Inconsistent evidence: analysis of six national guidelines for vaginal birth after cesarean section

Antenatal education - Putting research into practice: A guideline review

PROBLEM

Antenatal care guidelines used in Australia are inconsistent in their recommendations for childbirth and parenting education (CBPE) classes for preparation of women and parents for pregnancy, childbirth, and early parenting.

BACKGROUND

Clinical practice guidelines in maternity care are developed to assist healthcare practitioners and consumers to make decisions about appropriate care. The benefit of such guidelines relies on the translation and quality of the evidence contained within them. In the context of antenatal care guidelines, there is a potential evidence-practice gap with regard to CBPE.

AIMS

This review aims to appraise the quality of Australian antenatal care guidelines in their recommendations for CBPE for women and partners.

METHODS

Publicly available Australian antenatal care guidelines were identified including local health district websites and professional organisations pertaining to maternity care. Guidelines were reviewed independently, and the quality was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool.

FINDINGS

Five guidelines were included in the review and appraised using AGREE II. With the exception of the Department of Health Pregnancy Care Guidelines, guidelines scored poorly across all six domains. When appraised according to specific CBPE recommendations for rigour of development, presentation, and applicability; all guidelines received low scores.

DISCUSSION

Prenatal services remain largely unregulated across the board, with no systematic approach to make recommendations for CBPE and guidelines lacking in rigour with regard to CBPE.

CONCLUSION

Within the guidelines reviewed there was a lack of evidence-based recommendations provided for educators or consumers regarding childbirth and parenting education.

Decision-making experiences and the need for decision aids in women considering vaginal birth after cesarean: A qualitative meta-synthesis

AIMS

This study aims to comprehensively explore the decision-making requirements of women contemplating vaginal birth after cesarean (VBAC).

DESIGN & METHODS

A meta-synthesis approach was employed for this study. Using an integrative methodology, we conducted a systematic assessment of women's experiences and needs related to VBAC decision-making. A comprehensive search was conducted across The Cochrane Library, PubMed, EMBASE, Ovid Medline, SCOPUS, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, and Wan Fang databases to identify pertinent studies between 2000 and 2022. Furthermore, the reference lists of the included studies were thoroughly examined.

RESULTS

Fifteen studies were incorporated, from which seven themes emerged: emotional changes, preference for vaginal birth, unmet information needs, influences on decision-making, decision-making autonomy, aligning information provision with decision-support needs, and the requirement for support systems. Two primary syntheses were constructed on the decision-making process and the need for decision-making aids, respectively.

CONCLUSION

Women opting for VBAC experienced emotional shifts during their decision-making process in pregnancy. There remains a need for an enhanced decision-making tool to guide them in their choice. Recommendations for implementation in VBAC decision aids include facilitating women's involvement in decision-making, satisfying their information needs, and delivering appropriate emotional support.

Neonatal outcomes associated with mode of subsequent birth after a previous caesarean section in a first pregnancy: a Swedish population-based register study between 1999 and 2015

OBJECTIVE

To investigate neonatal outcomes within 28 days in the subsequent birth in women who gave birth to their first baby by caesarean section (CS).

DESIGN AND SETTING

National retrospective population-based register study. A cohort of 94 451 neonates who were born in Sweden between 1999 and 2015 as a second child to a mother who had her first birth by emergency or planned caesarean.

METHODS

Data were retrieved from the national registers held by Statistics Sweden and the National Board of Health and Welfare. Logistic regression was used to calculate unadjusted and adjusted ORs (aOR) with 95% CIs for each outcome.

MAIN OUTCOME MEASURES

Neonatal infection, neonatal asphyxia/respiratory distress, neonatal hospital care and neonatal death within 28 days.

RESULTS

Emergency CS and instrumental vaginal birth were associated with a doubled risk of neonatal infection (aOR 2.0) and planned CS with a decreased risk (aOR 0.7) compared with spontaneous vaginal birth. Compared with spontaneous vaginal birth, an increased risk of birth asphyxia and/or respiratory distress was identified with all other modes of birth (aOR 2.2-3.2). Emergency CS and instrumental vaginal birth, but not planned CS, were associated with neonatal hospital care (aOR 1.8 and 1.7) and an increased mortality rate during the neonatal period (aOR 2.9 and 3.2), compared with spontaneous vaginal birth.

CONCLUSIONS

In childbirth following a previous birth by CS, spontaneous vaginal birth appears to confer better neonatal outcomes within 28 days after birth overall than other modes of birth.

Postpartum care indications and methodological quality:a systematic review of guidelines

Background

The coverage of postpartum care is not ideal, and has not been used very well due to not enough attention being paid to the puerperal women and newborns, especially in developing countries. Practice guidelines on postpartum care provide beneficial practice guidance and help to reduce maternal mortality. However, little is known about the credibility and consistency of those guidelines. This systematic review was conducted to summarize main postpartum care indications and appraise methodological quality of guidelines.

Methods

Seven literature databases and guideline development institutions and organizations of obstetrics and maternity care were searched. Two reviewers independently assessed guideline quality using the AGREE II instrument, and synthesized consistent and non-consistent recommendations using the content analysis approach.

Results

Twenty-nine guidelines were included and a total of eight postpartum care indications were identified. Most guidelines focused on care indications and interventions including exclusive breastfeeding, maternal nutrition, home visit, infant or newborn care and sexuality, contraception, and birth spacing. However, indications such as pain or weight management, pelvic floor muscle training, abdominal rehabilitation, and mental health got less attention. Additionally, the overall quality of all involving postpartum care guidelines is relatively good and acceptable.

Conclusions

Guidelines developed by NICE, RANO, and WHO indicated higher methodological quality. For postpartum care indications, most guidelines are incomplete. Variation in practice guidelines for postpartum care recommendations exists. In the future, implementation research into shared decision-making, as well as further high-quality research to broaden the evidence base for postpartum care indications is recommended.

Breech presentation management: A critical review of leading clinical practice guidelines

PROBLEM

Clinical practice guidelines are designed to guide clinicians and consumers of maternity services in clinical decision making, but recommendations are often consensus based and differ greatly between leading organisations.

BACKGROUND

Breech birth is a divisive clinical issue, however vaginal breech births continue to occur despite a globally high caesarean section rate for breech presenting fetuses. Inconsistencies are known to exist between clinical practice guidelines relating to the management of breech presentation.

AIM

The aim of this review was to critically evaluate and compare leading obstetric clinical practice guidelines related to the management of breech presenting fetuses.

METHODS

Leading obstetric guidelines were purposively obtained for review. Analysis was conducted using the International Centre for Allied Health Evidence (iCAHE) Guideline Quality Checklist and reviewing the content of each guideline.

FINDINGS

Antenatal care recommendations and indications for Caesarean Section were relatively consistent between clinical guidelines. However, several inconsistencies were found among the other recommendations in terms of birth mode counselling, intrapartum management and the basis for recommendations.

DISCUSSION

Inconsistencies noted in the clinical practice guidelines have the potential to cause issues related to valid consent and create confusion among clinicians and maternity consumers.

CONCLUSION

Clinical practice guidelines, which focus on the risks of a Vaginal Breech Birth without also discussing the risks of a Caesarean Section when a breech presentation is diagnosed, has the potential to sway clinician attitudes and impact birth mode decision-making in maternity consumers. To respect pregnant women's autonomy and fulfil the legal requirements of consent, clinicians should provide balanced counselling.

A systematic scoping review of clinical indications for induction of labour

BACKGROUND

The proportion of women undergoing induction of labour (IOL) has risen in recent decades, with significant variation within countries and between hospitals. The aim of this study was to review research supporting indications for IOL and determine which indications are supported by evidence and where knowledge gaps exist.

METHODS

A systematic scoping review of quantitative studies of common indications for IOL. For each indication, we included systematic reviews/meta-analyses, randomised controlled trials (RCTs), cohort studies and case control studies that compared maternal and neonatal outcomes for different modes or timing of birth. Studies were identified via the databases PubMed, Maternity and Infant Care, CINAHL, EMBASE, and ClinicalTrials.gov from between April 2008 and November 2019, and also from reference lists of included studies. We identified 2554 abstracts and reviewed 300 full text articles. The quality of included studies was assessed using the RoB 2.0, the ROBINS-I and the ROBIN tool.

RESULTS

68 studies were included which related to post-term pregnancy (15), hypertension/pre-eclampsia (15), diabetes (9), prelabour rupture of membranes (5), twin pregnancy (5), suspected fetal compromise (4), maternal elevated body mass index (BMI) (4), intrahepatic cholestasis of pregnancy (3), suspected macrosomia (3), fetal gastroschisis (2), maternal age (2), and maternal cardiac disease (1). Available evidence supports IOL for women with post-term pregnancy, although the evidence is weak regarding the timing (41 versus 42 weeks), and for women with hypertension/preeclampsia in terms of improved maternal outcomes. For women with preterm premature rupture of membranes (24-37 weeks), high-quality evidence supports expectant management rather than IOL/early birth. Evidence is weakly supportive for IOL in women with term rupture of membranes. For all other indications, there were conflicting findings and/or insufficient power to provide definitive evidence.

CONCLUSIONS

While for some indications, IOL is clearly recommended, a number of common indications for IOL do not have strong supporting evidence. Overall, few RCTs have evaluated the various indications for IOL. For conditions where clinical equipoise regarding timing of birth may still exist, such as suspected macrosomia and elevated BMI, researchers and funding agencies should prioritise studies of sufficient power that can provide quality evidence to guide care in these situations.

Factors associated with successful vaginal birth after a cesarean section: a systematic review and meta-analysis

BACKGROUND

Evidence for the relationship between maternal and perinatal factors and the success of vaginal birth after cesarean section (VBAC) is conflicting. We aimed to systematically analyze published data on maternal and fetal factors for successful VBAC.

METHODS

A comprehensive search of Medline, Embase, and the Cumulative Index to Nursing and Allied Health Literature, from each database's inception to March 16, 2018. Observational studies, identifying women with a trial of labor after one previous low-transverse cesarean section were included. Two reviewers independently abstracted the data. Meta-analysis was performed using the random-effects model. Risk of bias was assessed by the Newcastle-Ottawa Scale.

RESULTS

We included 94 eligible observational studies (239,006 pregnant women with 163,502 VBAC). Factors were associated with successful VBAC with the following odds ratios (OR;95%CI): age (0.92;0.86-0.98), obesity (0.50;0.39-0.64), diabetes (0.50;0.42-0.60), hypertensive disorders complicating pregnancy (HDCP) (0.54;0.44-0.67), Bishop score (3.77;2.17-6.53), labor induction (0.58;0.50-0.67), macrosomia (0.56;0.50-0.64), white race (1.39;1.26-1.54), previous vaginal birth before cesarean section (3.14;2.62-3.77), previous VBAC (4.71;4.33-5.12), the indications for the previous cesarean section (cephalopelvic disproportion (0.54;0.36-0.80), dystocia or failure to progress (0.54;0.41-0.70), failed induction (0.56;0.37-0.85), and fetal malpresentation (1.66;1.38-2.01)). Adjusted ORs were similar.

CONCLUSIONS

Diabetes, HDCP, Bishop score, labor induction, macrosomia, age, obesity, previous vaginal birth, and the indications for the previous CS should be considered as the factors affecting the success of VBAC.

Induction of labour indications and timing: A systematic analysis of clinical guidelines

BACKGROUND

There is widespread and some unexplained variation in induction of labour rates between hospitals. Some practice variation may stem from variability in clinical guidelines. This review aimed to identify to what extent induction of labour guidelines provide consistent recommendations in relation to reasons for, and timing of, induction of labour and ascertain whether inconsistencies can be explained by variability guideline quality.

METHOD

We conducted a systematic search of national and international English-language guidelines published between 2008 and 2018. General induction of labour guidelines and condition-specific guidelines containing induction of labour recommendations were searched. Guidelines were reviewed and extracted independently by two reviewers. Guideline quality was assessed using the Appraisal of Guidelines for Research and Evaluation II Instrument.

FINDINGS

Forty nine guidelines of varying quality were included. Indications where guidelines had mostly consistent advice included prolonged pregnancy (induction between 41 and 42 weeks), preterm premature rupture of membranes, and term preeclampsia (induction when preeclampsia diagnosed ≥37 weeks). Guidelines were also consistent in agreeing on decreased fetal movements and oligohydramnios as valid indications for induction, although timing recommendations were absent or inconsistent. Common indications where there was little consensus on validity and/or timing of induction included gestational diabetes, fetal macrosomia, elevated maternal body mass index, and twin pregnancy.

CONCLUSION

Substantial variation in clinical practice guidelines for indications for induction exists. As guidelines rated of similar quality presented conflicting recommendations, guideline variability was not explained by guideline quality. Guideline variability may partly account for unexplained variation in induction of labour rates.

Indications for, and timing of, planned caesarean section: A systematic analysis of clinical guidelines

BACKGROUND

There has been a worldwide rise in planned caesarean sections over recent decades, with significant variations in practice between hospitals and countries. Guidelines are known to influence clinical decision-making and, potentially, unwarranted clinical variation. The aim of this study was to review guidelines for recommendations in relation to the timing and indications for planned caesarean section as well as recommendations around the process of decision-making.

METHOD

A systematic search of national and international English-language guidelines published between 2008 and 2018 was undertaken. Guidelines were reviewed, assessed in terms of quality and extracted independently by two reviewers.

FINDINGS

In total, 49 guidelines of varying quality were included. There was consistency between the guidelines in potential indications for caesarean section, although guidelines vary in terms of the level of detail. There was substantial variation in timing of birth, for example recommended timing of caesarean section for women with uncomplicated placenta praevia is between 36 and 39weeks depending on the guideline. Only 11 guidelines provided detailed guidance on shared decision-making. In general, national-level guidelines from Australia, and overseas, received higher quality ratings than regional guidelines.

CONCLUSION

The majority of guidelines, regardless of their quality, provide very limited information to guide shared decision-making or the timing of planned caesarean section, two of the most vital aspects of guidance. National guidelines were generally of better quality than regional ones, suggesting these should be used as a template where possible and emphasis placed on improving national guidelines and minimising intra-country, regional, variability of guidelines.

An evaluation of the objective quality and perceived usefulness of maternity clinical practice guidelines at a tertiary maternity unit

BACKGROUND

Compliance with maternity clinical practice guidelines developed by National Women's Health has been found to be low at audit.

OBJECTIVE

To explore the reasons for poor compliance with maternity guidelines by evaluating the quality of a sample of National Women's Health guidelines using a validated instrument and assessing local guideline users' perceptions of and attitudes toward guidelines.

DESIGN

Five independent reviewers evaluated the quality of 10 purposively selected guidelines for adherence to the Appraisal of Guidelines Research & Evaluation (AGREE) II instrument standards. A self-administered questionnaire for staff was undertaken regarding views of and barriers to guideline use.

RESULTS

None of the guidelines attained a score over 50% for the following domains: stakeholder involvement, rigour of development, applicability, editorial independence. The highest scoring domain was clarity of presentation (mean 69%). All guidelines scored the minimum possible for editorial independence. Survey respondents had positive attitudes toward guidelines, believed that their use could improve quality of care within the service, and felt that encouragement from senior staff members and peers would encourage their use. Accessibility was the most commonly cited of many barriers identified.

CONCLUSION

The National Women's Health guidelines evaluated in this study cannot be considered to be high quality, and could be improved by reporting on methodology of the development process. Although poor guideline development may contribute to failure of the local maternity guidelines, it appears that accessibility is a major barrier to their use and implementation.

Review and appraisal of guidelines for the management of asthma during pregnancy

BACKGROUND

Asthma affects 12.7% of pregnancies in Australia. Poorly controlled asthma is associated with increased maternal and infant morbidity and mortality. Optimal antenatal management of asthma during pregnancy has the potential to reduce complications relating to asthma. Evidence-based clinical practice guidelines help to translate health research findings into practice and when implemented can improve health outcomes. National and International guidelines currently provide recommendations for optimal asthma care in pregnancy.

AIM

To appraise the existing asthma in pregnancy guidelines with respect to their evidence for recommendations, consistency of recommendations and appropriateness for clinical practice.

METHOD

The Appraisal of Guidelines for Research and Evaluation (AGREE II) tool was used to appraise four English language asthma in pregnancy guidelines, published or updated between 2007 and 2016. The recommendations, range and level of evidence was analysed.

RESULTS

Two of the four guidelines scored highly in most domains of the appraisal. Many of the recommendations made in the appraised guidelines were consistent. Due to the lack of randomised controlled trials involving pregnant women with asthma, most recommendations were evidenced by consensus and expert opinion rather than high quality meta-analysis, systematic reviews of randomised controlled trials.

CONCLUSION

The recommended antenatal asthma management was generally consistent among the guidelines but lacked clarity in some areas which then leave them open to interpretation. More randomised controlled trials involving pregnant women with asthma are required to fortify the recommendations made and asthma management guidelines should be included in Australian Antenatal Care Guidelines as they currently are not.

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.

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

PROBLEM

One of the greatest contributors to the overall caesarean section rate is elective repeat caesarean section.

BACKGROUND

Decisions around mode of birth are often complex for women and influenced by the views of the doctors and midwives who care for and counsel women. Women may be more likely to choose a repeat elective caesarean section (CS) if their health care providers lack skills and confidence in supporting vaginal birth after caesarean section (VBAC).

AIM

To explore the views and experiences of providers in caring for women considering VBAC, in particular the decision-making processes and the communication of risk and safety to women.

METHODS

A descriptive interpretive method was utilised. Four focus groups with doctors and midwives were conducted.

FINDINGS

The central themes were: 'developing trust', 'navigating the system' and 'optimising support'. The impact of past professional experiences; the critical importance of continuity of carer and positive relationships; the ability to weigh up risks versus benefits; and the language used were all important elements. The role of policy and guidelines on providing standardised care for women who had a previous CS was also highlighted.

CONCLUSION

Midwives and doctors in this study were positively oriented towards assisting and supporting women to attempt a VBAC. Care providers considered that women who have experienced a prior CS need access to midwifery continuity of care with a focus on support, information-sharing and effective communication.

A critical review of vaginal birth rates after a primary Caesarean in Queensland hospitals

INTRODUCTION

For women with a lower uterine incision without indication for repeat Caesarean section (CS), vaginal birth for their next pregnancy is a safe option. Although these women should be encouraged to consider vaginal birth after a Caesarean section (VBAC) it is not consistently supported in practice. There is relatively little information on the extent to which maternal preference, birthing decisions and outcomes match best available evidence.

AIM

To describe current VBAC rates for women in Queensland, Australia and compare this to safe, achievable VBAC rates reported in national and international studies.

METHOD

Perinatal data from 2004 to 2011 were reviewed to determine current VBAC rates following a primary CS for women birthing in Queensland. These were compared with VBAC rates reported in the literature.

RESULTS

Queensland has a high overall CS rate and high repeat CS rate compared with the national average. In 2010, Queensland VBAC rates for next birth following primary CS were 14% (range 13-21% public sector, 7-11% private hospitals). This is substantially lower than achievable Australian rates of 24% and international rates.

CONCLUSION

Low VBAC rates reflect low numbers of women commencing labour in a pregnancy subsequent to a primary CS. There is unexplained variation in VBAC rates between maternity facilities. Clinical reviews to support evidence-based practice are warranted.

Interventions for supporting pregnant women's decision-making about mode of birth after a caesarean

BACKGROUND

Pregnant women who have previously had a caesarean birth and who have no contraindication for vaginal birth after caesarean (VBAC) may need to decide whether to choose between a repeat caesarean birth or to commence labour with the intention of achieving a VBAC. Women need information about their options and interventions designed to support decision-making may be helpful. Decision support interventions can be implemented independently, or shared with health professionals during clinical encounters or used in mediated social encounters with others, such as telephone decision coaching services. Decision support interventions can include decision aids, one-on-one counselling, group information or support sessions and decision protocols or algorithms. This review considers any decision support intervention for pregnant women making birth choices after a previous caesarean birth.

OBJECTIVES

To examine the effectiveness of interventions to support decision-making about vaginal birth after a caesarean birth.Secondary objectives are to identify issues related to the acceptability of any interventions to parents and the feasibility of their implementation.

SEARCH METHODS

We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2013), Current Controlled Trials (22 July 2013), the WHO International Clinical Trials Registry Platform Search Portal (ICTRP) (22 July 2013) and reference lists of retrieved articles. We also conducted citation searches of included studies to identify possible concurrent qualitative studies.

SELECTION CRITERIA

All published, unpublished, and ongoing randomised controlled trials (RCTs) and quasi-randomised trials with reported data of any intervention designed to support pregnant women who have previously had a caesarean birth make decisions about their options for birth. Studies using a cluster-randomised design were eligible for inclusion but none were identified. Studies using a cross-over design were not eligible for inclusion. Studies published in abstract form only would have been eligible for inclusion if data were able to be extracted.

DATA COLLECTION AND ANALYSIS

Two review authors independently applied the selection criteria and carried out data extraction and quality assessment of studies. Data were checked for accuracy. We contacted authors of included trials for additional information. All included interventions were classified as independent, shared or mediated decision supports. Consensus was obtained for classifications. Verification of the final list of included studies was undertaken by three review authors.

MAIN RESULTS

Three randomised controlled trials involving 2270 women from high-income countries were eligible for inclusion in the review. Outcomes were reported for 1280 infants in one study. The interventions assessed in the trials were designed to be used either independently by women or mediated through the involvement of independent support. No studies looked at shared decision supports, that is, interventions designed to facilitate shared decision-making with health professionals during clinical encounters.We found no difference in planned mode of birth: VBAC (risk ratio (RR) 1.03, 95% confidence interval (CI) 0.97 to 1.10; I² = 0%) or caesarean birth (RR 0.96, 95% CI 0.84 to 1.10; I² = 0%). The proportion of women unsure about preference did not change (RR 0.87, 95% CI 0.62 to 1.20; I² = 0%).There was no difference in adverse outcomes reported between intervention and control groups (one trial, 1275 women/1280 babies): permanent (RR 0.66, 95% CI 0.32 to 1.36); severe (RR 1.02, 95% CI 0.77 to 1.36); unclear (0.66, 95% CI 0.27, 1.61). Overall, 64.8% of those indicating preference for VBAC achieved it, while 97.1% of those planning caesarean birth achieved this mode of birth. We found no difference in the proportion of women achieving congruence between preferred and actual mode of birth (RR 1.02, 95% CI 0.96 to 1.07) (three trials, 1921 women).More women had caesarean births (57.3%), including 535 women where it was unplanned (42.6% all caesarean deliveries and 24.4% all births). We found no difference in actual mode of birth between groups, (average RR 0.97, 95% CI 0.89 to 1.06) (three trials, 2190 women).Decisional conflict about preferred mode of birth was lower (less uncertainty) for women with decisional support (standardised mean difference (SMD) -0.25, 95% CI -0.47 to -0.02; two trials, 787 women; I² = 48%). There was also a significant increase in knowledge among women with decision support compared with those in the control group (SMD 0.74, 95% CI 0.46 to 1.03; two trials, 787 women; I² = 65%). However, there was considerable heterogeneity between the two studies contributing to this outcome ( I² = 65%) and attrition was greater than 15 per cent and the evidence for this outcome is considered to be moderate quality only. There was no difference in satisfaction between women with decision support and those without it (SMD 0.06, 95% CI -0.09 to 0.20; two trials, 797 women; I² = 0%). No study assessed decisional regret or whether women's information needs were met.Qualitative data gathered in interviews with women and health professionals provided information about acceptability of the decision support and its feasibility of implementation. While women liked the decision support there was concern among health professionals about their impact on their time and workload.

AUTHORS' CONCLUSIONS

Evidence is limited to independent and mediated decision supports. Research is needed on shared decision support interventions for women considering mode of birth in a pregnancy after a caesarean birth to use with their care providers.

Does continuity of care impact decision making in the next birth after a caesarean section (VBAC)? a randomised controlled trial

Background

Caesarean section (CS) has short and long-term health effects for both the woman and her baby. One of the greatest contributors to the CS rate is elective repeat CS. Vaginal birth after caesarean (VBAC) is an option for many women; despite this the proportion of women attempting VBAC remains low. Potentially the relationship that women have with their healthcare professional may have a major influence on the uptake of VBAC. Models of service delivery, which enable an individual approach to care, may make a difference to the uptake of VBAC. Midwifery continuity of care could be an effective model to encourage and support women to choose VBAC.

Methods/Design

A randomised, controlled trial will be undertaken. Eligible pregnant women, whose most recent previous birth was by lower-segment CS, will be randomly allocated 1:1 to an intervention group or control group. The intervention provides midwifery continuity of care to women through pregnancy, labour, birth and early postnatal care. The control group will receive standard hospital care from different midwives through pregnancy, labour, birth and early postnatal care. Both groups will receive an obstetric consultation during pregnancy and at any other time if required. Clinical care will follow the same guidelines in both groups.

Discussion

This study will determine whether midwifery continuity of care influences the decision to attempt a VBAC and impacts on mode of birth, maternal experiences with care and the health of the neonate. Outcomes from this study might influence the way maternity care is provided to this group of women and thus impact on the CS rate. This information will provide high level evidence to policy makers, health service managers and practitioners who are working towards addressing the increased rate of CS.

Trial registration

This trial is registered with the Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12611001214921

The effect of malpractice claims on the use of caesarean section

Malpractice fears are believed to influence various aspects of obstetrical practice. They seem to have contributed in small part to the rising primary caesarean section rate, but have also played a considerable role in the downtrend in vaginal birth after caesarean statistics. The rising vaginal birth after caesarean section rate between 1981 and 1995 was interrupted by a spate of lawsuits associated with broadened indications for vaginal birth after caesarean section in conjunction with requirements for immediate clinician availability. These factors dramatically reduced the availability of hospitals and clinicians willing to offer vaginal birth after caesarean section. This reversal, however, has not diminished the demand for vaginal birth after caesarean section from various stakeholders in the name of patient autonomy, clinician beneficence and optimal care. Nevertheless, as long as stringent requirements remain for clinician attendance during vaginal birth after caesarean section, and as long as the spectre of preventable error and the lingering dread of lawsuits retain their hold on obstetrical practice, caesarean section trends are unlikely to change.

'Groping through the fog': a metasynthesis of women's experiences on VBAC (Vaginal birth after Caesarean section)

BACKGROUND

Vaginal birth after Caesarean section (VBAC) is a relevant question for a large number of women due to the internationally rising Caesarean section (CS) rate. There is a great deal of research based on quantitative studies but few qualitative studies about women's experiences.

METHOD

A metasynthesis based on the interpretative meta ethnography method was conducted. The inclusion criterion was peer-review qualitative articles from different disciplines about women's experiences of VBAC. Eleven articles were checked for quality, and eight articles were included in the synthesis.

RESULTS

The included studies were from Australia (four), UK (three), and US (one), and studied women's experience in relation to different aspects of VBAC; decision-making whether to give birth vaginally, the influence of health professionals on decision-making, reason for trying a vaginal birth, experiences when choosing VBAC, experiences of giving birth vaginally, and giving birth with CS when preferring VBAC. The main results are presented with the metaphor groping through the fog; for the women the issue of VBAC is like being in a fog, where decision-making and information from the health care system and professionals, both during pregnancy and the birth, is unclear and contrasting. The results are further presented with four themes: 'to be involved in decision about mode of delivery is difficult but important,' 'vaginal birth has several positive aspects mainly described by women,' 'vaginal birth after CS is a risky project,' and 'own strong responsibility for giving birth vaginally'.

CONCLUSION

In order to promote VBAC, more studies are needed from different maternity settings and countries about women's experiences. Women need evidence-based information not only about the risks involved but also positive aspects of VBAC.

Clinical practice guidelines for breast cancer rehabilitation: syntheses of guideline recommendations and qualitative appraisals

BACKGROUND

Despite strides in early detection and management of breast cancer, the primary treatments for this disease continue to result in physical impairments for some of the nearly 3 million people diagnosed annually. Over the past decade, evidence-based clinical practice guidelines (CPGs) have been developed with goals of preventing and ameliorating these impairments. However, translation of these guidelines into clinical practice needs to be accelerated.

METHODS

Relevant health science databases (2001-2011) were searched to identify CPGs on breast cancer rehabilitation for the following impairments: upper extremity restrictions, lymphedema, pain, fatigue, chemotherapy-induced peripheral neuropathy, treatment-related cardiotoxicity, bone health, and weight management.

RESULTS

Recommendations from 19 relevant CPGs were first summarized by impairment within tables; commonalities across guidelines, within each impairment, were then synthesized within the article. The CPGs were rated using the Appraisal of Guidelines for Research and Evaluation II (AGREE II); wide variability was noted in rigor of development, clarity of presentation, and stakeholder involvement. The most rigorous and comprehensive of those rated was the adult cancer pain guideline from the Scottish Intercollegiate Guidelines Network.

CONCLUSIONS

Based on a large body of evidence published in recent years, including randomized trials and systematic reviews, there is an urgent need for updating the guidelines on upper extremity musculoskeletal impairments and lymphedema. Furthermore, additional research is needed to provide an evidence base for developing rehabilitation guidelines on management of other impairments identified in the prospective surveillance model, eg, arthralgia.

Prenatally diagnosed fetal conditions in the age of fetal care: does who counsels matter?

OBJECTIVE

We sought to characterize practices and attitudes of maternal-fetal medicine (MFM) and fetal care pediatric (FCP) specialists regarding fetal abnormalities.

STUDY DESIGN

This was a self-administered survey of 434 MFMs and FCPs (response rate: MFM 60.9%; FCP 54.2%).

RESULTS

For Down syndrome (DS), congenital diaphragmatic hernia (CDH), spina bifida: MFMs were more likely than FCPs to support termination (DS 52% vs 35%, P < .001; CDH 49% vs 36%, P < .001; spina bifida 54% vs 35%, P < .001), and consider offering termination options as highly important (DS 90% vs 70%, P < .001; CDH 88% vs 69%, P < .001; spina bifida 88% vs 70%, P < .001). For DS only, MFMs were less likely than FCPs to think that pediatric specialist consultation should be offered prior to a decision regarding termination (54% vs 75%, P < .001). MFMs reported report higher termination rates among patients only for DS (DS 51% vs 21%, P < .001).

CONCLUSION

MFM and FCP specialists' counseling attitudes differ for fetal abnormalities.

Providers' perspectives on the vaginal birth after cesarean guidelines in Florida, United States: a qualitative study

BACKGROUND

Women's access to vaginal birth after cesarean (VBAC) in the United States has declined steadily since the mid-1990s, with a current rate of 8.2%. In the State of Florida, less than 1% of women with a previous cesarean deliver vaginally. This downturn is thought to be largely related to the American College of Obstetricians and Gynecologists (ACOG) VBAC guidelines, which mandate that a physician and anesthesiologist be "immediately available" during a trial of labor. The aim of this exploratory qualitative study was to explore the barriers associated with the ACOG VBAC guidelines, as well as the strategies that obstetricians and midwives use to minimize their legal risks when offering a trial of labor after cesarean.

METHODS

Semi-structured interviews were conducted with 11 obstetricians, 12 midwives, and a hospital administrator (n = 24). Interviews were recorded and transcribed verbatim, and thematic analysis informed the findings.

RESULTS

Fear of liability was a central reason for obstetricians and midwives to avoid attending VBACs. Providers who continued to offer a trial of labor attempted to minimize their legal risks by being highly selective in choosing potential candidates. Definitions of "immediately available" varied widely among hospitals, and providers in solo or small practices often favored the convenience of a repeat cesarean delivery rather than having to remain in-house during a trial of labor. Midwives were often marginalized due to restrictive hospital policies and by their consulting physicians, even though women with previous cesareans were actively seeking their care.

CONCLUSIONS

The current ACOG VBAC guidelines limit US obstetricians' and midwives' ability to provide care for women with a previous cesarean, particularly in community and rural hospitals. Although ACOG has proposed that women be allowed to accept "higher levels of risk" in order to be able to attempt a trial of labor in some settings, access to VBAC is unlikely to increase in Florida as long as systemic barriers and liability risks remain high.
