Insights

General practitioners in Italy appropriately prescribed antithrombotic therapy for atrial fibrillation (AF) in 34.4% of eligible patients. While comparable to other studies, further improvements in guideline adherence and coordination are needed for optimal stroke prevention.

Area of Science:

  • Cardiology
  • General Practice
  • Pharmacotherapy

Context:

  • Atrial fibrillation (AF) management relies heavily on general practitioners for antithrombotic therapy prescription.
  • Assessing guideline adherence for antithrombotic therapy in non-valvular AF within primary care is crucial for stroke risk reduction.

Purpose:

  • To evaluate the frequency and appropriateness of antithrombotic therapy in general practice for patients with non-valvular AF.
  • To analyze prescription patterns based on thromboembolic risk factors using the CHADS2 score.

Summary:

  • A study of 951 patients with non-valvular AF found 10.1% had contraindications to oral anticoagulants.
  • Among the remaining 850 patients, 34.4% did not receive guideline-recommended antithrombotic therapy, with 12.0% receiving no treatment.
  • Prescription rates were comparable to, or slightly better than, published data but indicate room for improvement.

Impact:

  • Findings highlight the need for enhanced educational interventions for general practitioners regarding AF antithrombotic guidelines.
  • Improved collaboration between cardiologists and general practitioners is essential for optimizing stroke prevention in AF patients.
  • The study provides insights into current antithrombotic prescribing practices in Italian general practices, informing future quality improvement initiatives.

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 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,...

Pulmonary 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...

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
