Although the efficacy of anticoagulant therapy has been established for man
y conditions that are prevalent among the elderly population, the decision
to initiate anticoagulant therapy in the elderly population is not straight
forward because elderly patients with multiple comorbidities and varying le
vels of functional status are not routinely included in clinical trials of
efficacy. The true benefits of anticoagulant therapy will be realized when
health care providers and elderly patients can accurately assess the absolu
te risk versus the benefit associated with anticoagulant therapy.
