Clinical Trial Summary

Arterial and venous thromboembolism represents one of the most common preventable health problems. Patients undergoing surgery, especially hip fracture surgery are at high risk for deep vein thromboembolism (VTE) without thromboprophylaxis. In the absence of prophylaxis, the incidence of fatal pulmonary embolism (PE) after Hip Fracture Surgery (HFS) is reportedly 4%-12%. Provision of thromboprophylaxis to all patients who undergo HFS is recommended.


Description:

Rivaroxaban is the first agent of a new class of drugs acting as direct factor Xa inhibitors with oral bioavailability. Highly selective inhibition of factor Xa by rivaroxaban is expected to inhibit the amplified burst of thrombin generation and may result in more effective inhibition of thrombus formation with a favorable safety profile. In Thailand rivaroxaban is indicated for the prevention of VTE in patients undergoing major orthopedic surgery of the lower limbs including surgery for hip fractures. There are limited number of observational studies of rivaroxaban in thromboembolism after hip fracture surgery as the approved indication in most countries are for thromboprophylaxis in hip and knee arthroplasty. The broader indications and the high number of hip fracture surgeries in Thailand allow us to explore a pattern of safety profile particularly bleeding complications and risk factors in patients receiving rivaroxaban thromboprophylaxis after hip fracture surgery.
