The proportion of women with a «normal birth» (birth without induction of labour, epidural or spinal analgesia, general anaesthesia, forceps or ventouse delivery, caesarean section, or episiotomy9 10) varied from 58 % for
planned obstetric unit births to 76 % in alongside midwifery units, 83 % in freestanding midwifery units, and 88 % for planned home births; the adjusted odds of having a «normal birth» were significantly higher in all three non-obstetric unit settings (table 5 ⇓).
For the restricted sample of women without any complicating conditions at the start of care in labour, the odds of a primary outcome event were higher for births planned at home compared with
planned obstetric unit births (adjusted odds ratio 1.59, 95 % confidence interval 1.01 to 2.52) but there was no evidence of a difference for either freestanding or alongside midwifery units compared with obstetric units.
The target sample size was at least 57000 women overall: 17000 planned home births, 5000 planned alongside midwifery unit births, 5000 planned freestanding midwifery unit births, and 30000
planned obstetric unit births (of which we estimated 20000 would be low risk).
Babies were significantly more likely to be breast fed at least once for planned births at home and at freestanding midwifery units compared with
planned obstetric unit births.

In the subgroup analysis stratified by parity, there was an increased incidence of the primary outcome for nulliparous women in the
planned home birth group (weighted incidence 9.3 per 1000 births, 95 % confidence interval 6.5 to 13.1) compared with the
obstetric unit group (weighted incidence 5.3, 3.9 to 7.3).
Main outcome measure A 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).
The study was a prospective cohort study with
planned place of birth at the start of care in labour as the exposure (home, freestanding midwifery unit, alongside midwifery unit, or
obstetric unit).12 Women were included in the group in which they
planned to give birth at the start of care in labour regardless of whether they were transferred during labour or immediately after birth.
There was no difference overall between birth settings in the incidence of the primary outcome (composite of perinatal mortality and intrapartum related neonatal morbidities), but there was a significant excess of the primary outcome in births

The adjusted odds of the secondary maternal outcomes — namely, maternal morbidity avoided and «normal birth» — were significantly increased for
planned births in all three non-
obstetric unit settings compared with those
planned in
obstetric units.
For all low risk women, bootstrapped estimates showed that
planned birth in settings other than an
obstetric unit was associated with cost savings and considerable stochastic uncertainty surrounding adverse perinatal outcomes.
In further analyses restricted to women without complicating conditions at the start of care in labour, the adjusted odds of adverse perinatal outcomes were higher for births
planned at home compared with those
planned in
obstetric units (adjusted odds ratio 1.59, 95 % confidence interval 1.01 to 2.52).
The generalised linear model on costs showed that, even after adjustment for clinical and sociodemographic confounders,
planned birth in settings other than
obstetric units remained cost saving compared with the reference category of the
obstetric unit: savings averaged # 134, # 130, and # 310 for
planned births in alongside midwifery units, free standing midwifery units, and at home, respectively (P < 0.001)(see appendix 3 on bmj.com).
Switching from
planned birth in an
obstetric unit to midwifery units was on average cost saving and associated with a non-significant decrease in adverse perinatal outcomes.
Fig 2 Cost effectiveness plane:
planned birth at home compared with
planned birth in
obstetric units for nulliparous low risk women without complicating conditions at start of care in labour
For low risk women without complicating conditions at the start of care in labour, the mean incremental cost effectiveness ratios associated with switches from
planned birth in
obstetric unit to non-
obstetric unit settings fell in the south west quadrant of the cost effectiveness plane (representing, on average, reduced costs and worse outcomes).25 The mean incremental cost effectiveness ratios ranged from # 143382 (alongside midwifery units) to # 497595 (home)(table 4 ⇓).
In this study of the cost effectiveness of alternative
planned places of birth in England in women at low risk of complications before the onset of labour, we found that the cost of intrapartum and after birth care, and associated related complications, was less for births
planned at home, in a free standing midwifery unit, or in an alongside midwifery unit compared with
planned births in an
obstetric unit.
Since the early 1990s, government policy on maternity care in England has moved towards policies designed to give women with straightforward pregnancies a choice of settings for birth.1 2 In this context, freestanding midwifery units, midwifery units located in the same building or on the same site as an
obstetric unit (hereafter referred to as alongside midwifery units), and home birth services have increasingly become relevant to the configuration of maternity services under consideration in England.3 The relative benefits and risks of birth in these alternative settings have been widely debated in recent years.4 5 6 7 8 9 10 Lower rates of
obstetric interventions and other positive maternal outcomes have been consistently found in
planned births at home and in midwifery units, but clear conclusions regarding perinatal outcome have been lacking.
Restriction of the analyses to low risk women without complicating conditions at the start of care in labour narrowed the cost differences between
planned places of birth: total mean costs were # 1511 for an
obstetric unit, # 1426 for an alongside midwifery unit, # 1405 for a free standing midwifery unit, and for # 1027 the home (table 2 ⇓).
Profiles of resource use, and their associated unit costs, for each
planned place of birth are reported in detail in appendices 1 and 2 on bmj.com.25 The total mean costs per low risk woman
planning birth in the various settings at the start of care in labour were # 1631 ($ 1950, $ 2603) for an
obstetric unit, # 1461 ($ 1747, $ 2332) for an alongside midwifery unit, # 1435 ($ 1715, $ 2290) for a free standing midwifery unit, and # 1067 ($ 1274, $ 1701) for the home (table 1 ⇓).
The authors concluded that
planned home births were associated with increased neonatal complications but fewer
obstetric interventions.
The ACOG Committee on
Obstetric Practice's opinion on
planned home birth (2011) noted that although the Committee believes that hospitals and birthing centers are the safest setting for birth, it respects the right of a woman to make a medically informed decision about delivery.
Jane Sandall was and is principal investigator for two studies evaluating models of midwife - led continuity of care (Sandall 2001), and co-investigator on the «Birthplace in England Research Programme», an integrated programme of research designed to compare outcomes of births for women
planned at home, in different types of midwifery units, and in hospital units with
obstetric services.
Some were listed as «suggesting
planned birth at an
obstetric unit» and some as «indicating individual assessment when
planning place of birth».
A
planned home birth might be associated with fewer medical interventions, but in general, home births are associated with an increased risk of
obstetric emergencies when compared with delivery in a medical facility.
Women in the
planned home - birth group were significantly less likely than those who
planned a midwife - attended hospital birth to have
obstetric interventions (e.g., electronic fetal monitoring, relative risk [RR] 0.32, 95 % CI 0.29 — 0.36; assisted vaginal delivery, RR 0.41, 95 % 0.33 — 0.52) or adverse maternal outcomes (e.g., third - or fourth - degree perineal tear, RR 0.41, 95 % CI 0.28 — 0.59; postpartum hemorrhage, RR 0.62, 95 % CI 0.49 — 0.77).
Compared with women who
planned a hospital birth with a midwife or physician in attendance, those who
planned a home birth were significantly less likely to experience any of the
obstetric interventions we assessed, including electronic fetal monitoring, augmentation of labour, assisted vaginal delivery, cesarean delivery and episiotomy (Table 3).
In the subgroup analysis in which we excluded women whose labour was induced by outpatient administration of prostaglandins, amniotomy or both (118 [4.1 %] of women in the home - birth group, 344 [7.2 %] of those who
planned a midwife - attended hospital birth and 778 [14.6 %] of those who
planned a physician - attended hospital birth), the relative risks of
obstetric interventions and adverse maternal and neonatal outcomes did not change significantly.
Our study showed that
planned home birth attended by a registered midwife was associated with very low and comparable rates of perinatal death and reduced rates of
obstetric interventions and adverse maternal outcomes compared with
planned hospital birth attended by a midwife or physician.
Good candidates for
planned TOLAC are those women in whom the balance of risks (as low as possible) and chances of success (as high as possible) are acceptable to the patient and obstetrician or other
obstetric care provider.
Data comparing the rates of VBAC, as well as maternal and neonatal outcomes, after TOLAC to those after
planned repeat cesarean delivery can help guide obstetricians or other
obstetric care providers and patients when deciding how to approach delivery in women with a prior cesarean delivery.
Using this tool we compared the outcomes of
planned home births with those of
planned hospital births for primiparous and multiparous women after controlling for the confounding effects of social, medical, and
obstetric background.
We wished to assess whether the
planned place of birth would lead to differences in perinatal outcome after the confounding effects of
obstetric, medical, and social background were controlled for.
