Summary
A new Swedish model could prevent half of pregnancy-related venous thromboembolism (VTE) cases. Applying these guidelines for thromboprophylaxis is cost-effective for the healthcare system.
Area of Science:
- Obstetrics and Gynecology
- Hematology
- Public Health
Background:
- Pregnancy-associated venous thromboembolism (VTE) significantly contributes to maternal morbidity and mortality.
- Sweden has introduced a novel risk assessment model for pregnancy-related VTE.
- Evaluating the potential impact and cost-effectiveness of this new model is crucial.
Purpose of the Study:
- To assess the proportion of preventable postpartum VTE cases using the new Swedish risk assessment model.
- To conduct a cost-benefit analysis of implementing the new VTE prevention guidelines.
Main Methods:
- A retrospective case-control study analyzed 37 postpartum VTE cases over 16 years.
- Identified major anamnestic risk factors at delivery.
- Correlated identified risk factors with the new Swedish thromboprophylaxis guidelines.
Main Results:
- 51% of postpartum VTE cases (19/37) and 73% of pulmonary embolism cases (8/11) had ≥2 risk factors, indicating potential eligibility for thromboprophylaxis.
- The cost associated with preventing a VTE case was lower than the cost of treating a VTE event.
Conclusions:
- The new Swedish VTE risk assessment model could potentially prevent approximately 50% of postpartum VTE and 70% of pulmonary embolisms.
- The updated recommendations for thromboprophylaxis appear cost-effective from a healthcare system perspective.

01:29Venous Thrombosis III: Interprofessional Care
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
01:29Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care
Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
01:27Pulmonary Embolism III: Nursing Management
A pulmonary embolism occurs when a thrombus, amniotic fluid, tumor tissue, fat, or air embolus blocks one or more pulmonary arteries. Effective nursing management and patient education are crucial for improving outcomes and preventing recurrence.Nursing management starts with obtaining a comprehensive patient history, particularly noting any history of deep vein thrombosis (DVT). Assess for clinical manifestations, including dyspnea, chest pain, crackles, heart murmurs, and signs of right-sided...
01:30Venous Thrombosis IV: Nursing Management
Nursing management begins with a thorough assessment of the patient's health history. Key factors include trauma to veins, peripherally inserted central catheters, varicose veins, recent pregnancy or childbirth, surgery, bacteremia, prolonged bed rest, atrial fibrillation, COPD, heart failure, cancer, coagulation disorders, myocardial infarction, spinal cord injury, stroke, prolonged travel, recent bone fractures, and dehydration. Review medication intake, particularly oral contraceptives,...
01:19Pulmonary Embolism I: Introduction
A blood clot, or thrombus, is a semi-solid mass composed of fibrin, platelets, and red blood cells. When it forms within a vessel, it can obstruct blood flow, known as thrombosis. If part of the clot detaches, it becomes an embolus that can travel and block distant vessels. When this occurs in the pulmonary arteries, it causes a condition known as pulmonary embolism (PE).Origin and ImpactMost often, the embolus originates from a thrombus in the deep veins of the lower limbs, a condition called...
01:29Pulmonary Embolism I: Introduction
Pulmonary embolism (PE) occurs when a thrombus, fat or air embolus, amniotic fluid, or tumor tissue blocks one or more pulmonary arteries. These blockages originate in the venous system or the right side of the heart.EtiologyPE primarily arises from deep vein thrombosis (DVT) and other hypercoagulable states, such as inherited thrombophilias. Additional etiological factors include venous stasis, commonly seen in obesity, and endothelial injury from surgery and trauma. Less common causes include...
