There are nearly 800,000 strokes in the United States each year, and more than 50% of stroke patients are readmitted or die within one year of discharge. Up to 90% of stroke survivors experience residual functional deficits that significantly impact their quality of life, yet it is estimated that up to 40% of all strokes can be prevented with good blood pressure control.
Learn how AI can help healthcare organizations (HCOs) reduce the incidence of initial strokes, improve secondary stroke prevention, and improve care planning and rehabilitation efforts. Discover how AI can help to proactively identify high-risk individuals, surface modifiable risk factors for stroke survivors, and anticipate and address functional outcomes and adverse events.

Cerebrovascular disease is the fourth leading cause of death among women, the fifth leading cause of death among men, and is a leading cause of serious long-term disability.¹ There are nearly 800,000 strokes in the United States each year, and more than 50% of stroke patients are readmitted or die within one year of discharge.²𝄒³ The incidence of stroke increases with age. Approximately 50% occur in people older than 75, and stroke is the second leading cause of hospital admission among the elderly.¹𝄒⁴ Notably, mortality from cerebrovascular disease is increasing significantly among younger adults and has risen by 36% in recent years.¹
The total cost associated with stroke is immense, averaging approximately $50 billion annually.⁵ Despite recent improvements in acute stroke treatment, more than one-third of patients are functionally dependent or have died within three months of a stroke. Moreover, up to 90% of stroke survivors are left with residual functional deficits that significantly impact quality of life and may increase risk of further adverse outcomes.² For example, immobility limits cardiovascular exercise and increases the risk for recurrent stroke and cardiovascular illness. Nearly one in four strokes occur in people who have previously had a stroke.⁵
Preventive interventions that account for modifiable risk factors can potentially reduce the incidence of stroke in high-risk patients. To this end, predictive analytics are critical for proactively and accurately identifying such patients and helping to facilitate proven interventions on an individual level. Interventions that address hypertension—a risk factor for 90% of all strokes—have proven to be effective, and it is estimated that up to 40% of all strokes can be prevented with good blood pressure control.⁶ Similarly, self-management interventions can significantly reduce risk. Smoking is associated with up to four times increased risk of stroke, and frequent exercise can reduce risk by up to half.⁶ For patients who have had a stroke, multidisciplinary rehabilitation programs remain the mainstay of treatment to improve outcomes and prevent secondary strokes.²
