Medically ill patients have a 10% chance of developing a DVT, while hospital-acquired DVTs and PEs occur in 10-33% of all hospitalized patients. Thrombophlebitis in this patient population is promoted by a combination of hypercoagulability and venous stasis. [76] Surgery, trauma, and immobilization also predispose to venous thromboembolism formation. Surgery without anticoagulation is associated with an incidence rate of DVT from 15-64%, while as many as 58% of patients entering trauma units have a DVT. [77, 78]
