RÉSUMÉ

BACKGROUND: Women seeking a vaginal birth after a caesarean section (VBAC) frequently want to keep their subsequent labour and birth free from intervention. Water immersion (WI) during labour is potentially an effective tool for women having a VBAC for its natural pain-relieving properties. However, negotiating access to WI can be difficult, especially in the context of VBAC. AIM: To explore women's experiences of negotiating WI for labour and birth in the context of VBAC. METHODOLOGY: This Grounded Theory study followed Strauss and Corbin's framework and analytic process. Twenty-five women planning or using WI for their VBAC labour or birth were recruited from two midwifery practices and a social media group across Australia. Participants were interviewed during pregnancy and/or postnatally. FINDINGS: 'Taking the reins', the core category explaining the women's experiences of assuming authority over their birth, comprised five categories: 'Robbed of my previous birth experience'; 'My eyes were opened'; 'Water is my tool for a successful VBAC'; 'Actioning my choices and rights for WI', and 'Empowered to take back control'. 'Wanting natural and normal' was the driving force behind women's desire to birth vaginally. Two mediating factors: Having someone in your corner and Rules for birth facilitated or hindered their birth choices, respectively. CONCLUSION: The women became active participants in their healthcare by seeking information and options to keep their birth experience natural and normal. Support from other women and advocacy in the form of continuity of midwifery care was crucial in successfully negotiating WI for their VBAC when navigating the complex health system.

RÉSUMÉ

BACKGROUND: PET imaging of 18F-fluorodeoxygucose (FDG) is used widely for tumour staging and assessment of treatment response, but the biology associated with FDG uptake is still not fully elucidated. We therefore carried out gene set enrichment analyses (GSEA) of RNA sequencing data to find KEGG pathways associated with FDG uptake in primary breast cancers. METHODS: Pre-treatment data were analysed from a window-of-opportunity study in which 30 patients underwent static and dynamic FDG-PET and tumour biopsy. Kinetic models were fitted to dynamic images, and GSEA was performed for enrichment scores reflecting Pearson and Spearman coefficients of correlations between gene expression and imaging. RESULTS: A total of 38 pathways were associated with kinetic model flux-constants or static measures of FDG uptake, all positively. The associated pathways included glycolysis/gluconeogenesis ('GLYC-GLUC') which mediates FDG uptake and was associated with model flux-constants but not with static uptake measures, and 28 pathways related to immune-response or inflammation. More pathways, 32, were associated with the flux-constant K of the simple Patlak model than with any other imaging index. Numbers of pathways categorised as being associated with individual micro-parameters of the kinetic models were substantially fewer than numbers associated with flux-constants, and lay around levels expected by chance. CONCLUSIONS: In pre-treatment images GLYC-GLUC was associated with FDG kinetic flux-constants including Patlak K, but not with static uptake measures. Immune-related pathways were associated with flux-constants and static uptake. Patlak K was associated with more pathways than were the flux-constants of more complex kinetic models. On the basis of these results Patlak analysis of dynamic FDG-PET scans is advantageous, compared to other kinetic analyses or static imaging, in studies seeking to infer tumour-to-tumour differences in biology from differences in imaging.

RÉSUMÉ

Patients treated with curative-intent lung radiotherapy are in the group at highest risk of severe complications and death from COVID-19. There is therefore an urgent need to reduce the risks associated with multiple hospital visits and their anti-cancer treatment. One recommendation is to consider alternative dose-fractionation schedules or radiotherapy techniques. This would also increase radiotherapy service capacity for operable patients with stage I-III lung cancer, who might be unable to have surgery during the pandemic. Here we identify reduced-fractionation for curative-intent radiotherapy regimes in lung cancer, from a literature search carried out between 20/03/2020 and 30/03/2020 as well as published and unpublished audits of hypofractionated regimes from UK centres. Evidence, practical considerations and limitations are discussed for early-stage NSCLC, stage III NSCLC, early-stage and locally advanced SCLC. We recommend discussion of this guidance document with other specialist lung MDT members to disseminate the potential changes to radiotherapy practices that could be made to reduce pressure on other departments such as thoracic surgery. It is also a crucial part of the consent process to ensure that the risks and benefits of undergoing cancer treatment during the COVID-19 pandemic and the uncertainties surrounding toxicity from reduced fractionation have been adequately discussed with patients. Furthermore, centres should document all deviations from standard protocols, and we urge all colleagues, where possible, to join national/international data collection initiatives (such as COVID-RT Lung) aimed at recording the impact of the COVID-19 pandemic on lung cancer treatment and outcomes.

RÉSUMÉ

BACKGROUND: Relatively little is known about the extent of trauma and birth-related fear in midwives and how this might affect practice. AIM: (1) Determine prevalence of birth related trauma and fear in midwives and associations with midwives' confidence to advise women during pregnancy of their birth options and to provide care in labour. (2) Describe midwives' experiences of birth related trauma and/or fear. METHOD: A mixed methods design. A convenience sample of midwives (n=249) completed an anonymous online survey. Descriptive and inferential statistics were used to analyse the quantitative data. Latent content analysis was used to extrapolate meaning from the 170 midwives who wrote about their experiences of personal and/or professional trauma. RESULTS: The majority of midwives (93.6%) reported professional (n=199, 85.4%) and/or personal (n=97, 41.6%) traumatic birth experiences. Eight percent (n=20) reported being highly fearful of birth. Trauma was not associated with practice concerns but fear was. Midwives categorised as having 'high fear' reported more practice concerns (Med 23.5, n=20) than midwives with 'low fear' (Med 8, n=212) (U=1396, z=-3.79, p<0.001, r=0.24). Reasons for personal trauma included experiencing assault, intervention and stillbirth. Professional trauma related to both witnessing and experiencing disrespectful care and subsequently feeling complicit in the provision of poor care. Feeling unsupported in the workplace and fearing litigation intensified trauma. CONCLUSION: High fear was associated with lower confidence to support childbearing women. Fear and trauma in midwives warrants further investigation to better understand the impact on professional practice.

RÉSUMÉ

PURPOSE: The heart receives high radiation doses during radiation therapy of advanced-stage lung cancer. We have explored associations between overall survival, cardiac radiation doses, and electrocardiographic (ECG) changes in patients treated in IDEAL-CRT, a trial of isotoxically escalated concurrent chemoradiation delivering tumor doses of 63 to 73 Gy. METHODS AND MATERIALS: Dosimetric and survival data were analyzed for 78 patients. The whole heart, pericardium, AV node, and walls of left and right atria (LA/RA-Wall) and ventricles (LV/RV-Wall) were outlined on radiation therapy planning scans, and differential dose-volume histograms (dDVHs) were calculated. For each structure, dDVHs were approximated using the average dDVH and the 10 highest-ranked structure-specific principal components (PCs). ECGs at baseline and 6 months after radiation therapy were analyzed for 53 patients, dichotomizing patients according to presence or absence of "any ECG change" (conduction or ischemic/pericarditis-like change). All-cause death rate (DR) was analyzed from the start of treatment using Cox regression. RESULTS: 38% of patients had ECG changes at 6 months. On univariable analysis, higher scores for LA-Wall-PC6, Heart-PC6, "any ECG change," and larger planning target volume (PTV) were significantly associated with higher DR (P=.003, .009, .029, and .037, respectively). Heart-PC6 and LA-Wall-PC6 represent larger volumes of whole heart and left atrial wall receiving 63 to 69 Gy. Cardiac doses ≥63 Gy were concentrated in the LA-Wall, and consequently Heart-PC6 was highly correlated with LA-Wall-PC6. "Any ECG change," LA-Wall-PC6 scores, and PTV size were retained in the multivariable model. CONCLUSIONS: We found associations between higher DR and conduction or ischemic/pericarditis-like changes on ECG at 6 months, and between higher DR and higher Heart-PC6 or LA-Wall-PC6 scores, which are closely related to heart or left atrial wall volumes receiving 63 to 69 Gy in this small cohort of patients.

RÉSUMÉ

BACKGROUND: Psycho-education can reduce childbirth fear and caesarean section numbers. This study determines the cost-effectiveness of a midwife-led psycho-education intervention for women fearful of birth. METHOD: One thousand four hundred ten pregnant women in south-east Queensland, Australia were screened for childbirth fear (W-DEQ A ≥ 66). Women with high scores (n = 339) were randomised to the BELIEF Study (Birth Emotions and Looking to Improve Expectant Fear) to receive psycho-education (n = 170) at 24 and 34 weeks of pregnancy or to the control group (n = 169). Women in both groups were surveyed 6 weeks postpartum with total cost for health service use during pregnancy calculated. Logistic regression models assessed the odds ratio of having vaginal birth or caesarean section in the study groups. RESULT: Of 339 women randomised, 184 (54%) women returned data at 6 weeks postpartum (Intervention Group n = 91; Control Group n = 93). Women receiving psycho-education had a higher likelihood of vaginal birth compared to controls (n = 60, 66% vs. n = 54, 58%; OR 2.34). Mean 'treatment' cost for women receiving psycho-education was AUS$72. Mean cost for health services excluding the cost of psycho-education, was less in the intervention group (AUS$1193 vs. AUS$1236), but not significant (p = 0.78). For every five women who received midwife counselling, one caesarean section was averted. The incremental healthcare cost to prevent one caesarean section using this intervention was AUS$145. CONCLUSION: Costs of delivering midwife psycho-education to women with childbirth fear during pregnancy are offset by improved vaginal birth rates and reduction in caesarean section numbers. TRIAL REGISTRATION: Australian New Zealand Controlled Trials Registry ACTRN12612000526875 , 17th May 2012 (retrospectively registered one week after enrolment of first participant).

RÉSUMÉ

BACKGROUND: Reporting the outcomes for women and newborns accessing private midwives with visiting rights in Australia is important, especially since this data cannot currently be disaggregated from routinely collected perinatal data. AIM: 1) Evaluate the outcomes of women and newborns cared for by midwives with visiting access at one Queensland facility and 2) explore private midwives views about the structures and processes contributing to clinical outcomes. METHODS: Mixed methods. An audit of the 'all risk' 529 women receiving private midwifery care. Data were compared with national core maternity variables using Chi square statistics. Telephone interviews were conducted with six private midwives and data analysed using thematic analysis. FINDINGS: Compared to national data, women with a private midwife were significantly more likely to be having a first baby (49.5% vs 43.6% p=0.007), to commence labour spontaneously (84.7% vs 52.7%, p<0.001), experience a spontaneous vaginal birth (79% vs 54%, p<0.001) and not require pharmacological pain relief (52.9% vs 23.1%, p<0.001). The caesarean section rate was significantly lower than the national rate (13% vs 32.8%, p<0.001). In addition fewer babies required admission to the Newborn Care Unit (5.1% vs 16%, p<0.001). Midwives were proud of their achievements. Continuity of care was considered fundamental to achieving quality outcomes. Midwives valued the governance processes embedded around the model. CONCLUSIONS: Private midwives with access to the public system is safe. Ensuring national data collection accurately captures outcomes relative to model of care in both the public and private sector should be prioritised.

RÉSUMÉ

BACKGROUND: The health and wellbeing of midwives are important considerations for workforce retention and quality care. The occurrence and relationships among mental health conditions such as burnout and depression have received little attention. We investigated the prevalence of burnout, depression, anxiety and stress in Australian midwives. METHODS: An online survey was conducted in September 2014. Participants were recruited through the Australian College of Midwives and professional networks. The survey sought personal and professional details. Standard measures included the Copenhagen Burnout Inventory (CBI) (Personal, Work and Client subscales), and Depression, Anxiety, and Stress Scale (DASS). The sample was collapsed into two groups according to DASS clinical cut-offs (normal/mild versus moderate/severe/extreme). Effect size statistics were calculated and judged according to Cohen's guidelines. RESULTS: One thousand thirty-seven surveys were received. Respondents were predominantly female (98%), with an average age of 46.43 years, and 16.51 years of practice. Using a CBI subscale cut-off score of 50 and above (moderate and higher), 64.9% (n = 643) reported personal burnout; 43.8% (n = 428) reported work-related burnout; and 10.4% (n = 102) reported client-related burnout. All burnout subscales were significantly correlated with depression, anxiety and stress, particularly personal and work-related burnout with Spearman's rho correlations ranging from .51 to .63 (p < .001). Around 20% of midwives reported moderate/ severe/ extreme levels of depression (17.3%); anxiety (20.4%), and stress (22.1%) symptoms. Mann-Whitney U tests revealed significant differences between groups with depression (r = .43), anxiety (r = .41) and stress (r = 48) having a medium size effect on burnout. CONCLUSION: Prevalence of personal and work-related burnout in Australian midwives was high. The physical and psychological exhaustion associated with the different types of burnout were reflected in symptoms of depression, anxiety and stress symptoms. Further research is needed to support the personal well-being of midwives and minimize workplace burnout by developing short and long term strategies.

RÉSUMÉ

BACKGROUND: Fear of childbirth has negative consequences for a woman's physical and emotional wellbeing. The most commonly used measurement tool for childbirth fear is the Wijma Delivery Expectancy Questionnaire (WDEQ-A). Although originally conceptualized as unidimensional, subsequent investigations have suggested it is multidimensional. This study aimed to undertake a detailed psychometric assessment of the WDEQ-A; exploring the dimensionality and identifying possible subscales that may have clinical and research utility. METHODS: WDEQ-A was administered to a sample of 1410 Australian women in mid-pregnancy. The dimensionality of WDEQ-A was explored using exploratory (EFA) and confirmatory factor analysis (CFA), and Rasch analysis. RESULTS: EFA identified a four factor solution. CFA failed to support the unidimensional structure of the original WDEQ-A, but confirmed the four factor solution identified by EFA. Rasch analysis was used to refine the four subscales (Negative emotions: five items; Lack of positive emotions: five items; Social isolation: four items; Moment of birth: three items). Each WDEQ-A Revised subscale showed good fit to the Rasch model and adequate internal consistency reliability. The correlation between Negative emotions and Lack of positive emotions was strong, however Moment of birth and Social isolation showed much lower intercorrelations, suggesting they should not be added to create a total score. CONCLUSION: This study supports the findings of other investigations that suggest the WDEQ-A is multidimensional and should not be used in its original form. The WDEQ-A Revised may provide researchers with a more refined, psychometrically sound tool to explore the differential impact of aspects of childbirth fear.

RÉSUMÉ

BACKGROUND: undergraduate midwifery programmes offer opportunities for school leavers and young people (aged less than 21 years) to enter the profession. There is limited research exploring this age groups experience of their Bachelor of Midwifery programme. In order to retain these students we need to ensure that their experiences of undertaking a Bachelor of Midwifery program are positive and barriers and challenges are minimised. AIM: this study explored young midwifery students' experience of their Bachelor of Midwifery program. METHOD: a descriptive exploratory qualitative approach was used to explore the experiences of eleven students aged 20 years or less on enrolment. Data was collected using face-to-face or telephone-recorded interviews. Thematic analysis was used to analysis the data set. FINDINGS: three major themes described the young students' experiences. The first labelled 'The challenges of being young' presented a number of age related challenges including transport issues with on-call commitments as some students had not gained a driver's license. Students experienced some degree of prejudice relating to their age from their older student peers and some clinical staff during placements. 'Finding your way' was the second theme and described the strategies students used to build confidence and competence both in the university and clinical environment. The young students reported a strong commitment to the profession. They demonstrated high levels of connection with women and found the continuity of care experiences invaluable to their learning. The final theme 'Making the transition from teenager to midwife' demonstrated some unique insights into how studying to become a midwife impacted upon their personal and professional growth. CONCLUSION: the young students in this study encountered some unique issues related to their age. However as they progressed through the program they developed confidence in themselves and visualised themselves as having a long midwifery career. They were strongly motivated towards providing woman-centred maternity care and considered their continuity of care experiences fundamental to them developing a strong sense of themselves as midwives. Attracting and retaining young students is essential if the profession is to realise its goal of ensuring all women have access to a known midwife.

RÉSUMÉ

BACKGROUND: The Australian national midwifery education standards require students to complete a number of continuity of care (COC) experiences. There is increasing evidence outlining the value of this experience to the student, but there is limited research examining women's experiences of having a COC midwifery student. This study aimed to investigates the woman's experiences. METHODS: A retrospective descriptive cohort design was used. A paper-based survey was posted to all women cared for by a midwifery student in 2013 (n=698). Descriptive statistics were used to explore the proportion, mean score, standard deviation and range of the variables. Construct validity of the Satisfaction and Respect Scales was tested using exploratory factor analysis. Free text responses were analysed using latent content analysis. RESULT: One-third of women returned a completed survey (n=237/698, 34%). There was a significant positive correlation (p<0.05) between the number of AN/PN visits a midwifery student attended and women's levels of satisfaction. Women were very satisfied with having a student midwife provide continuity. The qualitative data provided additional insight demonstrating that most women had a positive relationship with the midwifery student that enhanced their childbearing experience. CONCLUSION: The women in this study valued continuity of midwifery care and were able to form meaningful relationships with their midwifery student. Programs leading to registration as a midwife should privilege continuity of care experiences. Not only does this benefit women but provides the future midwifery workforce with a clear understanding of models that best meet women's individual and the benefits of working in these models.

RÉSUMÉ

BACKGROUND: Within the context of an ageing health workforce it is important to gain a greater understanding of the motivations of young people (aged less than 21 years) to choose a career in midwifery. AIM: To explore the reasons why young students decided to study midwifery and enrol in one Australian Bachelor of Midwifery program. METHOD: A descriptive exploratory qualitative design was used. Eleven midwifery students aged less than 21 years on enrollment participated in a semi-structured tape-recorded interview. The transcribed interviews were analysed using thematic analysis. FINDINGS: Direct and indirect exposure to positive constructions of childbirth as well as the midwives role fuelled young student's fascination with midwifery and drove their desire to enrol. While some young students entered midwifery studies as a result of their 'love of babies' others took a more pragmatic 'wait and see' approach about their career choice. Many young students however clearly distinguished midwifery from nursing demonstrating an intention to be a midwife rather than a nurse. This decision often took place within the context of opposition from within their family, school and social networks where the public discourse continued to reinforce nursing as the preferred pathway to midwifery. CONCLUSION: Creating opportunities for young people to be exposed to positive constructions of childbirth as well as midwifery role models may increase the number of young students entering midwifery. There is also a need for information to be provided to school careers officers to assist them to understand the distinction between midwifery and nursing.

RÉSUMÉ

BACKGROUND: There is a growing body of evidence to show that the birth environment can influence women's experiences of labour and birth as well as midwifery practice. A common feature of the modern birth space is the bed. Knowledge about how the use of the bed shapes clinicians' perceptions and attitudes is limited. AIM: The aim of this paper is to describe midwives' perceptions of the birth bed. METHOD: Qualitative descriptive design. Fourteen midwives from one Queensland maternity unit participated in digitally recorded and transcribed interviews. Thematic analysis was used to analyse the data set. FINDINGS: Four themes were identified. The first, described beliefs that using the bed formed part of women's childbirth expectations. A second theme, captured midwives' perceptions that the bed was also an object required to safely undertake their work. The third theme described how others commonly worked to ensure the woman stayed off the bed. Lastly, there was evidence that whilst wanting to avoid the use of the bed, some were reluctant, fearing potential reprimand. CONCLUSION: The themes highlight differences in how the midwives conceptualised the use of a bed within a birth space. While some avoided the use of the bed altogether others would only conceive of women moving off the bed if everything was 'normal'. How the bed was culturally constructed appeared to dictate clinical practice. Reflecting on the meaning of an object, such as the bed, is important if clinicians are to fully understand how the birth environment influences their practice and thus women's experiences of labour and birth.

RÉSUMÉ

BACKGROUND: The WDEQ-A is the most widely used measure of childbirth fear in pregnant women; however there is increasing discussion in the literature that simpler, more culturally transferrable tools may offer a better solution to identifying fearful women in clinical practice. AIM: To compare the two item Fear of Birth Scale (FOBS) with the 33 item WDEQ-A in a large cohort of Australian pregnant women. METHOD: Self-report questionnaires during second trimester including Wijma Delivery Expectancy Questionnaire (WDEQ-A) and Fear of Birth Scale (FOBS). Correlation of FOBS and WDEQ-A was tested using Spearman's correlation coefficients. Receiver operating characteristic (ROC) curve assessed the sensitivity and specificity of possible cut-points on the FOBS against WDEQ-A cut-point of ≥85. Sensitivity, specificity, positive and negative predictive values were determined. Fearful and non-fearful women as classified by both instruments were compared for differences in demographic, psycho-social and obstetric characteristics. RESULTS: 1410 women participated. The correlation between the instruments was strong (Spearman's Rho = 0.66, p < 0.001). The area under the ROC was 0.89 indicating high sensitivity with a FOBS cut-point of 54. Sensitivity was 89%, specificity 79% and Youden index 0.68. Positive predictive value was 85% and negative predictive value 79%. Both instruments identified high fear as significantly associated with first time mothers, previous emergency caesarean and women with self-reported anxiety and/or depression. Additionally FOBS identified a significant association between fearful women and preference for caesarean. CONCLUSION: This study supports the use of the FOBS in clinical practice to identify childbirth fear in pregnant women.

RÉSUMÉ

OBJECTIVE: to assess the psychometric properties of the Perceptions of Empowerment in Midwifery Scale (PEMS) on a sample of New Zealand midwives. DESIGN: cross sectional study. Midwives completed an online survey containing the 22 item PEMS, and a number of demographic and work-related questions. PARTICIPANTS: active practising members listed on the New Zealand College of Midwives database were invited to participate. A sample of midwives who were currently employed by an organisation was extracted (n=600). FINDINGS: exploratory factor analysis on the PEMS identified four subscales (Autonomy/Empowerment, Manager Support, Professional Support, Skills and Resources). This structure differed from that reported by the original scale developers. Each subscale showed adequate internal consistency reliability and was able to distinguish midwives who had considered leaving the profession in the past six months (p=.001). KEY CONCLUSIONS: the psychometric properties of the revised 19-item four-subscale structure of PEMS were supported. IMPLICATIONS FOR PRACTICE: The PEMS-Revised provides a psychometrically sound tool for further quantitative research to supplement the growing number of qualitative investigations of midwives perceptions and experiences of their workplace.

RÉSUMÉ

Standard commercial diode detectors over-respond within small radiation fields, an effect largely attributable to the relatively high mass-density of silicon. However, Monte Carlo studies can be used to optimise dosimeter designs and have demonstrated that 'mass-density compensation'-for example, introducing a low-density air-gap upstream of a diode's high-density silicon volume-can substantially improve instrument response. In this work we used egs_chamber Monte Carlo simulations to predict the ideal air-gap thickness for a PTW 60017 unshielded diode detector. We then developed a prototype instrument incorporating that air-gap and, for a 6 MV linac, tested it experimentally against EBT3 film. We also tested a further three prototypes with different air-gap thicknesses. Our results demonstrate that for a 10 × 10 cm(2) reference field the DiodeAir, a PTW 60017 diode with a built-in air-gap of 1 mm, has on-axis correction factors near unity. Laterally the DiodeAir performs very well off-axis and reports FWHM and penumbra values consistent with those measured using EBT3. For PDD measurement, the performance of the DiodeAir matches that of the original PTW 60017. The experimental focus of this work was 6 MV but we also simulated the on-axis response of the DiodeAir within 15 MV beams and found that our modification proved robust to this substantial increase in beam energy. However, the original diode 60017 does exhibit low energy scatter dependencies and may over-respond to high linac dose-rates such that applying the mass-density compensation method to an alternative instrument (particularly a diamond detector) could ultimately take us even closer to the small-field ideal.

RÉSUMÉ

This cohort study compared 262 women with high childbirth distress to 138 non-distressed women. At 12 months, high distress women had lower health-related quality of life compared to non-distressed women (EuroQol five-dimensional (EQ-5D) scale 0.90 vs. 0.93, p = 0.008), more visits to general practitioners (3.5 vs. 2.6, p = 0.002) and utilized more additional services (e.g. maternal health clinics), with no differences for infants. Childbirth distress has lasting adverse health effects for mothers and increases health-care utilization.

RÉSUMÉ

BACKGROUND: around 20% of women suffer childbirth fear causing them significant distress and often leading to requests for caesarean section. In Sweden, fearful pregnant women are offered counselling; however, in Australia, no dedicated service caters for the specific needs of these women. Indeed scant research has been conducted in Australia and little is known about women's concerns and if these align to those reported in the international literature. AIM: to describe the sources, responses and moderators of childbirth fear in a group of pregnant women assessed as having high levels of childbirth fear. METHOD: comparative analysis was used to identify common concepts and generate themes that represented women's perspectives of childbirth fear. Data consisted of 43 tape recorded telephone conversations with highly fearful pregnant women who were participating in a large randomised controlled trial known as BELIEF (Birth Emotions, Looking to Improve Expectant Fear). FINDINGS: women's fears were conceptualised into three themes: fear stimuli; fear responses; and fear moderators. Lack of confidence to birth, fear of the unknown, internalising other women's negative stories, perineal tearing and labour pain were common concerns for first time mothers. For multiparous women, not having had personal feelings resolved following their previous birth and negative experiences of last birth influenced current expectations for their upcoming birth. Themes common to both groups were: unmet information and support needs, feelings of loss of control and lack of input in to decision-making. Some women however, chose to avoid birth planning in order to cope during pregnancy. CONCLUSION: Australian women had similar childbirth concerns to those reported in the international literature. However unique to this study was finding two opposing discourses; one of preoccupation with negative events and the other; avoidance of planning for labour and birth. Provision of woman centred maternity models that minimise obstetric intervention, offer personalised conversations following birth, and are sensitive to identifying; listening and assisting women to modify their fears in early pregnancy are required to promote positive anticipation and preparation for birth.

RÉSUMÉ

OBJECTIVE: to develop greater understanding of how expectant fathers experience their partner's labour and the subsequent birth of their baby. DESIGN: a qualitative meta-synthesis. Data were search for in CINAHL, PubMed, Psych Info and SCOPUS. SETTING: eight studies conducted in England, Malawi, Nepal and Sweden were included. PARTICIPANTS: 120 fathers with experiences of their partner having a spontaneous vaginal, assisted or surgical birth. MEASUREMENTS AND FINDINGS: 1st order themes were identified and subsequently grouped into seven 2nd order themes. Finally through a process of exploring patterns and connections seven 3rd order themes were developed which produced new insights into the men's experiences of labour and birth. This meta-synthesis revealed that most men wanted to be actively involved in their partner's labour, present at the birth and respected for what they could contribute. Men recognised that birth was a unique event that may be potentially challenging requiring a level of preparation. There were also men who felt pressured to attend. During the actual experience of labour men commonly expressed overwhelming feelings and inadequacy in their ability to support their partner. They particularly struggled with the 'pain' of labour. Midwives were subsequently identified as best placed to make a significant difference to how men perceived their experiences of labour and what they described as the life changing event of birth. KEY CONCLUSIONS: the expectant fathers' birth experiences were multidimensional. Many were committed to being involved during labour and birth but often felt vulnerable. Being prepared and receiving support were essential elements of positive experience as well as contributing to their ability to adequately support the labouring woman. IMPLICATIONS FOR PRACTICE: men's ability to actively prepare for, and be supported through, the labour and birth process influences their perceptions of the childbirth event as well as their sense of connection to their partner. Couples should be given opportunities to explore expectations and how these may influence their own construction of their role during the birth process. While the role of expectant fathers in labour and birth should be facilitated and supported arguably their wish not to participate should be afforded the same respect.
