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

Study Overview
=================
Brief Summary
-----------------
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.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | 24 hours | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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. | 24 hours |
