Outcomes of Planned Hospital Birth Attended by Midwives Compared with Physicians in British Columbia

ABSTRACT: Background: The impact of midwifery versus physician care on perinatal outcomes in a population of women planning birth in hospital has not yet been explored. We compared maternal and newborn outcomes between women planning hospital birth attended by a midwife versus a physician in British Columbia, Canada. Methods: All women planning a hospital birth attended by a midwife during the 2‐year study period who were of sufficiently low‐risk status to meet eligibility requirements for home birth as defined by the British Columbia College of Midwives were included in the study group (n =488). The comparison group included women meeting the same eligibility requirements but planning a physician‐attended birth in hospitals where midwives also practiced (n =572). Outcomes were ascertained from the British Columbia Reproductive Care Program Perinatal Registry to which all hospitals in the province submit data. Results: Adjusted odds ratios for women planning hospital birth attended by a midwife versus a physician were significantly reduced for exposure to cesarean section (OR 0.58, 95% CI 0.39–0.86), narcotic analgesia (OR 0.26, 95% CI 0.18–0.37), electronic fetal monitoring (OR 0.22, 95% CI 0.16–0.30), amniotomy (OR 0.74, 95% CI 0.56–0.98), and episiotomy (OR 0.62, 95% CI 0.42–0.93). The odds of adverse neonatal outcomes were not different between groups, with the exception of reduced use of drugs for resuscitation at birth (OR 0.19, 95% CI 0.04–0.83) in the midwifery group. Conclusions: A shift toward greater proportions of midwife‐attended births in hospitals could result in reduced rates of obstetric interventions, with similar rates of neonatal morbidity.

The Experience of Pregnancy and Birth with Midwives: Results from the Canadian Maternity Experiences Survey

Abstract: Background: In Canada maternity care is publicly funded, and although women may choose their care providers, choices may be limited. The purpose of this study was to compare perceptions of maternity outcomes and experiences of those who received care from midwives with those who received care from other providers. Methods: Based on the 2006 Canadian census, a random sample of women (n = 6,421) who had recently given birth in Canada completed a computer‐assisted telephone interview for the Maternity Experiences Survey. The sample was stratified according to province or territory where birth occurred, age, rural or urban residence, and presence of other children in the home. Those who were 15 years of age and older, gave birth to a singleton baby, and were living with their infant were eligible for inclusion. Results: Women whose primary prenatal providers were midwives had fewer ultrasounds and were more likely to attend prenatal classes and have at least five or more prenatal visits. They were also more likely to rate satisfaction with their maternity experience as “very positive” and be satisfied with information provided on a variety of pregnancy and birth topics if their primary prenatal provider was a midwife. They were almost half as likely to experience induction and 7.33 times more likely to experience a medication‐free delivery. They were more likely to initiate and maintain breastfeeding at 3 and 6 months. Conclusions: Evidence shows that midwifery outcomes and levels of satisfaction meet or exceed Canadian maternity care standards. Facilitation of the continuing integration of midwives as autonomous practitioners throughout Canada is recommended. (BIRTH 38:3 September 2011)     

Consultation,Referral, and Collaboration Between Midwives and Obstetricians: Lessons From New Zealand

There has been substantial growth in the provision of midwifery‐led models of care, yet little is known about the obstetric consultation and referral practices of these midwives or the quality of the collaboration between midwives and obstetricians. This study aimed to describe these processes as they are practised in New Zealand, where midwifery‐led maternity care is the dominant model. A total population postal survey was conducted that included 649 New Zealand midwives who provided midwifery‐led care in 2001. There was a 56.5% response rate, describing care for 4251 women. Within this cohort, there was a 35% consultation rate and 43% of these women had their lead carer role transferred to an obstetrician. However, the midwives continued to provide care in collaboration with obstetricians for 74% of transferred women. Seventy‐two percent of midwives felt that they were well supported by the obstetricians to continue care. Midwifery‐led care is reasonable for the general population of childbearing women, and a 35% consultation rate can be seen as a benchmark for this population. Midwives can, when well supported, provide continuity of care for women who experience complexity during pregnancy and/or birth. Collaboration with obstetricians is possible, but there needs to be further work to describe what successful collaboration is and how it might be fostered.     

Creating Guardians of Physiologic Birth: The Development of an Educational Initiative for Student Midwives in the Netherlands

Women want positive birth experiences with high quality maternity care that is neither too much, too soon, nor too little, too late. Research confirms the effectiveness of midwifery care, and the midwifery approach to birth as physiologic may counter the upward trend of the unnecessary medicalization of birth. The role of guardian of physiologic birth is seen as central to midwifery practice; however, medical hegemony has led to the subordination of midwives, which inhibits them in fulfilling the role as guardian of physiologic birth. Learning to become powerful advocates of physiologic birth creates midwives able to speak up for effective, evidence‐based maternity care and challenge the unnecessary use of obstetric intervention. Midwifery education has a role to fulfil in molding midwives who are able to assume this role. This brief report describes the development of an educational prototype aimed at increasing student midwife agency as an advocate of physiologic birth. This was done using rapid prototyping (RP) methodology, in which important stakeholders gave input and feedback during the educational design and development process. Input from stakeholders led to the inclusion of persuasive communication strategies and discussion and debate as teaching methodologies in order to increase student midwife agency to argue for physiologic birth. Reflective evidence‐based practice, using the Optimality Index‐Netherlands, allowed students to reflect on their practice while providing a framework for discussion. Working with the RP methodology allowed for the development of a prototype that reflected the needs of midwifery stakeholders and was mindful of material and human resources.     

In‐Hospital Birth Center with the Same Medical Guidelines as Standard Care: A Comparative Study of Obstetric Interventions and Outcomes

Background: A challenge of obstetric care is to optimize maternal and infant health outcomes and the mother’s experience of childbirth with the least possible intervention in the normal process. The aim of this study was to investigate the effects of modified birth center care on obstetric procedures during delivery and on maternal and neonatal outcomes. Methods: In a cohort study 2,555 women who signed in for birth center care during pregnancy were compared with all 9,382 low‐risk women who gave birth in the standard delivery ward in the same hospital from March 2004 to July 2008. Odds ratios (OR) were calculated with 95% confidence interval (CI) and adjusted for maternal background characteristics, elective cesarean section, and gestational age. Results: The modified birth center group included fewer emergency cesarean sections (primiparas: OR: 0.69, 95% CI: 0.58–0.83; multiparas: OR: 0.34, 95% CI: 0.23–0.51), and in multiparas the vacuum extraction rate was reduced (OR: 0.42, 95% CI: 0.26–0.67). In addition, epidural analgesia was used less frequently (primiparas: OR: 0.47, 95% CI: 0.41–0.53; multiparas: OR: 0.25, 95% CI: 0.20–0.32). Fetal distress was less frequently diagnosed in the modified birth center group (primiparas: OR: 0.72, 95% CI: 0.59–0.87; multiparas: OR: 0.45, 95% CI: 0.29–0.69), but no statistically significant differences were found in neonatal hypoxia, low Apgar score less than 7 at 5 minutes, or proportion of perinatal deaths (OR: 0.40, 95% CI: 0.14–1.13). Anal sphincter tears were reduced (primiparas: OR: 0.73, 95% CI: 0.55–0.98; multiparas: OR: 0.41, 95% CI: 0.20–0.83). Conclusion: Midwife‐led comprehensive care with the same medical guidelines as in standard care reduced medical interventions without jeopardizing maternal and infant health.

Antenatal Vulvar Pain Management,Labour Management,and Postpartum Care of Women With Vulvodynia: A Survey of Physicians and Midwives

Objective

To examine maternity providers' recommendations for pregnant women with vulvodynia regarding management of vulvar pain and postpartum care, and to examine if, and how, a woman's chronic vulvar pain affects providers' examination and management during labour.

Nurse‐Midwives' Experiences with Planned Home Birth: Impact on Attitudes and Practice

Background: Health care providers' attitudes toward maternity care options influence the nature of informed decision‐making discussions and patient choice. A woman's choice of birth site may be affected by her provider's opinion and practice site. The objectives of this study were to describe American nurse‐midwives' attitudes toward, and experiences with, planned home birth, and to explore correlates and predictors of their attitudes toward planned home birth as measured by the Provider Attitudes towards Planned Home Birth (PAPHB) scale. Methods: A survey instrument, which incorporates the PAPHB and assesses demographic, education, practice, personal experience, and external barrier variables that may predict attitudes toward planned home birth practice, was completed by 1,893 nurse‐midwives. Bivariate analysis identified associations between variables and attitudes. Linear regression modeling identified predictors of attitudes. Results: Variables that significantly predicted favorable attitudes to planned home birth were increased clinical and educational experiences with planned home birth (p < 0.001), increased exposure to planned home birth (p < 0.001), and younger age (p < 0.001). External barriers that significantly predicted less favorable attitudes included financial (p = 0.03) and time (p < 0.001) constraints, inability to access medical consultation (p < 0.001), and fear of peer censure (p < 0.001). Willingness to practice in the home was correlated with factors related to nurse‐midwives' confidence in their management abilities and beliefs about planned home birth safety. Conclusions: The results suggest that nurse‐midwives' choice of practice site and comfort with planned home birth are strongly influenced by the nature and amount of exposure to home birth during professional education or practice experiences, in addition to interprofessional, logistic, and environmental factors. Findings from this research may inform interdisciplinary education and collaborative practice in the area of planned home birth.     

Outcomes Associated with Planned Home and Planned Hospital Births in Low‐Risk Women Attended by Midwives in Ontario,Canada, 2003–2006: A Retrospective Cohort Study

Background: Midwives in Ontario, Canada, provide care in the home and hospital and are required to submit data for all births to the Ontario Ministry of Health database. The purpose of this study was to compare maternal and perinatal/neonatal mortality and morbidity and intrapartum intervention rates for women attended by Ontario midwives who planned a home birth compared with similar low‐risk women who planned a hospital birth between 2003 and 2006. Methods: The database provided outcomes for all women planning a home birth at the onset of labor (n = 6,692) and for a cohort, stratified by parity, of similar low‐risk women planning a hospital birth. Results: The rate of perinatal and neonatal mortality was very low (1/1,000) for both groups, and no difference was shown between groups in perinatal and neonatal mortality or serious morbidity (2.4% vs 2.8%; relative risk [RR], 95% confidence intervals [CI]: 0.84 [0.68–1.03]). No maternal deaths were reported. All measures of serious maternal morbidity were lower in the planned home birth group as were rates for all interventions including cesarean section (5.2% vs 8.1%; RR [95% CI]: 0.64 [0.56, 0.73]). Nulliparas were less likely to deliver at home, and had higher rates of ambulance transport from home to hospital than multiparas planning home birth and had rates of intervention and outcomes similar to, or lower than, nulliparas planning hospital births. Conclusions: Midwives who were integrated into the health care system with good access to emergency services, consultation, and transfer of care provided care resulting in favorable outcomes for women planning both home or hospital births.     

Midwives on the move: comparing the requirements for practice and integration contexts for internationally educated midwives in Canada with the U.S., U.K. and Australia

Midwives have long been internationally mobile, but there has been relatively little attention paid to the requirements that internationally educated midwives (IEMs) must meet to practice and become integrated into the health-care systems of their destination country. This paper examines from a comparative perspective the policy context and integration procedures that IEMs must follow in order to practice in Canada and how this compares with the U.S., the U.K., and Australia. The data upon which this paper is based are largely derived from an analysis of documents and websites for key organisations involved in the integration process supplemented with interviews with key informants influential in the assessment and integration of IEMs. What these data reveal is that the challenges for IEMs derive in large part from the differences in entry to practice requirements—midwifery and nursing training in three of the cases, baccalaureate training in one. Another critical factor is whether bridging or adaptation programmes are available (rarely in the U.S.), and whether they focus more on orientation objectives (as they do in the U.K. and Australia) or also the upgrading of skills (as they do in Canada) critical for IEM professional integration. These different approaches to the integration of IEMs have important implications for the ‘brain drain’ and ‘brain waste’ of much needed midwifery skills in both source and destination countries.     

Birth plans—Impact on mode of delivery,obstetrical interventions,and birth experience satisfaction: A prospective cohort study

Objective

To examine whether the presence of a birth plan was associated with mode of delivery, obstetrical interventions, and patient satisfaction.

Methods

This was a prospective cohort study of singleton pregnancies greater than 34 weeks’ gestation powered to evaluate a difference in mode of delivery. Maternal characteristics, antenatal factors, neonatal characteristics, and patient satisfaction measures were compared between groups. Differences between groups were analyzed using chi‐squared for categorical variables, Fisher exact test for dichotomous variables, and Wilcoxon rank sum test for continuous or ordinal variables.

Results

Three hundred women were recruited: 143 (48%) had a birth plan. There was no significant difference in the risk of cesarean delivery for women with a birth plan compared with those without a birth plan (21% vs 16%, adjusted odds ratio [adjOR] 1.11 [95% confidence interval (CI) 0.61‐2.04]). Women with a birth plan were 28% less likely to receive oxytocin (P < .01), 29% less likely to undergo artificial rupture of membranes (P < .01), and 31% less likely to have an epidural (P < .01). There was no difference in the length of labor (P = .12). Women with a birth plan were less satisfied (P < .01) and felt less in control (P < .01) of their birth experience than those without a birth plan.

Conclusion

Women with and without a birth plan had similar odds of cesarean delivery. Though they had fewer obstetrical interventions, they were less satisfied with their birth experience, compared with women without birth plans. Further research is needed to understand how to improve childbirth‐related patient satisfaction.     

Clinical Outcome of Day 2 Versus Day 3 Embryo Transfer Using Serum-Free Culture Media: A Prospective Randomized Study

Purpose: The objective was to evaluate whether extending the embryo culture period from 2 to 3 days would yield a more optimal selection of viable embryos, thereby increasing the implantation and live birth rates. Methods: Patients undergoing in vitro fertilization with at least one oocyte fertilized were prospectively randomized to 2 or 3 days of embryo culture in serum-free media. On the basis of their morphology and cleavage rate, a maximum of three embryos was selected for transfer. Results: Embryos transferred on day 2 or day 3 were similar morphologically, however, a higher proportion of retarded embryos was observed on day 3. The implantation rate was 15.8 and 14.3% for day 2 and day 3 transfers, respectively. The increase in live birth rate from 18.5 to 22.6%, possibly suggesting a better embryo selection on day 3, was not statistically significant. Conclusions: Extending the embryo culture period from 2 to 3 days had no effect on implantation and live birth rates.
