Risk Stratification for Venous Thromboembolism in Hospitalized Medical Patients

Risk Stratification for Hospital-Acquired Venous Thromboembolism in Medical Patients: a Prospective Cohort Study

Hospital-acquired venous thromboembolism (HA-VTE) is one of the leading preventable causes of in-hospital mortality, but prevention of VTE in hospitalized medical patients remains challenging, as preventive measures such as pharmacological thromboprophylaxis (TPX) need to be tailored to individual thrombotic risk.

The broad objective of this project is to improve VTE prevention strategies in hospitalized medical patients by prospectively examining VTE risk factors (including mobility) and comparing existing risk assessment models.
