“…The reason for this is that when designing the study, we primarily aimed at defining endpoints for the treatment of women with preeclampsia in multicenter, randomized, controlled intervention trials. In these, completed antenatal steroid therapy was considered a compulsory inclusion criterion [51,52,53,54,55]. For general clinical practice it would also be of interest how the experts would have decided without having completed antenatal steroid therapy.…”

Preeclampsia is a potentially life-threatening hypertensive pregnancy disorder that carries an acute risk of an unfavorable outcome of the pregnancy but also has consequences for the long-term health of the mother. Women who develop the early form of pre-eclampsia before the 32nd week of pregnancy have the highest risk and are also the most difficult to treat. The severity of pre-eclampsia is not characterized uniformly in Germany, so that the indication for delivery is rather individualized. The aim of this study was to reach a consensus on parameters that could serve as criteria for describing the severity of pre-eclampsia based on the urgency of delivery. To this end, a Delphi procedure was used to present a scenario in which a woman was admitted for preeclampsia before 32 gestational weeks and after completion of antenatal steroid therapy.Clinicians specialized in maternal-fetal medicine from German-speaking countries completed five rounds of a modified Delphi questionnaire. Presented parameters were selected by the section “Hypertensive Pregnancy Diseases and Fetal Growth Restriction” of the German Society of Gynecology and Obstetrics after reviewing the literature. These included objectifiable laboratory or clinical parameters as well as subjective symptoms of the patient. In addition, nine fetal parameters were taken into account. The clinicians were asked to rate presented parameters as an indication for delivery on a Likert scale from 0 to 4 (no indication to absolute indication without delay). For each item, the predefined cut-off for group consensus was ≥ 70% agreement.A total of 126 experts were approached. Sixty-nine experts (54.8%) took part in the first round; of those 50 completed the entire Delphi procedure. A consensus was reached on 14 parameters to be considered rapid preparation for delivery without delay (4 points on the Likert scale). These were among others hepatic hematoma or liver capsule rupture, acute liver failure with fulminant coagulation disorder or disseminated intravascular coagulation, eclampsia, pathologic findings in imaging (e.g. cMRI) or electrocardiogram arranged for new onset of headache or retrosternal pain, respectively. Twenty-six parameters were rated as factors that should be considered in the decision without being absolute (1 to 3 points), and 13 parameters should have no influence on the decision to deliver (0 points). No consensus on severe hypertension as an indication for delivery could be reached for blood pressure values below 220/140 mmHg.A consensus was reached on whether to deliver in preeclampsia typic clinical findings and symptoms. The results can serve as guidance for current clinical practice and for the definition of clinical endpoints in intervention studies. Nevertheless, the isolated criteria are a theoretical construction since the combined deterioration or summation of several factors rather than a single factor most likely influences the decision to deliver and reflect the severity of preeclampsia. Moreover, the degree of hypertension as an indication for delivery remains controversial, unless the patient suffers additionally from complaints. Future research should be enforced to incorporate long-term risks for the mother into a decision aid.
