Improving the capacity of researchers and bereaved parents to co-design and translate stillbirth research together.

BACKGROUND: Working with bereaved parents in co-designed stillbirth research, policy and practice is essential to improving care and outcomes. PROBLEM: Effective parent engagement is often lacking. This may be due to bereaved parents not feeling adequately and appropriately supported to be involved. AIM: To consult bereaved parents with the aim to understand their experiences, attitudes, and needs around involvement in stillbirth research and gain feedback about the usefulness and appropriateness of a proposed co-designed guide to support their involvement, including content and design aspects of this resource. METHODS: An online co-designed survey was disseminated via Australian parent support organisations social media in August 2022. FINDINGS: All 90 respondents were bereaved parents, 94% (n = 85) were female. Two-thirds (67%, n = 60) had never participated in stillbirth research, 80% (n = 72) agreed involvement of bereaved parents in research was important or extremely important and 81% (n = 73) were interested in future research involvement. Common motivations for involvement were wanting to leave a legacy for their baby and knowing research outcomes. Common barriers included not having been asked to participate or not knowing how. Most (89%, n = 80) agreed the proposed guide would be useful. Highly valued topics were the importance of bereaved parents' voices in stillbirth research and how they can make a difference. CONCLUSION: The majority of bereaved parents we surveyed want to be involved in stillbirth research and would value a resource to support this. The proposed concept and content for a co-designed guide to aid engagement was well supported.

Neonatal near-miss audits: a systematic review and a call to action.

BACKGROUND: Neonatal near-miss (NNM) can be considered as an end of a spectrum that includes stillbirths and neonatal deaths. Clinical audits of NNM might reduce perinatal adverse outcomes. The aim of this review is to evaluate the effectiveness of NNM audits for reducing perinatal mortality and morbidity and explore related contextual factors. METHODS: PubMed, Embase, Scopus, CINAHL, LILACS and SciELO were searched in February/2023. Randomized and observational studies of NNM clinical audits were included without restrictions on setting, publication date or language. PRIMARY OUTCOMES: perinatal mortality, morbidity and NNM. SECONDARY OUTCOMES: factors contributing to NNM and measures of quality of care. Study characteristics, methodological quality and outcome were extracted and assessed by two independent reviewers. Narrative synthesis was performed. RESULTS: Of 3081 titles and abstracts screened, 36 articles had full-text review. Two studies identified, rated, and classified contributing care factors and generated recommendations to improve the quality of care. No study reported the primary outcomes for the review (change in perinatal mortality, morbidity and NNM rates resulting from an audit process), thus precluding meta-analysis. Three studies were multidisciplinary NNM audits and were assessed for additional contextual factors. CONCLUSION: There was little data available to determine the effectiveness of clinical audits of NNM. While trials randomised at patient level to test our research question would be difficult or unethical for both NNM and perinatal death audits, other strategies such as large, well-designed before-and-after studies within services or comparisons between services could contribute evidence. This review supports a Call to Action for NNM audits. Adoption of formal audit methodology, standardised NNM definitions, evaluation of parent's engagement and measurement of the effectiveness of quality improvement cycles for improving outcomes are needed.

Australian women's perceptions and practice of sleep position in late pregnancy: An online survey.

BACKGROUND: Going-to-sleep in the supine position in later pregnancy (≥28 weeks) has been identified as a risk factor for stillbirth. Internationally, public awareness campaigns have been undertaken encouraging women to sleep on their side during late pregnancy. AIM: This study aimed to identify sleep practices, attitudes and knowledge in pregnant women, to inform an Australian safe sleeping campaign. METHODS: A web-based survey of pregnant women ≥28 weeks' gestation conducted from November 2017 to January 2018. The survey was adapted from international sleep surveys and disseminated via pregnancy websites and social media platforms. FINDINGS: Three hundred and fifty-two women participated. Five (1.6%) reported going to sleep in the supine position. Most (87.8%) had received information on the importance of side-sleeping in pregnancy. Information was received from a variety of sources including maternity care providers (186; 66.2%) and the internet (177; 63.0%). Women were more likely to report going to sleep on their side if they had received advice to do so (OR 2.3; 95% CI 1.0-5.1). Thirteen (10.8%) reported receiving unsafe advice, including changing their going-to-sleep position to the supine position. DISCUSSION: This indicates high level awareness and practice of safe late-pregnancy going-to-sleep position in participants. Opportunities remain for improvement in the information provided, and understanding needs of specific groups including Aboriginal and Torres Strait Islander women. CONCLUSION: Findings suggest Australian women understand the importance of sleeping position in late pregnancy. Inconsistencies in information provided remain and may be addressed through public awareness campaigns targeting women and their care providers.

My Baby's Movements: a stepped-wedge cluster-randomised controlled trial of a fetal movement awareness intervention to reduce stillbirths.

OBJECTIVE: The My Baby's Movements (MBM) trial aimed to evaluate the impact on stillbirth rates of a multifaceted awareness package (the MBM intervention). DESIGN: Stepped-wedge cluster-randomised controlled trial. SETTING: Twenty-seven maternity hospitals in Australia and New Zealand. POPULATION: Women with a singleton pregnancy without major fetal anomaly at ≥28 weeks of gestation from August 2016 to May 2019. METHODS: The MBM intervention was implemented at randomly assigned time points, with the sequential introduction of eight groups of between three and five hospitals at 4-monthly intervals. Using generalised linear mixed models, the stillbirth rate was compared in the control and the intervention periods, adjusting for calendar time, study population characteristics and hospital effects. MAIN OUTCOME MEASURES: Stillbirth at ≥28 weeks of gestation. RESULTS: There were 304 850 births with 290 105 births meeting the inclusion criteria: 150 053 in the control and 140 052 in the intervention periods. The stillbirth rate was lower (although not statistically significantly so) during the intervention compared with the control period (2.2/1000 versus 2.4/1000 births; aOR 1.18, 95% CI 0.93-1.50; P = 0.18). The decrease in stillbirth rate was greater across calendar time: 2.7/1000 in the first versus 2.0/1000 in the last 18 months. No increase in secondary outcomes, including obstetric intervention or adverse neonatal outcome, was evident. CONCLUSIONS: The MBM intervention did not reduce stillbirths beyond the downward trend over time. As a result of low uptake, the role of the intervention remains unclear, although the downward trend across time suggests some benefit in lowering the stillbirth rate. In this study setting, an awareness of the importance of fetal movements may have reached pregnant women and clinicians prior to the implementation of the intervention. TWEETABLE ABSTRACT: The My Baby's Movements intervention to raise awareness of decreased fetal movement did not significantly reduce stillbirth rates.

Parent engagement in perinatal mortality reviews: an online survey of clinicians from six high-income countries.

OBJECTIVE: Parent engagement in perinatal mortality review meetings following stillbirth may benefit parents and improve patient safety. We investigated perinatal mortality review meeting practices, including the extent of parent engagement, based on self-reports from healthcare professionals from maternity care facilities in six high-income countries. DESIGN: Cross-sectional online survey. SETTING: Australia, Canada, Ireland, New Zealand, UK and USA. POPULATION: A total of 1104 healthcare professionals, comprising mainly obstetricians, gynaecologists, midwives and nurses. METHODS: Data were drawn from responses to a survey covering stillbirth-related topics. Open- and closed-items that focused on 'Data quality on causes of stillbirth' were analysed. MAIN OUTCOME MEASURES: Healthcare professionals' self-reported practices around perinatal mortality review meetings following stillbirth. RESULTS: Most clinicians (81.0%) were aware of regular audit meetings to review stillbirth at their maternity facility, although this was true for only 35.5% of US respondents. For the 854 respondents whose facility held regular meetings, less than a third (31.1%) reported some form of parent engagement, and this was usually in the form of one-way post-meeting feedback. Across all six countries, only 17.1% of respondents described an explicit approach where parents provided input, received feedback and were represented at meetings. CONCLUSIONS: We found no established practice of involving parents in the perinatal mortality review process in six high-income countries. Parent engagement may hold the key to important lessons for stillbirth prevention and care. Further understanding of approaches, barriers and enablers is warranted. TWEETABLE ABSTRACT: Parent engagement in mortality review after stillbirth is rare, based on data from six countries. We need to understand the barriers.

Implementation and evaluation of a quality improvement initiative to reduce late gestation stillbirths in Australia: Safer Baby Bundle study protocol.

BACKGROUND: In 2015, the stillbirth rate after 28 weeks (late gestation) in Australia was 35% higher than countries with the lowest rates globally. Reductions in late gestation stillbirth rates have steadily improved in Australia. However, to amplify and sustain reductions, more needs to be done to reduce practice variation and address sub-optimal care. Implementing bundles for maternity care improvement in the UK have been associated with a 20% reduction in stillbirth rates. A similar approach is underway in Australia; the Safer Baby Bundle (SBB) with five elements: 1) supporting women to stop smoking in pregnancy, 2) improving detection and management of fetal growth restriction, 3) raising awareness and improving care for women with decreased fetal movements, 4) improving awareness of maternal safe going-to-sleep position in late pregnancy, 5) improving decision making about the timing of birth for women with risk factors for stillbirth. METHODS: This is a mixed-methods study of maternity services across three Australian states; Queensland, Victoria and New South Wales. The study includes evaluation of 'targeted' implementer sites (combined total approximately 113,000 births annually, 50% of births in these states) and monitoring of key outcomes state-wide across all maternity services. Progressive implementation over 2.5 years, managed by state Departments of Health, commenced from mid-2019. This study will determine the impact of implementing the SBB on maternity services and perinatal outcomes, specifically for reducing late gestation stillbirth. Comprehensive process, impact, and outcome evaluations will be conducted using routinely collected perinatal data, pre- and post- implementation surveys, clinical audits, focus group discussions and interviews. Evaluations explore the views and experiences of clinicians embedding the SBB into routine practice as well as women's experience with care and the acceptability of the initiative. DISCUSSION: This protocol describes the evaluation of the SBB initiative and will provide evidence for the value of a systematic, but pragmatic, approach to strategies to reduce the evidence-practice gaps across maternity services. We hypothesise successful implementation and uptake across three Australian states (amplified nationally) will be effective in reducing late gestation stillbirths to that of the best performing countries globally, equating to at least 150 lives saved annually. TRIAL REGISTRATION: The Safer Baby Bundle Study was retrospectively registered on the ACTRN12619001777189 database, date assigned 16/12/2019.

Survey of Australian maternity hospitals to inform development and implementation of a stillbirth prevention 'bundle of care'.

BACKGROUND: 'Bundles of care' are being implemented to improve key practice gaps in perinatal care. As part of our development of a stillbirth prevention bundle, we consulted with Australian maternity care providers. OBJECTIVE: To gain the insights of Australian maternity care providers to inform the development and implementation of a bundle of care for stillbirth prevention. METHODS: A 2018 on-line survey of hospitals providing maternity services included 55 questions incorporating multiple choice, Likert items and open text. A senior clinician at each site completed the survey. The survey asked questions about practices related to fetal growth restriction, decreased fetal movements, smoking cessation, intrapartum fetal monitoring, maternal sleep position and perinatal mortality audit. The objectives were to assess which elements of care were most valued; best practice frequency; and, barriers and enablers to implementation. RESULTS: 227 hospitals were invited with 83 (37%) responding. All proposed elements were perceived as important. Hospitals were least likely to follow best practice recommendations "all the time" for smoking cessation support (<50%), risk assessment for fetal growth restriction (<40%) and advice on sleep position (<20%). Time constraints, absence of clear guidelines and lack of continuity of carer were recognised as barriers to implementation across care practices. CONCLUSIONS: Areas for practice improvement were evident. All elements of care were valued, with increasing awareness of safe sleeping position perceived as less important. There is strong support from maternity care providers across Australia for a bundle of care to reduce stillbirth.

Induction of labour using prostaglandin E2 as an inpatient versus balloon catheter as an outpatient: a multicentre randomised controlled trial.

OBJECTIVE: To compare clinical outcomes following induction of labour (IOL) using a balloon catheter and going home, versus prostaglandin (PG) as an inpatient. DESIGN: Randomised controlled trial. SETTING: Eight Australian maternity hospitals. POPULATION: Women with uncomplicated term singleton pregnancies undergoing IOL for low-risk indications including post-term, advanced maternal age and 'social' reasons. METHODS: Between September 2015 and October 2018, 347 women were randomised to a balloon outpatient group and 348 to a PG inpatient group. The PG group received Dinoprostone, either 2 mg gel or 10 mg controlled-release tape. The balloon group had a double-balloon catheter inserted and went home. MAIN OUTCOME MEASURES: The primary outcome was a composite neonatal measure comprising nursery admission, intubation/cardiac compressions, acidaemia, hypoxic ischaemic encephalopathy, seizure, infection, pulmonary hypertension, stillbirth or death. Clinical and process outcomes are reported. RESULTS: There were no statistically significant differences in the primary outcome comparing balloon with PG (18.6% versus 25.8%; relative risk = 0.77, 95% CI 0.51-1.02; P = 0.070), cord arterial pH <7.10 (3.5% versus 9.2%; P = 0.072), nursery admissions (12.6% versus 15.5%; P = 0.379), neonatal antibiotic use (12.1% versus 17.6%; P = 0.103), or mode of birth. Nulliparous women in the balloon group had lower rates of the primary outcome (20.4% versus 31.0%;P = 0.032); Parous women were less likely to have an unassisted vaginal birth (77.6% versus 92.3%; P = 0.045). CONCLUSIONS: Balloon catheters may be a superior method of cervical priming for nulliparous women, whereas this may not be the case for parous women. It is feasible that nulliparous women go home after commencing balloon catheter IOL, and the likelihood of adverse outcomes is low. TWEETABLE ABSTRACT: Multicentre trial shows outpatient induction using balloon catheter is safe and feasible for nulliparous women.

My Baby's Movements: a stepped wedge cluster randomised controlled trial to raise maternal awareness of fetal movements during pregnancy study protocol.

BACKGROUND: Stillbirth is a devastating pregnancy outcome that has a profound and lasting impact on women and families. Globally, there are over 2.6 million stillbirths annually and progress in reducing these deaths has been slow. Maternal perception of decreased fetal movements (DFM) is strongly associated with stillbirth. However, maternal awareness of DFM and clinical management of women reporting DFM is often suboptimal. The My Baby's Movements trial aims to evaluate an intervention package for maternity services including a mobile phone application for women and clinician education (MBM intervention) in reducing late gestation stillbirth rates. METHODS/DESIGN: This is a stepped wedge cluster randomised controlled trial with sequential introduction of the MBM intervention to 8 groups of 3-5 hospitals at four-monthly intervals over 3 years. The target population is women with a singleton pregnancy, without lethal fetal abnormality, attending for antenatal care and clinicians providing maternity care at 26 maternity services in Australia and New Zealand. The primary outcome is stillbirth from 28 weeks' gestation. Secondary outcomes address: a) neonatal morbidity and mortality; b) maternal psychosocial outcomes and health-seeking behaviour; c) health services utilisation; d) women's and clinicians' knowledge of fetal movements; and e) cost. 256,700 births (average of 3170 per hospital) will detect a 30% reduction in stillbirth rates from 3/1000 births to 2/1000 births, assuming a significance level of 5%. Analysis will utilise generalised linear mixed models. DISCUSSION: Maternal perception of DFM is a marker of an at-risk pregnancy and commonly precedes a stillbirth. MBM offers a simple, inexpensive resource to reduce the number of stillborn babies, and families suffering the distressing consequences of such a loss. This large pragmatic trial will provide evidence on benefits and potential harms of raising awareness of DFM using a mobile phone app. TRIAL REGISTRATION: ACTRN12614000291684. Registered 19 March 2014. VERSION: Protocol Version 6.1, February 2018.

Parents' and healthcare professionals' experiences of care after stillbirth in low- and middle-income countries: a systematic review and meta-summary.

BACKGROUND: Stillbirth has a profound impact on women, families, and healthcare workers. The burden is highest in low- and middle-income countries (LMICs). There is need for respectful and supportive care for women, partners, and families after bereavement. OBJECTIVE: To perform a qualitative meta-summary of parents' and healthcare professionals' experiences of care after stillbirth in LMICs. SEARCH STRATEGY: Search terms were formulated by identifying all synonyms, thesaurus terms, and variations for stillbirth. Databases searched were AMED, EMBASE, MEDLINE, PsychINFO, BNI, CINAHL. SELECTION CRITERIA: Qualitative, quantitative, and mixed method studies that addressed parents' or healthcare professionals' experience of care after stillbirth in LMICs. DATA COLLECTION AND ANALYSIS: Studies were screened, and data extracted in duplicate. Data were analysed using the Sandelowski meta-summary technique that calculates frequency and intensity effect sizes (FES/IES). MAIN RESULTS: In all, 118 full texts were screened, and 34 studies from 17 countries were included. FES range was 15-68%. Most studies had IES 1.5-4.5. Women experience a broad range of manifestations of grief following stillbirth, which may not be recognised by healthcare workers or in their communities. Lack of recognition exacerbates negative experiences of stigmatisation, blame, devaluation, and loss of social status. Adequately developed health systems, with trained and supported staff, are best equipped to provide the support and information that women want after stillbirth. CONCLUSIONS: Basic interventions could have an immediate impact on the experiences of women and their families after stillbirth. Examples include public education to reduce stigma, promoting the respectful maternity care agenda, and investigating stillbirth appropriately. TWEETABLE ABSTRACT: Reducing stigma, promoting respectful care and investigating stillbirth have a positive impact after stillbirth for women and families in LMICs.

Making stillbirths visible: a systematic review of globally reported causes of stillbirth.

BACKGROUND: Stillbirth is a global health problem. The World Health Organization (WHO) application of the International Classification of Diseases for perinatal mortality (ICD-PM) aims to improve data on stillbirth to enable prevention. OBJECTIVES: To identify globally reported causes of stillbirth, classification systems, and alignment with the ICD-PM. SEARCH STRATEGY: We searched CINAHL, EMBASE, Medline, Global Health, and Pubmed from 2009 to 2016. SELECTION CRITERIA: Reports of stillbirth causes in unselective cohorts. DATA COLLECTION AND ANALYSIS: Pooled estimates of causes were derived for country representative reports. Systems and causes were assessed for alignment with the ICD-PM. Data are presented by income setting (low, middle, and high income countries; LIC, MIC, HIC). MAIN RESULTS: Eighty-five reports from 50 countries (489 089 stillbirths) were included. The most frequent categories were Unexplained, Antepartum haemorrhage, and Other (all settings); Infection and Hypoxic peripartum (LIC), and Placental (MIC, HIC). Overall report quality was low. Only one classification system fully aligned with ICD-PM. All stillbirth causes mapped to ICD-PM. In a subset from HIC, mapping obscured major causes. CONCLUSIONS: There is a paucity of quality information on causes of stillbirth globally. Improving investigation of stillbirths and standardisation of audit and classification is urgently needed and should be achievable in all well-resourced settings. Implementation of the WHO Perinatal Mortality Audit and Review guide is needed, particularly across high burden settings. FUNDING: HR, SH, SHL, and AW were supported by an NHMRC-CRE grant (APP1116640). VF was funded by an NHMRC-CDF (APP1123611). TWEETABLE ABSTRACT: Urgent need to improve data on causes of stillbirths across all settings to meet global targets. PLAIN LANGUAGE SUMMARY: Background and methods Nearly three million babies are stillborn every year. These deaths have deep and long-lasting effects on parents, healthcare providers, and the society. One of the major challenges to preventing stillbirths is the lack of information about why they happen. In this study, we collected reports on the causes of stillbirth from high-, middle-, and low-income countries to: (1) Understand the causes of stillbirth, and (2) Understand how to improve reporting of stillbirths. Findings We found 85 reports from 50 different countries. The information available from the reports was inconsistent and often of poor quality, so it was hard to get a clear picture about what are the causes of stillbirth across the world. Many different definitions of stillbirth were used. There was also wide variation in what investigations of the mother and baby were undertaken to identify the cause of stillbirth. Stillbirths in all income settings (low-, middle-, and high-income countries) were most frequently reported as Unexplained, Other, and Haemorrhage (bleeding). Unexplained and Other are not helpful in understanding why a baby was stillborn. In low-income countries, stillbirths were often attributed to Infection and Complications during labour and birth. In middle- and high-income countries, stillbirths were often reported as Placental complications. Limitations We may have missed some reports as searches were carried out in English only. The available reports were of poor quality. Implications Many countries, particularly those where the majority of stillbirths occur, do not report any information about these deaths. Where there are reports, the quality is often poor. It is important to improve the investigation and reporting of stillbirth using a standardised system so that policy makers and healthcare workers can develop effective stillbirth prevention programs. All stillbirths should be investigated and reported in line with the World Health Organization standards.

Care in subsequent pregnancies following stillbirth: an international survey of parents.

OBJECTIVE: To assess the frequency of additional care, and parents' perceptions of quality, respectful care, in pregnancies subsequent to stillbirth. DESIGN: Multi-language web-based survey. SETTING: International. POPULATION: A total of 2716 parents, from 40 high- and middle-income countries. METHODS: Data were obtained from a broader survey of parents' experiences following stillbirth. Data were analysed using descriptive statistics and stratified by geographic region. Subgroup analyses explored variation in additional care by gestational age at index stillbirth. MAIN OUTCOME MEASURES: Frequency of additional care, and perceptions of quality, respectful care. RESULTS: The majority (66%) of parents conceived their subsequent pregnancy within 1 year of stillbirth. Additional antenatal care visits and ultrasound scans were provided for 67% and 70% of all parents, respectively, although there was wide variation across geographic regions. Care addressing psychosocial needs was less frequently provided, such as additional visits to a bereavement counsellor (10%) and access to named care provider's phone number (27%). Compared with parents whose stillbirth occurred at ≤ 29 weeks of gestation, parents whose stillbirth occurred at ≥ 30 weeks of gestation were more likely to receive various forms of additional care, particularly the option for early delivery after 37 weeks. Around half (47-63%) of all parents felt that elements of quality, respectful care were consistently applied, such as spending enough time with parents and involving parents in decision-making. CONCLUSIONS: Greater attention is required to providing thoughtful, empathic and collaborative care in all pregnancies following stillbirth. Specific education and training for health professionals is needed. TWEETABLE ABSTRACT: More support for providing quality care in pregnancies after stillbirth is needed. PLAIN LANGUAGE SUMMARY: Study rationale and design More than two million babies are stillborn every year. Most parents will conceive again soon after having a stillborn baby. These parents are more likely to have another stillborn baby in the next pregnancy than parents who have not had a stillborn baby before. The next pregnancy after stillbirth is often an extremely anxious time for parents, as they worry about whether their baby will survive. In this study we asked 2716 parents from 40 countries about the care they received during their first pregnancy after stillbirth. Parents were recruited mainly through the International Stillbirth Alliance and completed on online survey that was available in six languages. Findings Parents often had extra antenatal visits and extra ultrasound scans in the next pregnancy, but they rarely had extra emotional support. Also, many parents felt their care providers did not always listen to them and spend enough time with them, involve them in decisions, and take their concerns seriously. Parents were more likely to receive various forms of extra care in the next pregnancy if their baby had died later in pregnancy compared to earlier in pregnancy. Limitations In this study we only have information from parents who were able and willing to complete an online survey. Most of the parents were involved in charity and support groups and most parents lived in developed countries. We do not know how well the findings relate to other parents. Finally, our study does not include parents who may have tried for another pregnancy but were not able to conceive. Potential impact This study can help to improve care through the development of best practice guidelines for pregnancies following stillbirth. The results suggest that parents need better emotional support in these pregnancies, and more opportunities to participate actively in decisions about care. Extra support should be available no matter how far along in pregnancy the previous stillborn baby died.

Perinatal mortality disparities between public care and private obstetrician-led care: a propensity score analysis.

OBJECTIVE: To examine whether disparities in stillbirth, and neonatal and perinatal mortality rates, between public and private hospitals are the result of differences in population characteristics and/or clinical practices. DESIGN: Retrospective cohort study. SETTING: A metropolitan tertiary centre encompassing public and private hospitals. Women accessed care from either a private obstetrician or from public models of care - predominantly midwife-led care or care shared between midwives, general practitioners, and obstetricians. POPULATION: A total of 131 436 births during 1998-2013: 69 037 public and 62 399 private. METHODS: Propensity score matching was used to select equal-sized public and private cohorts with similar characteristics. Logistic regression analysis was then used to explore the impact of public-private differences in the use of assisted reproductive technologies, plurality, major congenital anomalies, birth method, and gestational age. MAIN OUTCOME MEASURES: Stillbirth, and neonatal and perinatal mortality rates. RESULTS: After controlling for maternal and pregnancy factors, perinatal mortality rates were higher in the public than in the private cohort (adjusted odds ratio, aOR 1.53; 95% confidence interval, 95% CI 1.29-1.80; stillbirth aOR 1.56, 95% CI 1.26-1.94; neonatal death aOR 1.48, 95% CI 1.15-1.89). These disparities reduced by 15.7, 20.5, and 19.6%, respectively, after adjusting for major congenital anomalies, birth method, and gestational age. CONCLUSIONS: Perinatal mortality occurred more often among public than private births, and this disparity was not explained by population differences. Differences in clinical practices seem to be partly responsible. The impact of differences in clinical practices on maternal and neonatal morbidity was not examined. Further research is required. TWEETABLE ABSTRACT: Private obstetrician-led care: more obstetric intervention and earlier births reduce perinatal mortality. PLAIN LANGUAGE SUMMARY: Background Babies born in Australian public hospitals tend to die more often than those born in private hospitals. Our aim was to determine whether this pattern is a result of public-private differences in care or merely linked with differences in the characteristics of the two groups. In Australian private hospitals, a private obstetrician almost always provides continuing care to each woman during pregnancy and birth. Public hospitals provide a number of care options, which usually involve midwives and/or a family doctor. Method The study population included 131 436 births (52.5% public; 47.5% private) from 1998-2013 at a single metropolitan centre with co-located public and private facilities. To isolate the effect of differences in care, we used a statistical technique called propensity score matching to select a public group and a private group with similar characteristics and equal size. This enabled us to compare 'apples with apples' when comparing public versus private perinatal death rates. Perinatal deaths include stillbirths and babies that die within 28 days of birth. Main findings After matching and after accounting for different patterns in the use of fertility treatments and multiple-birth pregnancies (such as twins), babies born in the public sector were approximately 1.5 times more likely to die than babies born in the private sector. This difference was reduced to 1.3 times more likely to die than babies born in the private sector after taking into account other factors that could skew the data, such as major congenital anomalies, birth method, and duration of pregnancy. Limitations This was a single-centre study, so the results may not apply to all settings. Despite our efforts to create highly similar public and private cohorts, some differences between the groups are likely to have remained and this may have affected the results. Implications Our findings suggest that private obstetrician-led care has a beneficial impact on perinatal deaths, despite, or possibly because of, higher obstetric intervention rates and earlier births in the private hospital. Further research is required.

The WHO application of ICD-10 to deaths during the perinatal period (ICD-PM): results from pilot database testing in South Africa and United Kingdom.

OBJECTIVE: To apply the World Health Organization (WHO) Application of the International Classification of Diseases, tenth revision (ICD-10) to deaths during the perinatal period: ICD-Perinatal Mortality (ICD-PM) to existing perinatal death databases. DESIGN: Retrospective application of ICD-PM. SETTING: South Africa, UK. POPULATION: Perinatal death databases. METHODS: Deaths were grouped according to timing of death and then by the ICD-PM cause of death. The main maternal condition at the time of perinatal death was assigned to each case. MAIN OUTCOME MEASURES: Causes of perinatal mortality, associated maternal conditions. RESULTS: In South Africa 344/689 (50%) deaths occurred antepartum, 11% (n = 74) intrapartum and 39% (n = 271) in the early neonatal period. In the UK 4377/9067 (48.3%) deaths occurred antepartum, with 457 (5%) intrapartum and 4233 (46.7%) in the neonatal period. Antepartum deaths were due to unspecified causes (59%), chromosomal abnormalities (21%) or problems related to fetal growth (14%). Intrapartum deaths followed acute intrapartum events (69%); neonatal deaths followed consequences of low birthweight/ prematurity (31%), chromosomal abnormalities (26%), or unspecified causes in healthy mothers (25%). Mothers were often healthy; 53%, 38% and 45% in the antepartum, intrapartum and neonatal death groups, respectively. Where there was a maternal condition, it was most often maternal medical conditions, and complications of placenta, cord and membranes. CONCLUSIONS: The ICD-PM can be a globally applicable perinatal death classification system that emphasises the need for a focus on the mother-baby dyad as we move beyond 2015. TWEETABLE ABSTRACT: ICD-PM is a global system that classifies perinatal deaths and links them to maternal conditions.
