World Thrombosis Day

Tools for Healthcare Professionals

World Thrombosis Day (WTD) is focused on venous thromboembolism (VTE) and hospitalization as a leading risk factor for VTE. Despite the fact that VTE can be prevented, patients at high risk for developing the condition often don’t receive life-saving prevention. Through education and outreach, WTD hopes to reduce VTE-related death - the majority of which is hospital-associated - by encouraging healthcare professionals to open their eyes to thrombosis.

WTD is a timely opportunity to discuss, update or establish your organization’s VTE policy. Preventing clots is a patient safety issue and should be a standard of care for all hospitalized patients. Policies should engage all staff involved in patient care and strive for high compliance. While there is no universal policy on VTE prevention, several models exist.
