RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Although many pregnant women accept referrals to stop-smoking support, the uptake of appointments often remains low. AIM: The aim was to review the success of interventions to increase the uptake of external stop-smoking appointments following health professional referrals in pregnancy. MATERIALS AND METHODS: Embase, PubMed, Cochrane Central Register of Controlled Trials, Scopus and CINAHL were searched in February 2023 for studies with interventions to increase the uptake rates of external stop-smoking appointments among pregnant women who smoke. Eligible studies included randomised, controlled, cluster-randomised, quasi-randomised, before-and-after, interrupted time series, case-control and cohort studies. Cochrane tools assessing for bias and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. RESULTS: Two before-and-after studies were included, including a combined total of 1996 women who smoked during pregnancy. Both studies had a serious risk of bias, and meta-analysis was not possible due to heterogeneity. One study testing carbon monoxide monitors and opt-out referrals showed increased uptake of external stop-smoking appointments, health professional referrals and smoking cessation rates compared to self-identified smoking status and opt-in referrals. Results were limited in the second study, which used carbon monoxide monitors, urinary cotinine levels and self-disclosed methods to identify the smoking status with opt-out referrals. Only post-intervention data were available on the uptake of appointments to external stop-smoking services. The number of health professional referrals increased, but change in smoking cessation rates was less clear. CONCLUSIONS: There is insufficient evidence to inform practice regarding strategies to increase the uptake of external stop-smoking appointments by women during pregnancy.

RESUMO

BACKGROUND: There is growing evidence regarding the potential of closed incision negative pressure wound therapy (ci-NPWT) to prevent surgical site infections (SSIs) in healing wounds by primary closure following a caesarean section (CS). AIM: To assess the cost-effectiveness of ci-NPWT compared to standard dressings for prevention of SSI in obese women giving birth by CS. MATERIALS AND METHODS: Cost-effectiveness and cost-utility analyses from a health service perspective were undertaken alongside a multicentre pragmatic randomised controlled trial, which recruited women with a pre-pregnancy body mass index ≥30 kg/m2 giving birth by elective/semi-urgent CS who received ci-NPWT (n = 1017) or standard dressings (n = 1018). Resource use and health-related quality of life (SF-12v2) collected during admission and for four weeks post-discharge were used to derive costs and quality-adjusted life years (QALYs). RESULTS: ci-NPWT was associated with AUD$162 (95%CI -$170 to $494) higher cost per person and an additional $12 849 (95%CI -$62 138 to $133 378) per SSI avoided. There was no detectable difference in QALYs between groups; however, there are high levels of uncertainty around both cost and QALY estimates. There is a 20% likelihood that ci-NPWT would be considered cost-effective at a willingness-to-pay threshold of $50 000 per QALY. Per protocol and complete case analyses gave similar results, suggesting that findings are robust to protocol deviators and adjustments for missing data. CONCLUSIONS: ci-NPWT for the prevention of SSI in obese women undergoing CS is unlikely to be cost-effective in terms of health service resources and is currently unjustified for routine use for this purpose.

RESUMO

BACKGROUND: Up to 20% of all stillbirths and 45% of term stillbirths are currently classified as unexplained. Many of these stillbirths do not undergo currently recommended investigations. This may leave questions unanswered and not identify stillbirths with a recurrence risk in subsequent pregnancies. AIMS: To validate a new tool (Stillbirth Investigation Utility Tool) to identify the clinical utility of investigations in stillbirth and the inter-rater agreement on cause of stillbirth using the Perinatal Society of Australia and New Zealand-Perinatal Death Classification (PSANZ-PDC). MATERIALS AND METHODS: Thirty-four stillbirths were randomly selected for inclusion, each assessed independently by five blinded assessors. The investigations were grouped into three categories: clinical and laboratory; placental pathology; and autopsy examination. The cause of death was assigned at the end of each group. Outcome measures were clinical utility of investigations measured by assessor rated usefulness and inter-rater agreement on the assigned cause of death. RESULTS: Comprehensive maternal history, maternal full blood count, maternal blood group and screen and placenta histopathology were useful in all cases. Clinical photographs were not performed and should have been performed in 50% of cases. The inter-rater agreement on cause of death assigned after all investigation results was 0.93 (95% CI 0.87-1.0). CONCLUSIONS: The new Stillbirth Investigation Utility Tool showed very good agreement in assigning the cause of death using PSANZ-PDC. Four investigations were useful in all cases. Minor refinements will be made based on feedback to enhance usability for wider implementation in research studies to assess the yield of investigations in stillbirths.

RESUMO

BACKGROUND: Delayed reporting of decreased fetal movements (DFM) could represent a missed opportunity to prevent stillbirth. Mobile phone applications (apps) have the potential to improve maternal awareness and reporting of DFM and contribute to stillbirth prevention. AIMS: To evaluate the effectiveness of the My Baby's Movements (MBM) app on late-gestation stillbirth rates. MATERIALS AND METHODS: The MBM trial evaluated a multifaceted fetal movements awareness package across 26 maternity services in Australia and New Zealand between 2016 and 2019. In this secondary analysis, generalised linear mixed models were used to compare rates of late-gestation stillbirth, obstetric interventions, and neonatal outcomes between app users and non-app users including calendar time, cluster, primiparity and other potential confounders as fixed effects, and hospital as a random effect. RESULTS: Of 140 052 women included, app users comprised 9.8% (n = 13 780). The stillbirth rate was not significantly lower among app users (1.67/1000 vs 2.29/1000) (adjusted odds ratio (aOR) 0.79; 95% CI 0.51-1.23). App users were less likely to have a preterm birth (aOR 0.81; 0.75-0.88) or a composite adverse neonatal outcome (aOR 0.87; 0.81-0.93); however, they had higher rates of induction of labour (IOL) (aOR 1.27; 1.22-1.32) and early term birth (aOR 1.08; 1.04-1.12). CONCLUSIONS: The MBM app had low uptake and its use was not associated with stillbirth rates but was associated with some neonatal benefit, and higher rates of IOL and early term birth. Use and acceptability of tools designed to promote fetal movement awareness is an important knowledge gap. The implications of increased IOL and early term births warrant consideration in future studies.

RESUMO

OBJECTIVES: The purpose of this study was to identify differences in health service expenditure on Indigenous and non-Indigenous women who experience a stillbirth, women's out-of-pocket costs, and health service use. METHODS: The project used a whole-of-population linked data set called "Maternity1000," which includes all women who gave birth in Queensland, Australia, between July 1, 2012, and June 30, 2018 (n = 396 158). Multivariable analysis was undertaken to assess differences in mean health service expenditure; and number of health care services accessed between Indigenous and non-Indigenous women who had a stillbirth from birth to twelve months postpartum. Costs are presented in 2019/20 Australian dollars. RESULTS: There was a total of 1864 babies stillborn to women in Queensland between July 1, 2012, and June 30, 2018, with 135 being born to Indigenous women and 1729 born to non-Indigenous women. There was significantly lower total expenditure per woman for Indigenous women compared with non-Indigenous women ($16 083 and $18 811, respectively). This was consistent across public hospital inpatient ($12 564 compared with $14 075), outpatient ($1127 compared with $1470), community-based services ($198 compared with $313), pharmaceuticals ($8 compared with $22), private hospital ($434 compared with $1265), and for individual out-of-pocket fees ($21 compared with $86). Mean expenditure on emergency department services per woman was higher for Indigenous women compared with non-Indigenous women ($947 compared with $643). Indigenous women who experienced a stillbirth accessed fewer general practitioners, allied health, specialist, obstetrics, and outpatient services, and fewer pathology and diagnostic test than their non-Indigenous counterparts. CONCLUSIONS: Inequities in access to health services exist between Indigenous and non-Indigenous women who experience a stillbirth.

RESUMO

BACKGROUND: Surgical site infection (SSI) after a caesarean section is of concern (CS) is of concern to both clinicians and women themselves. AIMS: The aim of this study is to identify the cumulative incidence and predictors of SSI in women who are obese and give birth by elective CS. MATERIALS AND METHODS: The method used was planned secondary analysis of data from women with a pre-pregnancy body mass index (BMI) ≥30 kg/m2 giving birth by elective CS in a multicentre randomised controlled trial of a prophylactic closed-incision negative pressure wound therapy dressing. Data were collected from medical records, direct observations of the surgical site and self-reported signs and symptoms from October 2015 to December 2019. The Centers for Disease Control and Prevention definition was used to identify SSI. Women were followed up once in hospital just before discharge and then weekly for four weeks after discharge. Blinded outcome assessors determined SSI. After the cumulative incidence of SSI was calculated, multiple variable logistic regression models were used to identify independent risk factors for SSI. RESULTS: SSI incidence in 1459 women was 8.4% (122/1459). Multiple variable-adjusted odds ratios (OR) for SSI were BMI ≥40 kg/m2 (OR 1.55, 95% confidence interval (CI) 1.30-1.86) as compared to BMI 30-34.9 0 kg/m2 , ≥2 previous pregnancies (OR 1.38, 95% CI 1.00-1.80) as compared to no previous pregnancies and pre-CS vaginal cleansing (OR 0.55, 95% CI 0.33-0.99). CONCLUSIONS: Our findings may inform preoperative counselling and shared decision-making regarding planned elective CS for women with pre-pregnancy BMI ≥30 kg/m2 .

RESUMO

To characterise the demographic and clinical characteristics of women who died by suicide in the perinatal period to inform and improve suicide prevention strategies. Retrospective analysis of maternal suicides during and within 1 year after the end of pregnancy in Queensland between January 2004 and December 2017. Outcomes measured included timing of death in relation to pregnancy, sociodemographic and clinical characteristics and health service use prior to death. There were 65 deaths by suicide in the study period; six occurred during pregnancy, 30 occurred after a live birth, 22 occurred after a termination of pregnancy and seven followed a miscarriage or stillbirth. Most suicides were late maternal deaths. Women were younger, and more likely to identify as Aboriginal or Torres Strait Islander, when compared to all women giving birth for the same time period. Most women had a prior mental health diagnosis, most commonly depression. Over half of women had recent relationship separation or conflict prior to death. Perinatal women had higher rates of death by violent means than all women in Queensland who died by suicide during the same time period. The demographic, psychosocial and clinical characteristics of a group of women who died by suicide have been described, and this shows a high proportion of women with a prior mental health diagnosis. To reduce maternal mortality, psychosocial screening must be implemented broadly and continued until the end of the first year postpartum. Similar screening attention is needed for women who had a termination of pregnancy, miscarriage or stillbirth.

RESUMO

BACKGROUND: The Safer Baby Bundle (SBB) eLearning is an online education module that addresses practice gaps in stillbirth prevention in Australia. It provides healthcare professionals with evidence-based resources for: smoking cessation; fetal growth restriction; decreased fetal movements; maternal safe going-to-sleep position; and timing of birth for women with risk factors for stillbirth. AIMS: To determine whether participants' reported knowledge and confidence in providing care designed to reduce stillbirth changed following completion of the module. To assess the module's suitability and acceptability, and participants' reported likelihood to change practice. MATERIALS AND METHODS: In-built surveys undertaken pre- and post-eLearning module assessed participant knowledge and confidence, module suitability and acceptability, and likelihood of practice change using Likert items. Responses were dichotomised. Differences pre- and post-module were tested using McNemar's test and differences by profession were examined using descriptive statistics and Pearson's χ2 test. RESULTS: Between 15 October 2019 and 2 November 2020, 5223 participants across Australia were included. Most were midwives (82.0%), followed by student midwives (4.6%) and obstetricians (3.3%). Reported knowledge and confidence improved in all areas (P < 0.001). Post-module 96.7-98.9% 'agreed' they had a sound level of knowledge and confidence across all elements of the SBB. Over 95% of participants agreed that the module was helpful and relevant, well organised, and easy to access and use. Eighty-eight percent reported they were likely to change some aspect of their clinical practice. CONCLUSIONS: The SBB eLearning module is a valuable education program that is well-received and likely to result in improvements in practice.

RESUMO

BACKGROUND: Stillbirth is a major public health problem that is slow to improve in Australia. Understanding the causes of stillbirth through appropriate investigation is the cornerstone of prevention and important for parents to understand why their baby died. AIM: The aim of this study is to assess compliance with the Perinatal Society of Australia and New Zealand (PSANZ) Perinatal Mortality Clinical Practice Guidelines (2009) for stillbirths. METHODS: This is a prospective multi-centred cohort study of stillbirths at participating hospitals (2013-2018). Data were recorded into a purpose-built database. The frequency of the recommended core investigations was calculated, and χ2 test was performed for subgroup analyses by gestational age groups and timing of fetal death. A 70% compliance threshold was defined for investigations. The cause of death categories was provided according to PSANZ Perinatal Death Classification. RESULTS: Among 697 reported total stillbirths, 562 (81%) were antepartum, and 101 (15%) were intrapartum. The most common cause of death categories were 'congenital abnormality' (12.5%), 'specific perinatal conditions' (12.2%) and 'unexplained antepartum death' (29%). According to 2009 guidelines, there were no stillbirths where all recommended investigations were performed (including or excluding autopsy). A compliance of 70% was observed for comprehensive history (82%), full blood count (94%), cytomegalovirus (71%), toxoplasmosis (70%), renal function (75%), liver function (79%), external examination (86%), post-mortem examination (84%) and placental histopathology (92%). The overall autopsy rate was 52%. CONCLUSIONS: Compliance with recommended investigations for stillbirth was suboptimal, and many stillbirths remain unexplained. Education on the value of investigations for stillbirth is needed. Future studies should focus on understanding the yield and value of investigations and service delivery gaps that impact compliance.

RESUMO

BACKGROUND: Stillbirth rates have shown little improvement for two decades in Australia. Perinatal mortality audit is key to prevention, but the literature suggests that implementation is suboptimal. AIM: To determine the proportion of perinatal deaths which are associated with contributing factors relating to care in Queensland, Australia. MATERIALS AND METHODS: Retrospective audit of perinatal deaths ≥ 34 weeks gestation by the Health Department in Queensland was undertaken. Cases and demographic information were obtained from the Queensland Perinatal Data Collection. A multidisciplinary panel used the Perinatal Society of Australia and New Zealand (PSANZ) perinatal mortality audit guidelines to classify the cause of death and to identify contributing factors. Contributing factors were classified as 'insignificant', 'possible', or 'significant'. RESULTS: From 1 January to 31 December 2018, 65 deaths (56 stillbirths and nine neonatal deaths) were eligible and audited. Most deaths were classified as unexplained (51.8% of stillbirths). Contributing factors were identified in 46 (71%) deaths: six insignificant (all stillbirths), 20 possibly related to outcome (17 stillbirths), and 20 significantly (16 stillbirths). Areas for practice improvements mainly related to the care for women with risk factors for stillbirth, especially antenatal care. The PSANZ guidelines were applied and enabled a systematic approach. CONCLUSIONS: A high proportion of late gestation perinatal deaths are associated with contributing factors relating to care. Improving antenatal care for women with risk factors for stillbirth is a priority. Perinatal mortality audit is a valuable step in stillbirth prevention and the PSANZ guidelines allow a systematic approach to aid implementation and reporting.

RESUMO

Given that aminoglycosides, such as amikacin, may be used for multidrug-resistant Pseudomonas aeruginosa infections, optimization of therapy is paramount for improved treatment outcomes. This study aims to investigate the pharmacodynamics of different simulated intravenous amikacin doses on susceptible P. aeruginosa to inform ventilator-associated pneumonia (VAP) and sepsis treatment choices. A hollow-fiber infection model with two P. aeruginosa isolates (MICs of 2 and 8 mg/liter) with an initial inoculum of ∼108 CFU/ml was used to test different amikacin dosing regimens. Three regimens (15, 25, and 50 mg/kg) were tested to simulate a blood exposure, while a 30 mg/kg regimen simulated the epithelial lining fluid (ELF) for potential respiratory tract infection. Data were described using a semimechanistic pharmacokinetic/pharmacodynamic (PK/PD) model. Whole-genome sequencing was used to identify mutations associated with resistance emergence. While bacterial density was reduced by >6 logs within the first 12 h in simulated blood exposures following this initial bacterial kill, there was amplification of a resistant subpopulation with ribosomal mutations that were likely mediating amikacin resistance. No appreciable bacterial killing occurred with subsequent doses. There was less (<5 log) bacterial killing in the simulated ELF exposure for either isolate tested. Simulation studies suggested that a dose of 30 and 50 mg/kg may provide maximal bacterial killing for bloodstream and VAP infections, respectively. Our results suggest that amikacin efficacy may be improved with the use of high-dose therapy to rapidly eliminate susceptible bacteria. Subsequent doses may have reduced efficacy given the rapid amplification of less-susceptible bacterial subpopulations with amikacin monotherapy.

RESUMO

BACKGROUND: Clinical interventions known to reduce the risk of caesarean delivery include routine induction of labour at 39 weeks, caseload midwifery and chart audit, but they have not been compared for cost-effectiveness. OBJECTIVE: To assesses the cost-effectiveness of three different interventions known to reduce caesarean delivery rates compared to standard care; and conduct a budget impact analysis. METHODS: A Markov microsimulation model was constructed to compare the costs and outcomes produced by the different interventions. Costs included all costs to the health system, and outcomes were quality-adjusted life years (QALY) gained. A budget impact analysis was undertaken using this model to quantify the costs (in Australian dollars) over three years for government health system funders. RESULTS: All interventions, plus standard care, produced similar health outcomes (mean of 1.84 QALYs gained over 105 weeks). Caseload midwifery was the lowest cost option at $15 587 (95% confidence interval [CI] 15 269, 15 905), followed by routine induction of labour ($16 257, 95% CI 15 989, 16 536), and chart audit ($16 325, 95% CI 15 979, 16 671). All produced lower costs on average than standard care ($16 905, 95% CI 16 551, 17 259). Caseload midwifery would produce the greatest savings of $172.6 million over three years if implemented for all low-risk nulliparous women in Australia. CONCLUSIONS: Caseload midwifery presents the best value for reducing caesarean delivery rates of the options considered. Routine induction of labour at 39 weeks and chart audit would also reduce costs compared to standard care.

RESUMO

BACKGROUND: Reducing stillbirth rates is an international priority; however, little is known about the cost of stillbirth. This analysis sought to quantify the costs of stillbirth in Australia. METHODS: Mothers and costs were identified by linking a state-based registry of all births between 2012 and 2015 to other administrative data sets. Costs from time of birth to 2 years postbirth were included. Propensity score matching was used to account for differences between women who had a stillbirth and those that did not. Macroeconomic costs were estimated using value of lost output analysis and value of lost welfare analysis. RESULTS: Cost to government was on average $3774 more per mother who had a stillbirth compared with mothers who had a live birth. After accounting for gestation at birth, the cost of a stillbirth was 42% more than a live birth (P < .001). Costs for inpatient services, emergency department services, services covered under Medicare (such as primary and specialist care, diagnostic tests and imaging), and prescription pharmaceuticals were all significantly higher for mothers who had a stillbirth. Mothers who had a stillbirth paid on average $1479 out of pocket, which was 52% more than mothers who had a live birth after accounting for gestation at birth (P < .001). The value of lost output was estimated to be $73.8 million (95% CI: 44.0 million-103.9 million). The estimated value of lost social welfare was estimated to be $18 billion. DISCUSSION: Stillbirth has a sustained economic impact on society and families, which demonstrates the potential resource savings that could be generated from stillbirth prevention.

RESUMO

BACKGROUND: The United States (US) spends more on health care than any other high-resource country. Despite this, their maternal and newborn outcomes are worse than all other countries with similar levels of economic development. Our purpose was to describe maternal and newborn outcomes and organization of care in four high-resource countries (Australia, Canada, the Netherlands, and United Kingdom) with consistently better outcomes and lower health care costs, and to identify opportunities for emulation and improvement in the United States. METHOD: We examined resources that described health care organization and financing, provider types, birth settings, national, clinical guidelines, health care policies, surveillance data, and information for consumers. We conducted interviews with country stakeholders representing the disciplines of obstetrics, midwifery, pediatrics, neonatology, epidemiology, sociology, political science, public health, and health services. The results of the analysis were compared and contrasted with the US maternity system. RESULTS: The four countries had lower rates of maternal mortality, low birthweight, and newborn and infant death than the United States. Five commonalities were identified as follows: (1) affordable/ accessible health care, (2) a maternity workforce that emphasized midwifery care and interprofessional collaboration, (3) respectful care and maternal autonomy, (4) evidence-based guidelines on place of birth, and (5) national data collections systems. CONCLUSIONS: The findings reveal marked differences in the other countries compared to the United States. It is critical to consider the evidence for improved maternal and newborn outcomes with different models of care and to examine US cultural and structural failures that are leading to unacceptable and substandard maternal and infant outcomes.

RESUMO

BACKGROUND: Traumatic stress can adversely affect obstetricians' mental health and may affect care provision. Little is known about the impact of traumatic birth on the Australasian obstetric workforce. AIM: To assess the feasibility of conducting a binational survey of Australia and New Zealand obstetricians, trainees, and general practitioner obstetricians, to determine the prevalence of trauma exposure and associated factors. MATERIALS AND METHODS: Feasibility was assessed using a convergent mixed-methods design. The pilot online survey assessed traumatic exposure and included the Posttraumatic Diagnostic Scale, Copenhagen Burnout Inventory (work subscale), and Posttraumatic Growth Inventory (short form). Qualitative data were generated from survey comments and telephone interviews and thematically analysed. RESULTS: Using various recruitment strategies, 32 participants completed the survey, and eight completed interviews. Most participants were consultant obstetricians. Nearly all (n = 31, 96.9%) had been exposed to traumatic birth(s). Three-quarters had current symptoms of traumatic stress, one-quarter had symptoms of work-related burnout, but over two-fifths reported significant post-traumatic growth. Thematic analysis revealed perceptions that 'obstetricians experience substantial trauma', there is a 'culture of blame in obstetrics', and only 'in some workplaces it's supportive and safe'. Feasibility issues included the need to identify the respondent's level of training at the time when their most traumatic birth occurred, ensure anonymity of responses, and use a different tool to assess traumatic stress symptoms. CONCLUSIONS: Conducting a full study of this important topic appeared feasible. Standardised measures were acceptable. Revision of some questions is required. Anonymity needs to be promoted.

RESUMO

BACKGROUND: Eclampsia is a serious consequence of pre-eclampsia. There are limited data from Australia and New Zealand (ANZ) on eclampsia. AIM: To determine the incidence, management and perinatal outcomes of women with eclampsia in ANZ. MATERIALS AND METHODS: A two-year population-based descriptive study, using the Australasian Maternity Outcomes Surveillance System (AMOSS), carried out in 263 sites in Australia, and all 24 New Zealand maternity units, during a staggered implementation over 2010-2011. Eclampsia was defined as one or more seizures during pregnancy or postpartum (up to 14 days) in any woman with clinical evidence of pre-eclampsia. RESULTS: Of 136 women with eclampsia, 111 (83%) were in Australia and 25 (17%) in New Zealand. The estimated incidence of eclampsia was 2.2 (95% confidence interval (CI) 1.9-2.7) per 10 000 women giving birth. Aboriginal and Torres Strait Islander women were over-represented in Australia (n = 9; 8.1%). Women with antepartum eclampsia (n = 58, 42.6%) were more likely to have a preterm birth (P = 0.04). Sixty-three (47.4%) women had pre-eclampsia diagnosed prior to their first eclamptic seizure of whom 19 (30.2%) received magnesium sulphate prior to the first seizure. Nearly all women (n = 128; 95.5%) received magnesium sulphate post-seizure. No woman received prophylactic aspirin during pregnancy. Five women had a cerebrovascular haemorrhage, and there were five known perinatal deaths. CONCLUSIONS: Eclampsia is an uncommon consequence of pre-eclampsia in ANZ. There is scope to reduce the incidence of this condition, associated with often catastrophic morbidity, through the use of low-dose aspirin and magnesium sulphate in women at higher risk.
