormal brain. Amniocentesis confirmed congenital syphilis infection on polymerase chain reaction testing. After nine days of intravenous penicillin G, the fetal status had worsened, and the family ultimately chose a medical termination of the pregnancy.

DISCUSSION

Evolving ultrasound technology has allowed us to identify severely affected fetuses, who may historically have been delivered stillborn. Following routine syphiliotherapy with benzathine penicillin, these abnormal ultrasound features may take weeks or months to reverse, which poses a challenge in prognostication and counselling. Case reports data suggests intensive treatment with intravenous penicillin may be effective in severe cases where fetal hydrops is present.

CONCLUSION

This case highlights the potential morbidity of fetal syphilis infection and underscores the paucity of current literature. Information sharing will be essential to build a modern knowledge base on treating this ancient disease.

When there is only one patient: Induction of labour for termination of pregnancy

Induction of labour when no live birth is anticipated presents a number of unique considerations for members of the healthcare team. The main indication for Induction of Labour for Termination of Pregnancy (iTOP) is intrauterine fetal death (IUFD) beyond a gestational age where surgical management is available, but may also be indicated in the setting of induction abortion (with or without feticide), and termination of pregnancy (with or without infant palliation) for pregnancies where a lethal fetal anomaly is diagnosed. In tertiary care centres, iTOP may represent a significant proportion of labouring patients. Despite this, there are few guidelines dedicated specifically to iTOP in either obstetrical or family planning specialties. In this article, we will consider four main themes from an evidence-informed perspective: method selection; pre-induction preparation; clinical considerations during and after iTOP; and complications management.

Sex Differences Are Here to Stay: Relevance to Prenatal Care

Sex differences exist in the incidence and presentation of many pregnancy complications, including but not limited to pregnancy loss, spontaneous preterm birth, and fetal growth restriction. Sex differences arise very early in development due to differential gene expression from the X and Y chromosomes, and later may also be influenced by the action of gonadal steroid hormones. Though offspring sex is not considered in most prenatal diagnostic or therapeutic strategies currently in use, it may be beneficial to consider sex differences and the associated mechanisms underlying pregnancy complications. This review will cover (i) the prevalence and presentation of sex differences that occur in perinatal complications, particularly with a focus on the placenta; (ii) possible mechanisms underlying the development of sex differences in placental function and pregnancy phenotypes; and (iii) knowledge gaps that should be addressed in the development of diagnostic or risk prediction tools for such complications, with an emphasis on those for which it would be important to consider sex.
