Experiences of antenatal care practices to reduce stillbirth: surveys of women and healthcare professionals pre-post implementation of the Safer Baby Bundle.

BACKGROUND: The Safer Baby Bundle (SBB) aimed to reduce stillbirth rates in Australia through improving pregnancy care across five elements; smoking cessation, fetal growth restriction (FGR), decreased fetal movements (DFM), side sleeping in late pregnancy and decision making around timing of birth. We assessed experiences of women and healthcare professionals (HCPs) with antenatal care practices around the five elements. METHODS: A pre-post study design using online surveys was employed to assess change in HCPs awareness, knowledge, and frequency of performing recommended practices (22 in total) and women's experiences of care received related to reducing their chance of stillbirth. Women who had received antenatal care and HCPs (midwives and doctors) at services participating in the SBB implementation program in two Australian states were invited to participate. Surveys were distributed over January to July 2020 (pre) and August to December 2022 (post). Comparison of pre-post responses was undertaken using Fisher's exact, Pearson's chi-squared or Wilcoxon rank-sum tests. RESULTS: 1,225 women (pre-1096/post-129) and 1,415 HCPs (pre-1148/post-267, ≥ 83% midwives) completed the surveys. The frequency of HCPs performing best practice 'all the time' significantly improved post-SBB implementation across all elements including providing advice to women on side sleeping (20.4-79.4%, p < 0.001) and benefits of smoking cessation (54.5-74.5%, p < 0.001), provision of DFM brochure (43.2-85.1%, p < 0.001), risk assessments for FGR (59.2-84.1%, p < 0.001) and stillbirth (44.5-73.2%, p < 0.001). Practices around smoking cessation in general showed less improvement e.g. using the 'Ask, Advise and Help' brief advice model at each visit (15.6-20.3%, p = 0.088). Post-implementation more women recalled conversations about stillbirth and risk reduction (32.2-50.4%, p < 0.001) and most HCPs reported including these conversations in their routine care (35.1-83.0%, p < 0.001). Most HCPs agreed that the SBB had become part of their routine practice (85.0%). CONCLUSIONS: Implementation of the SBB was associated with improvements in practice across all targeted elements of care in stillbirth prevention including conversations with women around stillbirth risk reduction. Further consideration is needed around strategies to increase uptake of practices that were more resistant to change such as smoking cessation support. TRIAL REGISTRATION: The Safer Baby Bundle Study was retrospectively registered on the Australian New Zealand Clinical Trials Registry database, ACTRN12619001777189, date assigned 16/12/2019.

Likelihood of primary cesarean section following induction of labor in singleton cephalic pregnancies at term, compared with expectant management: An Australian population-based, historical cohort study.

INTRODUCTION: There has been increased use of both induction of labor (IOL) and cesarean section for women with term pregnancies in many high-income countries, and a trend toward birth at earlier gestational ages. Existing evidence regarding the association between IOL and cesarean section for term pregnancies is mixed and conflicting, and little evidence is available on the differential effect at each week of gestation, stratified by parity. MATERIAL AND METHODS: To explore the association between IOL and primary cesarean section for singleton cephalic pregnancies at term, compared with two definitions of expectant management (first: at or beyond the week of gestation at birth following IOL; and secondary: only beyond the week of gestation at birth following IOL), we performed analyses of population-based historical cohort data on women who gave birth in one Australian state (Queensland), between July 1, 2012 and June 30, 2018. Women who gave birth before 37+0 or after 41+6 weeks of gestation, had stillbirths, no-labor, multiple births (twins or triplets), non-cephalic presentation at birth, a previous cesarean section, or missing data on included variables were excluded. Four sub-datasets were created for each week at birth (37-40). Unadjusted relative risk, adjusted relative risk using modified Poisson regression, and their 95% confidence intervals were calculated in each sub-dataset. Analyses were stratified by parity (nulliparas vs. parous women with a previous vaginal birth). Sensitivity analyses were conducted by limiting to women with low-risk pregnancies. RESULTS: A total of 239 094 women were included in the analysis, 36.7% of whom gave birth following IOL. The likelihood of primary cesarean section following IOL in a Queensland population-based cohort was significantly higher at 38 and 39 weeks, compared with expectant management up to 41+6 weeks, for both nulliparas and paras with singleton cephalic pregnancies, regardless of risk status of pregnancy and definition of expectant management. No significant difference was found for nulliparas at 37 and 40 weeks; and for paras at 40 weeks. CONCLUSIONS: Future studies are suggested to investigate further the association between IOL and other maternal and neonatal outcomes at each week of gestation in different maternal populations, before making any recommendation.

Biallellic variants in CACNA1S cause fetal akinesia sequence, progressive hydrops and stillbirth.

Fetal arthrogryposis is a well-recognised ultrasonographic phenotype, caused by both genetic, maternal and extrinsic factors. When present with fetal growth restriction, pulmonary hypoplasia and multiple joint contractures, it is often referred to as fetal akinesia deformation sequence (FADS). Historically, elucidating genetic causes of arthryogryposis/FADS has been challenging; there are now more than 150 genes known to cause arthrogryposis through myopathic, neuromuscular and metabolic pathways affecting fetal movement. FADS is associated with over 400 medical conditions making prenatal diagnosis challenging. Here we present a case of FADS diagnosed at 19 weeks gestation with progression to severe fetal hydrops and stillbirth at 26-weeks gestation. Initial investigations including combined first trimester screening, TORCH (infection) screen and chromosomal microarray were normal. Trio whole exome sequencing (WES) detected compound heterozygous likely pathogenic CACNA1S gene variants associated with autosomal dominant (AD) and autosomal recessive (AR) congenital myopathy and FADS. To our knowledge, this is the first prenatal diagnosis of this condition.
