Retrospective Assessment of the Risk of Peripartum Hemorrhage in Pregnant Women : Retrospective Assessment of the Diagnostic Performance of the HEMSTOP Standardized Questionnaire

N/ACompletedNCT05191251

Brugmann University Hospital3,588 enrolled

Overview

The diagnostic performance of the HEMSTOP (Hematoma, hEmorrhage, Menorrhagia, Surgery, Tooth extraction, Obstetrics, Parents) standardized questionnaire collected during the preoperative anesthesia consultation in order to detect a deficit in hemostasis associated with the risk of hemorrhage in pregnant women will be analyzed. The primary aim of the study is to assess the sensitivity and the specificity of the HEMSTOP questionnaire to identity patients with an abnormal first-line hemostasis test requiring further development by performing second-line hemostasis tests. The second aim of the study is to assess the sensitivity and specificity of the HEMSTOP questionnaire in predicting postpartum hemorrhage.

Inclusion Criteria: Full-term pregnant women who have given birth vaginally or by cesarean section. Patients for whom a HEMSTOP questionnaire could be carried out in prepartum, during the pre-delivery anesthesia consultation. Patients who received follow-up during pregnancy as recommended. Age over 18 Exclusion Criteria: Patients age under the age of 18 Patients who did not have follow-up during pregnancy as recommended Patients taking long-term anticoagulants and/or antiaggregants Patients with a language barrier

Outcomes

Primary Outcomes

Sensitivity and specificity lab tests

Sensitivity and the specificity of the HEMSTOP questionnaire to identity patients with an abnormal first-line hemostasis test requiring further development by performing second-line hemostasis tests will be calculated. Firstline hemostasis tests are aPTT, PT, INR, fibrinogen level and platelet count.

Time frame: 24 hours

Secondary Outcomes

Sensitivity and specificity hemorrhage

Sensitivity and specificity of the HEMSTOP questionnaire in predicting postpartum hemorrhage will be assessed. Postpartum hemorraghe is defined as blood loss greater then 500 mL for vaginal deliveries and greater than 1000 mL for cesarean sections.
