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 the two approaches.
This guideline was classified as: S2k.
#
Grading of recommendations
The grading of evidence based on the systematic search, selection, evaluation, and synthesis of an evidence base which is then used to grade the recommendations is not envisaged for S2k guidelines. The individual statements and recommendations are only differentiated by syntax, not by symbols ([Table 3]).
Description of binding character |
Expression |
---|---|
Strong recommendation with highly binding character |
must/must not |
Regular recommendation with moderately binding character |
should/should not |
Open recommendation with limited binding character |
may/may not |
#
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 level of evidence for these statements.
#
Achieving consensus and level of consensus
At structured NIH-type consensus-based conferences (S2k/S3 level), authorised participants attending the session vote on draft statements and recommendations. The process is basically 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 4]).

Strong consensus |
> 95% of participants agree |
++ |
Consensus |
> 75 – 95% of participants agree |
+ |
Majority agreement |
> 50 – 75% of participants agree |
– |
No consensus |
< 51% of participants agree |
#
Expert consensus
As the term indicates, this refers to consensus decisions taken relating specifically 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
Introduction
In principle, pregnancies can be terminated using medication or surgery. Which method is best in each individual case should be decided in an open-ended and unbiased discussion with the pregnant woman.
This guideline was compiled in accordance with the regulations of the AWMF (Association of the Scientific Medical Societies in Germany). In accordance with the requirements for S2k-guidelines, the contents of this guideline, based on a systematic search of the literature, were formally agreed upon by a representative interdisciplinary group of experts.
Details on the methodological approach are available in the guidelines report.
This guideline is mainly aimed at physicians who perform abortions and the professionals involved in the care and counselling of women who wish to have an abortion.
It also aims to support women seeking advice, persons working in counselling centres as defined in § 218/219 StGB and patients and their families.
The following recommendations address care structures, provision of information and counselling to support decision-making, the measures required before terminating the pregnancy, and termination of the pregnancy using medication.

|
---|---|
Expert consensus |
Level of consensus +++ |
Women must be informed that abortion is a safe medical procedure and serious complications are rare. |
Consensus-based recommendation 4.E29 |

Antibiotic prophylaxis should not be routinely carried out with medical abortion. |
Consensus-based recommendation 5.E42 |
|
---|---|
Expert consensus |
Level of consensus ++ |
In principle, doxycycline, metronidazole, and β-lactam antibiotics such as cephalosporins are suitable for antibiotic prophylaxis to reduce the risk of infection after a medical abortion; these active agents should therefore be used in cases with a high risk of infection. |
Consensus-based recommendation 5.E43 |
|
---|---|
Expert consensus |
Level of consensus +++ |
A cervical smear should be taken for further examination in women with a relevant risk of or suspected sexually transmissible infection before carrying out the medical abortion. |

Consensus-based recommendation 5.E49 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Pain must be adequately managed. Non-steroidal antiphlogistic agents are suitable for pain management. Oral metamizole may be prescribed. Paracetamol should not be used because of its limited efficacy. |
Consensus-based recommendation 5.E50 |
|
---|---|
Expert consensus |
Level of consensus +++ |
According to the WHO analgesic ladder for adequate pain relief, affected women may be provided with a weak opioid such as tramadol. |
Consensus-based recommendation 5.E51 |
|
---|---|
Expert consensus |
Level of consensus +++ |
An antiemetic such as dimenhydrinate, metoclopramide or ondansetron should be offered because nausea and vomiting are common after taking misoprostol. |

Consensus-based recommendation 5.E55 |
|
---|---|
Expert consensus |
Level of consensus +++ |
If the pregnancy persists, the patient must be informed about the therapeutic options “administering prostaglandins” and “vacuum aspiration” and must be offered a choice of these methods to terminate the pregnancy. |
Consensus-based recommendation 5.E56 |
|
---|---|
Expert consensus |
Level of consensus +++ |
Any suspicion of an ectopic pregnancy must be investigated using additional diagnostic measures. |

Consensus-based recommendation 5.E61 |
|
---|---|
Expert consensus |
Level of consensus ++ |
Serial measurement of serum hCG levels at the time of taking mifepristone and one week later may be carried out to definitively exclude the possibility of a persistent intrauterine or ectopic pregnancy. |
