1.  INTRODUCTION

  The National Childbirth Trust (NCT) is the leading UK-wide charity offering information and support in pregnancy, childbirth and early parenthood. Every year the NCT is in contact with 600,000 parents and parents-to-be, through our helplines, interactive website, support networks, antenatal classes, and local and national events. We have 48,000 members, 330 branches, and 1,500 trained workers including antenatal teachers, breastfeeding counsellors and postnatal leaders. We campaign for improvements to maternity services and care in the four countries of the UK. The NCT aims for all parents to have an experience of pregnancy, birth and early parenthood which enriches their lives and gives them confidence in being a parent.

  Key areas of evidence for the Sub-Committee.

2.  DATA COLLECTION

Collection of statistics within the maternity services in England is poor, preventing the possibility of complete and reliable audit of health outcomes, preventing comparisons between services, and making it impossible to monitor changing trends. It is not possible therefore to gauge the quality of services or where attention is most needed to reduce inequalities in health and improve public health.

  Data for only 67% of all hospital births were available for 2000-01, a small improvement on 60% of births for 1997-98 (latest NHS Maternity Statistics (2000-01). In the same periods, collection of home birth data increased only slightly from 11% to 12%. Therefore there were no pooled data for 7/8 home births in England. The Department of Health statistician advises that "submission of the [maternity] data tail has continued to pose substantial problems for the NHS".1

  International audit suggests that sub-optimal care makes a significant contributor to perinatal mortality, and that England compares unfavourably with other European countries. 2 It is important that a complete set of statistics is available so monitoring is possible and action can be taken to reduce unsatisfactory care.

  As regards breastfeeding, several of the Department of Health funded projects cannot tell how effective they have been as there is no baseline data on baby feeding. It is essential that a standardised method is agreed as definitions of breastfeeding (exclusive, full, partial, etc) vary widely. With the new Department target for increasing breastfeeding initiation by 2% annually until 2006, it is vital that a comprehensive data collection system is started straight away, with feeding patterns looked at until at least a year from birth.

  There is a demand from both users and health providers for better maternity information. A comprehensive system of data collection has been running in Scotland for many years but no such system exists in England. The administrative task of entering maternity data on to computer need not be a midwifery task; it could be carried out by a data entry clerk.

3.  LACK OF A FRAMEWORK FOR MATERNITY SERVICES PLANNING AND STAFFING

  The Government published the report of the Maternity and Neonatal Workforce Group in January 2003, 3 but it is an interim document and does not set out Government policy on the development of maternity services in terms of policy objectives and the pressing constraints faced by the NHS, most notably midwifery, nursing, obstetric and neonatal staff shortages. The document does, however, say "Current patterns of working and service provision, based on currently forecast level of supply, are not sustainable". Without central guidance about the configuration of primary, secondary and tertiary level maternity and neonatal services and staffing, increasing numbers of units, both small and medium sized, continue to be closed or reconfigured. These changes are taking place without clear evidence of benefit, either in terms of safety or cost, and without consistent objectives incorporated into the planning stages, or sufficient monitoring of the effects.

4.  STAFFING LEVELS WITHIN MATERNITY AND NEONATAL SERVICES AND THE IMPACT ON WOMEN

4.1  Midwifery staffing

  There is a crisis in midwifery staffing, particularly in London and the South East, where some units can be 40% short of the required number of midwives4 and NCT understands that at one London hospital, vacancies for community midwives are running at 70%. One-to-one support in labour by midwifery staff is the Government's "gold standard"5 but according to an audit of midwifery practice, only 78% of women are receiving this level of support. 6 However, a woman's idea of one-to-one support may be different from that of a health professional, and staffing ratios and patterns that enable women and their partners to feel properly supported are vital.

  Midwifery staffing shortages are key when looking at the type of birth experience a woman is likely to have. A woman who is supported continuously throughout her labour and birth is less likely to need drugs for pain relief, or to experience forceps, ventouse or a caesarean section. 7 Good support during labour is particularly important for disadvantaged women and those with special needs who may find it more difficult to access the information they need, to communicate with staff and make their wishes known. 8 Women who are less supported are less likely to labour well and more likely to require medical interventions. Women who are able to achieve a straightforward vaginal birth, maximize their own health and their baby's health. A normal birth makes skin-to-skin contact and breastfeeding easier, and reduces the need for special care and early separation from the mother. It also saves NHS resources. A straightforward birth costs £1,000 less than a caesarean and £350 less than an assisted delivery. 9 Straightforward births, including home births with two midwives attending, use significantly less midwifery time as contact time is focused when and where it is required and the need for clinical care in the postnatal period is significantly reduced. 10

  In addition to simply looking at the numbers of midwives in a unit, the jobs they are doing must be taken into account. For example, a unit may have 25 midwives, but there will be midwives amongst that group who are involved in scanning, or in theatre assisting with caesarean sections, and not actually available to support women who are in labour or on the postnatal ward. When there are midwife shortages in a maternity unit, it is often the postnatal care of women that suffers most. There is evidence that women feel poorly supported in the immediate postnatal period and do not receive sufficient time or consistent information and support when starting to feed their babies. There are fewer midwifery staffing shortages in midwife-led units11 and so looking at how maternity care is delivered could have an important and positive effect on midwifery recruitment and retention.

4.2  The European Working Time Directive (EWTD)

  Implementation of the EWTD by Summer 2004 to cover doctors in training will have an important effect on medical cover in the labour ward. There is broad acknowledgement among politicians, healthcare managers and clinicians that the current number of maternity units and special care baby units cannot be maintained given staffing constraints. Innovative solutions will need to be found to ensure that women can continue to receive high quality, safe care which is responsive to their needs yet delivered as close as possible to their homes within a managed clinical network.

  Implementation of the EWTD can be seen as an opportunity as well as a threat. While women and families may have to travel further to reach their nearest hospital, there are opportunities to develop midwife-led services in units closer to women's homes. Some of those women who need medical care will have further to travel and every effort should be made to make units welcoming to women, their partners and children, easy to access by public transport and private care, and as comfortable as possible. All women should receive individualised care and have access to birth rooms which are comfortable and clean with access to an en-suite lavatory and birth pool, bath or shower. Women using midwife-led units should be told of any additional social support available in non-medical centres. Often those who are socially disadvantaged can benefit from the additional support smaller, more local units offer, including increased support for breastfeeding. NCT would emphasise that the provision of services in maternity units should be based on the needs of women and their families, rather than solely around doctors' training needs

4.3  Staffing levels and the type of birth a woman is likely to have

  The philosophy amongst staff and mangers of a maternity unit is important in determining the type of service women and their families are likely to experience and in many cases, the type of birth a woman will have. Hodnett found, in a descriptive study in Canada12, that the culture of the maternity unit seemed to be important. Units in which midwives and medical staff shared a view that birth was a normal physiological process, took pride in a low caesarean rate and where there were effective multi-disciplinary staff teams were more likely to have a low caesarean rate.

  An observational study by Keith Greene and Mo Harris from Derriford Hospital, Plymouth showed that having a midwife present during labour is not sufficient. Video footage showed midwives sitting with their back to the labouring woman, occupied with the electronic monitor and medical notes rather than providing physical or emotional support13. Most delivery rooms are dominated by a bed which encourages women to lie down and remain still, whereas evidence suggests that labour progresses better if women are able to keep upright and mobile, and contractions feel less painful. In units where straightforward vaginal birth is valued, and health professionals work together to maximise women's chances of achieving a normal birth, intervention rates are low. In Shropshire, women are automatically booked for the midwife-led unit rather than the obstetric unit unless there is a medical or obstetric reason, or she requests it herself14. Caesarean rates are the country's lowest at 10.9%, half the average for England15. Caesarean rates varied widely between units, meaning that there must be variations in clinical practice and standards. The NCT believes that this is not acceptable. In the National Sentinel Caesarean Section Audit, 16 only 3% of first time mothers-to-be said they would choose a caesarean if there was no medical reason.

  In her presentation on the psychological effects of caesarean section at the "Rising Caesarean Rate; causes and effects for public health" conference, Dr Sarah Clement said that eighteen studies had looked at women's birth experiences and all of these found that women who had had a caesarean section perceived their birth experience more negatively than those who had had a vaginal birth. Additionally, two of these studies found that women are more likely to experience puerperal psychosis after a caesarean. 17 The Sentinel Audit found that 21.5% of births in England and Wales were by caesarean section, and of these, 62.9% were "emergency caesareans". This rate has increased over recent years; from 56% of the total in 1980, 57% in 1990 and 60% in 1995 (England only). 18 As there is an increasing trend and emergency caesareans are needed after a normal birth has been attempted and failed, it is important to look at factors which are contributing to that failure.

  Staffing problems lead to stressed and tired midwives, who may be required to look after two or even three woman in labour at once. When close observation and support cannot be provided there is more reliance on electronic fetal monitoring and epidural aneasthesia in order for the system to cope. We welcome the introduction of consultant midwife posts, although there is much scope to expand numbers further as there are currently only 32 consultant midwives employed within the NHS. 19 Consultant midwives can be a positive influence in ensuring high standards of evidence-based care within the maternity unit, and all Trusts would benefit from having one. In addition, it is vital that the central managerial roles, Director of Women's and Children's Services and Head of Midwifery, continue to attract the highest calibre midwives, so that they can bring their knowledge and influence to bear in decisions about strategic planning and financial management. Unless senior midwives are in a position to make strategic decisions and influence how resources are allocated, they are unlikely to be able to develop the services and improve recruitment and retention through improved motivation and morale. High staff turnover and high levels of bank and agency staff break down the collective knowledge and understanding among medical and midwifery staff; there is less experience and less confidence among staff on the delivery suite and in the community. These are some of the factors affecting a woman's opportunity to have a straightforward birth with all its attendant benefits.

4.4  Impact on home births

  In his speech to the Royal College of Midwives conference in May 2001, Alan Milburn said, "Women in all parts of the country, not just some, (should) have greater choice, including the choice of a safe home birth." Currently, only around 2% of babies are born at home, but 20% of women would like to have more information about home birth. 20 Torbay and Brighton both have home birth rates around 10%, so providing the service to many more women than at present is possible within the NHS. Even when women do make a positive choice to have their baby at home, they are often dissuaded by local staff who fear that it would overburden an already stretched service.

  However, Birthrate Plus shows that overall booked home births involve less midwifery time than hospital births21. Women booked for a home birth are more likely to have a straightforward birth without the need for epidural anaesthesia, an instrumental or operative delivery, or nursing care after the birth. When there are midwifery staffing shortages, home birth services are often the first to be withdrawn by Trusts, many of whom see it as an added extra rather than a core service they should be offering to all low-risk women in their area. The Chelsea and Westminster Hospital recently suspended their home birth service completely due to lack of staff. This reaction to staffing difficulties creates a downward spiral, in which healthy women with a normal pregnancy are referred into the acute services rather than referred to community care when they would welcome it. Subsequently more women have major medical interventions involving more medical and midwifery resources.

  Research has shown that low-risk women who booked a home birth were half as likely to have a caesarean section as those who booked a hospital birth. 21 There are long-term health consequences for those who have a caesarean section, including reduced fertility; they are considered high risk in a subsequent pregnancy and will use more healthcare resources as a result. Fully staffed maternity services, including midwives who are experienced and confident in home births are vital if this is to be real option for women all over the country as the Government envisages.

4.5  Paediatric cover and the effect on maternity services

  NCT acknowledges that there will have to be changes in the way specialist neonatal care is provided due to workforce issues. These changes affect the whole service and all parents, those with complex pregnancies and those with straightforward pregnancies who may develop an unanticipated problem. This is why it is so important to develop fully integrated services taking account of issues for the whole of the workforce. In Ashington and Solihull midwives have been trained in resuscitation and examination of the newborn. Emerging findings suggest safe care can be provided for healthy women with a normal pregnancy without having a paediatrician on site, provided there are clear booking criteria and good transfer arrangements in place should they be needed to a fully equipped tertiary unit. For pregnant women and babies with more complex needs availability of specialist paediatric care on-site is essential. It is important in all parts of the service to strike a balance between meeting the social and emotional needs of sick and premature babies and their families and ensuring that medical care can be provided in an effective and efficient manner. Where services are reconfigured, written information should be provided for parents that explains the trade-offs between availability of local services and access to more intensive nursing and medical care and greater expertise.

  Parents who have a child in special care are going through a difficult time, and in any reconfiguration of neonatal services, measures to make that time as easy as possible should be of the highest consideration. Accommodation should be provided for parents who have a baby in NICU to enable them to stay at or near the hospital. Ideally, this should be in self-catering units which can accommodate the whole family. It should be acknowledged that centralisation of services, at both secondary and tertiary care levels, will have considerable costs for families in terms of ease of access, financial costs for travel, subsistence, accommodation, childcare, physical separation and emotional strain.

4.6  Networks of obstetric and midwife-led units working together

  In Wiltshire and Shropshire, there are "hub and spoke" networks of community services around a district general hospital, enabling birth at home or in a small, midwife-led unit to be offered routinely to healthy women with a normal pregnancy. In each of these areas approximately 25% of women give birth in the community rather than in hospital. This gives women the option of a local, low-tech unit, staffed by midwives who specialise in supporting physiological birth and breastfeeding and who know the local community well. They have the back-up of care at the central consultant unit should they want or need it. NCT feels that maternity services organised in this way have a very valuable contribution to play, in terms of giving women choice in where they want to have their babies, in giving greater numbers of women the chance of a positive birth and good postnatal care close to home and midwives a supportive environment in which to work. These units help keep caesarean rates low by giving women a peaceful, unhurried, supportive environment in which to have their baby. They have high breastfeeding rates, helped by full support for the Baby Friendly Initiative (including encouragement of skin-to-skin contact, well informed and committed staff providing time to help with feeds, no formula milk provided by the NHS, etc) and longer postnatal stays with care from supportive midwives. There is evidence that there are fewer staffing shortages where midwives are able to practice "traditional midwifery" and fully use their skills.

5.  TRAINING OF STAFF WORKING WITH PREGNANT WOMEN AND NEW PARENTS

  There are several areas of weakness in the training of health professionals which impact upon the type of birth a woman is likely to have, the support she receives and the health of the new baby.

5.1  Trainee midwives and on-going training of qualified midwives

  During their training, schools of midwifery teach student midwives to provide woman-centred care based on a social model of birth. However, most go on to do their clinical placements and/or work immediately after training in maternity units where a medical model and risk management take priority over the social model of care. In order for new midwives to experience normal birth within the context of their training and when newly qualified, Labour Ward Managers have an important role to play in ensuring that students learn first about straightforward births and that this is reinforced as the norm before they are involved in providing care for women with more complex needs requiring medical care and interventions. This could be ensured by all student midwives receiving a placement at a midwife-led unit or birth centre where straightforward birth is the norm. The use of skilled people to pass on skills that will otherwise be lost to new midwives is vital. During their training, midwives need to learn the importance of patient and public involvement in the development of maternity services. Supervisors of midwives need to be committed to encouraging engagement between staff and users of the service so they have first hand knowledge of how listening to women can improve the services they offer.

5.2  Doctors in training

  Medical students need to learn about normal physiological birth from the practitioners who are experts in normal birth: midwives. Yet research suggests that lines of professional demarcation mean medical students are seen as a low priority for the teaching of clinical skills and knowledge on busy delivery suites. A recent piece by Diane Fraser in the MIDIRS Journal highlighted that medical students were easily "forgotten about" and were a lesser priority for the trainees' co-ordinator. 22 As junior doctors' placements on the labour ward are shorter than trainee midwives, ensuing that this time is positively spend in a caring and supportive atmosphere that values students is important. It is widely acknowledged that younger obstetricians tend to be more defensive in their practice than older ones, intervening more frequently and rapidly to monitor, augment or deliver with instruments or surgery. If this is to be avoided in future, it should be a priority of midwives to educate junior doctors well during training.

5.3  Training in breastfeeding support

  It is widely recognised that the training of health professionals23 has not provided staff with skills and information to support breastfeeding. There have been some improvements recently, but there is a long way to go to ensure that all staff are consistently positive about women's ability to breastfeed and know how to support that decision. Midwives, healthcare assistants, health visitors and other staff who have contact with new mothers need sound knowledge about the physiology of breastfeeding, the health benefits of breast milk, and the need for a woman-centred, hands-off approach to providing support. In addition, staff need to have worked through their own attitudes, so as to identify any mental blocks they may have preventing them from providing unambiguous support.

5.4  Labour and birth in water

  Increasing numbers of maternity units are installing water pools for women to use during labour and birth. However, anecdotal evidence from midwives and women show that in many cases, because staff lack the confidence and training to support women using them, they are little used. 24 In a UK study comparing low risk "land" and `water' births, babies born in water were less likely to die or need admitting to Special Care than comparable babies born on dry land. 25 Beneficial effects include maternal relaxation, less painful contractions, shorter labours, less need for augmentation, less need for pharmacological analgesics, more intact perinea, and fewer episiotomies and using water may reduce the need for pharmacological pain relief. 26, 27

6.  HEALTH OF THE BABY

  Factors that are important for the health of the baby, and which are affected by staffing levels and training are:

6.1  Antenatal classes

  Only about 50% of first time mothers attend some antenatal classes. There is evidence that by attending

antenatal classes, first time mothers experience better labours and are less likely to suffer mental health problems in the early days as a new parent. 28 In areas where midwifery staffing levels are low, or the Trust is looking to save money, antenatal classes are often a service that is seen as dispensable. NCT understand that currently, two large Trusts in London and the West Midlands have cancelled parentcraft classes due to staff shortages. In addition, to preparing women for labour, what to expect in hospital, caring for a new baby, antenatal classes enable women to exchange experiences and ideas with each other, providing invaluable mutual support. Women who meet other mothers they know around the time of the birth and in the weeks afterwards have a ready-made support network to help them cope with the stresses of new motherhood. We therefore believe that cutting antenatal classes is short-sighted. NHS antenatal classes, conducted by midwives who are trained and confident in teaching, and offered in different languages in areas where there are significant non-English speaking populations, should be available to all first time parents.

6.2  Breastfeeding

  Breastfeeding rates in the England are amongst the lowest in Europe, with only 28% of babies receiving any breastmilk at four months of age. 29 Yet breastfeeding is one of the simplest and most effective ways of improving the health of our children. Currently the decision to breastfeed is related to age, social class and mother's education so that children who are most at risk of poor health (due to poor housing, overcrowding, parental smoking and other social factors) are least likely to be breastfed. Formula fed babies are five times more likely to be admitted to hospital with gastro-enteritis in their first year30, twice as likely to develop atopic eczema, wheezing31 and ear infections32 and five times more likely to have a urinary tract infection33 than babies who are breastfed for at least four months. 34 For premature babies, there is no doubt that human milk reduces the risk of the life-threatening bowel disease, necrotising enterocolitis, and therefore saves lives as well as reducing hospital costs. 35

  One study, based on data from Scotland and the US, looked at the cost of lower respiratory tract illnesses, otitis media, and gastrointestinal illness in babies. 36 In the first year of life, after adjusting for confounders such as maternal education and maternal smoking, there were 2,033 more visits to the doctor, 212 more days of hospitalisation, and 609 excess prescriptions for these three illnesses per 1,000 never-breastfed babies compared with 1,000 babies exclusively breastfed for at least three months. Research also suggests that, on average, children who are formula-fed as babies have higher blood pressure37, lower scores on intelligence tests38, a greater risk of developing obesity39 and childhood diabetes40 all of which have economic consequences.

  There are also long-term health benefits for women. The risks of breast cancer41, some forms of ovarian cancer and osteoporosis leading to hip fracture are higher in women who have not breastfed. 42

  It is clear that breastfeeding provides immediate and long-term benefits to the health and growth of babies. But there is more to breastfeeding than the simple provision of nutrients and other factors that protect against infections, allergies and atopic diseases. It is the unique and intimate way of nurturing babies that may also effect the cognitive, behavioural and emotional development of the young child. Most mothers want to breastfeed, yet nine out of 10 who stop in the first six weeks would have liked to continue for longer. 29 We are not supporting women to nurture their children in the way they wish.

  Breastfeeding is a skill to be learnt by both the woman and her baby and many women find the initial hours and days of breastfeeding challenging. However, being surrounded by supportive staff to encourage and assist the new mother is vital. In smaller midwife-led units, or units that have adequate midwifery staffing levels, women are more likely to get good support from midwives. This is demonstrated by the many small units that have achieved UNICEF Baby Friendly Status, showing that they are committed to helping women establish and support successful breastfeeding. In Scotland, an audit of breastfeeding rates at hospitals that had achieved Baby Friendly Status, showed that there was a 10% average increase in rates. 43 NCT would like to see all hospitals and community practices achieving Baby Friendly Standards as we believe it would benefit the health of mothers and babies. Where staffing levels are inadequate and midwives are very busy, there is evidence that support for breastfeeding is neglected. 44 However, good support in the first few days reduces the incidence of problems such as sore nipples45 and women believing that they have insufficient milk46, enabling more women to breastfeed for longer. "Selective visiting" has become the norm for postnatal care by midwives at home, which lasts for 10 days or longer. Although focussing resources on those women who most need additional support makes sense in terms of reducing health inequalities, there is evidence that with less routine care, more women run into breastfeeding difficulties that could be overcome with early encouragement can support.

  As public health can be improved significantly through increased breastfeeding, there is a need to review patterns of visiting and how community midwives' time is spent to see if more effective support could be provided. Many women report that support available to them suddenly vanishes at the end of their care from a midwife, usually at ten days after the birth. A better way of making the transition to health visitor care is needed, possibly at a later time47 with more integration, more overt support for breastfeeding from health visitors (many of whom may need further training in this regard) and more emotional support for women themselves.

6.3  Mental health

  In every 1,000 births, 100-150 women will suffer a depressive illness and one or two women will develop a puerperal psychosis. 48 If women suffer mental health problems during pregnancy and in the postnatal period, there is growing evidence about the effect that will have on the relationship between the mother and baby, and on the baby's future mental health and well-being. Boys are at particular risk of developing behavioural problems. 49 Therefore training in looking for symptoms and having the time to talk to women is important. Problems with lack of staff and staff time, by midwives, GPs and health visitors can have a detrimental effect on the types of services they are able to offer women and as a consequence, on the health of the baby. Women who are identified at greater risk of developing mental health problems may benefit from additional postnatal visits, interpersonal therapy and/or antenatal preparation. 50
