Midwifery 2024; 136:104101. [PMID: 39002394 DOI: 10.1016/j.midw.2024.104101] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 06/10/2024] [Accepted: 07/03/2024] [Indexed: 07/15/2024]
Abstract
BACKGROUND The debate on the safety and outcomes of home versus hospital births highlights the need for evidence-based evaluations of these birthing settings, particularly in Catalonia where both options are available. AIM To compare sociodemographic characteristics and maternal and neonatal outcomes between low-risk women opting for home versus hospital births in Catalonia, Spain. METHODS This observational cross-sectional study analysed 3,463 low-risk births between 2016 and 2018, including 2,713 hospital and 750 home births. Researchers collected sociodemographic data, birthing processes, and outcomes, using statistical analysis to explore differences between the settings. FINDINGS Notable differences emerged: Women choosing home births typically had higher education levels and were predominantly Spanish. They were 3.43 times more likely to have a spontaneous birth and significantly less likely to undergo instrumental births than those in hospitals. Home births were associated with higher utilization of non-pharmacological analgesia and a more pronounced tendency to iniciate breastfeeding within the first hour post birth and stronger inclination towards breastfeeding. Hospital births, conversely, showed higher use of the lithotomy position and epidural analgesia. There were no significant differences in neonatal outcomes between the two groups. CONCLUSIONS AND IMPLICATION FOR PRACTICE Home births managed by midwives offered better obstetric and neonatal outcomes for low-risk women than hospital births. These results suggest home birth as a safe, viable option that promotes natural birthing processes and reduces medical interventions. The study supports the integration of midwife-led home birth into public health policies, affirming its benefits for maternal and neonatal health.

Abstract
OBJECTIVE Investigate maternal and neonatal outcomes associated with breech presentation in planned community births in the United States, including outcomes associated with types of breech presentation (i.e., frank, complete, footling/kneeling). DESIGN Secondary analysis of prospective cohort data from a national perinatal data registry (MANA Stats). SETTING Planned community birth (homes and birth centers), United States. SAMPLE Individuals with a term, singleton gestation (N = 71,943) planning community birth at labor onset. METHODS Descriptive statistics to calculate associations between types of breech presentation and maternal and neonatal outcomes. MAIN OUTCOME MEASURES Maternal: intrapartum/postpartum transfer, hospitalization, cesarean, hemorrhage, severe perineal laceration, duration of labor stages and membrane rupture Neonatal: transfer, hospitalization, NICU admission, congenital anomalies, umbilical cord prolapse, birth injury, intrapartum/neonatal death. RESULTS One percent (n = 695) of individuals experienced breech birth (n = 401, 57.6% vaginally). Most fetuses presented frank breech (57%), with 19% complete, 18% footling/kneeling, and 5% unknown type of breech presentation. Among all breech labors, there were high rates of intrapartum transfer and cesarean birth compared to cephalic presentation (OR 9.0, 95% CI 7.7-10.4 and OR 18.6, 95% CI 15.9-21.7, respectively), with no substantive difference based on parity, planned site of birth, or level of care integration into the health system. For all types of breech presentations, there was increased risk for nearly all assessed neonatal outcomes including hospital transfer, NICU admission, birth injury, and umbilical cord prolapse. Breech presentation was also associated with increased risk of intrapartum/neonatal death (OR 8.5, 95% CI 4.4-16.3), even after congenital anomalies were excluded. CONCLUSIONS All types of breech presentations in community birth settings are associated with increased risk of adverse neonatal outcomes. These research findings contribute to informed decision-making and reinforce the need for breech training and research and an increase in accessible, high-quality care for planned vaginal breech birth in US hospitals.

Abstract
BACKGROUND Preventing postpartum depression (PPD) is the most common self-reported motivation for human maternal placentophagy, yet very little systematic research has assessed mental health following placenta consumption. Our aim was to compare PPD screening scores of placenta consumers and non-consumers in a community birth setting, using propensity score matching to address anticipated extensive confounding. METHODS We used a medical records-based data set (n = 6038) containing pregnancy, birth, and postpartum information for US women who planned and completed community births. We first compared PPD screening scores as measured by the Edinburgh Postpartum Depression Scale (EPDS) of individuals who consumed their placenta to those who did not, with regard to demographics, pregnancy characteristics, and history of mental health challenges. Matching placentophagic (n = 1876) and non-placentophagic (n = 1876) groups were then created using propensity scores. The propensity score model included more than 90 variables describing medical and obstetric history, demographics, pregnancy characteristics, and intrapartum and postpartum complications, thus addressing confounding by all of these variables. We then used logistic regression to compare placentophagic to non-placentophagic groups based on commonly-cited EPDS cutoff values (≥ 11; ≥ 13) for likely PPD. RESULTS In the unmatched and unadjusted analysis, placentophagy was associated with an increased risk of PPD. In the matched sample, 9.9% of women who ate their placentas reported EPDS ≥ 11, compared to 8.4% of women who did not (5.5% and 4.8%, respectively, EPDS ≥ 13 or greater). After controlling for over 90 variables (including prior mental health challenges) in the matched and adjusted analysis, placentophagy was associated with an increased risk of PPD between 15 and 20%, depending on the published EPDS cutoff point used. Numerous sensitivity analyses did not alter this general finding. CONCLUSIONS Placentophagic individuals in our study scored higher on an EPDS screening than carefully matched non-placentophagic controls. Why placentophagic women score higher on the EPDS remains unclear, but we suspect reverse causality plays an important role. Future research could assess psychosocial factors that may motivate some individuals to engage in placentophagy, and that may also indicate greater risk of PPD.

Abstract
INTRODUCTIONGenital tract injury during childbirth contributes to short and long-term problems, including postpartum hemorrhage, incontinence, and pelvic organ prolapse. The purpose of this study was to examine which sets of second stage management techniques employed by midwives attending births in the community setting are associated with genital tract injury and subsequent postpartum hemorrhage.METHODSData from primiparous individuals within the Midwives Alliance of North America (MANA) Stats 2.0 (2004–2009) database were used for this analysis. Latent mixture modeling identified classes (groups) within the sample that are most similar based on 11 different characteristics of second stage management as noted by midwives in their birth notes, including hands-on management techniques during birth, maternal positioning at birth, and water birth.RESULTSThree classes of second stage management techniques best fit this complex dataset. The patterns of techniques used by midwives were only marginally associated with better or worse genital tract outcomes independent of other factors. Two covariables, however, advanced maternal age (OR1.60, 95% CI 1.09–2.34) and births with low fetal heart rate during second stage (OR2.82, 95% CI 1.93–4.10)—were associated with severe genital tract injury. Postpartum hemorrhage was more likely for the two classes where midwives used more hands-on management during second stage, even when considering presence of genital tract injury (OR1.33, 95% CI 1.09–1.63). This study highlights the complex second stage circumstances that interact with management techniques, which together shape or contribute to both genital tissue and hemorrhage outcomes.

Abstract
OBJECTIVE To evaluate patterns of mother-infant sleeping behaviors among US-based mothers who received care from midwives and breastfed their infants the majority of time at 6 weeks postpartum. STUDY DESIGN Infant sleep locations were reported for 24 915 mother-infant dyads followed through 6 weeks postpartum, following midwife-led singleton births. Using data derived from medical records, we used multinomial logistic regression to identify predictors of sleep location. RESULTS The median maternal age was 31 years (IQR, 27-34 years). The majority were White (84.5%), reported having a partner or spouse (95%), had a community birth (87%), and reported bedsharing with their infant for part (13.2%) or most of the night (43.8%). In the adjusted analysis, positive predictors of always bedsharing included increasing maternal age (OR, 1.17; 95% CI, 1.13-1.21; per 5 years), cesarean birth (OR, 1.49; 95% CI, 1.18-1.86), Medicaid eligibility (OR, 1.76; 95% CI, 1.62-1.91), and maternal race/ethnicity (Black OR, 1.40 [95% CI, 1.09-1.79]; Latinx OR, 1.53 [95% CI, 1.35-1.74]; multiracial OR, 1.69 [95% CI, 1.39-2.07]). Negative predictors of bedsharing included having a partner/spouse (OR, 0.66; 95% CI, 0.56-0.77) and birth location in hospitals (OR, 0.56; 95% CI, 0.49-0.64) or birthing centers (OR, 0.48; 95% CI, 0.44-0.51). Partial breastfeeding dyads were less likely to bedshare than those who were exclusively breastfeeding (always bedsharing OR, 0.48 [95% CI, 0.41-0.56]; sometimes bedsharing OR 0.69 [95% CI, 0.56-0.83]). CONCLUSIONS These data suggest that cosleeping is common among US families who choose community births, most of whom exclusively breastfeed through at least 6 weeks.

[PMID: 35783483 PMCID: PMC9249551 DOI: 10.1016/j.eclinm.2022.101447] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2022] [Revised: 04/19/2022] [Accepted: 04/25/2022] [Indexed: 11/29/2022] Open
Abstract
BACKGROUND Friedman's curve, despite acknowledged limitations, has greatly influenced labour management. Interventions to hasten birth are now ubiquitous, challenging the contemporary study of normal labour. Our primary purpose was to characterise normal active labour and pushing durations in a large, contemporary sample experiencing minimal intervention, stratified by parity, age, and body mass index (BMI). METHODS This is a secondary analysis of the national, validated Midwives Alliance of North America 4·0 (MANA Stats) data registry (n = 75,243), prospectively collected between Jan 1, 2012 and Dec 31, 2018 to describe labour and birth in home and birth center settings where common obstetric interventions [i.e., oxytocin, planned cesarean] are not available. The MANA Stats cohort includes pregnant people who intended birth in these settings and prospectively collects labour and birth processes and outcomes regardless of where birth or postpartum care ultimately occurs. Survival curves were calculated to estimate labour duration percentiles (e.g. 10th, 50th, 90th, and others of interest), by parity and sub-stratified by age and BMI. FINDINGS Compared to multiparous women (n = 32,882), nulliparous women (n = 15,331) had significantly longer active labour [e.g., median 7.5 vs. 3.3 h; 95th percentile 34.8 vs. 12.0 h] and significantly longer pushing phase [e.g., median 1.1 vs. 0.2 h; 95th percentile 5.5 vs. 1.1 h]. Among nulliparous women, maternal age >35 was associated with longer active first stage of labour and longer pushing phase, and BMI >30 kg/m² was associated with a longer active first stage of labour but a shorter pushing phase. Patterns among multiparous women were different, with those >35 years of age experiencing a slightly more rapid active labour and no difference in pushing duration, and those with BMI >30 kg/m² experiencing a slightly longer active labour but, similarly, no difference in pushing duration. INTERPRETATION Nulliparous women had significantly longer active first stage and pushing phase durations than multiparous women, with further variation noted by age and by BMI. Contemporary US women with low-risk pregnancies who intended birth in settings absent common obstetric interventions and in spontaneous labour with a live, vertex, term, singleton, non-anomalous fetus experienced labour durations that were often longer than prior characterizations, particularly among nulliparous women. Results overcome prior and current sampling limitations to refine understanding of normal labour durations and time thresholds signaling 'labour dystocia'.

Abstract
OBJECTIVE Investigate maternal and neonatal outcomes following waterbirth. DESIGN Retrospective cohort study, with propensity score matching to address confounding. SETTING Community births, United States. SAMPLE Medical records-based registry data from low-risk births were used to create waterbirth and land birth groups (n = 17 530 each), propensity score-matched on >80 demographic and pregnancy risk covariables. METHODS Logistic regression models compared outcomes between the matched waterbirth and land birth groups. MAIN OUTCOME MEASURES Maternal: immediate postpartum transfer to a hospital, any genital tract trauma, severe (3rd/4th degree) trauma, haemorrhage >1000 mL, diagnosed haemorrhage regardless of estimated blood loss, uterine infection, uterine infection requiring hospitalisation, any hospitalisation in the first 6 weeks. Neonatal: umbilical cord avulsion; immediate neonatal transfer to a hospital; respiratory distress syndrome; any hospitalisation, neonatal intensive care unit (NICU) admission, or neonatal infection in the first 6 weeks; and neonatal death. RESULTS Waterbirth was associated with improved or no difference in outcomes for most measures, including neonatal death (adjusted odds ratio [aOR] 0.56, 95% CI 0.31-1.0), and maternal or neonatal hospitalisation in the first 6 weeks (aOR 0.87, 95% CI 0.81-0.92 and aOR 0.95, 95% CI 0.90-0.99, respectively). Increased morbidity in the waterbirth group was observed for two outcomes only: uterine infection (aOR 1.25, 95% CI 1.05-1.48) (but not hospitalisation for infection) and umbilical cord avulsion (aOR 1.57, 95% CI 1.37-1.82). Our results are concordant with other studies: waterbirth is neither as harmful as some current guidelines suggest, nor as benign as some proponents claim. TWEETABLE ABSTRACT New study demonstrates #waterbirth is neither as harmful as some current guidelines suggest, nor as benign as some proponents claim. @TheUpliftLab @BovbjergMarit @31415926abc @NICHD_NIH.

Abstract
OBJECTIVE To describe rates of maternal and perinatal birth outcomes for community births and to compare outcomes by planned place of birth (home vs state-licensed, freestanding birth center) in a Washington State birth cohort, where midwifery practice and integration mirrors international settings. METHODS We conducted a retrospective cohort study including all births attended by members of a statewide midwifery professional association that were within professional association guidelines and met eligibility criteria for planned birth center birth (term gestation, singleton, vertex fetus with no known fluid abnormalities at term, no prior cesarean birth, no hypertensive disorders, no prepregnancy diabetes), from January 1, 2015 through June 30, 2020. Outcome rates were calculated for all planned community births in the cohort. Estimated relative risks were calculated comparing delivery and perinatal outcomes for planned births at home to state-licensed birth centers, adjusted for parity and other confounders. RESULTS The study population included 10,609 births: 40.9% planned home and 59.1% planned birth center births. Intrapartum transfers to hospital were more frequent among nulliparous individuals (30.5%; 95% CI 29.2-31.9) than multiparous individuals (4.2%; 95% CI 3.6-4.6). The cesarean delivery rate was 11.4% (95% CI 10.2-12.3) in nulliparous individuals and 0.87% (95% CI 0.7-1.1) in multiparous individuals. The perinatal mortality rate after the onset of labor (intrapartum and neonatal deaths through 7 days) was 0.57 (95% CI 0.19-1.04) per 1,000 births. Rates for other adverse outcomes were also low. Compared with planned birth center births, planned home births had similar risks in crude and adjusted analyses. CONCLUSION Rates of adverse outcomes for this cohort in a U.S. state with well-established and integrated community midwifery were low overall. Birth outcomes were similar for births planned at home or at a state-licensed, freestanding birth center.

[PMID: 33058197 PMCID: PMC8923081 DOI: 10.1111/birt.12506] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/30/2020] [Revised: 09/03/2020] [Accepted: 09/11/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Fetal macrosomia is associated with negative outcomes, although less is known about how severities of macrosomia influence these outcomes. Planned community births in the United States have higher rates of gestational age-adjusted macrosomia than planned hospital births, providing a novel population to examine macrosomia morbidity. METHODS Maternal and neonatal outcomes associated with grade 1 (4000-4499 g), grade 2 (4500-4999 g), and grade 3 (≥5000 g) macrosomia were compared to normal birthweight newborns (2500-3999 g), using data from the MANA Statistics Project-a registry of planned community births, 2012-2018 (n = 68 966). Outcomes included perineal trauma, postpartum hemorrhage, cesarean birth, neonatal birth injury, shoulder dystocia, neonatal respiratory distress, neonatal intensive care unit (NICU) stay >24 hours, and perinatal death. Logistic regressions controlled for parity and mode of birth, obesity, gestational diabetes, and preeclampsia. RESULTS Sixteen percent of the sample were grade 1 macrosomic, 3.3% were grade 2 macrosomic, and 0.4% were grade 3 macrosomic. Macrosomia grades 1-3 were associated in a dose-response fashion with higher odds of all outcomes, compared to non-macrosomia. The adjusted odds ratios and 95% confidence intervals for postpartum hemorrhage for grade 1, grade 2, and grade 3 macrosomia vs normal birthweight were 1.75 (1.56-1.96), 2.12 (1.70-2.63), and 5.18 (3.47-7.74), respectively. Other outcomes had similar patterns. DISCUSSION The adjusted odds of negative outcomes increase as grade of macrosomia increases in planned community births; results are comparable with the published literature. Pre-birth fetal weight estimation is imprecise; prenatal supports and shared decision-making processes should reflect these complexities.

Abstract
BACKGROUND Postpartum hemorrhage (PPH) is a potential childbirth complication. Little is known about how third-stage labor is managed by midwives in the United States, including use of uterotonic medication during community birth. Access to uterotonic medication may vary based on credentials of the midwife or state regulations governing midwifery. METHODS Using data from the Midwives of North America 2.0 database (2004-2009), we describe the PPH incidence for women giving birth in the community, their demographic and clinical characteristics, and methods used by midwives to address PPH. We also examined PPH rates by midwifery credentials and by the presence of regulations for legal midwifery practice. RESULTS Of the 17 836 vaginal births, 15.9% had blood loss of over 500 mL and 3.3% had 1000 mL or greater blood loss. Midwives used pharmaceuticals to prevent or treat postpartum bleeding in 6.3% and 13.9% of births, respectively, and the rate of hospital transfer after birth was 1.4% (n = 247). In adjusted analyses, PPH was less likely when births occurred at home vs a birth center, if the midwife had a CNM/CM credential vs a CPM/LM/LDM credential, or if the woman was multiparous without a history of PPH or prior cesarean birth. PPH was more likely in states with barriers to midwifery practice compared with regulated states (OR: 1.26; 95% CI, 1.16-1.38). CONCLUSIONS Women giving birth in the community experienced low overall incidence of PPH-related hospital transfer. However, the occurrence of PPH itself would likely be reduced with improved legal access to uterotonic medication.

Abstract
Although Apgar scores are commonly used as proxy outcomes, little evidence exists in support of the most common cutpoints (<7, <4). We used 2 data sets to explore this issue: one contained planned community births from across the United States (n = 52,877; 2012-2016), and the other contained hospital births from California (n = 428,877; 2010). We treated 5-minute Apgars as clinical "tests," compared against 18 known outcomes; we calculated sensitivity, specificity, positive and negative predictive values, and the area under the receiver operating characteristic curve for each. We used 3 different criteria to determine optimal cutpoints. Results were very consistent across data sets, outcomes, and all subgroups: The cutpoint that maximizes the trade-off between sensitivity and specificity is universally <9. However, extremely low positive predictive values for all outcomes at <9 indicate more misclassification than is acceptable for research. The areas under the receiver operating characteristic curves (which treat Apgars as quasicontinuous) were generally indicative of adequate discrimination between infants destined to experience poor outcomes and those not; comparing median Apgars between groups might be an analytical alternative to dichotomizing. Nonetheless, because Apgar scores are not clearly on any causal pathway of interest, we discourage researchers from using them unless the motivation for doing so is clear.

Abstract
BACKGROUND Recently WHO researchers described seven dimensions of mistreatment in maternity care that have adverse impacts on quality and safety. Applying the WHO framework for quality care, service users partnered with NGOs, clinicians, and researchers, to design and conduct the Giving Voice to Mothers (GVtM)-US study. METHODS Our multi-stakeholder team distributed an online cross-sectional survey to capture lived experiences of maternity care in diverse populations. Patient-designed items included indicators of verbal and physical abuse, autonomy, discrimination, failure to meet professional standards of care, poor rapport with providers, and poor conditions in the health system. We quantified the prevalence of mistreatment by race, socio-demographics, mode of birth, place of birth, and context of care, and describe the intersectional relationships between these variables. RESULTS Of eligible participants (n = 2700), 2138 completed all sections of the survey. One in six women (17.3%) reported experiencing one or more types of mistreatment such as: loss of autonomy; being shouted at, scolded, or threatened; and being ignored, refused, or receiving no response to requests for help. Context of care (e.g. mode of birth; transfer; difference of opinion) correlated with increased reports of mistreatment. Experiences of mistreatment differed significantly by place of birth: 5.1% of women who gave birth at home versus 28.1% of women who gave birth at the hospital. Factors associated with a lower likelihood of mistreatment included having a vaginal birth, a community birth, a midwife, and being white, multiparous, and older than 30 years. Rates of mistreatment for women of colour were consistently higher even when examining interactions between race and other maternal characteristics. For example, 27.2% of women of colour with low SES reported any mistreatment versus 18.7% of white women with low SES. Regardless of maternal race, having a partner who was Black also increased reported mistreatment. CONCLUSION This is the first study to use indicators developed by service users to describe mistreatment in childbirth in the US. Our findings suggest that mistreatment is experienced more frequently by women of colour, when birth occurs in hospitals, and among those with social, economic or health challenges. Mistreatment is exacerbated by unexpected obstetric interventions, and by patient-provider disagreements.

Nurses’ attitudes towards the implementation of the Mother-Baby Friendly Initiative in selected primary healthcare facilities at Makhuduthamaga Municipality, Limpopo province. Curationis 2019.

Abstract
Background The implementation of the Mother-Baby Friendly Initiative (MBFI) strategy demonstrated its capabilities to improve global children’s health and maternal survival. However, its implementation in primary healthcare (PHC) facilities remains a challenge as many nurses are reluctant to adopt it for the improvement of child and maternal healthcare services in their respective clinics. Objectives The primary objective of this study was to determine the attitudes of nurses towards the implementation of the MBFI in selected PHC facilities in the Makhuduthamaga Municipality, Limpopo province. Method This study used a quantitative, descriptive design, and all respondents were conveniently sampled. A self-administered questionnaire was used to collect data. One-hundred and seventy-seven questionnaires were distributed, and 153 nurses responded and completed the questionnaire. The Statistical Package for Social Sciences version 23 was used to analyse data. Results Results show that the majority of nurses (professional nurses [PNs] = 65, 78%; enrolled nurses [ENs] = 18, 72%; enrolled nursing auxiliaries [ENAs] = 23, 51%) had a positive attitude towards the MBFI strategy implementation as they agreed that it increased breastfeeding rates. Most PNs (n = 58, 70%) and ENs (n = 15, 60%) showed positive attitudes towards exclusive breastfeeding (EBF) as they agreed that it was the ideal feeding option for any child, and most ENAs (n = 38, 84%) showed a negative attitude as they disagreed that EBF was the ideal feeding option for any child. Conclusion In this study, most PNs and ENs had a positive attitude in all the aspects that determined their attitudes towards MBFI strategy implementation. A concern is the fact that most ENAs showed negative attitudes in almost all the statements that were in line with the principles of MBFI, as they disagreed in most aspects. Therefore, this study recommends that on-going orientation and trainings should be offered to all nurses including ENAs to equip them with information that can assist in changing their attitudes towards MBFI implementation in PHC facilities.

Abstract
BACKGROUND Limited systematic research on maternal placentophagy is available to maternity care providers whose clients/patients may be considering this increasingly popular practice. Our purpose was to characterize the practice of placentophagy and its attendant neonatal outcomes among a large sample of women in the United States. METHODS We used a medical records-based data set (n = 23 242) containing pregnancy, birth, and postpartum information for women who planned community births. We used logistic regression to determine demographic and clinical predictors of placentophagy. Finally, we compared neonatal outcomes (hospitalization, neonatal intensive unit admission, or neonatal death in the first 6 weeks) between placenta consumers and nonconsumers, and participants who consumed placenta raw vs cooked. RESULTS Nearly one-third (30.8%) of women consumed their placenta. Consumers were more likely to have reported pregravid anxiety or depression compared with nonconsumers. Most (85.3%) placentophagic mothers consumed their placentas in encapsulated form, and nearly half (48.4%) consumed capsules containing dehydrated, uncooked placenta. Placentophagy was not associated with any adverse neonatal outcomes. Women with home births were more likely to engage in placentophagy than women with birth center births. The most common reason given (73.1%) for engaging in placentophagy was to prevent postpartum depression. [Corrections added on 16 May 2018, after first online publication: The percentage values in the Results sections were updated.] CONCLUSIONS: The majority of women consumed their placentas in uncooked/encapsulated form and hoping to avoid postpartum depression, although no evidence currently exists to support this strategy. Preparation technique (cooked vs uncooked) did not influence adverse neonatal outcomes. Maternity care providers should discuss the range of options available to prevent/treat postpartum depression, in addition to current evidence with respect to the safety of placentophagy.

Abstract
BACKGROUND Approximately 22% of women in the United States live in rural areas with limited access to obstetric care. Despite declines in hospital-based obstetric services in many rural communities, midwifery care at home and in free standing birth centers is available in many rural communities. This study examines maternal and neonatal outcomes among planned home and birth center births attended by midwives, comparing outcomes for rural and nonrural women. METHODS Using the Midwives Alliance of North America Statistics Project 2.0 dataset of 18 723 low-risk, planned home, and birth center births, rural women (n = 3737) were compared to nonrural women. Maternal outcomes included mode of delivery (cesarean and instrumental delivery), blood transfusions, severe events, perineal lacerations, or transfer to hospital and a composite (any of the above). The primary neonatal outcome was a composite of early neonatal intensive care unit or hospital admissions (longer than 1 day), and intrapartum or neonatal deaths. Analysis involved multivariable logistic regression, controlling for sociodemographics, antepartum, and intrapartum risk factors. RESULTS Rural women had different risk profiles relative to nonrural women and reduced risk of adverse maternal and neonatal outcomes in bivariable analyses. However, after adjusting for risk factors and confounders, there were no significant differences for a composite of maternal (adjusted odds ratio [aOR] 1.05 [95% confidence interval {CI} 0.93-1.19]) or neonatal (aOR 1.13 [95% CI 0.87-1.46]) outcomes between rural and nonrural pregnancies. CONCLUSION Among this sample of low-risk women who planned midwife-led community births, no increased risk was detected by rural vs nonrural status.

Background Clinical data registry is designed to collect and manage information about the practices and outcomes of a patient population for improving the quality and safety of care and facilitating novel researches. Semantic interoperability is a challenge when integrating the data from more than one clinical data registry. The openEHR approach can represent the information and knowledge semantics by multi-level modeling, and it advocates the use of collaborative modeling to facilitate reusing existing archetypes with consistent semantics so as to be a potential solution to improve the semantic interoperability. Methods This paper proposed an openEHR based approach to improve the semantic interoperability of clinical data registry. The approach consists of five steps: clinical data registry meta-information collection, data element definition, archetype modeling, template editing, and implementation. Through collaborative modeling and maximum reusing of existing archetype at the archetype modeling step, the approach can improve semantic interoperability. To verify the feasibility of the approach, this paper conducted a case study of building a Coronary Computed Tomography Angiography (CCTA) registry that can interoperate with an existing Electronic Health Record (EHR) system. Results The CCTA registry includes 183 data elements, which involves 20 archetypes. A total number of 45 CCTA data elements and EHR data elements have semantic overlap. Among them, 38 (84%) CCTA data elements can be found in the 10 reused EHR archetypes. These corresponding clinical data can be collected from the EHR system directly without transformation. The other 7 (16%) CCTA data elements correspond to one coarse-grained EHR data elements, and these clinical data can be collected with mapping rules. The results show that the approach can improve semantic interoperability of clinical data registry. Conclusions Using an openEHR based approach to develop clinical data registry can improve the semantic interoperability. Meanwhile, some challenges for broader semantic interoperability are identified, including domain experts’ involvement, archetype sharing and reusing, and archetype semantic mapping. Collaborative modeling, easy-to-use tools, and semantic relationship establishment are potential solutions for these challenges. This study provides some experience and insight about clinical modeling and clinical data registry development.

Abstract
BACKGROUND There is little agreement on who is a good candidate for community (home or birth center) birth in the United States. METHODS Data on n=47 394 midwife-attended, planned community births come from the Midwives Alliance of North America Statistics Project. Logistic regression quantified the independent contribution of 10 risk factors to maternal and neonatal outcomes. Risk factors included: primiparity, advanced maternal age, obesity, gestational diabetes, preeclampsia, postterm pregnancy, twins, breech presentation, history of cesarean and vaginal birth, and history of cesarean without history of vaginal birth. Models controlled additionally for Medicaid, race/ethnicity, and education. RESULTS The independent contributions of maternal age and obesity were quite modest, with adjusted odds ratios (AOR) less than 2.0 for all outcomes: hospital transfer, cesarean, perineal trauma, postpartum hemorrhage, low/very-low Apgar, maternal or neonatal hospitalization, NICU admission, and fetal/neonatal death. Breech was strongly associated with morbidity and fetal/neonatal mortality (AOR 8.2, 95% CI, 3.7-18.4). Women with a history of both cesarean and vaginal birth fared better than primiparas across all outcomes; however, women with a history of cesarean but no prior vaginal births had poor outcomes, most notably fetal/neonatal demise (AOR 10.4, 95% CI, 4.8-22.6). Cesarean births were most common in the breech (44.7%), preeclampsia (30.6%), history of cesarean without vaginal birth (22.1%), and primipara (11.0%) groups. DISCUSSION The outcomes of labor after cesarean in women with previous vaginal deliveries indicates that guidelines uniformly prohibiting labor after cesarean should be reconsidered for this subgroup. Breech presentation has the highest rate of adverse outcomes supporting management of vaginal breech labor in a hospital setting.

Abstract
Many organizations collect and make available perinatal data for research and quality improvement initiatives. Analysis of existing data and use of retrospective study design has many advantages for perinatal researchers. These advantages include large samples, inclusion of women from diverse groups, data reflective of actual clinical processes and outcomes, and decreased risk of direct maternal and fetal harm. We review 11 publicly available datasets relevant to perinatal research and quality improvement, detail the availability of interactive websites, and discuss strategies to locate additional datasets. While analysis of existing data has limitations, it may provide statistical power to study rare perinatal outcomes, support research applicable to diverse populations, and facilitate timely and ethical well-woman research immediately relevant to clinical care.

Abstract
BACKGROUND Women who seek vaginal birth after cesarean delivery may find limited in-hospital options. Increasing numbers of women in the United States are delivering by vaginal birth after cesarean delivery out-of-hospital. Little is known about neonatal outcomes among those who deliver by vaginal birth after cesarean delivery in- vs out-of-hospital. OBJECTIVE The purpose of this study was to compare neonatal outcomes between women who deliver via vaginal birth after cesarean delivery in-hospital vs out-of-hospital (home and freestanding birth center). STUDY DESIGN We conducted a retrospective cohort study using 2007-2010 linked United States birth and death records to compare singleton, term, vertex, nonanomolous, and liveborn neonates who delivered by vaginal birth after cesarean delivery in- or out-of-hospital. Descriptive statistics and multivariate regression analyses were conducted to estimate unadjusted, absolute, and relative birth-setting risk differences. Analyses were stratified by parity and history of vaginal birth. Sensitivity analyses that involved 3 transfer status scenarios were conducted. RESULTS Of women in the United States with a history of cesarean delivery (n=1,138,813), only a small proportion delivered by vaginal birth after cesarean delivery with the subsequent pregnancy (n=109,970; 9.65%). The proportion of home vaginal birth after cesarean delivery births increased from 1.78-2.45%. A pattern of increased neonatal morbidity was noted in unadjusted analysis (neonatal seizures, Apgar score <7 or <4, neonatal seizures), with higher morbidity noted in the out-of-hospital setting (neonatal seizures, 23 [0.02%] vs 6 [0.19%; P<.001]; Apgar score <7, 2859 [2.68%] vs 139 [4.42%; P<.001; Apgar score <4, 431 [0.4%] vs 23 [0.73; P=.01]). A similar, but nonsignificant, pattern of increased risk was observed for neonatal death and ventilator support among those neonates who were born in the out-of-hospital setting. Multivariate regression estimated that neonates who were born in an out-of-hospital setting had higher odds of poor outcomes (neonatal seizures [adjusted odds ratio, 8.53; 95% confidence interval, 2.87-25.4); Apgar score <7 [adjusted odds ratio, 1.62; 95% confidence interval, 1.35-1.96]; Apgar score <4 [adjusted odds ratio, 1.77; 95% confidence interval, 1.12-2.79]). Although the odds of neonatal death (adjusted odds ratio, 2.1; 95% confidence interval, 0.73-6.05; P=.18) and ventilator support (adjusted odds ratio, 1.36; 95% confidence interval, 0.75-2.46) appeared to be increased in out-of-hospital settings, findings did not reach statistical significance. Women birthing their second child by vaginal birth after cesarean delivery in out-of-hospital settings had higher odds of neonatal morbidity and death compared with women of higher parity. Women who had not birthed vaginally prior to out-of-hospital vaginal birth after cesarean delivery had higher odds of neonatal morbidity and mortality compared with women who had birthed vaginally prior to out-of-hospital vaginal birth after cesarean delivery. Sensitivity analyses generated distributions of plausible alternative estimates by outcome. CONCLUSION Fewer than 1 in 10 women in the United States with a previous cesarean delivery delivered by vaginal birth after cesarean delivery in any setting, and increasing proportions of these women delivered in an out-of-hospital setting. Adverse outcomes were more frequent for neonates who were born in an out-of-hospital setting, with risk concentrated among women birthing their second child and women without a history of vaginal birth. This information urgently signals the need to increase availability of in-hospital vaginal birth after cesarean delivery and suggests that there may be benefit associated with increasing options that support physiologic birth and may prevent primary cesarean delivery safely. Results may inform evidence-based recommendations for birthplace among women who seek vaginal birth after cesarean delivery.

Abstract
In 2014, the American College of Nurse-Midwives (ACNM) launched a project called Clarity in Collaboration to develop data definitions related to midwifery and maternity care delivery processes. These definitions are needed to ensure midwifery care delivered in collaborative care models is accurately and consistently captured in clinical documentation systems, data registries, and systems being developed as part of health care restructuring and payment reform. The Clarity in Collaboration project builds on the efforts of the Women's Health Registry Alliance (WHRA), which was recently established by the American College of Obstetricians and Gynecologists. Clarity in Collaboration mirrored the process used by ReVITALize, WHRA's first maternity data standardization project, which focused on establishing standardized clinical data definitions for obstetrics. The ACNM Clarity in Collaboration project brought together maternity and midwifery care experts to complete a year-long consensus process, including a period of public comment, resulting in development of 20 concept definitions. These definitions can be used to describe midwifery care within the context of collaborative care models. This article provides a summary of the ACNM Clarity in Collaboration process with discussion of implications for maternity data collection.

Abstract
INTRODUCTION Data on the safety of waterbirth in the United States are lacking. METHODS We used data from the Midwives Alliance of North America Statistics Project, birth years 2004 to 2009. We compared outcomes of neonates born underwater waterbirth (n = 6534), neonates not born underwater nonwaterbirth (n = 10,290), and neonates whose mothers intended a waterbirth but did not have one intended waterbirth (n = 1573). Neonatal outcomes included a 5-minute Apgar score of less than 7, neonatal hospital transfer, and hospitalization or neonatal intensive care unit (NICU) admission in the first 6 weeks. Maternal outcomes included genital tract trauma, postpartum hospital transfer, and hospitalization or infection (uterine, endometrial, perineal) in the first 6 weeks. We used logistic regression for all analyses, controlling for primiparity. RESULTS Waterbirth neonates experienced fewer negative outcomes than nonwaterbirth neonates: the adjusted odds ratio (aOR) for hospital transfer was 0.46 (95% confidence interval [CI], 0.32-0.68; P < .001); the aOR for infant hospitalization in the first 6 weeks was 0.75 (95% CI, 0.63-0.88; P < .001); and the aOR for NICU admission was 0.59 (95% CI, 0.46-0.76; P < .001). By comparison, neonates in the intended waterbirth group experienced more negative outcomes than the nonwaterbirth group, although only 5-minute Apgar score was significant (aOR, 2.02; 95% CI, 1.40-2.93; P < 0001). For women, waterbirth (compared to nonwaterbirth) was associated with fewer postpartum transfers (aOR, 0.65; 95% CI, 0.50-0.84; P = .001) and hospitalizations in the first 6 weeks (aOR, 0.72; 95% CI, 0.59-0.87; P < 0.001) but with an increased odds of genital tract trauma (aOR, 1.11; 95% CI, 1.04-1.18; P = .002). Waterbirth was not associated with maternal infection. Women in the intended waterbirth group had increased odds for all maternal outcomes compared to women in the nonwaterbirth group, although only genital tract trauma was significant (aOR, 1.67; 95% CI, 1.49-1.87; P < .001). DISCUSSION Waterbirth confers no additional risk to neonates; however, waterbirth may be associated with increased risk of genital tract trauma for women.

Abstract
In the past month, two new studies have been released-one in The New England Journal of Medicine (NEJM; Snowden et al., 2015) and the other in the Canadian Medical Association Journal (Hutton et al., 2015)-comparing out-of-hospital birth outcomes to hospital birth outcomes. These studies join a growing body of literature that consistently shows high rates of obstetric intervention in hospitals and also show low risk to neonates regardless of setting. However, the recent NEJM study found a small but statistically significant increase in risk for perinatal mortality for babies born out of hospital. Jeanette McCulloch of BirthSwell (http://www.birthswell.com) interviews Melissa Cheyney, PhD, CPM, LDM, medical anthropologist, chair of the Midwives Alliance Division of Research, and lead author on the largest study of outcomes for planned home births in the United States to date (Cheyney et al., 2014a), and Jonathan Snowden, PhD, epidemiologist and assistant professor in the Department of Obstetrics and Gynecology and School of Public Health at Oregon Health and Science University. Snowden is also the lead author of the recent NEJM study.

Abstract
BACKGROUND In the United States, the number of planned home vaginal births after cesarean (VBACs) has increased. This study describes the maternal and neonatal outcomes for women who planned a VBAC at home with midwives who were contributing data to the Midwives Alliance of North America Statistics Project 2.0 cohort during the years 2004-2009. METHOD Two subsamples were created from the parent cohort: 12,092 multiparous women without a prior cesarean and 1,052 women with a prior cesarean. Descriptive statistics were calculated for maternal and neonatal outcomes for both groups. Sensitivity analyses comparing women with a prior vaginal birth and those who were at the lowest risk with various subgroups in the parent cohort were also conducted. RESULTS Women with a prior cesarean had a VBAC rate of 87 percent, although transfer rates were higher compared with women without a prior cesarean (18% vs 7%, p < 0.001). The most common indication for transfer was failure to progress. Women with a prior cesarean had higher proportions of blood loss, maternal postpartum infections, uterine rupture, and neonatal intensive care unit admissions than those without a prior cesarean. Five neonatal deaths (4.75/1,000) occurred in the prior cesarean group compared with 1.24/1,000 in multiparas without a history of cesarean (p = 0.015). CONCLUSION Although there is a high likelihood of a vaginal birth at home, women planning a home VBAC should be counseled regarding maternal transfer rates and potential for increased risk to the newborn, particularly if uterine rupture occurs in the home setting.

Variation in referrals to secondary obstetrician-led care among primary midwifery care practices in the Netherlands: a nationwide cohort study. BMC Pregnancy Childbirth 2015; 15:42.

Abstract
BACKGROUND The primary aim of this study was to describe the variation in intrapartum referral rates in midwifery practices in the Netherlands. Secondly, we wanted to explore the association between the practice referral rate and a woman's chance of an instrumental birth (caesarean section or vaginal instrumental birth). METHODS We performed an observational study, using the Dutch national perinatal database. Low risk births in all primary care midwifery practices over the period 2008-2010 were selected. Intrapartum referral rates were calculated. The referral rate among nulliparous women was used to divide the practices in three tertile groups. In a multilevel logistic regression analysis the association between the referral rate and the chance of an instrumental birth was examined. RESULTS The intrapartum referral rate varied from 9.7 to 63.7 percent (mean 37.8; SD 7.0), and for nulliparous women from 13.8 to 78.1 percent (mean 56.8; SD 8.4). The variation occurred predominantly in non-urgent referrals in the first stage of labour. In the practices in the lowest tertile group more nulliparous women had a spontaneous vaginal birth compared to the middle and highest tertile group (T1: 77.3%, T2:73.5%, T3: 72.0%). For multiparous women the spontaneous vaginal birth rate was 97%. Compared to the lowest tertile group the odds ratios for nulliparous women for an instrumental birth were 1.22 (CI 1.16-1.31) and 1.33 (CI 1.25-1.41) in the middle and high tertile groups. This association was no longer significant after controlling for obstetric interventions (pain relief or augmentation). CONCLUSIONS The wide variation between referral rates may not be explained by medical factors or client characteristics alone. A high intrapartum referral rate in a midwifery practice is associated with an increased chance of an instrumental birth for nulliparous women, which is mediated by the increased use of obstetric interventions. Midwives should critically evaluate their referral behaviour. A high referral rate may indicate that more interventions are applied than necessary. This may lead to a lower chance of a spontaneous vaginal birth and a higher risk on a PPH. However, a low referral rate should not be achieved at the cost of perinatal safety.

Abstract
OBJECTIVE in midwife-led care models of maternity care, midwives are responsible for intrapartum referrals to the obstetrician or obstetric unit, in order to give their clients access to secondary obstetric care. This study explores the influence of risk perception, policy on routine labour management, and other midwife related factors on intrapartum referral decisions of Dutch midwives. DESIGN a questionnaire was used, in which a referral decision was asked in 14 early labour scenarios (Discrete Choice Experiment or DCE). The scenarios varied in woman characteristics (BMI, gestational age, the preferred birth location, adequate support by a partner, language problems and coping) and in clinical labour characteristics (cervical dilatation, estimated head-to-cervix pressure, and descent of the head). SETTING primary care midwives in the Netherlands. PARTICIPANTS a systematic random selection of 243 practicing primary care midwives. The response rate was 48 per cent (117/243). MEASUREMENTS the Impact Factor of the characteristics in the DCE was calculated using a conjoint analysis. The number of intrapartum referrals to secondary obstetric care in the 14 scenarios of the DCE was calculated as the individual referral score. Risk perception was assessed by respondents׳ estimates of the probability of eight birth outcomes. The associations between midwives׳ policy on management of physiological labour, personal characteristics, workload in the practice, number of midwives in the practice, and referral score were explored. FINDINGS the estimated head-to-cervix pressure and descent of the head had the largest impact on referral decisions in the DCE. The median referral score was five (range 0-14). Estimates of probability on birth outcomes were predominantly overestimating actual risks. Factors significantly associated with a high referral score were: a low estimated probability of a spontaneous vaginal birth (p=0.007), adhering to the active management policy Proactive Support of Labour (PSOL) (p=0.047), and a practice situated in a rural area or small city (p=0.016). KEY CONCLUSIONS there is considerable variation in referral decisions among midwives that cannot be explained by woman characteristics or clinical factors in early labour. A realistic perception of the possibility of a spontaneous vaginal birth and adhering to expectant management can contribute to the prevention of unwarranted medicalisation of physiological childbirth. IMPLICATIONS FOR PRACTICE awareness of variation in referrals and the associated midwife-related factors can stimulate midwives to reflect on their referral behavior. To diminish unwarranted variation, high quality research on the optimal management of a physiological first stage of labour should be performed.
