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

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.
