The analysis looks at how specialized stroke services across the world have been effective in improving acute and long-term outcomes for patients.
Stroke is the third largest cause of death in the US, Europe, Canada and Japan. In England, around 110,000 people experience a stroke every year and 795,000 in the US.
Researchers from the University of Texas studied how stroke services are developing and looked in particular at current and emerging therapies in acute ischemic stroke, in which a patient experiences the death of an area of brain tissue resulting from an inadequate supply of blood and oxygen to the brain due to blockage of an artery.
In ischemic stroke cases, between 50% and 70% of survivors regain functional independence, while 15-30% are permanently disabled and 20% need institutional care three months after the stroke.
Early management of patients with this form of stroke is aimed at minimizing disability and improving a person's functioning, say the researchers.
Over the past decade, new therapeutic options have become available for stroke patients, says the analysis, including organized stroke care and primary stroke centers - specialized facilities which coordinate and promote patient access to the full range of treatments and services associated with stroke prevention, treatment and rehabilitation.
These centers (similar to specialist stroke centers in the UK) can provide emergency medical services for first-line response and initial stabilization; emergency department for hyperacute stroke care; acute stroke team availability within 15 minutes; neuroimaging and laboratory services in-house; stroke unit with treatment and secondary prevention; neurointerventional and neurosurgical services available; rehabilitation; primary prevention; community education and continuing medical education; and outcome and quality improvement activities.
The authors conclude: "The development of acute stroke centers and systems of care may revolutionize the medical community's ability to treat patients with stroke. Specialized stroke services have been effective in improving acute and long-term care outcome measures.
"Focusing clinical resources in neurocritical care units and stroke units provides greater specialist care, enhances knowledge in the field, and may also facilitate data collection and enrollment in clinical trials."
