In their subgroup analysis of the Prospective Evaluation of Dalteparin Efficacy for Prevention of Venous Thromboembolism (VTE) in Immobilized Patients (PREVENT) Trial on the efficacy and safety of fixed low-dose dalteparin, Kucher et al1 found that in elderly patients, dalteparin use is associated with a similar relative risk reduction as in younger patients and conclude that a fixed low dose of dalteparin is effective and safe in preventing VTE in elderly hospitalized medical patients.
