Electronic alerts cut VTE in high-risk patients.(Gynecology)
NEW ORLEANS -- An automated electronic alert program aimed at physicians responsible for high-risk patients not receiving prophylaxis against venous thromboembolism resulted in a substantial reduction in thromboembolic events in a large randomized trial, Nils Kucher, M.D., said at the annual scientific sessions of the American Heart Association.
"Our results suggest that hospitals with adequate information system resources should consider implementation of electronic alerts to increase the awareness of venous thromboembolism [VTE] risk, improve utilization of prophylaxis, and reduce rates of leg deep vein thrombosis and pulmonary embolism," said Dr. Kucher of Brigham and Women's Hospital, Boston.
Studies have consistently shown that mechanical as well as pharmacologic prophylaxis against VTE is underutilized in at risk patients.
In an effort to rectify this situation, Dr. Kucher and his coworkers developed a computer program to electronically search the medical records of in-hospital patients and identify those at increased risk for VTE who were not receiving prophylaxis.
The program sent an e-mail alert to the physician in charge of the patient's care that included mention of the full range of prophylactic options, such as compression stockings, low-molecular-weight heparin, unfractionated heparin, warfarin, and pneumatic compression boots. The physician was then forced to acknowledge the alert but could choose to order or withhold prophylaxis.
The randomized trial involved 2,506 consecutive hospitalized patients at high risk for VTE who were not on prophylaxis. Physicians responsible for those in the intervention arm were issued an electronic alert.
The alert was withheld from physicians caring for patients in the control group.
