Maternal and perinatal outcomes in women planning vaginal birth after caesarean (VBAC) at home in England: secondary analysis of the Birthplace national prospective cohort study.

ABSTRACT:

Objective

To compare vaginal birth rates in women planning vaginal birth after caesarean (VBAC) at home versus in an obstetric unit (OU) and explore transfer rates in women planning home VBAC.

Design

Prospective cohort study.

Setting

OUs and planned home births in England.

Population

1436 women planning VBAC in the Birthplace cohort, including 209 planning home VBAC.

Methods

We used Poisson regression to calculate relative risks adjusted for maternal characteristics.

Main outcome measures

Main outcomes

(i) vaginal birth and (ii) transfer from planned home birth to OU during labour or immediately after birth.

Secondary outcomes

(i) composite of maternal blood transfusion or admission to higher level care, (ii) stillbirth or Apgar score <7 at 5 minutes, (iii) neonatal unit admission.

Results

Planned VBAC at home was associated with a statistically significant increase in the chances of having a vaginal birth compared with planned VBAC in an OU (adjusted relative risk 1.15, 95% confidence interval 1.06-1.24). The risk of an adverse maternal outcome was around 2-3% in both settings, with a similar risk of an adverse neonatal outcome. Transfer rates were high (37%) and varied markedly by parity (para 1, 56.7% versus para 2+, 24.6%).

Conclusion

Women in the cohort who planned VBAC at home had an increased chance of a vaginal birth compared with those planning VBAC in an OU, but transfer rates were high, particularly for women with only one previous birth, and the risk of an adverse maternal or perinatal outcome was around 2-3%. No change in guidance can be recommended.

Tweetable abstract

Project description:ObjectiveTo compare perinatal outcomes, maternal outcomes, and interventions in labour by planned place of birth at the start of care in labour for women with low risk pregnancies.DesignProspective cohort study.SettingEngland: all NHS trusts providing intrapartum care at home, all freestanding midwifery units, all alongside midwifery units (midwife led units on a hospital site with an obstetric unit), and a stratified random sample of obstetric units.Participants64,538 eligible women with a singleton, term (≥37 weeks gestation), and "booked" pregnancy who gave birth between April 2008 and April 2010. Planned caesarean sections and caesarean sections before the onset of labour and unplanned home births were excluded.Main outcome measureA composite primary outcome of perinatal mortality and intrapartum related neonatal morbidities (stillbirth after start of care in labour, early neonatal death, neonatal encephalopathy, meconium aspiration syndrome, brachial plexus injury, fractured humerus, or fractured clavicle) was used to compare outcomes by planned place of birth at the start of care in labour (at home, freestanding midwifery units, alongside midwifery units, and obstetric units).ResultsThere were 250 primary outcome events and an overall weighted incidence of 4.3 per 1000 births (95% CI 3.3 to 5.5). Overall, there were no significant differences in the adjusted odds of the primary outcome for any of the non-obstetric unit settings compared with obstetric units. For nulliparous women, the odds of the primary outcome were higher for planned home births (adjusted odds ratio 1.75, 95% CI 1.07 to 2.86) but not for either midwifery unit setting. For multiparous women, there were no significant differences in the incidence of the primary outcome by planned place of birth. Interventions during labour were substantially lower in all non-obstetric unit settings. Transfers from non-obstetric unit settings were more frequent for nulliparous women (36% to 45%) than for multiparous women (9% to 13%).ConclusionsThe results support a policy of offering healthy women with low risk pregnancies a choice of birth setting. Women planning birth in a midwifery unit and multiparous women planning birth at home experience fewer interventions than those planning birth in an obstetric unit with no impact on perinatal outcomes. For nulliparous women, planned home births also have fewer interventions but have poorer perinatal outcomes.

Project description:BackgroundVaginal birth after caesarean (VBAC) is a safe mode of birth for most women but internationally VBAC rates remain low. In Australia women planning a VBAC may experience different models of care including continuity of care (CoC). There are a limited number of studies exploring the impact and influence of CoC on women's experiences of planning a VBAC. Continuity of care (CoC) with a midwife has been found to increase spontaneous vaginal birth and decrease some interventions. Women planning a VBAC prefer and benefit from CoC with a known care provider. This study aimed to explore the influence, and impact, of continuity of care on women's experiences when planning a VBAC in Australia.MethodsThe Australian VBAC survey was designed and distributed via social media. Outcomes and experiences of women who had planned a VBAC in the past 5 years were compared by model of care. Standard fragmented maternity care was compared to continuity of care with a midwife or doctor.ResultsIn total, 490 women completed the survey and respondents came from every State and Territory in Australia. Women who had CoC with a midwife were more likely to feel in control of their decision making and feel their health care provider positively supported their decision to have a VBAC. Women who had CoC with a midwife were more likely to have been active in labour, experience water immersion and have an upright birthing position. Women who received fragmented care experienced lower autonomy and lower respect compared to CoC.ConclusionThis study recruited a non-probability based, self-selected, sample of women using social media. Women found having a VBAC less traumatic than their previous caesarean and women planning a VBAC benefited from CoC models, particularly midwifery continuity of care. Women seeking VBAC are often excluded from these models as they are considered to have risk factors. There needs to be a focus on increasing shared belief and confidence in VBAC across professions and an expansion of midwifery led continuity of care models for women seeking a VBAC.

Project description:BACKGROUND:Most women who have a caesarean can safely have a vaginal birth after caesarean (VBAC) for their next birth, but more women have an elective repeat caesarean than a VBAC. METHODS:The aim of this qualitative study was to explore the experiences of women planning a vaginal birth after caesarean (VBAC) in Australia, the interactions with their health care providers and their thoughts, feelings and experiences after an antenatal appointment and following the birth. The study explored the effect of different models of care on women's relationships with their health care provider using a feminist theoretical lens. Eleven women who had previously experienced a caesarean section and were planning a VBAC in their current pregnancy used the 'myVBACapp' to record their thoughts after their antenatal appointments and were followed up with in-depth interviews in the postnatal period. RESULTS:Fifty-three antenatal logs and eleven postnatal interviews were obtained over a period of eight months in 2017. Women accessed a variety of models of care. The four contextual factors found to influence whether a woman felt resolved after having a VBAC or repeat caesarean were: 'having confidence in themselves and in their health care providers', 'having control', 'having a supportive relationship with a health care provider' and 'staying active in labour'. CONCLUSIONS:The findings highlight that when women have high feelings of control and confidence; have a supportive continual relationship with a health care provider; and are able to have an active labour; it can result in feelings of resolution, regardless of mode of birth. Women's sense of control and confidence can be undermined through the impact of paternalistic and patriarchal maternity systems by maintaining women's subordination and lack of control within the system. Women planning a VBAC want confident, skilled, care providers who can support them to feel in control and confident throughout the birthing process. Continuity of care (CoC) provides a supportive relationship which some women in this study found beneficial when planning a VBAC.

Project description:BackgroundThe rates of caesarean section (CS) are increasing globally. CS rates are one of the most frequently used indicators of health care quality. Vaginal Birth After Caesarean (VBAC) could be considered a reasonable and safe option for most women with a previous CS. Despite this fact, in some European countries, many women who had a previous CS will have a routine CS subsequently and VBAC rates are extremely variable across countries. VBAC use is inversely related to caesarean use. The objective of the present study was to analyze VBAC rates with respect to caesarean rates and the variations among areas of residence, hospitals and hospital ownership types in Italy.MethodsThis study was based on information from the Hospital Information System (HIS). We collected data from all deliveries in Italy from January 1, 2010 to December 31, 2014 and we considered only deliveries with a previous caesarean section. Applying multivariate logistic regression analysis, the adjusted proportions of VBAC for each Local Health Units (LHU), each hospital and by hospital ownership types were calculated. Cross-classified logistic multilevel models were performed to analyze within geographic, hospitals and hospital ownership types variations.ResultsWe studied a total of 77,850 deliveries with a previous caesarean section in Italy between January 1, 2010 and December 31, 2014. The proportion of VBAC in Italy slightly increased in the last few years, from 5.8% in 2010 to 7.5% in 2014. Proportions of VBAC ranged from 0.29 to 50.05% in Italian LHUs. The LHUs with lower proportions of VBAC deliveries were characterized by higher values for primary caesarean deliveries. Private hospitals showed the lowest mean of crude VBAC proportions but the highest variation among hospitals, ranging from 0 to 47.1%.ConclusionsHospital rates of caesarean section for women with at least one previous caesarean section vary widely, and only some of the variation can be explained by case-mix and hospital-level factors, suggesting that additional factors influence practices. Identifying disparities in VBAC may have important implications for health services planning and targeted efforts to reduce overall rates of caesarean deliveries.

Project description:OBJECTIVE:Does planned caesarean compared with planned vaginal birth lower the risk of problematic urinary stress, faecal, or flatal incontinence? DESIGN:Women between 320/7 and 386/7 weeks of gestation with a twin pregnancy were randomised to planned caesarean or planned vaginal birth. SETTING:The trial took place at 106 centres in 25 countries. POPULATION:A total of 2305 of the 2804 women enrolled in the study completed questionnaires at 2 years (82.2% follow-up): 1155 in the planned caesarean group and 1150 in the planned vaginal birth group. METHODS:A structured self-administered questionnaire completed at 2 years postpartum. MAIN OUTCOME MEASURES:The primary maternal outcome of the Twin Birth Study was problematic urinary stress, or fecal, or flatal incontinence at 2 years RESULTS: Women in the planned caesarean group had lower problematic urinary stress incontinence rates compared with women in the planned vaginal birth group [93/1147 (8.11%) versus 140/1143 (12.25%); odds ratio, 0.63; 95% confidence interval, 0.47-0.83; P = 0.001]. Among those with problematic urinary stress incontinence, quality of life (measured using the Incontinence Impact Questionnaire, IIQ-7) was not different for planned caesarean versus planned vaginal birth groups [mean (SD): 18.4 (21.0) versus 19.1 (21.5); P = 0.82]. There were no differences in problematic faecal or flatal incontinence, or in other maternal outcomes. CONCLUSIONS:Among women with a twin pregnancy and no prior history of urinary stress incontinence, a management strategy of planned caesarean compared with planned vaginal birth reduces the risk of problematic urinary stress incontinence at 2 years postpartum. Our findings show that the prevalence but not the severity of urinary stress incontinence was associated with mode of birth. FUNDING:Canadian Institutes of Health Research (CIHR) (grant no.

TWEETABLE ABSTRACT:For women with twins, planned caesarean compared with planned vaginal birth is associated with decreased prevalence but not severity of urinary stress incontinence at 2 years.
