Raspberry leaf (Rubus idaeus) use in pregnancy: a prospective observational study.

BACKGROUND: Raspberry leaf use during pregnancy in Australia is widespread. There has been little research exploring the potential beneficial or harmful effects of raspberry leaf on pregnancy, labour, and birth. More research is needed to appropriately inform childbearing women and maternity healthcare professionals on the effects of raspberry leaf so that women can make informed choices. METHODS: This study aimed to determine associations between raspberry leaf use in pregnancy and augmentation of labour and other secondary outcomes. Data was derived from questionnaires which captured demographic information and herbal use in pregnancy. Clinical outcomes were accessed from the maternity services' clinical database. Data analysis was conducted in R via package 'brms' an implementation for Bayesian regression models. RESULTS: A total of 91 completed records were obtained, 44 exposed to raspberry leaf and 47, not exposed. A smaller proportion of women in the raspberry leaf cohort had augmentation of labour, epidural anaesthesia, instrumental births, caesarean section, and postpartum haemorrhage. A larger proportion had vaginal birth and length of all phases of labour were shorter. Under these conditions the use of raspberry leaf was strongly predictive of women not having their labours medically augmented. CONCLUSIONS: While our study demonstrated that raspberry leaf was strongly predictive of women not having their labours medically augmented, the results cannot be relied on or generalised to the wider population of pregnant women. While there were no safety concerns observed in our study, this should not be taken as evidence that raspberry leaf is safe. A randomised controlled trial is urgently needed to provide women and healthcare providers with robust evidence on which to base practice.

Parity, mode of birth, and long-term gynecological health: A follow-up study of parous and nonparous women in the Australian Longitudinal Study on Women's Health cohort.

BACKGROUND: Although gynecological health issues are common and cause considerable distress, little is known about their causes. We examined how birth history is associated with urinary incontinence (UI), severe period pain, heavy periods, and endometriosis. METHODS: We studied 7700 women in the Australian Longitudinal Study on Women's Health with an average follow-up of 10.9 years after their last birth. Surveys every third year provided information about birth history and gynecological health. Logistic regression was used to estimate how parity, mode of birth, and vaginal tears were associated with gynecological health issues. Presented results are adjusted odds ratios (OR) with 95% confidence intervals. RESULTS: UI was reported by 16%, heavy periods by 31%, severe period pain by 28%, and endometriosis by 4%. Compared with women with two children, nonparous women had less UI (OR 0.35 [0.26-0.47]) but tended to have more endometriosis (OR 1.70 [0.97-2.96]). Also, women with only one child had less UI (OR 0.77 [0.61-0.98]), but more severe period pain (OR 1.24 [1.01-1.51]). Women with 4+ children had more heavy periods (OR 1.42 [1.07-1.88]). Compared with women with vaginal birth(s) only, women with only cesarean sections or vaginal birth after cesarean section had less UI (ORs 0.44 [0.34-0.58] and 0.55 [0.40-0.76]), but more endometriosis (ORs 1.91 [1.16-3.16] and 2.31 [1.25-4.28]) and heavy periods (ORs 1.21 [1.00-1.46] and 1.35 [1.06-1.72]). Vaginal tear(s) did not increase UI after accounting for parity and birth mode. CONCLUSION: While women with vaginal childbirth(s) reported more urinary incontinence, they had less menstrual complaints and endometriosis.

Is carbon monoxide testing in pregnancy an acceptable and effective smoking cessation initiative? An integrative systematic review of evidence.

PROBLEM: Over 25000 Australian women smoke during pregnancy each year, with risks to mother and baby including miscarriage, pre-eclampsia, placental issues, premature birth, and stillbirth. BACKGROUND: Carbon Monoxide testing has been introduced in antenatal care settings to help identify smokers and motivate them to quit. AIM: This integrative systematic review aims to take a holistic look at Carbon Monoxide (CO) testing to understand how effective and acceptable this practice is in antenatal care. METHODS: PubMed, Scopus and CINAHL were searched for literature relating to pregnant women where CO testing has been used to identify smoking as part of a smoking cessation initiative. The search results were then screened and reviewed independently by two authors. A total of 15 studies were deemed relevant and proceeded to quality appraisal using the Crowe Critical Appraisal Tool. A Narrative Synthesis method was used to present the findings. DISCUSSION: Synthesis resulted in four themes: smoking identification and referral to cessation support, smoking cessation, midwifery usability of CO testing and women's perception of CO testing. Whilst carbon monoxide testing increased the identification and referral to cessation support for pregnant smokers, it did not make an overall difference to smoking cessation rates. Midwives frequently report having too little time to conduct carbon monoxide testing. Findings suggest that women accept the test, but their opinions are under-represented in the existing evidence. Midwives and women report concern for the midwife/woman relationship if testing is not conducted well. CONCLUSION: Whilst carbon monoxide testing can identify smoking, it does not appear to motivate pregnant smokers to quit.

Heatwaves and wildfires suffocate our healthy start to life: time to assess impact and take action.

Adverse environmental exposures in utero and early childhood are known to programme long-term health. Climate change, by contributing to severe heatwaves, wildfires, and other natural disasters, is plausibly associated with adverse pregnancy outcomes and an increase in the future burden of chronic diseases in both mothers and their babies. In this Personal View, we highlight the limitations of existing evidence, specifically on the effects of severe heatwave and wildfire events, and compounding syndemic events such as the COVID-19 pandemic, on the short-term and long-term physical and mental health of pregnant women and their babies, taking into account the interactions with individual and community vulnerabilities. We highlight a need for an international, interdisciplinary collaborative effort to systematically study the effects of severe climate-related environmental crises on maternal and child health. This will enable informed changes to public health policy and clinical practice necessary to safeguard the health and wellbeing of current and future generations.

Parity and mode of birth and their relationships with quality of life: A longitudinal study.

OBJECTIVE: To examine how (a) parity and (b) mode of birth were associated with later Quality of Life (QOL) in young adult women, with a mean follow-up of 11.0 years. DESIGN: Prospective cohort study. SETTING: Australia. R SAMPLE: A total of 7770 women participating in the 1973-1978 cohort of the Longitudinal Study of Women's Health. METHODS: Linear regression models were used to estimate (1) prospective associations between parity and mode of birth with eight subscale and two summary scores of the SF36, assessed after a mean follow-up of 11 years., and (2) differences between SF36 scores at follow up for women in different parity and mode of birth categories. MAIN OUTCOME MEASURE: Quality of Life as measured by the SF36. RESULTS: Women experiencing no births (parity 0) and one birth (parity 1) had lower scores on all the physical health measures, and on some mental health measures, than women who had 2 births (parity 2) (all p<0.05). CONCLUSIONS: Parity and mode of birth may have long-term implications for women's physical and mental health. Both childless and women with only one child had poorer physical and mental health than their peers with two children. Women with only caesarean section(s) also had poorer health than women who had vaginal birth/s.

Birth Outcomes, Health, and Health Care Needs of Childbearing Women following Wildfire Disasters: An Integrative, State-of-the-Science Review.

BACKGROUND: The frequency and severity of extreme weather events such as wildfires are expected to increase due to climate change. Childbearing women, that is, women who are pregnant, soon to be pregnant, or have recently given birth, may be particularly vulnerable to the effect of wildfire exposure. OBJECTIVES: This review sought to systematically assess what is known about birth outcomes, health, and health care needs of childbearing women during and after exposure to wildfires. METHODS: An integrative review methodology was utilized to enable article selection, data extraction, and synthesis across qualitative and quantitative studies. Comprehensive searches of SCOPUS (including MEDLINE and Embase), CINAHL, PubMed, and Google Scholar identified studies for inclusion with no date restriction. Included studies were independently appraised by two reviewers using the Crowe Critical Appraisal Tool. The findings are summarized and illustrated in tables. RESULTS: Database searches identified 480 records. Following title, abstract, and full text screening, sixteen studies published between 2012 and 2022 were identified for this review. Eleven studies considered an association between in utero exposure to wildfire and impacts on birth weight and length of gestation. One study reported increased rates of maternal gestational diabetes mellitus and gestational hypertension following exposure; whereas one study reported differences in the secondary sex ratio. Two studies reported higher incidence of birth defects following in utero exposure to wildfire smoke. Three studies reported increased mental health morbidity, and one study associated a reduction in breastfeeding among women who evacuated from a wildfire disaster. DISCUSSION: Evidence indicates that wildfire exposure may be associated with changes to birth outcomes and increased morbidity for childbearing women and their babies. These effects may be profound and have long-term and wide-ranging public health implications. This research can inform the development of effective clinical and public health strategies to address the needs of childbearing women exposed to wildfire disaster. https://doi.org/10.1289/EHP10544.

Birth plans: A systematic, integrative review into their purpose, process, and impact.

BACKGROUND: The birth plan was introduced in the 1980s to facilitate communication between maternity care providers and women and increase agency for childbearing women in the face of medicalised birth. Forty years on, the birth plan is a heterogeneous document with uncertainty surrounding its purpose, process, and impact. The aim of this review was to synthesise the evidence and improve understanding of the purpose, process and impact of the birth plan on childbearing women's experiences and outcomes. METHODS: This systematic review followed the PRISMA guidelines. A comprehensive search strategy was designed and applied to electronic databases CINAHL, MEDLINE, PsychINFO, Cochrane Library, Scopus, and ClinicalTrials.gov. Articles were appraised using the Crowe Critical Appraisal Tool and a five-step integrative approach to analysis followed. FINDINGS: Eleven articles were identified, all quantitative in nature. It is clear that the general purpose of birth plans is communication, with decision making a key factor. Even though the processes of birth planning were varied, having a birth plan was associated with generally positive birth outcomes. CONCLUSIONS: Despite the heterogeneity of birth plans, birth plans were associated with positive outcomes for childbearing women when developed in collaboration with care providers. The act of collaboratively creating a birth plan may improve obstetric outcomes, aid realistic expectations, and improve satisfaction and the sense of control.

Midwifery continuity of care and vaginal birth after caesarean section: A randomised controlled trial.

PROBLEM AND BACKGROUND: Caesarean section (CS) rates in Australia and many countries worldwide are high and increasing, with elective repeat caesarean section a significant contributor. AIM: To determine whether midwifery continuity of care for women with a previous CS increases the proportion of women who plan to attempt a vaginal birth in their current pregnancy. METHODS: A randomised controlled design was undertaken. Women who met the inclusion criteria were randomised to one of two groups; the Community Midwifery Program (CMP) (continuity across the full spectrum - antenatal, intrapartum and postpartum) (n=110) and the Midwifery Antenatal Care (MAC) Program (antenatal continuity of care) (n=111) using a remote randomisation service. Analysis was undertaken on an intention to treat basis. The primary outcome measure was the rate of attempted vaginal birth after caesarean section and secondary outcomes included composite measures of maternal and neonatal wellbeing. FINDINGS: The model of care did not significantly impact planned vaginal birth at 36 weeks (CMP 66.7% vs MAC 57.3%) or success rate (CMP 27.8% vs MAC 32.7%). The rate of maternal and neonatal complications was similar between the groups. CONCLUSION: Model of care did not significantly impact the proportion of women attempting VBAC in this study. The similarity in the number of midwives seen antenatally and during labour and birth suggests that these models of care had more similarities than differences and that the model of continuity could be described as informational continuity. Future research should focus on the impact of relationship based continuity of care.

Trends and characteristics of women undergoing induction of labour in a tertiary hospital setting: A cross-sectional study.

BACKGROUND: In many well-resourced countries, rising rates of intervention are being observed during pregnancy, labour and childbirth with induction of labour (IOL) fast becoming one of the most common. In Australia, the rate of induction of labour has increased by over 30% since 2007, and today one in three women have their labours induced. We do not however have a good understanding of the contribution of specific obstetric populations to this trend. METHODS: We examine the contribution of specific obstetric populations to induction of labour over a six-year period at one tertiary maternity service, using the Nippita classification system. Average Annual Percentage Changes (AAPC) were calculated along with 95% confidence intervals and P values set at 0.05. RESULTS: The overall rate of induction of labour increased from 21.3% in 2012 to 30.9% in 2017, representing an Average Annual Percent Change of 8.1, P<0.0001 (95% CI 7-9.6). The greatest AAPC was seen in group 5 (parous, no previous caesarean section, 39-40 weeks, single cephalic), followed by group 2 (nulliparous, 39-40 weeks, single cephalic) and 1 (nulliparous, 37-38 weeks, single cephalic). CONCLUSIONS: The use of the Nippita classification system allowed for standardised comparison across timepoints, facilitating identification of the subpopulations driving changes in rates of induction of labour. Rates of induction of labour saw a year on year increase which in this maternity service, it is not being driven by post-dates pregnancies. Further work is required to understand the role of other potential contributors such as diabetes.

Development of the Woman-Centred Care Scale- Midwife Self Report (WCCS-MSR).

BACKGROUND: Woman-centred care is recognised as a fundamental construct of midwifery practice yet to date, there has been no validated tool available to measure it. This study aims to develop and test a self-report tool to measure woman-centred care in midwives. METHODS: A staged approach was used for tool development including deductive methods to generate items, testing content validity with a group of experts, and psychometrically testing the instrument with a sample drawn from the target audience. The draft 58 item tool was distributed in an online survey using professional networks in Australia and New Zealand. Testing included item analysis, principal components analysis with direct oblimin rotation and subscale analysis, and internal consistency reliability. RESULTS: In total, 319 surveys were returned. Analysis revealed five factors explaining 47.6% of variance. Items were reduced to 40. Internal consistency (.92) was high but varied across factors. Factors reflected the extent to which a midwife meets the woman's unique needs; balances the woman's needs within the context of the maternity service; ensures midwifery philosophy underpins practice; uses evidence to inform collaborative practice; and works in partnership with the woman. CONCLUSION: The Woman-Centred Care Scale-Midwife Self Report is the first step in developing a valid and reliable tool to enable midwives to self-assess their woman-centredness. Further research in alternate populations and refinement is warranted.

A Decision Aid for midwifery continuity of care: Development and pilot acceptability testing.

BACKGROUND: Many maternity services in Australia offer women a variety of models of care including midwife led models. Childbearing women, however, need to understand the differences between these models if they are to make an informed decision about their choice of care. Decision Aids (DA) help people decide when there is not a single best option and the best decision will be based upon the values of the decision maker. There is no current tool that focuses on the choice of midwife led vs other models of maternity care. AIM: This research aimed to develop, and pilot test a Decision Aid focusing on the choice between midwife led and standard models of maternity care. METHODS: The DA was developed using the International Patient Decision Aid Standards and pilot tested for acceptability with a group of clinicians who provide antenatal care in one jurisdiction in Australia. A posttest only study was conducted assessing knowledge, acceptability and decisional conflict, with a group of women of childbearing age living in the jurisdiction. FINDINGS: A DA was developed and pilot acceptability testing with 14 women and 13 clinicians of Australian Capital Territory (ACT) health demonstrated its acceptability and highlighting areas for further development. DISCUSSION: Some revisions may be needed to address issues of balance and bias toward midwife-led care identified by some recipients. CONCLUSION: Pilot acceptability testing with women and staff of ACT health provides a steppingstone to further research, development and evaluation of this DA.

Women's motivation, perception and experience of complementary and alternative medicine in pregnancy: A meta-synthesis.

BACKGROUND: complementary and Alternative Medicine use during pregnancy is popular in many countries, including Australia. There is currently little evidence to support this practice, which raises the question of women's motivation for use of these therapies and the experiences they encounter. OBJECTIVE: this study aims to explore the perceptions, motivations and experiences of pregnant women with regard to their use of Complementary and Alternative Medicine during pregnancy. METHODS: a systemic review and meta-synthesis of the available research was conducted. Five databases were explored - CINAHL Plus, Medline, PubMed, AMED and Web of Science using the search terms complementary and alternative medicine; pregnancy; and pregnant. Articles included in this meta-synthesis were screened using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses tool. FINDINGS: ten initial themes were drawn from the six studies. These ten themes were summarised by three cluster themes. The results suggest that women are using Complementary and Alternative Medicine in their pregnancy as a means of supporting their sense of self-determination, to pursue a natural and safe childbirth, and because they experience a close affiliation with the philosophical underpinnings of Complementary and Alternative Medicine as an alternative to the biomedical model. CONCLUSION: these findings are important to practitioners, policy makers, governing bodies and researchers, providing insight into the motivations for Complementary and Alternative Medicine use by women in pregnancy.

Caring for women wanting a vaginal birth after previous caesarean section: A qualitative study of the experiences of midwives and obstetricians.

PROBLEM: One of the greatest contributors to the overall caesarean section rate is elective repeat caesarean section. BACKGROUND: Decisions around mode of birth are often complex for women and influenced by the views of the doctors and midwives who care for and counsel women. Women may be more likely to choose a repeat elective caesarean section (CS) if their health care providers lack skills and confidence in supporting vaginal birth after caesarean section (VBAC). AIM: To explore the views and experiences of providers in caring for women considering VBAC, in particular the decision-making processes and the communication of risk and safety to women. METHODS: A descriptive interpretive method was utilised. Four focus groups with doctors and midwives were conducted. FINDINGS: The central themes were: 'developing trust', 'navigating the system' and 'optimising support'. The impact of past professional experiences; the critical importance of continuity of carer and positive relationships; the ability to weigh up risks versus benefits; and the language used were all important elements. The role of policy and guidelines on providing standardised care for women who had a previous CS was also highlighted. CONCLUSION: Midwives and doctors in this study were positively oriented towards assisting and supporting women to attempt a VBAC. Care providers considered that women who have experienced a prior CS need access to midwifery continuity of care with a focus on support, information-sharing and effective communication.

Birthplace as the midwife's work place: How does place of birth impact on midwives?

BACKGROUND: In, many high and middle-income countries, childbearing women have a variety of birthplaces available to them including home, birth centres and traditional labour wards. There is good evidence indicating that birthplace impacts on outcomes for women but less is known about the impact on midwives. AIM: To explore the way that birthplace impacts on midwives in Australia and the United Kingdom. METHOD: A qualitative descriptive study was undertaken. Data were gathered through focus groups conducted with midwives in Australia and in the United Kingdom who worked in publicly-funded maternity services and who provided labour and birth care in at least two different settings. FINDINGS: Five themes surfaced relating to midwifery and place including: 1. practising with the same principles; 2. creating ambience: controlling the environment; 3. workplace culture: being watched 4. Workplace culture: "busy work" versus "being with"; and 5. midwives' response to place. DISCUSSION: While midwives demonstrate a capacity to be versatile in relation to the physicality of birthplaces, workplace culture presents a challenge to their capacity to "be with" women. CONCLUSION: Given the excellent outcomes of midwifery led care, we should focus on how we can facilitate the work of midwives in all settings. This study suggests that the culture of the birthplace rather than the physicality is the highest priority.

Gestational weight change in women attending a group antenatal program aimed at addressing obesity in pregnancy in New South Wales, Australia.

INTRODUCTION: The prevalence of obesity in Australia among women of childbearing age has doubled over the past 2 decades. Obesity is associated with complications for women and their newborns during pregnancy and birth. Limiting gestational weight gain can reduce perinatal complications and postnatal weight retention, but evidence supporting interventions designed to assist obese pregnant women to manage their weight gain in pregnancy is inconclusive. The aim of this article is to describe the gestational weight change of a cohort of obese pregnant women enrolled in a group antenatal program aimed at assisting them to limit their weight gain in pregnancy to levels recommended by the US Institute of Medicine. METHODS: The program was jointly developed by 2 metropolitan maternity services in New South Wales, Australia. This is a descriptive study that presents select data for women enrolled in the program. Body mass index (BMI), prepregnancy weight, last pregnancy weight, and selected clinical outcomes were recorded for 82 obese women enrolled in the program during the evaluation period of 14 months. Data were analyzed using nonparametric tests: the chi-square and the Mann-Whitney U tests. RESULTS: Parity was associated with prepregnancy BMI, with women of higher parity having higher BMIs. Women with higher BMIs had a significantly lower gestational weight gain than women with lower BMIs. Overall, 27% of women enrolled in the program gained the recommended 5 to 9 kg, 27% gained less than this amount, and 46% gained more. DISCUSSION: Evidence supporting interventions designed to assist obese pregnant women to manage their weight gain in pregnancy is lacking. This innovative, collaborative program shows promise, as early results compare favorably with international comparisons.

"Continuity of care" experiences in midwifery education: perspectives from diverse stakeholders.

At least 20 continuity-of-care experiences are compulsory for student midwives in Australia, but little is known about this learning component. This paper presents an analysis of continuity experiences in one Region, incorporating diverse stakeholder perspectives from student midwives, maternity managers and registered midwives, with the aim of better understanding and optimizing experiences. Qualitative methods were utilized, employing mainly focus groups. Participants included 15 student midwives from the Regional University, 14 midwives and six managers, employed at the Regional referral hospital. Four themes were identified in the data; "woman-centred care", "counting the cost", "mutual benefits" and "into the future". The significant benefits of student continuity-of-care experiences were outlined by all three participant groups. Continuity experiences for student midwives facilitated the development of a woman-centred focus in the provision of maternity care. While the experience was challenging for students it was beneficial not only to them, but to registered midwives, the maternity services, and ultimately childbearing women. In order to appropriately prepare midwives for existing and future maternity services, and to continue to meet women's needs in all service delivery models, we require midwives who are well grounded in a woman-centred care philosophy and have had exposure to various care models.

Addressing obesity in pregnancy: the design and feasibility of an innovative intervention in NSW, Australia.

OBJECTIVE: Obesity amongst women of child bearing age is increasing at an unprecedented, rate throughout the Western world. This paper describes the design of an innovative, collaborative, antenatal intervention that aims to assist women to manage their weight during pregnancy and, presents aspects of the programme evaluation. DATA SOURCES/STUDY SETTING: The programme was introduced at two sites, one in South East Sydney and, the other on the Central North Coast of NSW. Data were drawn from both sites and pooled for analysis. STUDY DESIGN: This evaluation used mixed methods drawing on qualitative and quantitative data. DATA COLLECTION METHODS: Focus groups were held with staff in the antenatal clinic, who were, responsible for recruiting to the new service. Members of staff were also asked to record BMI for all women offered the service and using a simple questionnaire, record the reasons women gave for declining the new service. PRINCIPLE FINDINGS: The recruitment rate to the new service was 35% though this result should be treated with caution. Those women with a BMI of >35 were twice as likely to elect to participate in the new service as women with a BMI of less than 35. Focus groups with midwives in the antenatal clinic responsible for recruitment identified three themes impacting on recruitment to the service; 'finding the words', 'acknowledging challenges' and 'midwives' knowledge'. CONCLUSIONS: Antenatal clinic midwives were unprepared for talking to women about their weight. Increasing the confidence and skills of staff in offering service innovations to eligible women is a major challenge to be met if new models of care are to be successful in addressing overweight and obesity in pregnancy.

Testing the Birth Unit Design Spatial Evaluation Tool (BUDSET) in Australia: a pilot study.

OBJECTIVE: To pilot test the Birth Unit Design Spatial Evaluation Tool (BUDSET) in an Australian maternity care setting to determine whether such an instrument can measure the optimality of different birth settings. BACKGROUND: Optimally designed spaces to give birth are likely to influence a woman's ability to experience physiologically normal labor and birth. This is important in the current industrialized environment, where increased caesarean section rates are causing concerns. The measurement of an optimal birth space is currently impossible, because there are limited tools available. METHODS: A quantitative study was undertaken to pilot test the discriminant ability of the BUDSET in eight maternity units in New South Wales, Australia. Five auditors trained in the use of the BUDSET assessed the birth units using the BUDSET, which is based on 18 design principles and is divided into four domains (Fear Cascade, Facility, Aesthetics, and Support) with three to eight assessable items in each. Data were independently collected in eight birth units. Values for each of the domains were aggregated to provide an overall Optimality Score for each birth unit. RESULTS: A range of Optimality Scores was derived for each of the birth units (from 51 to 77 out of a possible 100 points). The BUDSET identified units with low-scoring domains. Essentially these were older units and conventional labor ward settings. CONCLUSION: The BUDSET provides a way to assess the optimality of birth units and determine which domain areas may need improvement. There is potential for improvements to existing birth spaces, and considerable improvement can be made with simple low-cost modifications. Further research is needed to validate the tool.

Developing the Birth Unit Design Spatial Evaluation Tool (BUDSET) in Australia: a qualitative study.

OBJECTIVE: To develop a tool known as the Birth Unit Design Spatial Evaluation Tool (BUDSET), to assess the optimality of birth unit design. BACKGROUND: The space provided for childbirth influences the physiology of women in labor. Optimal birth spaces are likely to enable women to have physiologically normal labor and birth. The measurement of an optimal birth space is currently impossible, because limited tools are available. Research into optimal birth unit design is also limited. METHODS: The BUDSET was developed using a qualitative study. Data collection included an extensive literature review, interviews with key informants (architects, midwife clinicians, and researchers) and an expert panel. A Pattern Language format was used to synthesize the literature and data obtained from the key informants. RESULTS: The BUDSET is based on 18 design principles and is divided into four domains (Fear Cascade; Facility; Aesthetics; Support) with three to eight assessable items in each. CONCLUSION: Birth units must be designed so that they facilitate and support the physiology of normal childbirth. The BUDSET may provide a way to assess the optimality of birth units and determine which domain areas may need to be improved.
