Venous thromboembolism (VTE) is one of the severe complications of total hip arthroplasty (THA) and total knee arthroplasty (TKA). The incidence of VTE could be reduced if preventive antithrombotic medicines are used; however, the incidence of bleeding may increase. Rivaroxaban is a factor Xa inhibitor that prevents VTE after THA or TKA. This study is designed to confirm the efficacy and safety of rivaroxaban in Taiwan. This is a retrospective database study based on the data of 6996 patients provided by the Taiwan National Health Insurance Research Database from 2008 to 2012. The data included the number of prescription, the cost of prescription, and case number for patients treated with antithrombotic agents for the prevention or treatment of joint arthroplasty complications (including THA, TKA, partial hip arthroplasty, revision THA and TKA), and the incidence of thrombosis and hemorrhage from year 2008 to 2012. The overall postoperative VTE rate was 0.49%. Compared with other antithrombotic drugs, rivaroxaban and heparin analogs can reduce the percentage of thrombosis. We also found that the expenditure and hospitalization was less in the rivaroxaban group than in the heparin analogs group. Because some benefits of rivaroxaban were found in our study, further cost-effective and drug safety studies are warranted. It is important to consider the cost-effective principle for the use of antithrombotic drugs in preventing thromboembolic complications after total joint arthroplasty.

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...

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...

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.

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...

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...
