Venous thromboembolism rates ranged from 0.6-3.2% and pulmonary embolism rates ranged from 0.28%-1.09%. Use of pharmacologic prophylaxis generally increased between 2003/4 and 2007/8. Venous thromboembolism rates, however, were not significantly affected among patients who received pharmacologic prophylaxis, and actually decreased among patients who did not receive any pharmacologic prophylaxis.
