Extended use of anti-clotting drug helps some bedridden patients

A treatment plan used to prevent potentially dangerous blood clots in recovering surgical patients can also benefit some patients immobilized by acute medical illness, doctors have found in a multi-institutional study. In women, patients age 75 or older, and patients strictly confined to 24-hour bed rest, a month of extended treatment with a blood thinner significantly reduced the chances of blood clots while only slightly increasing the risk of bleeding. 

$3.7 million trial uses genes to balance risks, benefits of blood thinner

A five-year, $3.7 million clinical trial will investigate how to balance the benefits and risks of warfarin, a drug that helps prevent potentially deadly blood clots. The multicenter study, led by researchers at Washington University School of Medicine in St. Louis, will evaluate customized warfarin dosage based on patient genetics and will test which range of blood clotting is optimal in orthopedic patients.
