OBJECTIVE: To assess the association between maternal asthma and adverse perinatal outcomes in an Australian Indigenous population. METHODS: This prospective cohort study included all Indigenous mother and baby dyads for births from 2001 to 2013 in Western Australia (n = 25 484). Data were linked from Western Australia Births, Deaths, Midwives, Hospital, and Emergency Department collections. Maternal asthma was defined as a self-reported diagnosis at an antenatal visit or hospitalization or emergency visit for asthma during pregnancy or less than 3 years before pregnancy. Associations with birth, labor, and pregnancy outcomes were assessed using generalized estimating equations. Asthma exacerbation during pregnancy and stratification by remoteness was also assessed. RESULTS: Maternal asthma was associated with placental abruption (adjusted odds ratio [aOR], 1.59 [95% confidence interval (CI), 1.07-2.35]), threatened preterm labor (aOR, 1.58 [95% CI, 1.39-1.79]), and emergency cesarean sections (aOR, 1.27 [95% CI, 1.13-1.44]). These risks increased further with an asthma exacerbation during pregnancy or if the mother was from a remote area. No associations were found for low birth weight, preterm birth, small for gestational age, or perinatal mortality. CONCLUSION: Maternal asthma in Indigenous women is associated with an increased risk of emergency cesarean sections, placental abruption, and threatened preterm labor. These risks may be mitigated by improved management of asthma exacerbations during pregnancy.

PROBLEM: Complex physiological processes are often difficult for midwifery students to comprehend when using traditional teaching and learning approaches. Online resources for midwifery education are limited. BACKGROUND: Face to face instructional workshops using simulation have had some impact on improving understanding. However, in the 21st century new technologies offer the opportunity to provide alternative learning approaches. Virtual and artificial realities have been shown to increase confidence in decision making during clinical practice. AIM: Explore the impact of using three-dimensional (3D) visualisation in midwifery education, on student's application, when educating women about the birth of the placenta, and membranes. METHODS: Face to face individual interviews were performed, to collect deep, meaningful experiences of students, learning about the third stage of labour. FINDINGS: Prior clinical experiences impacted on student's ability to articulate how they would discuss birth of the placenta and membranes, and the process of haemostasis with women. DISCUSSION: The narrative findings of this pilot study identified ways that students traditionally learn midwifery, through theory, and clinical practice. Interview narratives illustrated how midwifery students who had previous experiences of witnessing birth, had superior ability to discuss the third stage of labour with women. While students with limited birth experiences, found the 3DMVR assisted them in their understanding of the physiology of the third stage of labour. CONCLUSION: In an environment of increasing technological advances, clinical placements remain an essential component of midwifery education.

BACKGROUND: With the impact of over two centuries of colonisation in Australia, First Nations families experience a disproportionate burden of adverse pregnancy and birthing outcomes. First Nations mothers are 3-5 times more likely than other mothers to experience maternal mortality; babies are 2-3 times more likely to be born preterm, low birth weight or not to survive their first year. 'Birthing on Country' incorporates a multiplicity of interpretations but conveys a resumption of maternity services in First Nations Communities with Community governance for the best start to life. Redesigned services offer women and families integrated, holistic care, including carer continuity from primary through tertiary services; services coordination and quality care including safe and supportive spaces. The overall aim of Building On Our Strengths (BOOSt) is to facilitate and assess Birthing on Country expansion into two settings - urban and rural; with scale-up to include First Nations-operated birth centres. This study will build on our team's earlier work - a Birthing on Country service established and evaluated in an urban setting, that reported significant perinatal (and organisational) benefits, including a 37% reduction in preterm births, among other improvements. METHODS: Using community-based, participatory action research, we will collaborate to develop, implement and evaluate new Birthing on Country care models. We will conduct a mixed-methods, prospective birth cohort study in two settings, comparing outcomes for women having First Nations babies with historical controls. Our analysis of feasibility, acceptability, clinical and cultural safety, effectiveness and cost, will use data including (i) women's experiences collected through longitudinal surveys (three timepoints) and yarning interviews; (ii) clinical records; (iii) staff and stakeholder views and experiences; (iv) field notes and meeting minutes; and (v) costs data. The study includes a process, impact a

The inclusion of Indigenous cultures, known as the cultural determinants of health, in healthcare policy and health professional education accreditation and registration requirements, is increasingly being recognised as imperative for improving the appalling health and well-being of Indigenous Australians. These inclusions are a strengths-based response to tackling the inequities in Indigenous Australians' health relative to the general population. However, conceptualising the cultural determinants of health in healthcare practice has its contextual challenges, and gaps in implementation evidence are apparent. In this paper, we provide a case example, namely the Katherine Hospital, of how healthcare services can implement the cultural determinants of health into clinical practice. However, to be effective, health professionals must concede that Australia's Indigenous peoples' knowledges involving cultural ways of being, knowing and doing must co-exist with western and biomedical knowledges of health practice. We use the Katherine Hospital ABC Radio National Background Briefing interview, which was mentioned by two research participants in a 2020 study, as an example of good practice that we can learn from. Additionally, the six Aboriginal and Torres Strait Islander Health actions contained in the 2nd Edition of the Australian National Safety and Quality Health Service Standards provide governance and accountability examples of how to enable Indigenous people's cultures and their knowledges in the provision of services. The role of non-Indigenous clinical allies and accomplices is imperative when embedding and enacting Indigenous Australians' cultures in service systems of health. When Indigenous Peoples access mainstream hospitals, deep self-reflection by allies and accomplices is necessary to enable safe, quality care, and treatment that is culturally safe and free from racism. Doing so can increase cultural responsiveness free of racism, thereby reducing the inher

The aim of this paper is to describe the development of a model of care to embed cultural safety for Aboriginal children into paediatric hospital settings. The Daalbirrwirr Gamambigu (pronounced “Dahl-beer-weer gum-um-be-goo” in the Gumbaynggirr language means ‘safe children’) model encompasses child protection responses at clinical, managerial and organisational levels of health services. A review of scholarly articles and grey literature followed by qualitative interviews with Aboriginal health professionals formed the evidence base for the model, which then underwent rounds of consultation for cultural suitability and clinical utility. Culturally appropriate communication with children and their families using clinical yarning and a culturally adapted version of ISBAR (a mnemonic for Identify, Situation, Background, Assessment and Recommendation) for interprofessional communication is recommended. The model guides the development of a critical consciousness about cultural safety in health care settings, and privileges the cultural voices of many diverse Aboriginal peoples. When adapted appropriately for local clinical and cultural contexts, it will contribute to a patient journey experience of respect, dignity and empowerment.

BACKGROUND: Complex physiological processes are often difficult for midwifery students to comprehend when using traditional teaching and learning approaches. Face to face instructional workshops using simulation have had some impact on improving understanding. However, in the 21st century new technologies offer the opportunity to provide alternative learning approaches. AIM: To investigate the impact of using three-dimensional (3D) visualisation in midwifery education on student's experience of learning, and retention of knowledge at three points in time. DESIGN: A pilot study involving a two-armed parallel Randomised Controlled Trial (RCT) comparing the retention of knowledge scores between the control and intervention groups. SETTING: An Australian University in the Northern Territory. PARTICIPANTS: The sample included second year Bachelor of Midwifery students (n = 38). All received traditional midwifery education before being randomly allocated to either the intervention (n = 20) or control (n = 18) group. METHODS: A new immersive virtual environment was introduced to complement existing traditional midwifery education on the third stage of labour. This intervention was evaluated using a demographic survey and multiple-choice questionnaire to collect baseline information via Qualtrics. To measure change in knowledge and comprehension, participants completed the same multiple-choice knowledge questionnaire at three time points; pre, immediately post and at 1 month post intervention. In addition, the intervention group completed a 3D student satisfaction survey. RESULTS: Baseline knowledge scores were similar between the groups. A statistically significant increase in knowledge score was evident immediately post intervention for the intervention group, however there was no significant difference in knowledge score at one month. CONCLUSIONS: The results support the creation of further three-dimensional visualisation teaching resources for midwifery education. Howev

BACKGROUND: The nutritional and health benefits of breastfeeding for infants and young children are well-established however rates of breastfeeding initiation and duration for Aboriginal and Torres Strait Islander children are lower than non-Indigenous children. AIM: To describe factors influencing breastfeeding practice amongst Aboriginal and Torres Strait Islander women. METHODS: A scoping narrative review was conducted using the Joanna Briggs Institute framework. A search was conducted in four online databases (PubMed, Scopus, ANU SuperSearch, and Science Direct). Findings were analysed using [30] narrative synthesis. FINDINGS: This review included 9 journal articles, a conference summary and a book. This review identified four factors influencing women's breastfeeding practice; sources of support, culturally appropriate care, intention to breastfeed and social determinants. CONCLUSION: Multiple social determinants resulting from colonization have interrupted traditional infant feeding practices and women's sources of support. Although Aboriginal and Torres Strait Islander women have strong intention to breastfeed, their breastfeeding outcomes are impacted by lack of pro-breastfeeding support when encountering breastfeeding challenges as well as norms surrounding the use of infant formula milk. Culturally appropriate care is essential for identifying women's needs and avoiding stereotyping. Further research is needed to investigate the effectiveness of breastfeeding interventions for this group of women.

PROBLEM/BACKGROUND: Strong international evidence demonstrates significantly improved outcomes for women and their babies when supported by midwifery continuity of care models. Despite this, widespread implementation has not been achieved, especially in regional settings. AIM: To develop a theoretical understanding of the factors that facilitate or inhibit the implementation of midwifery continuity models within regional settings. METHODS: A Constructivist Grounded Theory approach was used to collect and analyse data from 34 interviews with regional public hospital key informants. RESULTS: Three concepts of theory emerged: 'engaging the gatekeepers', 'midwives lacking confidence' and 'women rallying together'. The concepts of theory and sub-categories generated a substantive theory: A partnership between midwives and women is required to build confidence and enable the promotion of current evidence; this is essential for engaging key hospital stakeholders to invest in the implementation of midwifery continuity of care models. DISCUSSION: The findings from this research suggest that midwives and women can significantly influence the implementation of midwifery continuity models within their local maternity services, particularly in regional settings. Midwives' reluctance to transition is based on a lack of confidence and knowledge of what it is really like to work in midwifery continuity models. Similarly, women require education to increase awareness of continuity of care benefits, and a partnership between women and midwives can be a strong political force to overcome many of the barriers. CONCLUSION: Implementation of midwifery continuity of care needs a coordinated ground up approach in which midwives partner with women and promote widespread dissemination of evidence for this model, directed towards consumers, midwives, and hospital management to increase awareness of the benefits.

Australia's local, state, territory and federal governments have agreed that the 10-year life expectancy gap between Indigenous and non-Indigenous Australians will be closed by 2031. However, annual Closing the Gap reports tabled by the various prime ministers in the Australian Parliament (for the past 12 years) have consistently indicated that the life expectancy gap continues to widen. Australia has seen more than three decades of government policies since the landmark 1989 National Aboriginal health strategy. What has been missing from these policy commitments is the genuine enactment of the knowledges that are held by Indigenous Australians relating to their cultural ways of being, knowing and doing. Privileging Indigenous knowledges, cultures and voices must be front and centre in developing, designing and implementing policies and programs. The sharing of power, provision of resources, culturally informed reflective policy making, and program design are critical elements. In this paper, we provide a conceptual model of practice, working at the cultural interface where knowledges are valued and innovations can occur. This model of practice is where knowledges and cultures can co-exist, and it could be the answer to Closing the Gap in life expectancy by 2031. Despite a growing willingness and need to consider these models, there remains a deep-seated resistance to identifying and addressing institutional and systemic racism and racist attitudes, including unconscious biases held by individuals. Further, western non-Indigenous worldviews of ways of being, knowing and doing continue to dominate the decisions and actions of governments - and consequentially dominate public health policies and practices. There is an unacceptable standard approach, for and about Indigenous health instead of with Indigenous peoples, resulting in the neglectful dismissal of Indigenous knowledges and Indigenous cultures of ways of being, knowing and doing.

AbstractThe objective of this scoping review was to map the current practice and best evidence for embedding cultural safety in child protection responses for Aboriginal families in hospitals. Electronic databases were searched systematically and the reference lists examined. Efforts to reduce the risk of bias were made including using an inductive approach. Eight research papers were included following the exclusion of 25 papers for the final analysis. Three main themes in relation to what is necessary to embed cultural safety for Aboriginal families when child protection responses are raised in hospital were found. These were (a) relationships, (b) organisational processes and (c) culture. The analysis underscores the need for development of child protection strategies that focus on cultural safety rather than cultural competence alone. This provides some direction for policy and practice development in this field, and has also highlighted the deficiencies in evidence and urgent need for further research.

Issue There is an underrepresentation of Aboriginal and Torres Strait Islander midwives across Australia and an inadequate number of graduating midwives to redress this. A major pillar for the Birthing on Country Model is maternity care workforce development. Aim The purpose of this review is to examine the enablers and barriers that Aboriginal students experience while undertaking the Bachelor of Midwifery degree in Australia. Methods A search of the literature was undertaken through electronic databases. When only three papers were found looking at the experiences of Aboriginal midwifery students the search was broadened to include Aboriginal undergraduate health students. Findings The literature review reported a strong need for cultural safety in both the clinical and education systems. Students with access to cultural supports, relationships with Aboriginal mentors and academics and Aboriginal clinical placements felt empowered and were able to navigate the ‘two worlds’ in a meaningful way. Discussion This review highlights a significant gap in the literature. Despite the expanded search terms to include Aboriginal health students, a relatively narrow range of papers were found. Interestingly, the combined search revealed similar themes: kinship, personal factors, and cultural issues. Conclusion Empowering and supporting Aboriginal Peoples to become midwives is essential. While systems and societies aim for cultural safety, this review shows there is still a way to go. Further research is essential to decolonise higher education and health care systems, and provide strong, well supported pathways for Aboriginal midwifery students.

Nurses and midwives of Australia now is the time for change! As powerfully placed, Indigenous and non-Indigenous nursing and midwifery professionals, together we can ensure an effective and robust Indigenous curriculum in our nursing and midwifery schools of education. Today, Australia finds itself in a shifting tide of social change, where the voices for better and safer health care ring out loud. Voices for justice, equity and equality reverberate across our cities, our streets, homes, and institutions of learning. It is a call for new songlines of reform. The need to embed meaningful Indigenous health curricula is stronger now than it ever was for Australian nursing and midwifery. It is essential that nursing and midwifery leadership continue to build an authentic collaborative environment for Indigenous curriculum development. Bipartisan alliance is imperative for all academic staff to be confident in their teaching and learning experiences with Indigenous health syllabus. This paper is a call out. Now is the time for Indigenous and non-Indigenous nurses and midwives to make a stand together, for justice and equity in our teaching, learning, and practice. Together we will dismantle systems, policy, and practices in health that oppress.

© 2017 Australian College of Midwives Background: Women at risk of preterm birth before 32 weeks gestation are routinely transferred to facilitate birth at a hospital that has Neonatal Intensive Care. The clinical outcomes of being ‘in-born” improves newborn and neonatal outcomes is well documented. However little is known about the women's experiences when such a complication occurs. Method: Using the NSW Agency for Clinical Innovation Patient and Carer stories method, 10 women were purposively invited and consented to tell their stories. Semi-structured interviews were undertaken during their inpatient stay and then again, by telephone in the months following their baby's due date. Themes were identified, illustrated by exemplars. Results: All women were multiparous. Without exception, the women said that having the support of their family was the most important factor in coping with their unexpected hospitalisation and the anxiety of having to deal with the uncertainty of their pregnancy outcome. The most difficult aspect of their experience was the distress of being separated from their children and families and undue stress and distress from their partners. Other issues they identified were: physical difficulties during transfer; information overload as they sought to understand their changing circumstances; accommodation issues; and financial stress resulting from their relocation. Conclusions: All women perceived their midwifery, obstetric and neonatal care to be exceptional and their neonatal outcomes were positive. Improvements may be made by facilitating family contact allowing flexible visiting, assisting with partner/family accommodation, providing women with their basic needs during transport and providing assistance to relieve financial strain.

Background: In many countries midwives act as the main providers of care for women throughout pregnancy, labour and birth. In our large public teaching hospital in Australia we restructured the way midwifery care is offered and introduced caseload midwifery for one third of women booked at the hospital. We then compared the costs and birth outcomes associated with caseload midwifery compared to the two existing models of care, standard hospital care and private obstetric care.Methods: We undertook a cross sectional study examining the risk profile, birth outcomes and cost of care for women booked into one of the three available models of care in a tertiary teaching hospital in Australia between July 1st 2009 December 31st 2010. To control for differences in population or case mix we described the outcomes for a cohort of low risk first time mothers known as the 'standard primipara'.Results: Amongst the 1,379 women defined as 'standard primipara' there were significant differences in birth outcome. These first time 'low risk' mothers who received caseload care were more likely to have a spontaneous onset of labour and an unassisted vaginal birth 58.5% in MGP compared to 48.2% for Standard hospital care and 30.8% with Private obstetric care (p < 0.001). They were also significantly less likely to have an elective caesarean section 1.6% with MGP versus 5.3% with Standard care and 17.2% with private obstetric care (p < 0.001). From the public hospital perspective, over one financial year the average cost of care for the standard primipara in MGP was $3903.78 per woman. This was $1375.45 less per woman than those receiving Private obstetric care and $1590.91 less than Standard hospital care per woman (p < 0.001). Similar differences in cost were found in favour of MGP for all women in the study who received caseload care.Conclusions: Cost reduction appears to be achieved through reorganising the way care is delivered in the public hospital system with the introduction of

Australia has an enviable record of safety for women in childbirth. There is nevertheless growing concern at the increasing level of intervention and consequent morbidity amongst childbearing women. Not only do interventions impact on the cost of services, they carry with them the potential for serious morbidities for mother and infant.Models of midwifery have proliferated in an attempt to offer women less fragmented hospital care. One of these models that is gaining widespread consumer, disciplinary and political support is caseload midwifery care. Caseload midwives manage the care of approximately 35-40 a year within a small Midwifery Group Practice (usually 4-6 midwives who plan their on call and leave within the Group Practice.) We propose to compare the outcomes and costs of caseload midwifery care compared to standard or routine hospital care through a randomised controlled trial.

We propose to compare the outcomes and costs of caseload midwifery care compared to standard or routine hospital care through a randomised controlled trial.Methods/design: A two-arm RCT design will be used. Women will be recruited from tertiary women's hospitals in Sydney and Brisbane, Australia. Women allocated to the caseload intervention will receive care from a named caseload midwife within a Midwifery Group Practice. Control women will be allocated to standard or routine hospital care. Women allocated to standard care will receive their care from hospital rostered midwives, public hospital obstetric care and community based general medical practitioner care. All midwives will collaborate with obstetricians and other health professionals as necessary according to the woman's needs.Discussion: Data will be collected at recruitment, 36 weeks antenatally, six weeks and six months postpartum by web based or postal survey. With 750 women or more in each of the intervention and control arms the study is powered (based on 80% power; alpha 0.05) to detect a difference in caesarean section rates of 29.4 to 22.9%; instrumental birth rates from 11.0% to 6.8%; and rates of admission to neonatal intensive care of all neonates from 9.9

Maternity services in Australia are in urgent need of change. During the last 10 years several reviews have highlighted the need to provide more continuity of care for women in conjunction with the rationalisation of services. One solution may lie in the development of new integrated systems of care where primary-level maternity units offer midwifery-led care and women are transferred into perinatal centres to access tertiary-level obstetric technology and staff when required. This case study outlines the introduction of caseload midwifery into an Area Health Service in metropolitan Sydney. Our objective is to explore the concept of caseload midwifery and the process of implementing the first midwifery-led unit in NSW within an integrated service network. The midwife-led unit is a small but growing phenomenon in many countries. However, the provision of "continuity" and "woman-centred" midwifery care involves radical changes to conventional hospital practice.

Measurements of the U37K′ index and the absolute abundance of alkenones in marine sediments are increasingly used in paleoceanographic research as proxies of past sea surface temperature and haptophyte (mainly coccolith-bearing species) primary productivity, respectively. An important aspect of these studies is to be able to compare reliably data obtained by different laboratories from a wide variety of locations. Hence the intercomparability of data produced by the research community is essential. Here we report results from an anonymous interlaboratory comparison study involving 24 of the leading laboratories that carry out alkenone measurements worldwide. The majority of laboratories produce data that are intercomparable within the considered confidence limits. For the measurement of alkenone concentrations, however, there are systematic biases between laboratories, which might be related to the techniques employed to quantify the components. The maximum difference between any two laboratories for any two single measurements of U37K′ in sediments is estimated, with a probability of 95%, to be <2.1°C. In addition, the overall within-laboratory precision for the U37K′ temperature estimates is estimated to be <1.6°C (95% probability). Similarly, from the analyses of alkenone concentrations the interlaboratory reproducibility is estimated at 32%, and the repeatability is estimated at 24%. The former is compared to a theoretical estimate of reproducibility and found to be excessively high. Hence there is certainly scope and a demonstrable need to improve reproducibility and repeatability of U37K′ and especially alkenone quantification data across the community of scientists involved in alkenone research.
