It is somewhat crazy to think that women who are part of our very educated and proactive group of mothers would ever be compared to mothers in the poorest sections of the country, befuddled by poverty and illiteracy, and then that so called PROOF thrust in our faces as to why we should go to a hospital to give birth.

Talk about appealing to emotions.

My God. Befuddled by poverty and illiteracy. I love it. That's a good one. Nothing in those graphs shows or indicates anything of poverty or illiteracy. In fact that factor alone provides different factors. Nothing I have typed with my fingers in this thread has anything emotional attached to it.

Pick any of the countries that have the lowest infant mortality rate Iceland one of the highest literacy rates and poverty is low, Hong Kong, Canda, Germany, France. See the states that spend more on medicine.

Again, you insert words to push emotion into the discussion (if we can even call it that at this point.)

Is birth INHERENTLY dangerous?

What does that mean? Inherently? Dangerous? Another set of emotionally charged words to obfusicate the discussion at hand.

Make your definition, make your clarification for yourself.

I will say that yes it is inherently dangerous because the evidence shows that death of the infant or the mother is greater than zero. Is jaywalking inherently dangerous? Maybe not in the middle of nowhere, but in midtown Manhattan, it has a risk of greater than zero. Again, the idea here minimizing the danger right? You believe and feel that freebirth defined as unassisted birth at home with no intervention of medically trained staff or midwives, provides you better safety. That is your choice.

Since you asked about Perinatal Mortality Rates, there are MANY studies and lots of data. I will cite just two of them.

Quote:

Perinatal mortality (PNM), also perinatal death, refers to the death of a fetus or neonate and is the basis to calculate the perinatal mortality rate. Variations in the precise definition of the perinatal mortality exist specifically concerning the issue of inclusion or exclusion of early fetal and late neonatal fatalities. Thus the WHO ‘s definition "Deaths occurring during late pregnancy (at 22 completed weeks gestation and over), during childbirth and up to seven completed days of life" is not universally accepted. The perinatal mortality is the sum of the fetal mortality and the neonatal mortality.

Please note that the trend is downward as medicine has gotten better since the 1950's. If your hypothesis and claims were correct, then the perinatal mortality rate would be growing.

Perinatal death associated with planned home birth in Australia: population based study

Key messages

In some countries there is a trend towards high risk home births

This study examined perinatal death rates in Australian home births, including both high and low risk births

The death rate in Australian home births was higher than comparable births nationally and home births in other countries

The higher perinatal death rate in Australian home births was due to the inclusion of predictably high risk births and prolonged asphyxia during labour

While home birth for low risk women can compare favourably with hospital birth, high risk home birth is inadvisable and experimental

Despite decades of political and academic debate the relative merits of home versus hospital birth remain unproved. This is likely to remain so. Comparisons that are sufficiently unbiased and large enough to address crucial safety issues are unlikely to be forthcoming. 1 2 Although home and hospital offer different risks and benefits for births, neither has standard care characteristics. In fact the range from safe to unsafe practice may be wider within each location than it is between them. Addressing what constitutes safe birth practice at home may be a more pivotal concern than attempting to quantify the theoretical differences attributable to place of birth.

In the Netherlands, where 30% of births are planned to be at home, there is a widely accepted list of criteria for home birth.3 When home birth is uncommon, opinions and practice can vary more widely. Thus leaflets on informed choice of place of birth in the United Kingdom do not specify any contraindications to home birth. 4 5 Others have advocated home birth for women at high risk of obstetric complications, 6 7 and trends to abandon risk assessment for home birth are apparent in both Australia8 and the United States.9

We evaluated the outcomes of Australian home births and compared these with all Australian births and planned home births elsewhere.

Data on planned home births
A planned home birth was defined as a birth that, at the onset of labour, was intended to occur at home with the assistance of a home birth practitioner. This definition excluded antepartum transfers, unplanned home births, and births where the woman was supported only by family and friends. Home birth practitioners included midwives and medical practitioners, both registered and non-registered, but not Aboriginal traditional midwives.

Data on home births during 1985-90 were from a database of Homebirth Australia, a national consumers' association that kept a register of practitioners attending home births. Practitioners were asked to complete a detailed notification form for each planned home birth. An annual summary of births attended was requested from practitioners who did not submit these forms.

All home birth practitioners, except one in 1988, supplied minimum data for births during 1985-8. For 1989 and 1990, 207 (89.6%) practitioners provided data (24 non-participants). Information on 576 births attended by non-participants during 1989-90 was obtained from their notifications in home birth support group newsletters.

Overall, information was available for 7002 planned home births during 1985-90. Information came from individual notification forms in 5052 (72%) births, from summaries in 1372 (20%) births, and from home birth support group newsletters in 576 (8%) births. Two additional births resulting in deaths were identified from other sources; these were confirmed by state perinatal data collections.

Data on perinatal deaths
Australian perinatal death refers to stillbirth and death within 28 days after birth, of an infant weighing 500 g or more. This definition includes stillbirths and deaths within the first week and late neonatal deaths.

An audit form was distributed to practitioners who had reported deaths during 1985-7 (20 deaths). All practitioners provided data. A similar request was made for the 11 deaths reported in 1988, but only five practitioners complied. For 1989 and 1990, practitioners reported nine deaths directly to Homebirth Australia; a further eight deaths were reported in newsletters in the states with non-participants. In addition, one home birth group notified a death that was matched in the state's perinatal data collection.

Data to supplement incomplete death reports during 1988-90 were sought from state perinatal data collections and registry data in one state. These sources provided additional data on four of the eight deaths identified only through newsletters during 1989-90, and on 13 deaths with minimum information during 1988-90. One state reported an additional death that met the study's criteria.

Overall, information was available on 50 deaths (five of which were late neonatal deaths) eligible for inclusion in this study. Eleven deaths reported to Homebirth Australia did not meet our criteria and were excluded. Of the 50 deaths, 48 were notified by practitioners to Homebirth Australia or home birth newsletters and two came from other sources.

Data analysis and comparisons
Data on home births were compared with all Australian births during 1985-90 and with planned home births elsewhere, identified from a literature search for comparable data from the 1980s and 1990s. The CIA program was used for statistical analysis.10

Although it is not known how often distance to hospital played a role in decisions on transfer, only once was distance cited as a prohibitive factor. Time in transit, when known, was less than 30 minutes for all deaths.

Of 43 deaths with known birthweight, 11 (25.6%) were less than 2500 g of whom four were malformed. Of 44 deaths of known gestational age, eight (18.2%) were preterm (<37 weeks) and seven (15.9%) post-term (42 weeks).

Twenty six deaths (52%) were associated with intrapartum asphyxia, including three cases of shoulder dystocia and one case of meconium aspiration (table 1). The cause of death in eight cases (16%) could not be explained owing to lack of data.

Asphyxial deaths
Three babies, weighing 4295 g, 4600 g, and 6020 g, died from non-anticipated shoulder dystocia; meconium had been noted during labour for two of them. Most other deaths from intrapartum asphyxia occurred in fetuses known to be at increased risk of perinatal asphyxia (table 2).

Of those babies of known gestational age, seven (33.3%) were outside term: one preterm and six post-term. Five asphyxial deaths were associated with malpresentation: four breech presentations diagnosed before labour and one face presentation. Two intrapartum asphyxial deaths occurred in second twins.

In most cases there had been warning signs during labour. Often these occurred early enough to have allowed timely transfer. In seven cases, meconium or bradycardia, or both, were noted several hours before fetal death. In some cases, risk factors and warning signs accumulated without prompting effective action. In none of the intrapartum asphyxial deaths was the fetus alive on arrival in hospital (table 3).

Two deaths occurred in water births (n=344); in both cases the fetal heart had not been listened to during second stage labour.

Comparison with Australian perinatal mortality
During 1985-90 there were just over 1.5 million births in Australia, giving a death rate (including late neonatal deaths) of 10.8 per 1000 compared with 7.1 per 1000 in planned home births (table 4). In the home birth population, however, severe pathology and very preterm pregnancies with the highest risk of mortality are underrepresented. 11 12 For example in home births with known birthweight, only 1.4% were of low birthweight. 11 12 Birthweight specific mortality was calculated only for the years with the most comprehensive data (1985-8). The death rate for infants weighing 2500 g in 1985-8 was 5.7 per 1000 in home births compared with 3.6 per 1000 nationally (relative risk 1.6; 95% confidence interval 1.1 to 2.4).

Intrapartum deaths mainly accounted for the high death rate in home births of babies weighing 2500 g (table 1). Intrapartum death not associated with congenital malformations or extreme immaturity (defined in the home birth group as an infant weighing <1000 g) was three times as frequent in planned home births than it was nationwide (3.0; 1.9 to 4.8) (table 4).

Comparison with home birth internationally
Comparison of data from reports on home births is hampered by large differences in definition and inclusion criteria. A search of the literature during the 1980s and 1990s identified seven studies with definitions and criteria that permitted comparison with the national Australian data. These studies were from Australasia, 13 14 Europe,15-18 and the United States.19 Australian planned home births had a perinatal death rate about twice as high as these countries (table 5).

Practitioners who continued participation in the study during 1989-90 had a perinatal death rate (3.8 per 1000) similar to that reported internationally, while the death rate for the remainder was estimated at 20.8 per 1000. This cannot be explained by under identification of births in the data for non-participants. Deaths may have been more fully ascertained than births, but home birth newsletters reported births for the non-participants with comparatively large caseloads, and the dataset shows no marked difference in the number of births per year. The number of missing births is therefore probably small.

Our analysis has shown cause for concern about some Australian home birth care. Firstly, the mortality is excessively high when considering that severe pregnancy disorders are grossly underrepresented in this population. 11 12 The only category known to be overrepresented is post-term pregnancy (10.7%). Secondly, in most countries the majority of deaths are preterm antepartum deaths and these are largely excluded by the definition of planned home birth. Thirdly, the intrapartum death rate among normally formed infants weighing 1000 g was three times higher than the national average. Fourthly, over half of all deaths were associated with intrapartum asphyxia. All these babies were born at home or if born in hospital were dead before arrival, while those referred after birth were all diagnosed with severe damage. Yet a large number were known to be at increased risk of intrapartum asphyxia before the onset of labour. Many of the deaths had been preceded by warning signs such as the presence of meconium and fetal bradycardia, in addition to pre-existing risks, without any action being taken or only too little, too late. The risk of death in such circumstances should not be underestimated, particularly as the capacity to care for severely asphyxiated babies at home is limited.

When compared with data on planned home birth in other industrialised countries, the perinatal death rate in Australia was much higher. There are several possible explanations for this. Firstly, our detection and ascertainment of deaths may have been better than it is elsewhere. Low participation in population based studies of planned home births is common. A national study from the United States for example achieved only a 67.6% response rate and surveyed registered midwives only.19

Secondly, Australian home birth practitioners might differ from home birth practitioners elsewhere. Home birth practice in Australia is nearly 100% private practice and characterised by low caseloads. On average during 1985-90, 53% of practitioners attended less than five home births a year, and only 13% attended more than 20 home births a year. 11 12 This contrasts with the Netherlands, for instance, where home midwifery caseloads of more than 100 births a year are common.16 It is not known, however, if practitioners in our study also practised in other settings.

Thirdly, our study also included unregistered midwives. However, comparatively few births were attended by unregistered practitioners alone (n=737) and these births did not have a high death rate (2.7 per 1000).

A fourth, and more compelling explanation, is that some home birth practitioners in Australia no longer offer home birth to women at low risk. At least 18 deaths (36%) in this study occurred in twins, post-term and preterm infants, and breech presentations, which would be contraindications for home birth elsewhere. Post-term births had a death rate twice that of other home births, and home birth mortality was 1 in 14 for breech presentation and 1 in 7 for twins. The two largest contributors to the excessive mortality were an underestimation of the risks of perinatal asphyxia in such births and, more generally, underestimation of the significance of fetal distress. This raises questions about other effects of prolonged asphyxia that were not addressed in this study.

We found only one other study, conducted in the United States, on mortality associated with breech, twin, and post-term births at home.9 This study showed excess mortality in such home births and voiced concern about the trend to encourage midwives to engage in high risk practice. We share that concern. Because of the well established risks and the lack of encouraging outcome data, such practice must be labelled as inadvisable and experimental with all ethical safeguards that pertain to clinical experimentation. Overintervention and lack of choice for women with high risk pregnancies, however, could well encourage some to choose home rather than hospital birth. In many Australian hospitals, women with breech presentation or twins, for example, would only be offered caesarean section.

Our study highlights the need for objective guidance on what constitutes safe practice for birth at home. Given the inadequacy of many national datasets, both in size and quality, such guidance must inevitably draw on international data to be valid and reliable. It may also require ongoing audit to detect patterns of avoidable problems. Australian women, like women elsewhere, will continue to choose to give birth at home. They and their infants are entitled to effective care and support in their choice.

Intrapartum death
Intrapartum death occurs when a baby dies during labor, typically due to a lack of oxygen. Fortunately, intrapartum death is relatively rare today—small consolation, however, for the families who lose much-wanted babies due to accidents during birth.

Studies have identified a number of factors associated with an increased risk of intrapartum death: preeclampsia (toxemia/pregnancy-induced hypertension), intrauterine growth restriction, prolonged pregnancy (more than two weeks beyond the due date), vaginal breech delivery, previous perinatal death, and even physician (or other caregiver) inexperience.

I can see here that ONE of the reasons that can happen is a physician, but it is qualified with the word inexperience. Not, "backed by pharmaceuticals" or "works in dirty cities, malnourished" and whatever qualifiers you've placed to emotionally charge the discussion. All the other causes happen, they are not qualified nor stated as cannot happen in house or hospital.

Early neonatal deaths occur during the perinatal period, and have obstetric origins, similar to those
leading to stillbirths. Worldwide, there are over 6.3 million perinatal deaths a year, almost all of
which occur in developing countries, and 27% of them in the least developed countries alone.
Stillbirths account for over half of all perinatal deaths. One third of stillbirths take place during
delivery, and are largely avoidable. Intrapartum deaths (i.e. those occurring during delivery) are
closely linked to place of, and care at, delivery. In developing countries, just over 40% of deliveries
occur in health facilities and little more than one in two takes place with the assistance of a doctor,
midwife or qualified nurse (2).
Compared with earlier estimates, global and regional neonatal and perinatal mortality rates have
slowly declined. Improvements appear to have been more noticeable in South America than in
other regions of the world.
Thanks to public health interventions, under-five and infant mortality rates are decreasing at a faster
pace than neonatal mortality; consequently, neonatal deaths will represent an increasing proportion
of child deaths. This document will allow countries to review their achievements in the area of
maternal and neonatal health and compare their results with those obtained by other countries.
Problems related to early mortality data will, it is hoped, stimulate further research and collection

managers with comparative information about the nature and extent of the problem in their country.

There is plenty of data showing that deaths during birth have dramatically declined as medicine advances. I have cited a few already.
