Midwifery care and out-of-hospital birth settings: how do they reduce unnecessary cesarean section births?

Collaborative model of intrapartum care: qualitative study on barriers and facilitators to implementation in a private Brazilian hospital

INTRODUCTION

A collaborative (midwife-obstetrician) model of intrapartum care (CMIC) is associated with lower caesarean section (CS) rates than physician-led models. In 2019, the largest private maternity hospital in Latin America (14.000 deliveries/year, 89% CS) created a quality improvement initiative to optimise intrapartum care and safely reduce CS in low-risk women managed by its internal team of healthcare providers (HCP). We conducted formative research to identify potential barriers and facilitators to the implementation of a CMIC.

METHODS

Three groups of stakeholders participated in focus groups and interviews: hospital managers and clinical coordinators, HCP working in labour/delivery wards and pregnant women intending to give birth in the hospital. We explored participants' views about the acceptability of implementing a CMIC where a nurse-midwife (NM) on shift would be the main intrapartum HCP, with continuous support/supervision of a dedicated, in-house, obstetrician-gynaecologist (OB-GYN). A thematic analysis approach was used.

RESULTS

12 HCPs, 5 clinical coordinators, 2 hospital managers and 7 women participated. OB-GYNs, coordinators and managers highlighted health system, organisational and structural factors (NMs' limited experience/skills, professional roles, financial reimbursement) as potential barriers. NMs identified logistical and human resources as additional barriers. Women viewed the CMIC with perplexity and insecurity because of cultural beliefs about the dominant role of OB-GYNs, and limited information about NM's capabilities. All professionals agreed that women's acceptance of a CMIC will require educational interventions and communication strategies to inform potential users about the advantages and safety of this model.

CONCLUSION

There are important barriers and facilitators to implement a CMIC in a private Brazilian maternity hospital. Factors related to health system structure and organisation may have the greatest impact. A CMIC is more likely to succeed if stakeholders' concerns about responsibilities, power and financial revenues are addressed, and educational interventions targeted at users are deployed prior to its implementation.

Health system factors and caesarean sections in Kosovo: a cross-sectional study

OBJECTIVE

To investigate the association of caesarean section rates with the health system characteristics in the public hospitals of Kosovo.

DESIGN

Cross-sectional survey.

SETTING

Five largest public hospitals in Kosovo.

PARTICIPANTS

859 women with low-risk deliveries who delivered from April to May 2015 in five public hospitals in Kosovo.

OUTCOME MEASURES

The prespecified outcomes were the crude and adjusted OR of births delivered with caesarean section by health system characteristics such as delivery by the physician who provided antenatal care, health insurance status and other. Additional prespecified outcomes were caesarean section rates and crude ORs for delivery with caesarean in each public hospital.

RESULTS

Women with personal monthly income had increased odds for caesarean (OR 1.55, 95% CI 1.06 to 2.27), as did women with private health insurance coverage (OR 3.44, 95% CI 1.20 to 9.85). Women instructed by a midwife on preparation for delivery had decreasing odds (OR 0.32, 95% CI 0.19 to 0.51) while women having preference for a caesarean had increasing odds for delivery with caesarean (OR 3.84, 95% CI 1.96 to 7.51). The odds for caesarean increased also in the case of delivery by a physician who provided antenatal care (OR 2.06, 95% CI 1.16 to 3.67) and delivery during office hours (OR 2.36, 95% CI 1.37 to 4.05), while delivery at the University Clinical Centre of Kosovo decreased the odds for caesarean (OR 0.46, 95% CI 0.24 to 0.90).

CONCLUSIONS

We found that several health system characteristics are associated with the increase of caesarean sections in a low-risk population of delivering women in public hospitals of Kosovo. These findings should be explored further and addressed via policy measures that would tackle provision of unnecessary caesareans. The study findings could assist Kosovo to develop corrective policies in addressing overuse of caesareans and may provide useful information for other middle-income countries.

Non-clinical interventions to reduce unnecessary caesarean section targeted at organisations, facilities and systems: Systematic review of qualitative studies

OBJECTIVE

When medically indicated, caesarean section can prevent deaths and other serious complications in mothers and babies. Lack of access to caesarean section may result in increased maternal and perinatal mortality and morbidity. However, rising caesarean section rates globally suggest overuse in healthy women and babies, with consequent iatrogenic damage for women and babies, and adverse impacts on the sustainability of maternity care provision. To date, interventions to ensure that caesarean section is appropriately used have not reversed the upward trend in rates. Qualitative evidence has the potential to explain why and how interventions may or may not work in specific contexts. We aimed to establish stakeholders' views on the barriers and facilitators to non-clinical interventions targeted at organizations, facilities and systems, to reduce unnecessary caesarean section.

METHODS

We undertook a systematic qualitative evidence synthesis using a five-stage modified, meta-ethnography approach. We searched MEDLINE, CINAHL, PsychINFO, EMBASE and grey literature databases (Global Index Medicus, POPLINE, AJOL) using pre-defined terms. Inclusion criteria were qualitative and mixed-method studies, investigating any non-clinical intervention to reduce caesarean section, in any setting and language, published after 1984. Study quality was assessed prior to data extraction. Interpretive thematic synthesis was undertaken using a barriers and facilitators lens. Confidence in the resulting Summaries of Findings was assessed using GRADE-CERQual.

RESULTS

8,219 studies were identified. 25 studies were included, from 17 countries, published between 1993-2016, encompassing the views of over 1,565 stakeholders. Nineteen Summary of Findings statements were derived. They mapped onto three distinct themes: Health system, organizational and structural factors (6 SoFs); Human and cultural factors (7 SoFs); and Mechanisms of effect to achieve change factors (6 SoFs). The synthesis showed how inter- and intra-system power differentials, and stakeholder commitment, exert strong mechanisms of effect on caesarean section rates, independent of the theoretical efficacy of specific interventions to reduce them.

CONCLUSIONS

Non-clinical interventions to reduce caesarean section are strongly mediated by organisational power differentials and stakeholder commitment. Barriers may be greatest where implementation plans contradict system and cultural norms.

Vaginal birth after cesarean section-The world trend and local experience in Taiwan

OBJECTIVE

The trend of increasing cesarean section rates had evoked worldwide attention. Many approaches were introduced to diminish cesarean section rates. Vaginal birth after cesarean section (VBAC) is a route of delivery with diverse agreements. In this study, we try to reveal the world trend in VBAC and our experience of a 10-year period in a medical center in northern Taiwan.

MATERIALS AND METHODS

This is a retrospective study of all women who underwent elective repeat cesarean delivery or trial of labor after cesarean (TOLAC) following primary cesarean delivery by a general obstetrician-gynecologist in the Tamshui Branch of MacKay Memorial Hospital (Taipei, Taiwan) between 2006 and 2015. We excluded cases of preterm labor, two or more cesarean deliveries, and major maternal diseases. We compared the characteristics and outcomes between these groups.

RESULTS

We included 400 women with subsequent pregnancies who underwent elective repeat cesarean delivery or TOLAC during the study period. Among the study population, 112 women were excluded and 11 underwent repeat VBAC. A total of 204 (73.65%) cases underwent elective repeat cesarean delivery and 73 (26.35%) chose TOLAC. The rate of successful VBAC among the women who chose TOLAC was 84.93%.

CONCLUSION

With respect to maternal and fetal safety, and success rates and adverse effects of VBAC, the results of this study are promising and compatible with the global data. It shows that a trial of VBAC can be offered to pregnant women without contraindications with high success rates.

Perinatal and maternal outcomes at term in low-risk pregnancies according to NICE criteria: comparison between a tertiary obstetrical hospital and midwife-attended units

PURPOSE

The aim of this study was to evaluate the perinatal and maternal outcomes at term at a single tertiary, university hospital in women with low-risk pregnancies.

PATIENTS AND METHODS

We performed a retrospective cohort study of women with low-risk pregnancies, who delivered at University Women's Hospital Magdeburg between January 2010 and December 2014. Data were compared with data published by Brocklehurst et al. 2011.

RESULTS

Of the 6052 women investigated, 2014 were classified as low risk according to the NICE criteria and were eligible for analysis. In 94.8%, a spontaneous vertex birth was observed. There were only 2 (0.1%) perinatal complications and 52 (2.5%) maternal complications. Ventouse delivery, forceps delivery, and caesarean sections were performed in 2.5, 1, and 3.1% of the cases, respectively. Episiotomy was performed in 37.7% of women. The third and fourth degree perineal trauma were observed in 0.3% of births investigated. Complications during the third stage of labour and blood transfusions were observed in 0.25 and 0.2%, respectively. In comparison with the births at home, we had lower rate of fetal complications for nulliparous women, but not for multiparous women, lower rate for blood transfusions, third and fourth degree perineal trauma and forceps delivery, and higher rate of spontaneous vertex birth, epidural analgesia, and episiotomy. The rate of vacuum extractions and caesarean sections were similar between both the places of birth.

CONCLUSIONS

The tertiary-level obstetric unit is safe place of birth for women with low-risk pregnancies.

Requests for cesarean deliveries: The politics of labor pain and pain relief in Shanghai, China

Cesarean section rates have risen dramatically in China within the past 25 years, particularly driven by non-medical factors and maternal requests. One major reason women request cesareans is the fear of labor pain, in a country where a minority of women are given any form of pain relief during labor. Drawing upon ethnographic fieldwork and in-depth interviews with 26 postpartum women and 8 providers at a Shanghai district hospital in June and July of 2015, this article elucidates how perceptions of labor pain and the environment of pain relief constructs the cesarean on maternal request. In particular, many women feared labor pain and, in a context without effective pharmacological pain relief or social support during labor, they came to view cesarean sections as a way to negotiate their labor pain. In some cases, women would request cesarean sections during labor as an expression of their pain and a call for a response to their suffering. However, physicians, under recent state policy, deny such requests, particularly as they do not view pain as a reasonable indication for a cesarean birth. This disconnect leads to a mismatch in goals for the experience of birth. To reduce unnecessary C-sections, policy makers should instead address the lack of pain relief during childbirth and develop other means of improving the childbirth experience that may relieve maternal anxiety, such as allowing family members to support the laboring woman and integrating a midwifery model for low-risk births within China's maternal-services system.

Obstetrician gender and delivery mode at a Japanese perinatal center

We examined differences in delivery modes between deliveries managed by female obstetricians and gynecologists (OB/GYNs) and those managed by male OB/GYNs at our hospital. The rate of vacuum extraction/forceps delivery was significantly lower when deliveries were managed by female OB/GYNs. Logistic regression analysis showed that the lower rate of vacuum extraction/forceps delivery was associated with a lower rate of diagnosis of nonreassuring fetal status during the second stage of labor by female OB/GYNs. The rate of cesarean delivery and obstetric outcomes did not differ with the gender of the managing OB/GYN. The increasing number of female OB/GYNs may help increase the rate of maternal satisfaction associated with the decreased rate of instrumental delivery.

Evaluating the 'Focus on Normal Birth and Reducing Caesarean section Rates Rapid Improvement Programme': A mixed method study in England

BACKGROUND

caesarean section plays an important role in ensuring safety of mother and infant but rising rates are not accompanied by measurable improvements in maternal or neonatal mortality or morbidity. The 'Focus on Normal Birth and Reducing Caesarean section Rates Rapid Improvement Programme' was a facilitative initiative developed to promote opportunities for normal birth and reduce caesarean section rates in England.

OBJECTIVE

to evaluate the 'Focus on Normal Birth and Reducing Caesarean section Rates' programme, by assessment of: impact on caesarean section rates, use of service improvements tools and participants׳ perceptions of factors that sustain or hinder work within participating maternity units.

DESIGN

a mixed methods approach included analysis of mode of birth data, web-based questionnaires and in-depth semi-structured telephone interviews.

PARTICIPANTS

twenty Hospital Trusts in England (selected from 68 who applied) took part in the 'Focus on Normal Birth and Reducing Caesarean section Rates Rapid Improvement Programme' initiative. In each hospital Trust, the head of midwifery, an obstetrician, the relevant lead for organisational development, a supervisor of midwives, or a clinical midwife and a service user representative were invited to participate in the independent evaluation.

METHODS

collection and analysis of mode of birth data from 20 participating hospital Trusts, web-based questionnaires administered to key individuals in all 20 Trusts and in-depth semi-structured telephone interviews conducted with key individuals in a sample of six Trusts.

FINDINGS

there was a marginal decline of 0.5% (25.9% from 26.4%) in mean total caesarean section rate in the period 1 January 2009 to 31 January 2010 compared to the baseline period (1 July-31 December 2008). Reduced total caesarean section rates were achieved in eight trusts, all with higher rates at the beginning of the initiative. Features associated with lower caesarean section rates included a shared philosophy prioritising normal birth, clear communication across disciplines and strong leadership at a range of levels, including executive support and clinical leaders within each discipline.

CONCLUSIONS

it is important that the philosophy and organisational context of care are examined to identify potential barriers and facilitative factors.

US nulliparas' perceptions of roles and of the birth experience as predictors of their delivery preferences

OBJECTIVE

to develop a model for understanding predictors of nulliparas' delivery preferences: provider type, setting, mode of delivery and the use/avoidance of pain medication.

DESIGN

a cross-sectional, descriptive, self-administered, web-based survey. The sample was composed of nulliparous women aged 18-40, living in the US and pregnant at 20 or fewer weeks' gestation (n=344). Data were analysed using structural equation modelling.

FINDINGS

women who regard their active participation as effective and essential to the childbearing process are more likely to prefer the care of a midwife, the home as the birth setting, vaginal delivery and the avoidance of pain medication compared to women who see their role as a passive one. When women perceive their provider's role to be more central to the delivery process than their own, they are likely to prefer the care of a physician and the hospital setting. If the provider's role is seen as a collaborative one, women are likelier to prefer midwifery care and planned home birth. The more painful and fearful a woman expects the delivery experience to be, the more likely she is to prefer a caesarean delivery to vaginal birth.

KEY CONCLUSIONS

women's perceptions of (a) their role in pregnancy and delivery, (b) their providers' role in assisting them and (c) the nature of the delivery experience are effective predictors of their delivery preferences.

IMPLICATIONS FOR PRACTICE

providers can help ensure that the informational resources that influence women's perceptions about delivery are factual and evidence-based.

Non-clinical interventions for reducing unnecessary caesarean section

BACKGROUND

Caesarean section rates are steadily increasing globally. The factors contributing to these observed increases are complex. Non-clinical interventions, those applied independent of patient care in a clinical encounter, may have a role in reducing unnecessary caesarean sections.

OBJECTIVES

To evaluate the effectiveness and safety of non-clinical interventions for reducing unnecessary caesarean sections.

SEARCH STRATEGY

We searched the following electronic databases: the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register (29 March 2010), the Cochrane Pregnancy and Childbirth Group Specialised Register (29 March 2010), the Cochrane Central Register of Controlled Trials (The Cochrane Library 2010, Issue 2); MEDLINE (1950 to March 2010); EMBASE (1947 to March 2010) and CINAHL (1982 to March 2010).

SELECTION CRITERIA

We included randomised controlled trials (RCTs), quasi-experimental studies, controlled clinical trials (CCTs), controlled before and after studies (CBAs) with at least two intervention and control sites, and interrupted time series analyses (ITS) where the intervention time was clearly defined and there were at least three data points before and three after the intervention. Studies evaluated non-clinical interventions to reduce unnecessary caesarean section rates. Participants included pregnant women and their families, healthcare providers who work with expectant mothers, communities and advocacy groups.

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed the quality and abstracted data of all eligible studies using a standardised data extraction form, modified from the Cochrane EPOC checklists. We contacted study authors for additional information.

MAIN RESULTS

We included 16 studies in this review.Six studies specifically targeted pregnant women. Two RCTs were shown to be effective in reducing caesarean section rates: a nurse-led relaxation training programme for women with a fear or anxiety of childbirth and birth preparation sessions. However, both RCTs were small in size and targeted younger mothers with their first pregnancies. There is insufficient evidence that prenatal education and support programmes, computer patient decision-aids, decision-aid booklets and intensive group therapy are effective.Ten studies targeted health professionals. Three of these studies were effective in reducing caesarean section rates. A cluster-RCT of guideline implementation with mandatory second opinion resulted in a small, statistically significant reduction in total caesarean section rates (adjusted risk difference (RD) -1.9; 95% confidence interval (CI) -3.8 to -0.1); this reduction was predominately in intrapartum sections. An ITS study of mandatory second opinion and peer review feedback at department meetings found statistically significant results at 48 months for reducing repeat caesarean section rates (change in level was -6.4%; 95% CI -9.7% to -3.1% and change in slope -1.14%; 95% CI -1.9% to -0.3%) but not for total caesarean section rates. A cluster-RCT of guideline implementation with support from local opinion leaders increased the proportion of women with a previous caesarean section being offered a trial of labour (absolute difference 16.8%) and the number who had a vaginal birth (VBAC rates) (absolute difference 13.5%). The P values are, however, not reported due to unit of analysis errors. There was insufficient evidence that audit and feedback, training of public health nurses, insurance reform, external peer review and legislative changes are effective.

AUTHORS' CONCLUSIONS

Implementation of guidelines with mandatory second opinion can lead to a small reduction in caesarean section rates, predominately in intrapartum sections. Peer review, including pre-caesarean consultation, mandatory secondary opinion and postcaesarean surveillance can lead to a reduction in repeat caesarean section rates. Guidelines disseminated with endorsement and support from local opinion leaders may increase the proportion of women with previous caesarean sections being offered a trial of labour in certain settings. Nurse-led relaxation classes and birth preparation classes may reduce caesarean section rates in low-risk pregnancies.

Assessing and understanding quality of care in a labour ward: a pilot study combining clinical and social science perspectives in Gondar, Ethiopia

Ensuring high quality intrapartum care in developing countries is a crucial component of efforts to reduce maternal and neonatal mortality and morbidity. Conceptual frameworks for understanding quality of care have broadened to reflect the complexity of factors affecting quality of health care provision. Yet, the role of social sciences within the assessment and understanding of quality of care in this field has focused primarily on seeking to understand the views and experiences of service users and providers. In this pilot study we aimed to combine clinical and social science perspectives and methods to best assess and understand issues affecting quality of clinical care and to identify priorities for change. Based in one referral hospital in Ethiopia, data collection took place in three phases using a combination of structured and unstructured observations, interviews and a modified nominal group process. This resulted in a thorough and pragmatic methodology. Our results showed high levels of knowledge and compliance with most aspects of good clinical practice, and non-compliance was affected by different, inter-linked, resource constraints. Considering possible changes in terms of resource implications, local stakeholders prioritised five areas for change. Some of these changes would have considerable resources implications whilst others could be made within existing resources. The discussion focuses on implications for informing quality improvement interventions. Improvements will need to address health systems issues, such as supply of key drugs, as well as changes in professional practice to promote the rational use of drugs. Furthermore, the study considers the need to understand broader organizational factors and inter-professional relationships. The potential for greater integration of social science perspectives as part of currently increasing monitoring and evaluation activity around intrapartum care is highlighted.

Obstetrician gender and the likelihood of performing a maternal request for a cesarean delivery

OBJECTIVE

To examine the relationship between obstetrician gender and the likelihood of maternal request for cesarean section (CS) within different healthcare institutions (medical centers, regional hospitals, district hospitals, and obstetric and gynecology clinics).

STUDY DESIGN

Five years of population-based data from Taiwan covering 857,920 singleton deliveries without a clinical indication for a CS were subjected to a multiple logistic regression to examine the association between obstetrician gender and the likelihood of maternal request for a CS.

RESULTS

After adjusting for physician and institutional characteristics, it was found that male obstetricians were more likely to perform a requested CS than female obstetricians in district hospitals (OR=1.53) and clinics (OR=2.26), while obstetrician gender had no discernible associations with the likelihood of a CS upon maternal request in medical centers and regional hospitals.

CONCLUSIONS

While obstetrician gender had the greatest association with delivery mode decisions in the lowest obstetric care units, those associations were diluted in higher-level healthcare institutions.

Outcomes of planned home birth: an integrative review

Current evidence indicates the critical importance of several factors that contribute to improved perinatal outcomes: a facilitating environment at the place of birth, skilled birth attendance, and the continuum of perinatal care for women and newborns. This level of care is often referred to as "first-level" care, and is most readily provided in birthing centers and primary level health facilities. However, there is a body of evidence that has been compiled over the past several decades that addresses the safety of planned home birth, under circumstances that emulate these elements of "first-level" care. These studies demonstrate a remarkable consistency in the generally favorable results of maternal and neonatal outcomes, both over time and among diverse population groups. These outcomes are also favorable when viewed in comparison to various reference groups (birth center births, planned hospital births, and vital statistics). These data should influence policy in support of planned home birth, including policy that endorses building or sustaining a home birth infrastructure in parallel to the efforts to build capacity for facility-based birth. Such public policy would also be in keeping with the fundamental right of women to have choice in childbirth, particularly when options are equally good.

Development of the Optimality Index as a New Approach to Evaluating Outcomes of Maternity Care

Evaluating perinatal outcomes within a framework of normalcy is a new focus of measurement. As maternal and child health clinicians and researchers look to evaluate care practices that are both of high quality and cost-effective, it is important to have measurement tools that assess differences among all women giving birth. The Optimality Index-US shifts the focus from rare adverse events to evidence-based optimal events. This article describes the continuing development of the index and discusses clinical implications for obstetric nurse clinicians.

Unnecessary cesarean delivery in Louisiana: an analysis of birth certificate data

OBJECTIVE

The purpose of this study was to explore the temporal trends and factors that are associated with cesarean deliveries and potentially unnecessary cesarean deliveries.

STUDY DESIGN

The Louisiana birth certificate database was evaluated to identify a total of 57 potential indications/risk factors and maternal demographic factors that are associated with methods of delivery over the period from January 1993 to December 2000. A cesarean delivery without any potential indications/risk factors in the birth certificate was classified as unnecessary.

RESULTS

The primary cesarean delivery rate decreased and the repeat cesarean delivery rate increased significantly during the study period. But neither the absence nor the presence of potential indications/risk factors accounted for these changes. The average potentially unnecessary primary and repeat cesarean deliveries in Louisiana were 17 and 43, respectively, per 100 cesarean deliveries over the years 1993 through 2000.

CONCLUSION

The proportions of potentially unnecessary cesarean deliveries are relatively high in Louisiana. It is important to explore the influence of nonclinical factors on unnecessary cesarean delivery to reduce the cesarean rates.

Saberes e práticas de enfermeiros e obstetras: cooperação e conflito na assistência ao parto

A incorporação crescente de enfermeiros constitui uma das estratégias para melhorar a assistência obstétrica no Brasil, onde o parto é atendido sobretudo por obstetras e em hospitais públicos. Nosso estudo, realizado em duas maternidades do Rio de Janeiro, busca compreender as representações de obstetras e de enfermeiras sobre o trabalho em equipe. Analisa de que forma as dimensões de poder, cooperação e conflito, e autonomia técnica são permeadas por concepções dualistas que influem na organização e qualidade da atenção à parturiente. Os resultados revelam, de um lado, o consenso sobre as vantagens da cooperação profissional para a melhoria da atenção, tendo como premissas a definição de papéis e a valorização de habilidades pessoais. De outro, conflitos vinculados às atribuições profissionais e condutas terapêuticas no parto refletem a percepção dos entrevistados a respeito da autonomia e da hierarquia profissional que relacionam o cuidado obstétrico à "observação objetiva" da parturiente. A magnitude dos conflitos apresenta-se diferenciada segundo o contexto institucional, indicando ser relacionada a limitações advindas de concepções dualistas que separam objetivo/subjetivo, racional/emocional, masculino/feminino, etc.

Forces promoting health insurance coverage of homebirth: a case study in Washington State

The movement of childbirth to the hospital in the early 1900s and the eventual establishments of health insurance reimbursement for hospital birth--but not for homebirth--solidified and reflected physician dominance in the area of obstetrics. Until recently, it was rare that a health insurer or a health maintenance organization (HMO) would cover a homebirth. However, in Washington State the majority of health insurance groups cover homebirths, which are generally attended by licensed midwives. In this context, our research is a case study focused on answering the question: What are the forces promoting the extensive coverage of homebirth by health insurers in Washington State? Data were gathered primarily through fourteen (14) in-depth, audiotaped interviews with key informants in relevant agencies and organizations in the state (i.e., state offices; midwife and other professional associations; and health insurance groups). Results suggest that consumer demand was an important precipitating factor without which changes to health insurance coverage would likely not have been made. Additionally, changes in state policies and professional mobilization on the part of licensed midwives were critical factors facilitating the widespread reimbursement for homebirth. Health care organizations' concerns for cost containment had little impact on this health insurance trend. Our study concludes that jurisdictional openings in the system of professions can be facilitated by a small number of strategically positioned individuals.

[Type of delivery: women's expectations]

This descriptive and exploratory study was carried out through interviews with 221 puerperal women who gave birth in Sao Paulo State public maternities located within the capital. The purposes of the work were: 1. to identify the type of childbirth women expected to have--whether vaginal births or cesareans--and why; 2. to verify to what extent women's expectations corresponded to the type of birth they had; 3. to compare medical indications for c-sections with women's understanding of justifications they were given for this intervention. Data revealed that 74.7% of the women expected to have vaginal births and 25.3% expected to have cesarean sections. Vaginal birth, expected by 165 interviewees, occurred in 66.1% of these cases. Among women who expected having vaginal births, the most mentioned justification was that recuperation afterwards was faster. Among women who expected cesareans, the most mentioned justification was a previous c-section. The justifications presented by 61 women for having been submitted to c-sections did not coincide with medical indications for this intervention in 47.5% of the cases.

Postmodern midwives in Japan: the offspring of modern hospital birth

Although childbirth is fundamentally involved with the issue of women's bodies, it is also involved with such social values as politics, economics, medicine, and other phenomena characteristic of a particular time and culture. In this article I divide Japanese society and childbirth into pre-modern, modern, and postmodern phases, with special emphasis on the postmodern phase. I use the word "postmodern" to denote visible changes in childbirth and midwifery that began to occur around 1990 - changes that distinguish it from modern hospital birth. I conclude that postmodern midwifery is a reaction to and a consequence of modern hospital birth, which failed to satisfy a large number of women's needs. In this sense, postmodern midwifery could rightly be said to be the offspring of modern hospital birth.

Childbirth care-seeking behavior in Chiapas

This study was designed to better understand how women in a developing region choose between the multiple options available to them for birthing. We conducted focused, open-ended ethnographic interviews with 38 nonindigenous, economically marginal women in Chiapas, Mexico. We found that although medical services for birthing were readily available to them, these women most often chose traditional birth attendants (TBAs) for assistance with their births. They expressed a clear preference for TBAs in the case of a normal birth, but viewed medical services as useful for diagnosing and managing problem deliveries and for tubal ligations. They favored TBAs because they valued being able to choose birthing locations and birthing positions and to have relatives present during the birth, all features they must give up for medically attended births in this region.

Measuring outcomes of midwifery care: development of an instrument to assess optimality

Research on the outcomes of midwifery care is hampered by the lack of appropriate instruments that measure both process and outcomes of care in lower risk women. This article describes an effort to adapt an existing measurement instrument focused on the optimal outcomes of care (The Optimality Index-US) to reflect the contemporary style of U.S.-based nurse-midwifery practice. Evidence for content validity of the instrument was derived from literature reports of randomized clinical trials, synthetic reviews, and the clinical consensus of professional reviewers. Eleven perinatal health professionals and consumers, representing disciplines of obstetrics and gynecology, midwifery, epidemiology, and neonatology reviewed the instrument. The instrument was then applied to an existing data set of women who intended to give birth at home (N = 1,286 women) to determine its utility in measuring events in the process and outcome of perinatal health care as managed by nurse-midwives. Results suggest that the tool holds promise for use in outcomes studies of U.S. perinatal care. Further testing of the instrument among diverse multicultural population groups, with various providers, and in diverse birth settings is warranted.

Methodologies analysing individual practice in health care: a systematic review

AIM OF THE REVIEW

The aim of the systematic review was to identify, explore and evaluate the current level of knowledge of methodologies used in comparative analyses of the individual practice of doctors, nurses and midwives.

RATIONALE

The question of how roles and responsibilities might be shared differently between professional groups in order to promote improved, cost-effective health care requires a systematic analysis of existing roles and practice. To do this effectively, knowledge of the methodologies available for such an analysis is essential.

METHODS

A systematic review of the literature published since 1989 comparing the practice of doctors, nurses and midwives was undertaken.

FINDINGS

The findings are presented in tabular format and include the following categories of published methodologies: experimental/quasi-experimental; descriptive/nonexperimental and qualitative studies. The discussion centres on a critique of quantitative methodologies used to analyse individual practice in relation to role substitution and diversification. The potential contribution of qualitative methodologies in the analysis of individual practice is discussed.

CONCLUSIONS

The authors conclude that the current level of knowledge is biased towards quantitative research. It is argued that the assessment of health care roles and responsibilities would be well served by a more balanced approach that recognizes the strengths of both quantitative and qualitative work.

Factors associated with Army obstetricians-gynecologists' practice of HIV prevention education during routine gynecologic care

The authors evaluate obstetricians-gynecologists' (OB-GYNs') anxiety about clinical uncertainty and patient, physician, and organizational factors associated with their selection of HIV-related educational activities for high-risk and low-risk written case simulations. A total of 117 U.S. Army OB-GYNs completed a mailed, anonymous questionnaire. Overall, informants were much less likely to educate in response to the low-risk simulation; however, more informants who were anxious about uncertainty were more likely to do so in a model that included supportive institutional policies, willingness to educate despite patient barriers, and comfort with the topic. OB-GYNs were more likely to educate in response to the high-risk simulation given greater willingness to discuss HIV despite organizational barriers, supportive policies, and comfort. Findings suggest a need to better understand the role that anxiety about uncertainty plays in HIV prevention and the need to promote organizational policies that support and remove barriers to clinically based education.

Physician gender and cesarean sections

BACKGROUND

Among consumers insurers, and providers there is pervasive concern regarding the high incidence of cesarean section delivery. To date, attempts to reduce these rates have focused on the clinical behavior of providers resulting in only minimal changes. Therefore, non-medical variables must be investigated as potential explanatory factors for the decision to perform cesarean delivery.

METHODS

Data were collected on clinical and non-clinical factors for obstetrician-gynecologists delivering at Yale-New Haven Medical Center to measure the impact of these factors on the performance of cesarean sections. Specifically, variation in patient demographic, ante- and intra-partum risk variables, practice setting, and doctor-specific characteristics were examined. Using contingency table and logistic regression analyses the contribution of selected factors was evaluated.

RESULTS

Multivariate modeling revealed that male physicians were significantly more likely than their female colleagues to perform cesarean section. This relationship was particularly strong in the university practice setting.

CONCLUSIONS

Efforts to reduce the incidence of cesarean section need to focus on the continuing education of health care providers and the delineation of non-clinical factors as essential elements in the election of specific clinical therapies.

Intrapartum nursing care: a case study of supportive interventions and ethical conflicts

BACKGROUND

Studies have shown that one-to-one labor support is associated with a reduced rate of operative births, and with long-term improvements of parenting and breastfeeding rates. Labor support by nurses may reduce the cesarean birth rate, but this has not been adequately studied. No one knows which labor support strategies nurses use, if they are effective, and how they work.

METHODS

This pilot study used the qualitative techniques of observation and an audiotaped interview with an expert intrapartum nurse to describe labor support techniques and strategies to enhance labor progress and prevent cesarean births.

RESULTS

The narrative revealed three major themes. The first theme, "the nurse's approaches to labor," included three subcategories: "following the mother's body," "hastening and controlling labor," and "labor support techniques." The second and third major themes, "ethical dilemmas: an unwilling partnership" and "nurse-physician conflict," were unanticipated. Labor support practices were limited by some physician practices. Inappropriate physician practice created ethical dilemmas for the nurse and impeded labor support interventions.

CONCLUSIONS

Intrapartum nursing care reflected both a medical model of controlling and hastening birth, as well as a supportive, nurturing, and empowering model of practice that used independent clinical judgments and advocacy. Questionable medical care entangled the nurse in these practices and created moral dilemmas and nurse-physician conflicts. The nurse used various strategies to promote the wishes and welfare of the laboring mother.

Interspecialty differences in the obstetric care of low-risk women

OBJECTIVES

This study examined differences among obstetricians, family physicians, and certified nurse-midwives in the patterns of obstetric care provided to low-risk patients.

METHODS

For a random sample of Washington State obstetrician-gynecologists, family physicians, and certified nurse-midwives, records of a random sample of their low-risk patients beginning care between September 1, 1988, and August 31, 1989, were abstracted.

RESULTS

Certified nurse-midwives were less likely to use continuous electronic fetal monitoring and had lower rates of labor induction or augmentation than physicians. Certified nurse-midwives also were less likely than physicians to use epidural anesthesia. The cesarean section rate for patients of certified nurse-midwives was 8.8% vs 13.6% for obstetricians and 15.1% for family physicians. Certified nurse-midwives used 12.2% fewer resources. There was little difference between the practice patterns of obstetricians and family physicians.

CONCLUSIONS

The low-risk patients of certified nurse-midwives in Washington State received fewer obstetrical interventions than similar patients cared for by obstetrician-gynecologists or family physicians. These differences are associated with lower cesarean section rates and less resource use.

The Cochrane pregnancy and childbirth database. Implications for perinatal care policy and practice in the United States

The Cochrane Pregnancy and Childbirth Database (CCPC) is the most sophisticated realization of the meta-analytic potential within the health fields. At the core of this ongoing collaborative international project are about 600 systematic reviews of the effectiveness of specific forms of perinatal care, which have been created from a registry of clinical trials. The scale and quality of information available through CCPC are unprecedented. An examination of implications of CCPC suggests that many far-reaching changes in perinatal policy and practice are indicated. CCPC has become a model for similar work that is being organized in many other clinical areas under the umbrella of the pan-clinical Cochrane Collaboration, and the experience and implications of CCPC will be of interest to many working in other areas. The implications of these ambitious meta-analytic projects are profound; the degree to which they will be realized is less certain.

Explaining excessive rates of cesareans and other childbirth interventions: contributions from contemporary theories of gender and psychosocial development

The current rate of cesarean sections in the U.S. is too high. Numerous mothers and babies are being placed at unnecessary risk of medical, behavioral and psychological complications. The problem has proven resistant to solution on a large scale, despite serious efforts on the part of a variety of individuals and groups. This paper considers reports on the interactions between obstetricians and mothers in labor in light of findings and theory in the areas of gender and psychosocial development. Examination of processes and standards of care in light of these findings and theory leads to the conclusion that the present model of obstetric services is consistent with a masculine style, and offers far less than optimal care for women. In fact, the gender-inappropriate elements of the model itself probably contribute to the excessive rates of interventions in labor. Social, political and historical factors are seen to support the obstetric model as is, leading to some pessimism about the possibility that the model could be modified sufficiently without major social change. The obstetric model is compared briefly with the more gender appropriate model of care provided by midwives.

Medically unnecessary cesarean section births: introduction to a symposium

Between 1965 and 1986, the United States cesarean section rate increased from 4.5 to 24.1%. Increasingly, childbearing women and their advocates, along with many others, have recognized that a large proportion of cesareans confers a broad array of risks without providing any medical benefit. A growing literature examines the diverse causes of medically unnecessary cesareans and the diverse effects of surgical birth on women, infants, and families. Various programs and policies have been proposed or implemented to reduce cesarean rates. In recent decades, many other nations have also experienced a sharply escalating cesarean section rate. It is reasonable to conclude that a largely uncontrolled international pandemic of medically unnecessary cesarean births is occurring. The level of political, analytic, and programmatic activity that has occurred in the U.S. regarding medically unnecessary surgical births does not seem to be paralleled in other nations with sharply escalating rates. This symposium was organized with the objective of presenting the U.S. experience with various dimensions of the problem of medically unnecessary cesareans to an international audience. Although preliminary and inadequate, it is hoped that this experience will encourage policy leaders and investigators throughout the world to recognize and address the problem of run-away cesarean section births. The first section of this introduction summarizes the U.S. experience with medically unnecessary cesareans from the perspective of trends, causes, consequences, and solutions. The second section covers the same topics, presenting selected material from various other nations throughout the world. In the course of these overviews, I introduce the symposium's seven contributions, most of which focus on circumstances in the U.S.
