FISH CAN’T SEE WATER: THE NEED TO HUMANIZE BIRTH

INTRODUCTION
Humanizing birth means understanding that the woman giving
birth is a human being, not a machine and not just a container
for making babies. Showing women---half of all people---that
they are inferior and inadequate by taking away their power to
give birth is a tragedy for all society. On the other hand,
respecting the woman as an important and valuable human being
and making certain that the woman’s experience while giving
birth is fulfilling and empowering is not just a nice extra, it
is absolutely essential as it makes the woman strong and
therefore makes society strong.
Humanized birth means putting the woman giving birth in the
center and in control so that she and not the doctors or anyone
else makes all the decisions about what will happen. Humanized
birth means understanding that the focus of maternity services
is community based primary care, not hospital based tertiary
care with midwives, nurses and doctors all working together in
harmony as equals. Humanized birth means maternity services
which are based on good scientific evidence including evidence
based use of technology and drugs.
But we do not have humanized birth in many places today. Why?
Because fish can’t see the water they swim in. Birth attendants,
be they doctors, midwives or nurses, who have experienced only
hospital based, high interventionist, medicalized birth cannot
see the profound effect their interventions are having on the
birth. These hospital birth attendants have no idea what a birth
looks like without all the interventions, a birth which is not
dehumanized. This widespread inability to know what normal,
humanized birth is has been summarized by the World Health
Organization:
“By medicalizing birth, i.e. separating a woman from her own
environment and surrounding her with strange people using
strange machines to do strange things to her in an effort to
assist her, the woman’s state of mind and body is so altered
that her way of carrying through this intimate act must also be
altered and the state of the baby born must equally be altered.
The result it that it is no longer possible to know what births
would have been like before these manipulations. Most health
care providers no longer know what “non-medicalized birth is.
The entire modern obstetric and neonatological literature is
essentially based on observations of “medicalized” birth. “
World Health Organization (1)
Why is medicalized birth necessarily dehumanizing? In
medicalized birth the doctor is always in control while the key
element in humanized birth is the woman in control of her own
birthing and whatever happens to her. No patient has ever been
in complete control in the hospital---if a patient disagrees
with the hospital management and has failed in attempts to
negotiate the care, her only option is to sign herself out of
the hospital. Giving women choice about certain maternity care
procedures is not giving up control since doctors decides what
choices women will be given and doctors still have the power to
decide whether or not they will acquiesce to a woman’s choice.
Fifteen years ago in Fortaleza, Brazil, a World health
Organization Conference recommended birth be controlled, not
just by individual doctors and hospitals but by evidenced based
care monitored by the government. Birth, which had been taken
from the community and slowly but surly changed into
hospital-based care during the last hundred years, is to be
given back to the community. Now the present conference will
consider the next step---giving birth back to the woman and her
family. Doctors are human; birthing women are human. To err is
human. Women have the right to have any errors committed during
their birthing be their own and not someone else’s.
Labour and birth are functions of the autonomic nervous
system and are therefore out of conscience control. Consequently
there are, in principle, two approaches to assisting at birth:
work with the woman to facilitate her own autonomic
responses---humanized birth; override biology and superimpose
external control using interventions such as drugs and surgical
procedures---medicalized birth.
In practice, care during birth may include a combination of
the two approaches: facilitation of the woman’s own responses
usually dominating out-of-hospital management of birth while the
superimposition of external controls usually dominates hospital
birth management. But whether the care is medicalized or truly
humanized depends on whether or not the woman giving birth is in
absolute control.
WHY MEDICALIZED BIRTH
The past fifteen years has seen a struggle between these two
approaches to maternity care become intense and global. Today
there are three kinds of maternity care: the highly medicalized,
“high tech”, doctor centered, midwife marginalized care found,
for example, in the USA, Ireland, Russia, Czech Republic,
France, Belgium, urban Brazil; the humanized approach with
strong, more autonomous midwives and much lower intervention
rates found, for example, in the Netherlands, New Zealand and
the Scandinavian countries; a mixture of both approaches found,
for example, in Britain, Canada, Germany, Japan, Australia.
Before 200 years ago all birth care was humanized as it kept
the woman in the center and, in general, respected nature and
culture. Today in developing countries there are usually
medicalized maternity services in the big cities while in the
rural areas medicalized services have not yet penetrated and
humanized services remain.
Today prevalent medical opinion is that “modern”, i.e.
Western obstetric-intensive maternity care saves lives and is
part of development and attempts to bring maternity care
excesses under control are retrogressive. The present situation
in developing countries reinforces the idea that the only reason
out-of-hospital, midwife intensive birth still exists in places
is because modern medical practice is not yet available.
But we override biology at our peril. For example, if we stop
using our bodies, they go wrong. It is “modern” to get around in
a car or public transport resulting in little walking much less
running. Then science finds out that our bodies need such
exercise or we get cardiovascular problems. So today the
post-modern idea is to go back to walking and running (jogging)
and this is seen as progressive, not retrogressive. By the same
token, humanizing maternity services is not retrogressive but
post-modern and progressive.
Every change in the human condition, including development,
has the potential for positive and negative effects. The
positive effects of development overwhelm the negative effects
until a level is reached where social and economic benefits
reach everyone, then hidden negative effects begin to emerge.
The data are overwhelming that social and economic development,
most especially maternal education, brings down the infant
mortality rate. But such development also increases the rate of
sudden infant death syndrome (SIDS or “cot death”) by bringing
“modern” ways such as parental smoking and how the infant is
placed for sleeping, factors associated with SIDS. So in highly
developed places such as the Czech Republic SIDS rates are lower
in less developed rural areas than in Czech cities and in Hong
Kong SIDS rates are lower among the less developed families
still following traditional Chinese ways. (2) The negative
effects of development on infant mortality, always there, have
now emerged.
The negative effects of development on maternal mortality are
also emerging. Obstetric interventions such as caesarean section
sometimes save lives and sometimes kills--- maternal mortality
even for elective (non-emergency) caesarean section is 2.84 fold
or nearly three times higher than for vaginal birth. (3) For
fifty years the maternal mortality ratio in the US came down.
Then in the 1980’s the maternal mortality ratio began to rise
and, according to the US Centers for Disease Control and
Prevention, it rose from 7.2 in 1987 to 10.0 in 1990. (4) While
this ratio continued to decline in other industrialized
countries, in the US the maternal death rate continued a slow
but steady rise through the 1990s and according to the World
Health Organization is now higher than at least twenty other
highly industrialized countries. (5)
Because WHO relied heavily in the past on obstetricians from
highly developed countries with little or no experience in
developing countries, their programs tended to emphasize the
role of doctors in birth care. This is a double edged
sword---when Safe Motherhood Programs started in Brazil, it was
gratifying to see maternal mortality fall significantly but
meanwhile caesarean section rates soared, even in the poorest
States. (see below)
Obstetricians often claim the use of “high tech” medicalized
maternity care in rich countries is real progress but the
scientific evidence suggests it is sometimes otherwise. There
has been no significant improvement in highly industrialized
countries the past 20 years in low birth weight rates or
cerebral palsy rates. The slight fall in the perinatal mortality
rate the past 10 years in these countries is due, not to any
fall in fetal mortality, but only to a slight improvement in
neonatal mortality associated with neonatal intensive care and
not with obstetric care. In highly developed countries, all
attempts to show lower perinatal mortality rates with higher
obstetric intervention rates have failed. A US National Center
for Health Statistics study comments: ”The comparisons of
perinatal mortality ratios with cesarean section and with
operative vaginal rates finds no consistent correlation’s across
countries”. (6) A review of the scientific literature on this
issue by the Oxford National Perinatal Epidemiology Unit states:
”A number of studies have failed to detect any relation between
crude perinatal mortality rates and the level of operative
deliveries”. (7)
This suggests that we are now at the point in maternity care
in industrialized countries where the positive effects of
development and technology are approaching the maximum and the
negative effects are surfacing. This helps to explain why
advances in technology and in development cannot lead to
improvements in health unless the technology is in harmony with
natural biological processes and is accompanied by humanized
health care. Here a simple example. If an elective caesarean
section is done after labour has started, it may in some cases
facilitate natural processes. But waiting until labour starts
means doctors lose the possibility of scheduling the procedure
at their convenience. But if, as is almost always the case
today, the doctor tries to circumvent natural processes by
performing elective caesarean section before labour starts,
there is a greater risk of respiratory distress syndrome and
prematurity, both leading killers of newborn infants. We
override nature at our peril.
All of this helps to explain why international development
agencies such as the World Bank are now acknowledging that
economic development cannot lead to improvements in the human
condition unless accompanied by social development, including
education.
The greatest danger with Western, medicalized management of
birth is its widespread export to developing countries.
Scientific evidence shows giving routine IV infusion to every
woman in labour is unnecessary but such a practice in a rich
country, while a waste of money, is not a tragedy. But I have
seen such routine IV infusion during labour in small rural
district hospitals in developing countries where the same
hospitals have so little money they are reusing disposable
syringes. Routine IV infusion during labour in developing
countries is a tragic waste of extremely limited resources. When
developing countries adopt Western obstetric practices which are
not evidence based, the result is other women in those countries
dying of cancer not found early enough because of lack of
attention and funds for such unglamorous but essential care as
outreach cancer screening programs for poor women.
Obstetricians, like all clinicians, work hard to help one
patient at a time. In balancing efficacy and risks, doctors
desire to help puts the focus on efficacy rather than risks. For
example, in US publications there are 41 randomized controlled
trials (RCT) on misoprostol (cytotec) for labour induction
proving efficacy but not a single RCT is large enough to
adequately measure risks. (8) So the Cochrane Library recommends
not using midoprostol for this purpose. (9) But it works and is
easy and cheap so it is used widely in the US, even though not
approved by the FDA for this purpose. Now research is emerging
showing serious risks for using misoprostol for cervical
ripening or labour induction in women with a uterine scar.
(10,11) But it is too late for the many US women with previous
caesarean section whose uterus ruptured after induction with
misoprostol and their many dead babies. So misoprostol for
labour induction on women with previous caesarean section in the
1990s joins prenatal X-ray pelvimetry in the 1930s,
di-ethyl-stillbesterol (DES) for pregnant women in the 1950s and
thalidomide for pregnant women in the 1970s as examples of
obstetric interventions which have had tragic consequences
because they went into widespread use before adequate scientific
evaluation.
Behind these misunderstandings in interpreting scientific
data is the reality that most practicing doctors have little or
no training in science. Furthermore, there is a fundamental
difference between the practice of science and the practice of
medicine. To generate hypotheses, scientists must believe they
don’t know while practicing doctors, to have the confidence to
make life and death decisions, must believe they do know.
Most clinicians also have little or no training in public
health and epidemiology and cannot understand how population
based scientific data applies to individual patients, resulting
in, for example, publishing in prominent clinical journals
objections to using recommended rates for cesarean section. (12)
This failure of some clinicians to understand public health and
epidemiology is too often combined with the failure of public
health professionals to confront clinicians regarding excesses
in clinical practice because of their fear of the power of
clinicians and their loyalty to colleagues in the same
profession. (13)
For guidance in practices, clinicians in most places still
rely on peer review and community standards of practice. Using
fellow doctors as a central element in developing and monitoring
practice guidelines predictably has failed, in large part due to
loyalties to professional colleagues. “Community standards of
practice”, based on leading clinicians practices on individual
patients, still are the gold standard even though they have been
revealed as nothing more than “that’s what we all do” leading to
a lowest common denominator standard of care rather than a best
care standard based on evidence.
The one approach clinicians can understand is single case,
anecdotal evidence. This approach leads to the “what if”
scenario in which applying population data to their practices is
rejected by clinicians because “what if” this or that goes wrong
with an individual patient. There is no better example of this
than planned out-of-hospital birth.
Many clinicians and their organizations continue to believe
in the dangers of planned out-of-hospital birth, either in a
center birth or at home, rejecting the overwhelming evidence
that planned out-of-hospital birth for low risk women is safe.
The clinician’s response to this evidence is “But what if there
is an out-of-hospital birth and something happens?” Since most
clinicians have never attended an out-of-hospital birth, their
“what if” question contains several false assumptions. The first
assumption is that in birth things happen fast. In fact, with
very few exceptions. things happen slowly during labour and
birth and a true emergency when seconds count is extremely rare
and, as we will see below, often in these cases the midwife in
the birth center or home can take care of the emergency.
The second false assumption, that when trouble develops there
is nothing an out-of-hospital midwife can do, can only be made
by someone who has never observed midwives at out-of-hospital
births. A trained midwife can anticipate trouble and usually
prevent it from happening in the first place as she is providing
constant one-on-one care to the birthing woman, unlike in the
hospital where usually nurses or midwives can only look in
occasionally on the several women in labour for which they are
responsible. If trouble does develop, with few exceptions the
out-of-hospital midwife can do everything which can be done in
the hospital including giving oxygen, etc. For example, when a
baby’s head comes out but the shoulders get stuck, there is
nothing which can be done in the hospital except certain
maneuvers of the woman and baby, all of which can be done just
as well by the out-of-hospital midwife. The most recent
successful maneuver for such shoulder dystocia reported in the
medical literature is named after the home birth midwife who
first described it (Gaskin maneuver). (14)
The third false assumption is there can be faster action in
the hospital. The truth is that in most private care the woman’s
doctor is not even in the hospital most of the time during her
labour and must be called in by the nurse when trouble develops.
The doctor “transport time” is as much as the “transport time”
of a woman having a birth center or home birth. Even in hospital
births, when a cesarean section is indicated, it takes on
average 30 minutes for the hospital to set up for surgery,
locate the anesthesiologist, etc. In one study of 117 hospital
births with emergency cesarean section for fetal distress, 52%
of cases had a decision--incision time of over 30 minutes. (15)
So during this 30 minutes either the doctor or the
out-of-hospital birthing woman are in transit to the hospital.
This is why it is important for a good collaborative
relationship between the out-of-hospital midwife and the
hospital so when the midwife calls the hospital to inform them
of the transport, the hospital will waste no time in making
arrangements for the incoming birthing woman. These are the
reasons there are no data whatsoever to support the single case,
anecdotal “ what if” scenario used by some doctors to scare the
public and politicians about out-of-hospital birth.
Recently there is a desirable movement towards basing medical
practice on evidence and many obstetricians work hard to bring
their practices in line with the latest evidence. But still
today many doctors are not familiar with recent evidence nor
with the means to obtain it. In a 1998 British study 76% of
practicing physicians surveyed were aware of the concept of
evidence based practice, but only 40 % believe that evidence is
very applicable to their practice, only 27% were familiar with
methods of critical literature review and, faced with a
difficult clinical problem, the majority would first consult
another doctor rather than the evidence. (16) This helps explain
the continuing gap between clinical practices and the evidence.
Although obstetric care is gradually becoming more evidence
based, there is a tendency not to evaluate obstetric
interventions for their subtle and/or long term risks. For
example, evidence suggests an increasing incidence of certain
neurological problems such as attention deficit disorder,
dyslexia and autism. While attempts are being made to find
causes for these problems, I know of no attempt to determine any
correlation’s with simultaneously increasing obstetric
interventions such as prenatal ultrasound scanning,
pharmacological labour induction, epidural block for normal
labour pain, elective CS.
Another reason for the gap between evidence and practice is
the excuses given by some physicians for why they reject
evidence in their medical practice. These excuses include: the
evidence is out of date; collecting evidence is too slow and
prevents progress; I use clinical judgment and my experience;
using anecdotal “horror stories” to try to prove the need for an
intervention which the evidence has found unnecessary; quoting
evidence which is of poor and/or inadequate quality; “trust me,
I am a doctor”; “stop doctor-bashing”; evidence erodes physician
autonomy. In addition to these excuses, in maternity care common
excuses include: our women have smaller pelvises (no evidence),
our babies are getting bigger (no evidence), our population is
not as homogenous (no evidence).
Some obstetricians, as members of society, tend to blind
faith in technology and the mantra: technology = progress =
modern. The other side of the coin is the lack of faith in
nature, best expressed by a Canadian obstetrician: “Nature is a
bad obstetrician.” So the idea is to conquer nature and results
in the widespread application of attempts to improve on nature
before scientific evaluation. This has led to a series of failed
attempts in the twentieth century to improve on biological and
social evolution. Doctors replaced midwives for low risk births,
then science proved midwives safer. Hospital replaced home for
low risk birth, then science proved home as safe with far less
unnecessary intervention. Hospital staff replaced family as
birth support, then science proved birth safer if family
present. Lithotomy replaced vertical birth positions, then
science proved vertical positions safer. Newborn examinations
away from mothers in the first 20 minutes replaced leaving
babies with mothers, then science proved the necessity for
maternal attachment during this time. Man-made milk replaced
woman-made milk, then science proved breast milk superior. The
central nursery replaced the mother, then science proved
rooming-in superior. If more doctors experienced an earthquake
or volcano, they would realize their ideas of controlling nature
are nothing more than stories to rewrite insignificance.
UNNECESSARY CAESAREAN SECTION: SYMBOL OF DEHUMANIZATION
The quintessential example of medicalization and
dehumanization of birth is unnecessary caesarean section (CS) in
which the surgeon is in charge and the woman no longer has any
control. CS saves lives but there is no evidence that rising CS
rates the past two decades in many countries has improved birth
outcomes. (6,7) How can this be? As indications for CS broaden
and rates go up, lives are saved in a smaller and smaller
proportion of all CS cases. But the risks of this major surgical
procedure do not decrease with increasing rates. It is only
logical that eventually a rate is reached at which CS kills
almost as many babies as it saves.
Women and their babies are currently paying a big price for
the promotion of CS by some doctors. The scientific data on
maternal mortality associated with CS suggest the rising
maternal mortality rates in the US and Brazil may be, at least
in part, the result of their high CS rates. (3 ) Both these
countries need to carefully audit all maternal deaths to test
the strong hypothesis that rising rates of maternal death are
associated with high rates of caesarean section. The data on
other risks for both woman and baby associated with CS mean both
are paying a big price both in the current birth and in future
pregnancies as well. (17 )
So why so much unnecessary CS? When maternity care is
controlled by doctors and midwives are marginalized or absent,
higher CS rates are found. Many studies have shown lower
obstetric intervention rates when midwives attend low risk birth
than when doctors are providing primary birth care to low risk
women. (18 ) It is no coincidence that in the US, Canada and
urban Brazil, where obstetricians attend the majority of normal
births and there are few midwives attending few births, the
highest CS rates in the world are found. Having a highly trained
gynecological surgeon attend a normal birth is analogous to
having a pediatric surgeon baby-sit a normal two-year old child.
It would be a waste of the pediatric surgeon’s time and skills
and, when the young child gets tired and fussy, the surgeon
might be tempted inappropriately to use drugs, where a properly
trained baby-sitter would soothe the baby with a variety of
non-medical techniques---the medicalization of normal childhood
similar to the medicalization of normal birth. High CS rates are
a symbol of the lack of humanization of birth.
The overuse of elective CS and other unnecessary obstetric
interventions also threatens the larger community. Not even the
richest countries in the world have the financial resources to
transplant all the hearts, dialyze all the kidneys, give new
hips to all the people who might benefit from these procedures.
Choices must be made about which medical and surgical treatments
to fund and these choices will determine who shall live. A CS
which is done without any medical indication but only because a
woman chooses it requires a surgeon, possibly a second doctor to
assist, an anesthesiologist, surgical nurses, equipment, an
operating theatre, blood ready for transfusion if necessary, a
longer post-operative hospital stay, etc. This costs a great
deal of money and, equally importantly, a great deal of training
of health personnel, most of which is at government expense,
even if the CS is done by a private physician in a private
hospital. If a woman receives an elective CS simply because she
prefers it, there will be less human and financial resources for
the rest of health care.
This dangerous drain on financial resources, as noted
earlier, is far greater when CS practices in places like the US
are exported to developing countries with far fewer resources
for health services. For example, in one State in Brazil 59
hospitals have CS rates over 80%, three health districts have CS
rates over 70% while an additional 13 health districts have CS
rates over 60% and the entire State has a CS rate of 47.7 %.
(19) Clearly this is a huge drain on Brazil’s limited health
resources. And the women of Brazil also are paying another
price. The data given above proving the higher maternal
mortality with elective CS in the UK is further substantiated by
data showing a recent rise in maternal mortality rates in those
areas of Brazil with these shockingly high CS rates.(20) CS on
demand is an expensive and dangerous luxury.
In the light of these issues, the Committee for the Ethical
Aspects of Human Reproduction and Women’s Health of FIGO ( the
international umbrella organization of national obstetric
organizations) states in a 1999 report: “ Performing cesarean
section for non-medical reasons is ethically not justified.” (21
) And there are individual obstetricians and some medical
organizations working to bring down CS rates and humanize birth.
SOLUTIONS
So far we have not been clever enough, in developed or
developing countries, to take the advantages of medicalized
birth care while avoiding the disadvantages such as the drift to
obstetric excesses. Humanizing birth has the potential to
combine the advantages of Western medicalized birth with the
advantages of redirecting the care so as to honor the
biological, social, cultural and spiritual nature of human
birth. There are several strategies for humanization of
birth---- strategies which will put the woman and the family
back in control of the birth of their own child while empowering
the woman to believe in herself through experiencing what her
own body can accomplish.
The first strategy is education. Those who control
information hold the power. In the past the medical profession
often has maintained control of medical care through protecting
and withholding information. Patient confidentiality, a
legitimate excuse for limiting access to information on
individual patients, is now understood not to be an excuse for
limiting information on grouped data such as hospital data and
community data. The information revolution is profoundly
changing medical care. The advent of the internet and world wide
web is having a profound effect on bringing medical information
to everyone. In the new millenium a global movement is demanding
accountable and transparent health care practitioners and health
care facilities (including hospitals) as a basic requirement of
any democracy. Complete and honest information must be given to
the public, even when it means giving up power and, in some
cases, can be dangerous to the continuation of certain
practices----maternal mortality rates a prime example.
Full information on the good and bad results of medicalized
birth must be given to health care practitioners, public health
officials, politicians and the public. In other words, everyone
must begin to see the water that many doctors and hospitals are
swimming in and see that in many cases it is full of sharks
which may not eat the doctors but may sometimes eat women and
babies.
The need to broaden the horizon of doctors concerning
maternity care is not a new problem. In a medical book published
in the year 1668 is the statement: “Doctors who have never seen
a home birth and yet feel competent to argue against it resemble
those geographers who give us the description of many countries
which they never saw.” We must start by requiring doctors to
look at the water in which modern maternity care exists in order
to get a physiological standard against which they can measure
all their experiences. In an obstetric training program in The
Philippines, every doctor must attend a minimum number of
planned home births. Every obstetric training program should
require visits to planned out-of-hospital births, including
birth centers and home births. Midwives and obstetric nurses in
training need the same experience.
The education of women, especially pregnant women, is of
paramount importance but here the issues is: what are the women
told. In some places prenatal education programs are controlled
by a few obstetricians who insist on giving only doctor-friendly
information to pregnant women. Many anesthesiologists in the US
have managed to gain access to prenatal classes where they
preach the wonders of epidural block and usually say nothing
about the considerable risks of this invasive procedure.
More recently, for some doctors to succeed in promoting women
choosing cesarean sections for which there are no medical
indications it is necessary to provide limited, highly selected
information. (17 ) It is highly unlikely women would ever
consider choosing CS if they were given the full scientific
evidence on the risks for themselves and their babies. The key
ethical issue is not the right to choose or demand a major
surgical procedure for which there is no medical indication but
the right to receive and discuss full, unbiased information
prior to any medical or surgical procedure.
A liberated woman correctly strives not to be controlled by
men, an effort even more difficult if she lives in a male
chauvinist society. There are many ways in which women giving
birth in hospitals in “macho” cultures are oppressed and given
the message that they are not important and not free but
controlled by an often belligerent staff ---for example they are
told not to scream or make loud noise with labour contractions.
But if a woman accepts the medicalized, male dominated
obstetric model of care with its selected information, she gives
up any chance to control her own body and make true choices.
Volumes have been written about how liberating and empowering it
is for a woman to give birth when she controls what happens.
Without fully informed choice, she will give up any control and
comply with the wishes of the doctors and hospitals. Women who
demand choice but get only selected doctor-friendly information
unwittingly buy into the medical position. Sadly a few feminists
who correctly fight for women’s rights have been drawn into
believing biased doctor-friendly information and as a result
have unwittingly promoted the right of women to demand obstetric
procedures which are dangerous to them and their babies.
A second strategy for humanization of birth is the promotion
of evidence based maternity care practices. As mentioned
earlier, using peer review and community standards of practice
has failed to close the gap between present obstetric practices
and the evidence. And in many places public health professionals
and government agencies have failed to aggressively pursue
closing the gap between obstetric practices and evidence, often
out of fear of the power of the medical establishment. (13)
It has been an interesting and educational exercise for me to
come to hospital obstetric units and present to the staff a
simple table with their own rates of interventions ( induction,
episiotomy, lithotomy, operative vaginal, cesarean section) in a
column on the left and the evidence based rates opposite in a
column on the right. The ensuing discussion is often
characterized by more heat than light, always with at least a
few doctors as concerned as I about the gap between their
practices and the evidence. As we enter the era of post- modern
medical care, the GOBSAT (Good Old Boys Sit Around Table)
clinical practice guidelines of yore, royalist in sentiment and
pompous in tone, will be replaced by evidence based practice
guidelines approved by the community.
Another essential strategy in humanizing birth is: who is the
primary care giver for women during pregnancy and birth. The
tradition of doctors insisting on controlling their own
practices with little or no interference from the community or
its representatives goes back a long time. During the course of
the twentieth century, the practice of doctors going on “house
calls” disappeared. As long as doctors provide primary care to
normal, healthy pregnant and birthing women, women will not be
in control and humanization of maternity care will not happen.
Countries must work hard not to allow doctors from places
with highly medicalized maternity care like the US to come and
try to sell the country the visiting doctors own system of
maternity care, a system where nearly every obstetrician and
maternity hospital offers only one style of birth care---a style
not based on scientific evidence but on the absolute control of
the system by the doctors. Maternity care in the US, is a form
of care with extreme medicalization. Doctors give primary care
to over 90 % of normal, healthy women giving birth. As a result,
birth has become a surgical procedure with high rates of
unnecessary interventions. Women giving birth are disempowered
and there are huge wastes of resources, financial and
professional. Twice as much is spent per capita on maternity
care as any other country and midwives are marginalized. This is
not a system to emulate---the US maternal mortality rate,
perinatal mortality rate and infant mortality rate are much
higher than the rates in nearly every other industrialized
country.
By contrast, midwifery has a long tradition of placing the
birthing woman in the center with all the control in the woman’s
hands and with the midwife providing the kind of support which
will empower the woman and strengthen the family. For this
reason, having primary maternity care in the hands of midwives
is a central strategy in humanization of birth.
Countries might want to study the maternity care in countries
much further along the road to humanization such as New Zealand,
The Netherlands, Scandinavian countries. In these countries,
over 80% of women see only midwives during pregnancy and birth
(in or out of hospital) and they have some of the lowest
maternal and perinatal mortality rates in the world.
Considerable scientific research has demonstrated four major
advantages to autonomous midwifery: midwives are safer for low
risk birth, midwives use less unnecessary interventions,
midwives are cheaper, midwives provide more satisfaction.
First, there can no longer be any doubt that midwives are the
safest birth attendant for low risk birth. One meta-analysis of
15 studies comparing midwife-attended birth with physician
attended birth found no difference in outcomes for women or
babies except for fewer low birth weight babies with midwives.
(22 ) Two randomized controlled trials (RCT) in Scotland (23,24)
and 6 RCTs in North America all found no increase in adverse
outcomes with midwife attended birth. (18)
The most definitive study of the safety of midwife attended
birth, published in 1998, looked at all births in one year in
the US---over four million births. Selecting only singleton,
vaginal births and removing cases of social or medical risk
factors, they compared outcomes between midwife-attended births
and physician attended births. Compared with physician attended
births, midwife attended births had 19% lower infant mortality,
33% lower neonatal mortality and 31% lower low birth weight
rates. (25)
After reviewing the extensive evidence for the safety of
midwives, a recent article in an obstetric journal concludes: "A
search of the scientific literature fails to uncover a single
study demonstrating poorer outcomes with midwives than with
physicians for low-risk women----evidence shows primary care by
midwives to be as safe or safer than care by physicians." (18).
The second advantage of midwives over doctors as primary
birth attendants is a drastic reduction in rates of unnecessary
invasive interventions. Scientific evidence shows that, compared
to physician attended birth, midwife attended birth has
statistically significantly: less amniotomy, less IV fluids or
IV medication, less routine electronic fetal monitoring, less
use of narcotics, less use of anesthesia including epidural
block for labour pain, less induction and augmentation, less
episiotomy, less forceps and vacuum extraction, less cesarean
section, more vaginal birth after cesarean section. (18)
The third advantage of using midwives as the principal birth
attendant for most births is cost savings. While it varies from
country to country, midwives salaries are almost always
considerably less than doctor’s salaries. And of course, the
lower intervention rates with midwives mean major cost savings.
The data on cost saving is reviewed in a paper on midwifery in
industrialized countries (18) where, for example, one study
found a cost saving of US $500 for every case where a midwife is
birth attendant.
Another advantage of midwifery care, often disparaged by
advocates of medicalized birth, is the pregnant and birthing
woman’s satisfaction with her care. The midwifery approach
emphasizes the importance of women’s satisfaction. The evidence
in the literature is overwhelming: midwifery care is
statistically significantly more satisfying to the woman and her
family. (18)
Since hospitals are doctor territory and no woman has ever
been in control of her own care in a hospital setting, another
important strategy for humanization of birth is to move birth
out of the hospital. There have always been and always will be
women everywhere who choose planned home birth and need a
midwife to attend the birth. But today, as a result of decades
of propaganda about how dangerous birth is, told by doctors who
are themselves afraid of birth and are told how safe hospital
birth is, told by doctors who themselves need the security of
hospitals, there are many women who have bought into the myth
that home birth is dangerous.
It is unbelievable that obstetric organizations in some
highly industrialized countries such as the US still have the
same official policy against home birth which they wrote in the
1970’s. At that time planned home birth was not separated from
unplanned precipitous out-of-hospital birth which, of course,
had high mortality due to preemies born in taxis, etc. Then when
scientists separated out planned home birth, it proved to have
perinatal mortality rates as low or lower than low risk hospital
birth. A large scientific literature documents this, including
when the home birth practitioner is a nurse midwife (26) or when
it is a direct entry midwife (27-29). A meta-analysis of the
safety of home birth, published in 1997, conclusively
demonstrates the safety of home birth and includes an excellent
review of the literature. (30)
So the real issue with home birth is not safety but the
issues are freedom and sanctity of the family. For the over
eighty percent of women who have had no serious medical
complications during pregnancy, planned home birth is a
perfectly safe choice. Any doctor, hospital or medical
organization attempting to discourage a low risk woman from
choosing home birth is denying basic human rights by withholding
full unbiased information and limiting a woman’s freedom of
choice of place of birth. The birth of a baby is one of the most
important events in the life of the family and when the family
chooses a planned home birth, the sanctity of the family must be
honored.
Because of the frightening propaganda of many in the
obstetrical profession about how dangerous birth is, many women
want the freedom to control their own birthing but need the
‘security’ of an institution. How can women today be in control
of giving birth and be empowered by birth and be assisted by a
midwife and still feel comfortable and protected by an
institution? By choosing an alternative birth center (ABC) which
is ‘free-standing’ (i.e. out-of-hospital) and staffed by
midwives.
The first essential characteristic of an ABC is that it is
free of any control by a hospital. A hospital which claims to
have a ‘birth center’ is like a bakery which claims to sell
‘home-baked bread. To be a birth center, the birthing woman must
be in control of everything that happens to her and her baby.
This means the ABC should be staffed by midwives using protocols
made by midwives.
The type of care provided in an ABC is quite different from a
hospital. In a hospital the doctor is always in absolute control
while in an ABC the woman is in control. In the hospital the
emphasis is on routines while in the ABC the emphasis is on
individuality and informed choice. Hospital protocols are
designed with all the possible complications in mind while ABC
protocols focus on normality, screening and observation. In
hospitals pain is define as an evil to be stamped out with drugs
while in the ABC it is understood that labour pain has a
physiological function and can be relieved with scientifically
proven, non-pharmacological methods such as immersion in water,
changing position and moving about, massage, presence of family,
continuous presence of the same birth attendant.
In the hospital induction is frequent and uses powerful drugs
which increase the pain and has many risks while in the ABC
labour is stimulated with non-pharmacological methods including
walking and sexual stimulation such as massage of the nipples.
In the hospital staff are not always present but come and go and
change every eight hours while in the ABC there is the
continuous presence of one midwife throughout the labour. In the
hospital the new baby is taken away from the mother for various
reasons such as doing a newborn examination while in the ABC the
new baby is never taken from the mother.
Are ABCs a safe place for a woman to give birth if she has
had no complications during the pregnancy? This is a key
question because in the struggle between the medicalized and
humanized approaches to maternity care, the ABC is a big threat
to doctors and hospitals and the industry producing all the
obstetric technologies. Because medicalized birth is so
expensive with costly hospital stay, highly paid obstetricians
using so much costly high tech intervention, the doctors and
hospitals must convince the public and those who control funding
of health services that their way is the only safe way.
Otherwise they will quickly lose much of their business. So
obstetric organizations usually fight against all birth where
they are not in control. Their first line of defense against any
planned out-of-hospital birth is to label it unsafe.
The only way to determine if ABCs are safe is to turn to the
scientific evidence. A thorough review of the scientific
evidence on ABCs (31) reports that in the 1970s and 1980s there
were a number of descriptive studies on ABCs. Then in 1989 a
most important paper on ABCs was published: “The US National
Birth Center Study” involving 84 ABCs and 11,814 births. (32) In
the 1990s seven more studies compared ABC birth with hospital
birth and one RCT was reported. The results of this research
follows.
Regarding safety, the US National Birth Center Study had no
maternal mortality and an intrapartum and neonatal mortality
rate of 1.3 per 1000 live births, a rate comparable to the rates
in low risk hospital births. The infant mortality rate and Apgar
scores in the ABCs was also comparable to low risk hospital
rates. Sixteen percent of ABC births were transferred to the
hospital. Such rates of transfer of planned ABC birth to
hospital because of complications compare favorably with the
number of planned hospital births which are transferred to the
surgical suite because of complications. The intention to treat
analysis was used in which all complications, interventions and
outcomes from ABC births transferred to hospital are included in
the ABC statistics.
The safety of ABC birth is further substantiated by
additional studies done in the 1990s in which the outcomes of
ABC births---perinatal mortality, neonatal mortality, apgar
scores, low birth weight rates---in all studies were as good or
better than the outcomes with hospital birth.
In addition to the evidence for the safety of ABCs, these
studies had further data on the characteristics of women
choosing ABCs. After their ABC birth was over, 99% said they
would recommend ABC birth to their friends and 94% said they
would return themselves to the ABC for any future births. A RCT
found that 63% of ABC women had an increase in self-esteem while
18 % of women with hospital birth had an increase in
self-esteem. (31)
With regard to the promotion of breastfeeding, studies in the
US, Denmark and Sweden all found significantly increased rates
of successful breast-feeding in ABC women.
The review of literature on ABCs (31) compared a number of
obstetrical intervention rates in the US National Birth Center
Study with the rates of obstetrical intervention in all
hospitals in one State (Illinois). In ABCs, 99% were spontaneous
vaginal births compared to 55% of hospital births. Less than 4%
of ABC births had induction or augmentation with artificial
rupture of membranes and/or oxytocin compared with 40% of
hospital births. Routine electronic fetal monitoring was done in
8% of ABC births and 95% of hospital births.
Regional or general anesthesia (including epidural block) was
done in 13% of ABC births and 42% of hospital births. Operative
vaginal birth (forceps or vacuum) was done in less than 1% of
ABC births and 10 % of hospital births. Cesarean section was
done in less than 5% of ABC births and in 21% of hospital
births. Looking at these comparisons of interventions, clearly
the logical question is not if ABC birth is safe but if hospital
birth is safe.
As the news about the safety of ABCs spreads, more and more
are being established. In the past ten years, Germany has gone
from having one ABC to now having over 50 ABCs. In Japan, a
network of midwife birth houses provided a significant part of
maternity services the first half of the last century but during
the American occupation, US Army doctors and nurses put pressure
on the Japanese to close the birth houses. Now, however, there
is a resurgence of birth houses in Japan.
Compared to hospital births, home births and births in ABC’s
are safe, much cheaper, use far less unnecessary interventions,
are more satisfying to the woman and family. In other words,
out-of-hospital birth is an important strategy in humanizing
birth care.
Another strategy in humanizing birth is to integrate
out-of-hospital and in-hospital birth care and practitioners.
This was accomplished with excellent results in Fortaleza Brazil
with community based traditional midwives collaborating closely
with hospital obstetricians. (33) This model program, which had
gained world wide recognition, was sadly eliminated when the
visionary obstetrician who established it died. Data from places
like Australia show that when home birth midwives and local
hospital doctors collaborate, fewer babies die and everyone
learns from each other.
Birth is political. An essential strategy is for advocates of
humanized birth to be politically active. Politicians and
government agencies make crucial decisions about maternity care
and their education about and involvement in humanization of
birth is essential.
Advocates of humanized birth must warn politicians and policy
makers of the use of scare tactics by some of the more
reactionary elements of the medical and nursing establishment
who raise the issue of safety and claim without a shred of
evidence that humanized birth is dangerous---that midwives are
less safe than doctors and out-of-hospital birth less safe than
hospital birth.
Another common scare tactic is for some obstetricians to say
that every out-of-hospital birth transported to the hospital is
a “train wreck”. The answer to this criticism is “of course”. A
competent out-of-hospital midwife will only transport those few
cases where there is a serious problem requiring surgical
interventions not available in the home. So for the
obstetricians who have never attended a home birth (in many
places this is nearly all obstetricians), these out-of-hospital
transports with problems are their only experience with
out-of-hospital birth and they erroneously assume these cases
are representative of all out-of-hospital birth. This is like
the auto mechanic who sees several Mercedes with mechanical
problems and concludes all Mercedes are no good, forgetting that
for every Mercedes he sees in his shop, there are a thousand
Mercedes running fine and therefore not brought to his shop.
This is why doctors need to experience out-of-hospital birth
first hand.
These scare tactics are motivated by the attempt of some
doctors (and sometimes even nurses) to protect maternity care as
their territory. Often doctors attempt to overwhelm legislators
with technical language which implies that only doctors can
possibly understand so the listener must simply “trust me, I’m a
doctor”. Politicians and policy makers should be urged to ask
those making these scare statements “Please show me the
scientific data to prove what you are saying.” It can also be
illuminating for legislators to ask those making scare
statements how many out-of-hospital births they have attended.
CONCLUSION
The final solution is to evolve new social and political forms
for the medical profession and for medical care. And there are
obstetricians joining in the effort to find these new forms for
their profession. Maternity care needs turning around so that,
instead of drifting away from physiology and from the social and
cultural environment, the process moves toward respecting and
working with nature and with the woman and family, turning
control of medical care over to the people. For those who fear
chaos, remember Churchill’s warning: democracy is the worst form
of government until one considers the alternatives.
This turn around has started in places with local public
committees deciding on health care policies and
priorities---post- modern maternity care. Everything about
pregnancy and birth----how it is perceived by society, how the
pain of birth is endured by women, how birth is ‘managed’ by
birth attendants---are highly cultural. Local control leads to
empowerment of women which, in turn, leads to a stronger family
and society---local women need to give birth in local waters.
People have been swimming in the physiological, social and
cultural primordial sea for a long, long time, can see the
water, know where the sharks are and are adept at eventually
finding their way forward to reclaiming humanized birth.
