The most common trigger of hospitalization for venous thromboembolism was infection, accounting for 52 percent of the cases, the study authors found.
Besides infection, medications used to treat anemia and blood transfusions were also associated with greater risk of venous thromboembolism. Anemia drugs increased the risk ninefold, according to the report.
Other risk factors included surgery, fractures, being immobile and having had chemotherapy, the researchers pointed out.
Venous thromboembolism is a serious problem, with more than 330,000 Americans hospitalized for it each year, the authors noted.
"Since infection can occur anywhere, it is important that people know that something this common can result in a blood clot," Rogers said.
Therefore, it is important that preventive measures are a part of daily life, she added. "This includes getting your seasonal flu shot and other recommended vaccinations. This also includes practicing good hygiene and other measures to prevent infection, such as covering your cough," Rogers advised.
In addition, treatments are available to prevent clotting, including anticoagulants and compression stockings.
"Individuals who are already at higher risk of blood clots, for example, those who are overweight, older, had surgery or a bone fracture, or who have limited mobility, should take precautions," Rogers said.
Dr. Eric Gandras, associate chief of the division of vascular/interventional radiology at North Shore University Hospital in Manhasset, N.Y., said that "these researchers have identified risk factors for venous thromboembolism that are underappreciated compared to some of the other known risk factors."
Increased awareness can lead to increased preventive measures and more investigation of how infections result in v
