About 600,000 such events occur each year in the United States, and the Johns Hopkins researchers estimate that one in six die from it. An estimated 100,000 to 200,000 of them are said to be healthcare-associated. Yet experts say that no more than half of patients who should receive some form of prevention strategy, whether medication or mechanical compressions on their legs, do.
That's because clinicians forget, don't appropriately see their patients as high risk, or because they worry that certain medications may cause some of their patients to bleed.
Haut says that prior to the creation of the hospital-wide computerized physician order entry system, prophylaxis rates hovered around 40% to 60%, but afterwards, rates of preventive care increased to 85% for 1,599 trauma patients included in the study.
