III Methodology
Basic principles
The method used to prepare this guideline was determined by the class to which this
guideline was assigned. The AWMF Guidance Manual (version 1.0) has set out the respective
rules and
requirements for different classes of guidelines. Guidelines are differentiated
into lowest (S1), intermediate (S2), and highest (S3) class. The lowest class is defined
as consisting of a
set of recommendations for action compiled by a non-representative group of experts.
In 2004, the S2 class was divided into two subclasses: a systematic evidence-based
subclass (S2e) and a
structural consensus-based subclass (S2k). The highest S3 class combines both
approaches.
This guideline has been classified as: S3
Grading of evidence according to SIGN
To evaluate the level of evidence (levels 1 – 4) of additionally selected primary
studies, this guideline used the classification system of the Scottish Intercollegiate
Guidelines Network
(SIGN) in its most recent version from 2011 ([Table 3]).
Table 3 Grading of evidence according to SIGN (November 2011).

Grading of evidence
The grading of evidence in an S3-guideline using a level-of-evidence system allows
the strength of the recommendations made in the guideline to be graded. The degree
of recommendation is
differentiated into three levels and the different strengths of recommendation
are indicated by the respective choice of words. This commonly used grading of recommendations
is not just used
by the AWMF but also in the National Guidelines on Care (Nationale Versorgungsleitlinien, NVL) issued by the German Medical Association. The wording chosen to indicate the
strength of
the recommendations is explained in the background text.
In this context, the terms “grade”, “level” or “strength” indicate the degree of certainty
about issuing the recommendation after weighing up the benefits and harms but are
not an
indication of whether the recommendation itself is binding. Guidelines are recommendatory
in nature, i.e., they are not binding. Individual statements and recommendations are
differentiated
by symbols and syntax ([Table 4]).
Table 4 Grading of recommendations (based on Lomotan et al., Qual Saf Health Care 2010).

The above-described differentiation of recommendations reflects both the assessment of the evidence and the clinical relevance of the studies
on which the evidence is based as well
as factors which are not included in the grading of evidence such as the choice
of patient cohort, intention-to-treat and outcome analyses, medical actions and ethical
behavior towards the
patient, country-specific applicability, etc. In contrast, strong, moderate or
weak evidence may correspondingly result in a strong, simple or open recommendation.
A recommendation can only
be upgraded or downgraded to a grade A or a grade 0 recommendation if the strength of the evidence
is moderate. In exceptional cases, the highest level of evidence is only accorded
a
limited/open recommendation or vice versa, and this needs to be explained in
the background text.
-
Strong evidence → grade A or grade B recommendation
-
Moderate evidence → grade A or grade B or grade 0 recommendation
-
Weak evidence → grade B or grade 0 recommendation
Statements
Expositions or explanations of specific facts, circumstances or problems without any
direct recommendations for action included in this guideline are referred to as “statements”.
It is
not possible to provide any information about the grading of evidence for these statements.
Achieving consensus and strength of consensus
At structured NIH-type consensus-based conferences (S2k/S3 level), authorized participants
attending the session vote on draft statements and recommendations. The process is
as follows. A
recommendation is presented, its contents are discussed, proposed changes are
put forward, and all proposed changes are voted on. If a consensus (> 75% of votes)
is not achieved, there is
another round of discussions, followed by a repeat vote. Finally, the extent
of consensus is determined, based on the number of participants ([Table 5]).

Expert consensus
As the term already indicates, this refers to consensus decisions taken specifically
with regard to recommendations/statements issued without a prior systematic search
of the literature
(S2k) or where evidence is lacking (S2e/S3). The term “expert consensus” (EC)
used here is synonymous with terms used in other guidelines such as “good clinical
practice” (GCP) or “clinical
consensus point” (CCP). The strength of the recommendation is graded as previously
described in the chapter Grading of recommendations but without the use of symbols; it is only
expressed semantically (“must”/“must not” or “should”/“should not” or “may”/“may
not”).
IV Guideline
1 Information and counselling
This chapter provides recommendations on the information and counselling given to
healthy women during pregnancy to support them to make their individual decisions.
In special situations,
the recommendations given in the appropriate guidelines must be considered (e.g.,
caesarean section, breech presentation [BP], twins, preterm birth, gestational diabetes
[GDM] etc.).

It was calculated that in 2017, 98.7% of all newborn infants in Germany were born
in hospital, and just 1.28% were born in a non-clinical setting [34];
however, no complete statistics are available. In Austria, 1.3% of all births
in the same period took place either at home or in a midwifery-led setting [35]
while in Switzerland around 2.6% of all births took place at home or in a midwifery-led
setting [36].
Recommendation 3.1. has adapted recommendation 1.1.2 of the NICE guideline CG190 (for
a summary of the underlying studies, see below) and has considered steps 1, 4, 6,
7, 8 and 9 of the
International Childbirth Initiative as well as the freedom of choice of every
pregnant woman in Germany as formulated and regulated in Sec. 134a of SGB V and Sec.
24f sentence 2 of the SGB V
to choose the birth setting. Recommendation 3.1. corresponds to the different
birth settings possible (hospital, free-standing midwifery-led unit or home) in Germany,
Austria and
Switzerland.

Recommendation
|

|
In principle, women must be informed about the different options for obstetric settings
which are available to them, e.g., access to one-to-one care from a midwife, access
to
medical care, access to different pain-relieving measures and pharmacological
painkillers, the option to have a vaginal birth for women who have had a caesarean
section, BP or
twins, as well as other aspects.

Recommendation 3.4 is based on NICE recommendation 1.14 and raises the issue of the
experiences women have in different hospital and non-hospital birth settings. “Individual
care” does not
mean that medical and support staff are obliged to comply with every wish expressed
by the woman (or the person(s) accompanying her).

For reasons of consistency, recommendations 3.5 and 3.6 and the following background
information were taken from the chapter Information and Advice of the S3-guideline
“Caesarean Section”,
AWMF registry no. 015 – 084 [58] (cf. Recommendations 3.1.1 and 3.1.3 in that guideline), which in turn largely follow
the recommendations given in the NICE
guideline CG132 Caesarean section [59].
2 General care
Care during the birth includes all stages of the birth described in [Fig. 1]. The data on the duration of the dilation stage is based on the onset of labor,
which in this context is associated with the start of regular, painful and progressive
contractions.
Fig. 1 Overview of definitions of the onset of labor and the different stages of stages
of labor. [rerif]
2.1 Informed decision-making and self-determined birth
The need to enable women and their families to have a self-determined birth while
also complying with legal requirements means that it is imperative for midwives and
doctors to consider
the issue of the extent to which the pregnant woman must be included in decision-making
[60], [61], [62], [63], [64]. In obstetrics, participatory decision-making processes may help to reduce
decision-related conflicts and anxieties during pregnancy [62], can affect the womanʼs satisfaction with the birth process, and may have an impact
on safety
when choosing the type of birth [65].
2.2 Continuous care and support
In this guideline, one-to-one care by a midwife is defined as follows [66], [67]:
-
The provision of obstetric, non-medical supportive care and emotional support and
the provision of information and advocacy to the woman during the active dilation
and expulsion
stages by same midwife while taking existing work-time arrangements into
account. Care provided by the same midwife must be as continuous as possible in accordance
with the womanʼs
needs.
This definition largely corresponds to the definition by Bohren et al. from 2017 [68], [69].

Guideline adaptation: NICE guideline CG190 Intrapartum care for healthy women and

|
|
Level of consensus: 100%
|
|
[69]
|
It is assumed that one-to-one care corresponds to the needs of women for continuous
care and that one-to-one care will also reduce the potential for error which can arise
from suboptimal
management of interpersonal communication. The existing evidence should be classified
as an initial indication for low-intervention births as a result of one-to-one care
[73].
2.2.1 Availability of gynecologists/obstetricians, pediatricians and anesthetists
over a period of 24 hours
It is indisputable that in risky situations women and infants will benefit from the
rapid availability of specialists for gynecology and obstetrics, pediatrics or even
analgesia. But
corresponding studies on this point are lacking, so that even IQWiG evidence
report no. 635 on the attendance and availability of specialized obstetric staff [69] does not permit any statements to be made which would correspond to a level of evidence.
There can be no doubt that in high-risk cases the presence of medical staff is
indispensable. According to the IQWiG evidence report (see guideline report),
the evidence indicating that obstetricians, pediatricians and anesthetists must be
available around the
clock in the context of a vaginal birth at term and for predetermined endpoints
is rudimentary, meaning that no recommendations based on external evidence can be
made.
2.2.2 Experience and expertise of obstetricians (doctors, medical specialists, residents)
and midwives
The evaluation included studies which compared the different levels of experience
and expertise of obstetricians (doctors, medical specialists, residents) and midwives
in hospitals with
one another, based on test and comparator interventions [74], [75], [75], [76], [77], [78], [79], [80], [81], [82].
Although additional training of teams could be expected to have an impact, the identified
evidence is insufficient. Moreover, training programs vary greatly and may be quite
complex,
which makes it more difficult to provide scientific proof of their efficacy.
Because of this, it was not possible to make any recommendations regarding training
programs and possible
minimum case numbers [76] – [82].
2.3 Adaptation of the environment
The different intervention rates according to birth setting [3], [83] suggest that adapting the environment, specifically
the birthing room, could be a possible influencing variable for interventions
[84], [85].
Overall, the body of evidence is insufficient to answer the question whether modifying
the birthing room in a clinical setting increases the rate of low-intervention births
and
contributes to positive maternal and fetal/neonatal outcomes. The general rule
is that all physiological processes during labor are supported better if the environment
imparts a feeling of
security and safety [86], [87].
2.4 Eating and drinking during the birth

|
Recommendation
|
|
GR
B
|
Women may drink during labor. Isotonic drinks should be preferred to water. Women
in labor should be informed that drinking isotonic drinks during the birth can prevent
acidification of the blood and will not result in increased gastric filling.

that a low-fiber diet, e.g., white bread, crispbread or low-fat cheese,
increases gastric filling. It is unclear whether this will create a risk of aspiration
(pieces of food
entering the lungs) if a general anesthetic becomes necessary during the
further course of labor. A light diet consumed during labor has no positive or negative
impact on
maternal or infant outcomes.

3 Monitoring
The Board of the OEGGG does not support all of chapter 5 “Monitoring” for Austria.
For more information on this, please refer to the relevant statements in the guideline
report.
Two aspects are important in this context. Firstly, the dictum “primum nil nocere”
(“first do no harm”) applies: interventions must only be carried out in consultation
with the woman and
only under the condition that the intervention will, in all probability, be more
beneficial than harmful. All possible advantages and disadvantages must be communicated
appropriately to the
patient. The second aspect is adherence to and compliance with all standards
to ensure the best possible safety of the patient. This includes regular training
of the team and
interdisciplinary case discussions, but especially the allocation of sufficient
staff to permit one-to-one care.
3.1 Auscultation of fetal heart sounds
The staffing ratio must ensure that best practice recommendations can be implemented.
For example, it is known that when fetal health is assessed intrapartum, structured
intermittent
auscultation offers greater benefits in low-risk births than CTG monitoring.
For this, the following conditions must be met:
-
one-to-one care must be provided from the start of the active dilation stage (cervical
dilation is approx. 4 – 6 cm or the woman has been admitted to the labor room),
-
the obstetric staff are appropriately qualified, and
-
fetal heart sounds are continuously documented in detail along with any other relevant
obstetric findings.
If these conditions are not met, then CTG monitoring should be carried out.

Possible birth risks must be excluded if intermittent auscultation is used. There
is no evidence showing when and for how long auscultation should be carried out. In
the studies which
were used as the basis for the recommendation in the NICE guideline CG190, auscultation
was carried out as follows:
-
during and immediately after a contraction for at least 1 minute [171]
-
for at least 1 minute after a contraction every 15 minutes during the dilation stage
and every 5 minutes during the expulsion stage [172]
-
during and immediately after at least one contraction for an unspecified period of
time [173].
Relevant intrapartum events must be recorded using a standard system (see recommendation
5.8).

CTG patterns may be categorized as normal, suspicious or pathological ([Table 6]). The general rule is that no decisions must be made during the birth on
the basis of the CTG alone. Influencing factors (maternal and/or fetal) must
be taken into account during the assessment (NICE guideline CG190 [67]).
When CTG patterns are normal, it can be assumed that there is no risk of hypoxia and/or
acidosis and therefore no intervention is required.
If the CTG pattern is suspicious, hypoxia/acidosis are unlikely, and conservative
measures (i.e., correction of reversible causes, close monitoring and further diagnostic
investigations) are indicated. These can include, for example, providing fluids,
checking maternal vital signs and, if necessary, informing another midwife and/or
the attending
obstetrician (see 3.2.11).
If the CTG pattern is pathological, there is a high risk of hypoxia/acidosis, and
conservative and/or invasive measures are indicated. Irreversible causes (e.g., umbilical
cord
prolapse, placental abruption, uterine rupture) must excluded without delay.
Reversible causes must be immediately corrected and/or further diagnostic tests (e.g.,
fetal blood analysis)
must be carried out. If an invasive investigation using fetal blood analysis
cannot be carried out, operative expediting of the birth may be necessary.
All measures must take account of the womanʼs preferences.

Fetal heart rate is not a good surrogate marker for hypoxia and acidosis, as they
are affected by a number of factors but may not be affected by certain types of hypoxia
(NICE guideline
CG190 [67]).
Studies found an association between poor neonatal/infant outcomes and a fetal heart
rate of > 160 bpm. Even though the level of evidence is quite low, a fetal heart rate
of 160 bpm
was set as the upper limit (NICE guideline CG190). Based on empirical observations,
the authors of the NICE guideline consider a fetal heart rate of > 180 bpm to be associated
with a
great risk of fetal hypoxia/acidosis, which is why this rate is considered
to be another upper limit. This has led to there being two categories of fetal tachycardia:
161 – 180 bpm and
> 180 bpm.
Irrespective of the above, studies analyzed for neonatal morbidity and mortality rates
found only a limited association between fetal tachycardia and poor neonatal outcome
(NICE
guideline CG190 [67]).

There is some limited evidence that a fetal heart rate of less than 110 bpm is associated
with adverse fetal/neonatal outcomes. The data is better for a fetal heart rate of
< 100 bpm, although the majority of studies investigated a heart rate of less
than 90 bpm. This was the basis for determining these current threshold values (NICE
guideline CG190
[67]). Empirically, a fetal heart rate of 90 – 99 bpm with a normal baseline variability
and no decelerations may be normal in some pregnancies.
The negative and positive predictive value of fetal bradycardia for a poor neonatal
outcome is only moderately useful (moderate/high specificity, low sensitivity) (NICE
guideline
CG190). Only cases of moderate to severe bradycardia during the birth have
been found to be associated to some extent with a poor neonatal outcome.

Early decelerations without suspicious or pathological CTG patterns must not lead

4 Pain management
Women experience the labor pains very differently. Important variables affecting maternal
satisfaction with the experience of childbirth include labor pains, the feeling of
being in
control, perceived self-efficacy, social support, and the womanʼs own expectations
of the birth [113], [114], [115], [116], [117]. Effective forms of pain relief do not necessarily result in a higher level
of satisfaction with the birth experience [118], [119].

4.2.1 Further research required
The two Cochrane reviews ([140] on TENS and [141] the use of sterile water injections) focused on different methods for
pain relief but defined different endpoints. If the endpoints formulated by
Derry and colleagues in 2012 [141] with regard to pain relief are followed,
then there should be more RCTs on methods of coping with pain which use these
endpoints.
To obtain clear evidence for or against homeopathy, RCTs using a limited number of
homeopathic substances and with comparable designs and endpoints should be carried
out.
It is worth discussing whether the endpoint “pain relief” should be analyzed without
the endpoint “satisfaction with the birth experience”.
4.3 Pharmacological measures
The following chapter references chapter 1.9 (“Pain relief in labour: regional analgesia”)
of NICE guideline CG190. This chapter of the NICE guideline is mainly geared to the
situation in
Great Britain and focuses in detail on substances and means of application which,
for historical reasons, are important in Great Britain. The transferability of those
recommendations to
the German healthcare system is limited, because some of the substances are
not available (e.g., diamorphine = heroin) or in some places they have been replaced
by other substances not
explicitly recommended in the NICE guideline CG190 (e.g., meperidine instead
of pethidine) or historically do not have the same perceived value in German obstetric
practice due to the
widespread availability of neuraxial anesthesia (EA, CSE) compared to Great
Britain (e.g., nitrous oxide).

Quality assurance in obstetrics is considered the nucleus of quality control in the
hospital-based sector in Germany. After the publication of the Munich perinatal study
in 1975 [157], the use of perinatal surveys expanded rapidly in the old German federal states
and the new federal states after reunification. The founding of the
German National Institute for Quality in Healthcare in 2001 together with the
introduction of the DRG billing system in hospitals created a national survey frame
for quality assurance in
obstetrics, and it has been centrally maintained and expanded ever since. Quality
assurance of vaginal births accounts for a large part of the data, and 5 of 8 quality
indicators for
hospital-based statutory quality assurance currently refer to vaginal births
[158].
After some preparations [159], the Society for Quality in Out-of-Hospital Births (QUAG e. V.) was set up in 1999
to cover the outpatient sector. It
records the quality of out-of-hospital births in all of Germany. In the main,
the recorded items resemble those used in the clinical perinatal surveys with the
addition of the special
features of out-of-hospital obstetrics and a consideration of the transition
from the outpatient to the inpatient sector. In principle, the outcomes of births
delivered in hospitals and
births which occurred in out-of-hospital settings could be compared. Since 2015,
QUAG e. V. which was specifically referenced in the German law regulating the remuneration
paid to midwives
(Hebammenhilfevertrag) [160], has been responsible for the external supervision of quality assurance in out-of-hospital
obstetrics. The annual federal
evaluations of the data collected for the out-of-hospital sector are freely
available on the website of QUAG e. V. (www.quag.de).
5.2 Changes in the percentages of modes of birth over time
A cursory inspection of changes in the percentages of hospital births over the past
decade shows that the percentage of caesarean sections increased until the year 2011
but has slightly
decreased again after the introduction of a risk-adjusted indicator for caesarean
sections in 2014. At the same time, the percentage of spontaneous deliveries increased
very slightly from
2014 onwards (from 60.3% to 61.0%). But during the same period the percentage
of vaginal-operative births rose steadily from 6.0% in 2008 to 6.9% in 2017 [158], [161], [162], [163].
5.3 Indicator-based quality assurance
5.3.1 Indicator-based quality assurance for the inpatient sector
Quality is typically measured using quality indicators. In statutory quality assurance
in Germany, the following indicators are currently used to evaluate vaginal births
and as starting
points for quality improvement processes [158]:
-
antenatal corticosteroid therapy for premature births with a prepartum in-hospital
stay of at least two full days
-
the ratio of observed-to-expected (O/E) rate of acidosis for mature singletons with
determination of umbilical artery pH
-
the ratio of observed-to-expected (O/E) rates of acidosis for premature singletons
with determination of umbilical artery pH
-
the presence of a pediatrician during premature births
-
a critical-outcomes quality index for term-born newborns
-
the ratio of observed-to-expected (O/E) rates of grade 3 or 4 perineal tears in spontaneous
singleton births
-
maternal mortality as part of the perinatal survey.
In addition,
i.e., the risk-adjusted rate of caesarean sections, may also be considered as an indicator
of whether there are too few vaginal births.
As part of the implementation of quality indicators relevant for planning purposes
[164], the indicators
-
antenatal corticosteroid therapy in premature infants with a prepartum in-hospital
stay of at least two full days,
-
the presence of a pediatrician during premature births, and
-
a critical-outcomes quality index for term-born infants,
were selected as quality indicators which are important when planning a vaginal birth
and, in accordance with the directive on quality indicators, they were first applied
in practice
using data from 2017.
5.3.2 Indicator-based quality assurance for the out-of-hospital sector
The current indicator for quality assurance in out-of-hospital obstetrics is the ratio
of observed-to-expected rates of transfers during the birth from the planned out-of-hospital
birth
place [160]. Peer reviews and structured dialogs may be initiated to provide support with quality
assurance to service providers working in the
outpatient sector.
5.4 First attempts to create a form of inter-institutional indicator-based quality
assurance
The Scientific Institute of the AOK (WIdO) developed further quality indicators for
in-hospital vaginal births based on standard data for in-hospital births as part of
its quality
assurance project “Quality Assurance with Routine Data (QSR)”. These additional
indicators also take account of follow-up events which occur following the initial
stay in hospital for the
birth [165].
5.5 Quality assurance of structural requirements with a special focus on staffing
requirements
The German Quality Assurance Directive for Premature and Term-born Infants (QFR-RL)
has developed statutory rules for the minimum standards of care which must be provided
to certain
pregnant women and to premature and term-born infants in Germany by hospitals
registered under Sec.108 of the SGB V. The aim is ensure the quality of structures,
processes and outcomes of
care for premature and term-born neonates while also taking the accessibility
of birth facilities across the country into account [166], [167], [168], [169], [170].

10.1
|
Recommendation
|
|
EC
|
Irrespective of the annual birth rate, a sufficient number of midwives must be present
or on call in every obstetric department to ensure the parturient woman will receive
one-to-one care for more than 95% of the time.
|
|
Level of consensus: 100%
|
|
10.2
|
Recommendation
|
|
EC
|
Depending on their previously recorded field of work, senior midwives should be entirely
or partially released from carrying out mundane practical tasks in the obstetrics
department. The extent of their release must be taken into account when
planning staff allocations.
|
|
Level of consensus: 100%
|
|
10.3
|
Recommendation
|
|
EC
|
Midwives who have fulfilled the necessary statutory requirements to work as practical
instructors must be partially released from carrying out mundane practical tasks in
the
obstetrics department in the context of their work as a midwifery instructor.
The extent of their release must be taken into account when allocating staff.
|
|
Level of consensus: 100%
|
|
10.4
|
Recommendation
|
|
EC
|
Student midwives should not be included in the allocation of staff.

6 Appendix
6.1 Statements from the consultation process
6.1.1 Statement of the DGGG, ÖGGG, DEGUM
The professional societies of obstetricians (DGGG, ÖGGG, DEGUM) are of the opinion
that the multidisciplinary care of pregnant women provided by midwives, obstetricians,
pediatricians
and anesthetists in the labor room is superior to the model of midwife-led
out-of-hospital obstetric care, irrespective of classifications of risk, particularly
as the available
professional expertise and technical equipment can be provided within a very
short space of time. It is not possible to predict all complications which may occur
during birth and in the
early puerperium with sufficient certainty, nor can their occurrence be prevented
by cataloguing the risks. A transfer during the birth may considerably delay prompt
intervention in an
emergency. Comparable data such as those available in the UK from the Birthplace
study are lacking for German-speaking countries. The issue of the safety of out-of-hospital
obstetric
care in German-speaking countries must therefore first be examined and evaluated
in studies which involve both midwives and physicians and which are carried out based
on a complete
reporting of all births and their outcomes (including those which may start
in an out-of-hospital setting and end in hospital).
6.1.2 Statement of the ÖGGG
Special vote by the OEGGG regarding the preamble to the AWMF S3 guideline “Vaginal
Birth”
The representatives of the Austrian Society for Gynecology and Obstetrics agree with
the statement by the German professional societies of obstetricians (DGGG, DEGUM,
DGPM) about the
information given to pregnant women if it is published in a prominent position
in the guideline as a preamble:
Preamble:
The professional societies of obstetricians are of the opinion that the interdisciplinary
care of pregnant women provided by midwives, obstetricians, pediatricians and anesthetists
in
hospital-based labor rooms is superior to the model of midwife-led out-of-hospital
obstetric care, as all forms of expertise required to deal safely with any complications
of the birth
are available within a very short space of time.
Despite using a catalog of risks, many complications can still not be predicted with
sufficient certainty.
A transfer, which is expected to occur for around one third of primipara, may delay
prompt intervention in emergencies, endangering the pregnant woman and the unborn
or newborn
child.
Reasons to transfer a woman in labor include, in particular, failure to progress in
labor, the need for effective analgesia for unmanageable labor pains, placental retention
or
placental remnants, a high loss of blood peripartum, complex childbirth injuries,
and neonatal adaptation disorders.
The issue of the safety of out-of-hospital obstetrics in German-speaking countries
should be prospectively investigated in studies involving both midwives and physicians
and should
include the complete recording of all births as well as the recording of perinatal
and peripartum outcomes. As long as the results of an extensive examination of out-of-hospital
obstetric outcomes are not available, the safety of this approach must remain
in doubt.
Comparable data such as those available in the UK from the Birthplace study are lacking
for German-speaking countries. Such data need to be recorded and should include births
which
began in an out-of-hospital setting and were concluded in hospital, irrespective
of the out-of-hospital place of birth.
