Sampling Method:   Non-Probability Sample
Study Population

Patients who will be treated with rivaroxaban or other pharmacologic agents (e.g. LMWH/VKA/Fondaparinux) to prevent VTE after elective total hip replacement or total knee replacement


Inclusion Criteria:

  • Female and male patients >/= 18 years of age who will undergo elective total hip replacement or total knee replacement and receive Xarelto or other pharmacologic standard of care Venous Thromboembolism (VTE) prophylaxis, and who consent to participate in the study

Exclusion Criteria:

  • Patients with hypersensitivity to any pharmacologic VTE prophylaxis treatment
  • Patients with clinically significant active bleeding (e.g., intracranial bleeding, gastrointestinal bleeding)
  • Patients with significant hepatic disease which is associated with coagulopathy leading to a clinically relevant bleeding risk
  • Pregnant or lactating women
  • Patients with hereditary problems of lactose or galactose intolerance (e.g., the Lapp lactase deficiency or glucose-galactose malabsorption)
