Insights

Real-world data show that venous thromboembolism (VTE) is often treated with combined oral and parenteral anticoagulants, with direct oral anticoagulants (DOACs) like apixaban being most common. Extended anticoagulation was frequent and adherence rates were high.

Area of Science:

  • Cardiology
  • Hematology
  • Clinical Pharmacy

Background:

  • Real-world data are crucial for guiding clinical practice in venous thromboembolism (VTE) management.
  • Understanding current anticoagulation strategies for VTE is essential.

Purpose of the Study:

  • To determine the types and duration of antithrombotic treatments used in patients with VTE.
  • To investigate anticoagulation dosage, persistence, and adherence in VTE patients.

Main Methods:

  • A prospective, multicenter observational study involving 600 Greek adults with VTE.
  • Data collection included baseline, 3-month, and 6-month follow-up assessments.
  • Analysis focused on treatment patterns, risk factors, and adherence.

Main Results:

  • The most common VTE presentations were pulmonary embolism (PE) and deep vein thrombosis (DVT).
  • Direct oral anticoagulants (DOACs), particularly apixaban, were the predominant oral anticoagulants used, often in combination with parenteral agents.
  • Forty-one percent of patients received extended anticoagulation (>6 months), primarily at standard doses, with high adherence and persistence rates observed.

Conclusions:

  • Current VTE treatment frequently involves a combination of oral and parenteral anticoagulants, with DOACs like apixaban being a leading choice.
  • Extended anticoagulation is common in VTE management, with persistent risk factors influencing its use.
  • High rates of adherence and persistence were noted for both DOAC and non-DOAC anticoagulant therapies.

Venous 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...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...

Venous Thrombosis I: Introduction

Venous thrombosis, the most common disorder of the veins, involves the formation of a thrombus or blood clot associated with vein inflammation. It can be classified as either superficial vein thrombosis or deep vein thrombosis.Superficial Vein Thrombosis: This involves the formation of a thrombus in a superficial vein, usually the greater or lesser saphenous vein. Though less severe than deep vein thrombosis (DVT), SVT can lead to complications if untreated.Deep Vein Thrombosis (DVT): This...

Varicose Veins II: Diagnostic Studies and Interprofessional Care

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

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.
