Brief Summary

The main objective is to reduce the incidence of venous thromboembolism (VTE) in orthopedic postoperative patients based on the potential benefit of using rivaroxaban as a monotherapy. It is around efficacy and safety evaluation of using rivaroxaban as a monotherapy prophylactic agent in patients undergoing orthopedic surgeries taking into the account the reliable selection of patients most benefit. Answering questions about additional cost benefit from the perceptive of the cost-effective analysis on extrapolating the results emerged to our university teaching hospital setting are going to be evaluating as well.

Outcome Measures

Primary Outcomes (3)

  • Any deep-vein thrombosis (DVT)

    Validated clinical prediction rule like Wells Clinical Model is recommended to estimate pretest probability of deep venous thrombosis. Duplex ultrasonography is the preferred test to diagnose deep-vein thrombosis (DVT). Symptoms and signs of DVT may include unilateral leg swelling, pain in the affected leg, calf tenderness in affected leg, increased leg warmth, erythema of affected leg, or a "palpable cord" may be felt in the affected leg. DVT is going to be assessed using Clinical assessment, D-dimer test, Duplex ultrasonography and Venography according to Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines and based on availability and clinical circumstances.

    up to 35 days

  • Nonfatal pulmonary embolism (PE)

    Regarding Pulmonary Embolism (PE), diagnosis is suspected in patients with dyspnea, tachypnea, pleuritic chest pain, cough, and/or fever. Diagnosis begins with initial risk stratification "Wells Clinical Model for Evaluating the Pretest Probability of pulmonary embolism (PE) " based on presence of shock or persistent hypotension to identify patients at high risk of early mortality. PE is going to be assessed using Clinical assessment, D-dimer test, Computerized tomography, Ventilation/perfusion (V/Q) scanning and Pulmonary angiography according to American College of Chest Physicians Evidence-Based Clinical Practice Guidelines and based on availability and clinical circumstances.

    up to 35 days

  • Death

    Death from any cause including venous thromboembolism

    up to 35 days

Other Outcomes (2)

  • Major bleeding risk

    After 4 hours of the first dose and up to 2 days after the last dose of the study drug.

  • Other on-treatment bleeding

    After 4 hours of the first dose and up to 2 days after the last dose of the study drug.

Study Arms (2)

Rivaroxaban arm

EXPERIMENTAL

Rivaroxaban 10 Milligrams

Drug: Rivaroxaban 10 Milligrams

Enoxaparin Arm

ACTIVE COMPARATOR

'Enoxaparin 40 Milligrams /0.4 Milliliters Prefilled Syringe

Drug: Enoxaparin 40 Milligrams/0.4 Milliliters Prefilled Syringe

Interventions

The first group is to be on Rivaroxaban 10 mg with dosage according to the orthopedic approved regimen (10 mg once daily 6-10 hours after the surgery; recommended total duration of therapy: 12 to 14 days; The American College of Chest Physicians (ACCP) recommendation: Minimum of 10 to 14 days; extended duration of up to 35 days suggested.

Rivaroxaban arm

The other group will be administered the standard of care (SOC) enoxaparin as follows: Once-daily dosing: 40 mg once daily, with initial dose within 9 to 15 hours before surgery, and daily for at least 10 days (or up to 35 days postoperatively) or until risk of deep venous thrombosis (DVT) has diminished or the patient is adequately anticoagulated on warfarin. The American College of Chest Physicians recommends initiation ≥12 hours preoperatively or ≥12 hours postoperatively; extended duration of up to 35 days suggested.
