Stroke remains the leading cause of neurological disability and the th
ird leading cause of death worldwide, consuming a large share of total
healthcare expenditures. In this review, we discuss the cost effectiv
eness of stroke prevention for various risk factor-modification progra
mmes and pharmacological interventions with aspirin (acetylsalicylic a
cid), ticlopidine and warfarin. Cost considerations and potential cost
savings resulting from acute treatment are discussed for parenterally
administered anticoagulants, such as heparin and nadroparin, and for
intravenous thrombolysis with alteplase (recombinant tissue plasminoge
n activator; r-tPA). Patients with multiple risk factors for stroke re
quire more aggressive prevention strategies which are associated with
a greater risk of complications. The rates of complications, particula
rly intracerebral haemorrhage, should be kept low to achieve cost bene
fits for warfarin and alteplase. Reduced hospital length of stay is th
e key factor in the implementation of cost-effective stroke therapies.
The analysis of future clinical trials of new stroke therapies should
also include economic parameters, such as length of hospital stay and
intensity of resource usage, to help guide formulary and therapeutic
decisions.
